72-458: The line is positioned above LOQ and currently competes against other high-end gaming PCs such as HP's Omen , Acer's Predator , Asus ' ROG and Dell's Alienware subsidiary. At E3 2018 , Lenovo announced three new laptops with new redesigned chassis, Y530, Y730 and Y7000. In 2019, Lenovo introduced the Legion Y540, Y740 with the new GeForce 20 series. In 2020, Lenovo launched

144-455: A T-Line . More recently a growing number of companies are manufacturing water-cooling components compact enough to fit inside a computer case. This, and the trend to CPUs of higher power dissipation, has greatly increased the popularity of water cooling. Dedicated overclockers have occasionally used vapor-compression refrigeration or thermoelectric coolers in place of more common standard heat exchangers. Water cooling systems in which water

216-482: A boiling point temperature of around 100 degrees C at atmospheric pressure. Engines operating at higher temperatures may require a pressurized recycle loop to prevent overheating. Modern automotive cooling systems often operate at 15 psi (103 kPa) to raise the boiling-point of the recycling water coolant and reduce evaporative losses. The use of water cooling carries the risk of damage from freezing. Automotive and many other engine cooling applications require

288-498: A fluid being cooled, or contact cooling water may directly impinge on items like saw blades where phase difference allows easy separation . Environmental regulations emphasize the reduced concentrations of waste products in non-contact cooling water. Water accelerates the corrosion of metal parts and is a favorable medium for biological growth. Dissolved minerals in natural water supplies are concentrated by evaporation to leave deposits called scale. Cooling water often requires

360-493: A recirculating system or used in a single-pass once-through cooling (OTC) system. Water's high enthalpy of vaporization allows the option of efficient evaporative cooling to remove waste heat in cooling towers or cooling ponds . Recirculating systems are open if they rely upon evaporative cooling or closed if heat removal is accomplished in heat exchangers , thus with negligible evaporative loss. A heat exchanger or condenser may separate non-contact cooling water from

432-466: A shareholder rights plan to fend off Xerox's pursuit of a hostile takeover . Four days later, HP announced that, if shareholders rejected the Xerox purchase, it planned on offering $ 16 billion in capital return between fiscal 2020 and 2022, including $ 8 billion in additional share buybacks and raising its "target long-term return of capital to 100% of free cash flow generation". HP criticized Xerox's bid as

504-554: A "flawed value exchange" based on "overstated synergies". On March 5, 2020, HP rejected an offer at $ 24 per-share. On March 31, 2020, Xerox rescinded its bid to buy HP Inc, citing that "the current global health crisis and resulting macroeconomic and market turmoil " had "created an environment that is not conducive to Xerox continuing to pursue an acquisition of HP Inc." HP develops personal computers (PCs), printers and related supplies, as well as 3D printing services. Its consumer PCs have been marketed under brands such as

576-619: A 3-year sleeve sponsorship deal with Real Madrid , being the first sleeve sponsor of the club's 121-year history. In April 2024, it was announced HP had signed a "multi-year" deal to become the title sponsor for the Scuderia Ferrari Formula One team, extending to the team's F1 Academy and esports programmes. The HP logo will feature on both the team's 2024 car, the Ferrari SF-24 , and the race suits of drivers Carlos Sainz Jr. and Charles Leclerc . Alongside

HOP argues these practices force consumers to purchase new cartridges unnecessarily, contributing to waste and environmental harm. 37°24′40″N 122°08′52″W  /  37.4111842°N 122.1476929°W  / 37.4111842; -122.1476929 CPU water cooling Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water

720-456: A closed system. Biofouling occurs because water is a favorable environment for many life forms. Flow characteristics of recirculating cooling water systems encourage colonization by sessile organisms using the circulating supply of food, oxygen and nutrients. Temperatures may become high enough to support thermophilic populations of organisms such as types of fungi . Biofouling of heat exchange surfaces can reduce heat transfer rates of

792-725: A comfortable ambient temperature. Some nuclear reactors use heavy water as coolant. Heavy water is employed in nuclear reactors because it is a weaker neutron absorber . This allows for the use of less-enriched fuel. For the main cooling system, normal water is preferably employed through the use of a heat exchanger, as heavy water is much more expensive. Reactors that use other materials for moderation (graphite) may also use normal water for cooling . High-grade industrial water (produced by reverse osmosis or distillation ) and potable water are sometimes used in industrial plants requiring high-purity cooling water. Production of these high-purity waters creates waste byproduct brines containing

864-442: A cooling water system is reported as the pH level. Low pH values increase the rate of corrosion; high pH values encourage scale formation. Amphoterism is uncommon among metals used in water cooling systems, but aluminum corrosion rates increase with pH values above 9. Galvanic corrosion may be severe in water systems with copper and aluminum components. Acid can be added to cooling water systems to prevent scale formation if

936-476: A film of gamma iron oxide and zinc phosphate can inhibit corrosion by passivating anodic and cathodic reaction points. These increase salinity and total dissolved solids, and phosphorus compounds may provide the limiting essential nutrient for algal growth contributing to biofouling of the cooling system or to eutrophication of natural aquatic environments receiving blowdown or OTC water. Chromates reduce biofouling in addition to effective corrosion inhibition in

1008-426: A fraction of recirculating water as blowdown to remove dissolved solids at concentrations low enough to prevent scale formation. Some open systems use inexpensive tap water , but this requires higher blowdown rates than deionized or distilled water . Purified water systems still require blowdown to remove the accumulation of byproducts of chemical treatment to prevent corrosion and biofouling. Water for cooling has

1080-429: A high rate of flow. These structures tend to also pull in large numbers of fish and other aquatic organisms, which are killed or injured on the intake screens . Large flow rates may trap slow-swimming organisms including fish and shrimp on screens protecting the small bore tubes of the heat exchangers from blockage. High temperatures or pump turbulence and shear may kill or disable smaller organisms that pass through

1152-615: A low temperature throughout the year. Systems operating with seawater need to be manufactured from cupronickel , bronze , titanium or similarly corrosion-resistant materials. Water containing sediment may require velocity restrictions through piping to avoid erosion at high velocity or blockage by settling at low velocity. Plant transpiration and animal perspiration use evaporative cooling to prevent high temperatures from causing unsustainable metabolic rates . Machine guns used in fixed defensive positions sometimes use water cooling to extend barrel life through periods of rapid fire, but

1224-478: A measured volume of filtered water is evaporated . Salinity indicates water density or conductivity changes caused by dissolved materials. Probability of scale formation increases with increasing total dissolved solids. Solids commonly associated with scale formation are calcium and magnesium both as carbonate and sulfate . Corrosion rates initially increase with salinity in response to increasing electrical conductivity, but then decrease after reaching

1296-563: A peak as higher levels of salinity decrease dissolved oxygen levels. Some groundwater contains very little oxygen when pumped from wells, but most natural water supplies include dissolved oxygen. Increasing oxygen concentrations accelerate corrosion. Dissolved oxygen approaches saturation levels in cooling towers. It is beneficial in blowdown or OTC water being returned to natural aquatic environments. Water ionizes into hydronium (H 3 O ) cations and hydroxide (OH ) anions . The concentration of ionized hydrogen (as protonated water) in

1368-408: Is a consideration when siting such plants. Water returned to aquatic environments at temperatures higher than the ambient receiving water modifies aquatic habitat by increasing biochemical reaction rates and decreasing the oxygen saturation capacity of the habitat. Temperature increases initially favor a population shift from species requiring the high-oxygen concentration of cold water to those enjoying

1440-403: Is a solution to ensure the optimisation of energy efficiency while simultaneously minimising noise and space requirements. Especially useful in supercomputers or Data Centers because maintenance of the racks is quick and easy. After disassembly of the rack, advanced-technology quick-release couplings eliminate spillage for the safety of operators and protect the integrity of fluids (no impurities in

1512-483: Is an American multinational information technology company headquartered in Palo Alto, California , that develops personal computers (PCs), printers and related supplies, as well as 3D printing services. Founded in 2015 as the successor of the original Hewlett-Packard , HP Inc. is the world's second-largest personal computer vendor by unit sales after Lenovo and ahead of Dell , as of 2024.

1584-417: Is cooled directly by the evaporator coil of a phase change system are able to chill the circulating coolant below the ambient air temperature (impossible with a standard heat exchanger) and, as a result, generally provide superior cooling of the computer's heat-generating components. The downside of phase-change or thermoelectric cooling is that it uses much more electricity, and antifreeze must be added due to

1656-418: Is often more efficient than air cooling . Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations . Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs and other components. Other uses include

1728-419: Is required and it has to be carefully controlled. Modern solid-state transmitters can be built so that even high-power transmitters do not require water cooling. Water cooling is however also sometimes used for thyristors of HVDC valves, for which the use of deionized water is required. Liquid cooling techniques are increasingly being used for the thermal management of electronic components. This type of cooling

1800-661: Is required only in that localized area. The disadvantage of such a system is higher power dissipation. To avoid damage from condensation around the Peltier junction, a proper installation requires it to be "potted" with silicone epoxy. The epoxy is applied around the edges of the device, preventing air from entering or leaving the interior. Apple's Power Mac G5 was the first mainstream desktop computer to have water cooling as standard (although only on its fastest models). Dell followed suit by shipping their XPS computers with liquid cooling , using thermoelectric cooling to help cool

1872-846: Is required. Chlorine may be added in the form of hypochlorite to decrease biofouling in cooling water systems, but is later reduced to chloride to minimize the toxicity of blowdown or OTC water returned to natural aquatic environments. Hypochlorite is increasingly destructive to wooden cooling towers as pH increases. Chlorinated phenols have been used as biocides or leached from preserved wood in cooling towers. Both hypochlorite and pentachlorophenol have reduced effectiveness at pH values greater than 8. Non-oxidizing biocides may be more difficult to detoxify prior to release of blowdown or OTC water to natural aquatic environments. Concentrations of polyphosphates or phosphonates with zinc and chromates or similar compounds have been maintained in cooling systems to keep heat exchange surfaces clean enough that

1944-844: Is used for the CPU and GPUs . Water cooling typically uses a water block , a water pump , and a water-to-air heat exchanger. By transferring device heat to a separate larger heat exchanger using larger, lower-speed fans, water cooling can allow quieter operation, improved processor speeds ( overclocking ), or a balance of both. Less commonly, Northbridges , Southbridges , hard disk drives , memory , voltage regulator modules (VRMs), and even power supplies can be water-cooled. Internal radiator size may vary: from 40 mm dual fan (80 mm) to 140 quad fan (560 mm) and thickness from 30 mm to 80 mm. Radiator fans may be mounted on one or both sides. External radiators can be much larger than their internal counterparts as they do not need to fit in

2016-613: The Environmental Protection Agency (EPA) to issue regulations on industrial cooling water intake structures. EPA issued final regulations for new facilities in 2001 (amended 2003), and for existing facilities in 2014. As an alternative to OTC, industrial cooling towers may use recirculated river water, coastal water ( seawater ), or well water. Large mechanical induced-draft or forced-draft cooling towers in industrial plants continuously circulate cooling water through heat exchangers and other equipment where

2088-619: The Essential line and Pavilion (consumer), Envy and Spectre (high-end and prosumer ), and Omen ( gaming ). HP's business computers are marketed under the "Pro" and "Elite" prefixes. It also manufactures the DeskJet , OfficeJet, and LaserJet series of printers. In the professional space, HP market the HP Z series of desktop workstations and its mobile equivalent, HP ZBook . In March 2015, HP announced that Bang & Olufsen would become

2160-588: The Israeli Police , Israeli Prison Service , and Israeli Population and Immigration Authority . The BDS movement has called for consumers and organizations to boycott all HPE IT services and products as well as printers, computers, and printer cartridges from HP Inc. A French association called Halte à l'Obsolescence Programmée (HOP) has filed a complaint against the printer manufacturer HP, accusing it of planned obsolescence practices. The complaint alleges that HP artificially blocks printers when it detects

2232-456: The heater core . Also, the water jacket around an engine is very effective at deadening mechanical noises, making the engine quieter. An open water cooling system makes use of evaporative cooling , lowering the temperature of the remaining (unevaporated) water. This method was common in early internal combustion engines until scale buildup was observed from dissolved salts and minerals in the water. Modern open cooling systems continuously waste

2520-431: The addition of chemicals to minimize corrosion and insulating deposits of scale and biofouling. Water contains varying amounts of impurities from contact with the atmosphere, soil, and containers. Being both an electrical conductor and a solvent for metal ions and oxygen, water can accelerate corrosion of machinery being cooled. Corrosion reactions proceed more rapidly as temperature increases. Preservation of machinery in

2592-446: The advantages of increased metabolic rates in warm water. Once-through cooling (OTC) systems may be used on very large rivers or at coastal and estuarine sites. These power stations put the waste heat into the river or coastal water. These OTC systems thus rely upon an ample supply of river water or seawater for their cooling needs. Such facilities are built with intake structures designed for bringing in large volumes of water at

2664-414: The ambient temperature while obviating the requirement for antifreeze and lagged pipes, is to place a thermoelectric device (commonly referred to as a 'Peltier junction' or 'pelt' after Jean Peltier , who documented the effect) between the heat-generating component and the water block. Because the only sub-ambient temperature zone now is at the interface with the heat-generating component itself, insulation

2736-517: The branding deal, HP will supply the team with services "ranging from computers, printers and other hardware to conferencing technology." HP reported total CO 2 e emissions for the twelve months ending October 31, 2023, at 19,764,400 tonnes CO 2 -equivalent and plans to reduce emissions 60% by 2025 from a 2015 base year. According to a press release issued on April 20, 2021, HP seeks to achieve net zero greenhouse gas emissions by 2040. In 2016, HP introduced firmware in its printers that disabled

2808-444: The cash amount agreed was $ 40 per share, which implied a total enterprise value of $ 3.3bn, inclusive Poly's net debts. On November 5, 2019, The Wall Street Journal reported that print and digital document company Xerox was contemplating acquiring HP. The company unanimously rejected two unsolicited offers, including a cash-and-stock offer at $ 22 per-share. HP stated that there was "uncertainty regarding Xerox's ability to raise

2880-407: The cash portion of the proposed consideration" (especially given that Xerox is a smaller company in terms of market cap than HP), and noted the company's aggressiveness. On November 26, 2019, Xerox issued a public letter defending allegations by HP that its offer was "uncertain" and "highly conditional", and declared its intent to "engage directly with HP shareholders to solicit their support in urging

2952-412: The circuits). These couplings are also capable of being locked (Panel mounted?) to allow blind connection in difficult-to-access areas. It is important in electronics technology to analyse the connection systems to ensure: Water cooling often adds complexity and cost in comparison to air cooling design by requiring a pump, tubing or piping to transport the water, and a radiator, often with fans, to reject

In May 2024, HP announced that its PC models would adopt a new branding nomenclature, with most of its consumer computer models (besides Omen) folded under the "Omni" brand, with " OmniBook " (a revival of the brand that

3096-463: The concentrated impurities from the source water. In 2018, researchers from the University of Colorado Boulder and University of Wyoming invented a radiative cooling metamaterial known as "RadiCold", which has been developed since 2017. This metamaterial aids in cooling of water and increasing the efficiency of power generation, in which it would cool the underneath objects, by reflecting away

3168-486: The confines of a computer case. High-end cases may have two rubber grommeted ports in the back for the inlet and outlet hoses, which allow external radiators to be placed far away from the PC. A T-Line is used to remove trapped air bubbles from the circulating water. It is made with a t-connector and a capped-off length of tubing. The tube n acts as a mini-reservoir and allows air bubbles to travel into it as they are caught into

3240-585: The cooling of lubricant oil in pumps ; for cooling purposes in heat exchangers ; for cooling buildings in HVAC and in chillers . Water is inexpensive, non-toxic , and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer. Cooling water may be recycled through

3312-654: The cooling system, and biofouling of cooling towers can alter flow distribution to reduce evaporative cooling rates. Biofouling may also create differential oxygen concentrations increasing corrosion rates. OTC and open recirculating systems are more susceptible to biofouling. Biofouling may be inhibited by temporary habitat modifications. Temperature differences may discourage the establishment of thermophilic populations in intermittently operated facilities, and intentional short-term temperature spikes may periodically kill less tolerant populations. Biocides have been commonly used to control biofouling where sustained facility operation

3384-421: The cooling water system, but residual toxicity in blowdown or OTC water has encouraged lower chromate concentrations and the use of less-flexible corrosion inhibitors. Blowdown may also contain chromium leached from cooling towers constructed of wood preserved with chromated copper arsenate . Total dissolved solids or TDS (sometimes called filterable residue) is reported as the mass of residue remaining when

3456-408: The efficiency of automotive cooling systems. Such products are used to enhance the cooling of underperforming or undersized cooling systems or in racing where the weight of a larger cooling system could be a disadvantage. Since approximately 1930 it is common to use water cooling for tubes of powerful transmitters. As these devices use high operation voltages (around 10 kV), the use of deionized water

3528-401: The evaporated pure water is replaced by make-up water containing carbonates and other dissolved salts, a portion of the circulating water is continuously discarded as "blowdown" water to minimize the excessive build-up of salts in the circulating water; these blowdown wastes may change the receiving water quality. The heated coolant mixture can be used to warm the air inside the car by means of

3600-587: The firmware was intended to provide "the best consumer experience" and "protect" customers from "counterfeit and third-party ink cartridges that do not contain an original HP security chip and that infringe on our IP ." In 2023, PC World reported that HP printers still prevent users from using third-party ink. In 2023, HP was sued over allegations that it intentionally designed its all-in-one printers not to perform scanning or faxing when they were low on ink. In February 2019, How-To Geek published an article reporting that HP remotely disabled ink cartridges when

3744-684: The heat source. Cooling hot computer components with various fluids has been in use since at least the Cray-2 in 1982, which used Fluorinert . Through the 1990s, water cooling for home PCs slowly gained recognition among enthusiasts, but it became noticeably more prevalent after the introduction of the first Gigahertz-clocked processors in the early 2000s. As of 2018, there are dozens of manufacturers of water cooling components and kits, and many computer manufacturers include preinstalled water cooling solutions for their high-performance systems. Water cooling can be used for many computer components, but usually it

3816-508: The heat to the atmosphere. Depending on the application, water cooling may create an additional element of risk where leakage from the water coolant recycle loop can corrode or short-circuit sensitive electronic components. The primary advantage of water cooling for cooling CPU cores in computing equipment is transporting heat away from the source to a secondary cooling surface to allow for large, more optimally designed radiators rather than small, relatively inefficient fins mounted directly on

In May and August 2016, certain assets were sold to OpenText , including TeamSite and Exstream . In November 2017, HP acquired Samsung Electronics ' printer division for $ 1.05 billion. In February 2021, HP announced its acquisition of Kingston 's gaming division HyperX for $ 425 million. The deal only includes computer peripherals branded as HyperX, not memory or storage. The sale

3960-485: The liquid. Currently, Dell's only computers to offer liquid cooling are their Alienware desktops. Asus are the first and only mainstream brand to have put water-cooled laptops into mass production. Those laptops have a built-in air/water hybrid cooling system and can be docked to an external liquid cooling radiator for additional cooling and electrical power. Water is an ideal cooling medium for vessels as they are constantly surrounded by water that generally remains at

4032-476: The low temperature. Additionally, insulation, usually in the form of lagging around water pipes and neoprene pads around the components to be cooled, must be used in order to prevent damage caused by condensation of water vapour from the air on chilled surfaces. Common places from which to obtain the required phase transition systems are a household dehumidifier or air conditioner . An alternative cooling scheme, which also enables components to be cooled below

4104-462: The pH decrease will offset increased salinity and dissolved solids. Few other cooling applications approach the large volumes of water required to condense low-pressure steam at power stations . Many facilities, particularly electric power plants, use millions of gallons of water per day for cooling. Water cooling on this scale may alter natural water environments and create new environments. Thermal pollution of rivers, estuaries and coastal waters

4176-654: The presence of hot water has been improved by addition of corrosion inhibitors including zinc , chromates and phosphates . The first two have toxicity concerns; and the last has been associated with eutrophication . Residual concentrations of biocides and corrosion inhibitors are of potential concern for OTC and blowdown from open recirculating cooling water systems. With the exception of machines with short design life, closed recirculating systems require periodic cooling-water treatment or replacement raising similar concern about ultimate disposal of cooling water containing chemicals used with environmental safety assumptions of

More than 1,200 power plants and manufacturing facilities in the U.S. use OTC systems; the intake structures kill billions of fish and other organisms each year. More-agile aquatic predators consume organisms impinged on the screens; and warm water predators and scavengers colonize the cooling water discharge to feed on entrained organisms. The U.S. Clean Water Act required

4536-518: The use of a water and antifreeze mixture to lower the freezing point to a temperature unlikely to be experienced. Antifreeze also inhibits corrosion from dissimilar metals and can increase the boiling point, allowing a wider range of water cooling temperatures. Its distinctive odor also alerts operators to cooling system leaks and problems that would go unnoticed in a water-only cooling system. Other less common chemical additives are products to reduce surface tension. These additives are meant to increase

4608-573: The use of involuntary labor of any kind. HP also commits to respecting fundamental rights and freedoms defined in the United Nations (UN) Universal Declaration of Human Rights (UDHR) in an approach consistent with the UN Guiding Principles on Business and Human Rights (UNGPs) as outlined in our Human Rights Policy." In 2023, HP as well as Hewlett Packard Enterprise (HPE) has come under criticism for its products provided to

In 2020, the Australian Strategic Policy Institute accused at least 82 major brands, including HP Inc, of being potentially connected to forced Uyghur labor in the Chinese Xinjiang province. In 2022, in response to the U.S. Uyghur Forced Labor Prevention Act , HP responded, "HP is committed to respecting human rights across our global supply chain and we prohibit

4752-433: The water absorbs heat. That heat is then rejected to the atmosphere by the evaporation of some of the water in cooling towers where upflowing air contacts the downflowing water. The loss of evaporated water into the air exhausted to the atmosphere is replaced by "make-up" fresh river water or fresh cooling water, but the amount of water lost during evaporative cooling may affect the natural habitat for aquatic organisms. Because
