The IceGiant ProSiphon Elite is a powerful and unique CPU cooler that brings the ProSiphon technology is based on the thermosiphon effect, a technique normally reserved for commercial or High-Performance Computing, to the home. Compatible with most modern AMD and Intel chipsets, the IceGiant ProSiphon Elite can achieve cooling performance comparable to a custom-made water cooling system.The IceGiant ProSiphon Elite CPU-Cooler at a glance:Compatible with AMD and Intel chipsetsUnique \'gravity-driven\' cooling loopFour integrated 120mm PWM fans includedVertical and horizontal mounting possibleIncludes high-performance Thermal Grizzly Kryonaut thermal pasteThe IceGiant ProSiphon Elite CPU-Cooler in detail:At first glance, the ProSiphon Elite appears to consist of a large heatsink and four 120mm PWM fans. However, this is no ordinary air cooler. It uses IceGiant\'s patented technology offers powerful cooling.This is a technique that has not been previously used for consumer applications. Essentially, a liquid dielectric at the bottom of the cooler will quickly evaporate once the CPU starts heating up. The evaporated liquid transfers the excess heat to the outer edges of the condenser, where the fans expel the heat from the cooler. The cooled liquid then returns to the bottom of the condenser, ready to start the process all over.ProSiphon Elites patented ProSiphon cooling process means the CPU cooler effectively dissipates heat, whilst its efficient design makes it extremely durable. So much so, youll be provided with a ten-year IceGiant warranty.As well as the condenser, four dedicated PWM fans are attached to the unit. Thermal Grizzly Kryonaut paste is also included to ensure strong heat transfer between the cooler and CPU.How ProSiphon Technology Works: A comparison with standard Heat PipesStandard air CPU Coolers make use of hollow chambers line with a wick and a small amount of coolant. Once the CPU begins heating, the excess heat is transferred via a contact plate to the heat pipes and the liquid begins to evaporate.As the vapour rises through the chamber, the excess heat moves from the cooler to numerous fins lining the edges of the cooler. Then cool air is blown on to the fins via fans, meaning the vapour cools back to its liquid form, which is absorbed by the wick.The issue with this process is that if the liquid is heated to excess levels, it begins to boil inside the hollow sections of the heatpipes. This means the liquid cannot be absorbed by the wick and it dries out.The end result is thermal throttling since there is no liquid to absorb the heat generated by the CPU. This is a particular problem with high performance CPUs, such as AMD\'s Ryzen Threadripper series, that have a TDP of 250 Watts or higherWith the ProSiphon Elite, IceGiant implements an alternative approach. The ProSiphon Elite takes advantage of the coolant\'s tendency to evaporate with a loop system that directs the vapour to follow through the unit, passing by fins to dissipate the heat and ultimately pushing the re-condensed vapour back to the base of the unit via gravity.Not only does this result in greater cooling than is typical of traditional air cooled CPU coolers but since there are fewer moving parts the ProSiphon Elite is extremely reliable. It is capable of operating continuously under heavy workloads.In fact, IceGiant are so confident of the ProSiphon\'s longevity that they provide a 10-year warranty.
