The Alphacool ES Jet CPU cooler was specially developed for high-performance processors on Intel's LGA 4677 socket in server and workstation systems. With the supplied bracket, the Alphacool ES Jet CPU cooler now also supports the SP5 socket from AMD. A new feature is that the water is distributed across the base of the cooler via four nozzles for the first time. 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 up to 800 watts of waste heat. Performance orientated! The base of the cooler has been specially optimised for the large processor cores. The four nozzles of the ES Jet are not milled, but naturally incorporated into the cooler. The organic water feed ensures a turbulence-free water flow and thus increases the cooling capacity. The entire radiator is made of nickel-plated copper. Copper offers almost twice the thermal conductivity of aluminium and is therefore particularly suitable for server or workstation systems. Space-optimised! Despite the large radiator base and the four nozzles, the ES Jet has a compact and flat design. The connections are located on the top to save space so that the cooler can be installed in server racks without any problems. Thermal grease The thermal grease included in the scope of delivery is Alphacool's Subzero with a thermal conductivity of 16 W/mK. The electrically non-conductive thermal grease is particularly suitable for high contact pressures, but can still be processed perfectly due to its viscosity of 3,000,000 mPa. s.
