The Alphacool ES Jet CPU cooler was specially developed for powerful processors on Intel's LGA 4677 socket in server and workstation systems. What is new is that for the first time the water is distributed over four nozzles over the radiator floor. With the help of this nozzle technology, all cores of the processor are optimally covered and thus cooled more effectively and precisely. Thanks to the change from one to four nozzles, the ES Jet CPU cooler is able to reliably dissipate waste heat of up to 800 watts. Performance oriented! The cooler floor has been specially optimized for the large processor cores. The four nozzles of the ES Jet are not milled, but of course incorporated into the cooler. The organic water flow ensures an uninterrupted flow of water and thus increases the cooling capacity. The entire cooler is made of nickel-plated copper. Copper offers almost twice the thermal conductivity of aluminum and is therefore more suitable, especially in server or workstation systems. Space optimized! Despite the large radiator floor and the four nozzles, the ES Jet is compact and flat. So that the cooler can be installed in server racks without any problems, the connections are located on the side to save space. thermal paste The included thermal compound is Alphacool's Subzero with a thermal conductivity of 16 W/mK. The electrically non-conductive Thermal Grease is particularly well suited for high contact pressures, but due to its viscosity of 3,000,000mPa. s still process perfectly. Compatibility: Intel: LGA 4677 AMD: SP5 LGA 6096 (Optional if available)
