This sealed dual-socket server liquid cooler arrives pre-assembled, pre-filled, and pre-bled with two CPU blocks, an inline pump, tubing, and a 4x80mm radiator. Nothing is opened, filled, or bled during installation.

High-core-count AMD EPYC processors run sustained server workloads where air heatsinks dump heat across memory and drives. This closed loop routes heat from both SP5 sockets directly out the chassis exhaust. The 7000 RPM inline pump sits in the tubing rather than on the motherboard, eliminating vibration at the CPU sockets while maintaining even contact pressure.

Warnings

Warranty is repair or replacement. Returns are accepted within 30 days, no questions asked. A restocking fee applies to every return, with a higher fee for items that have been installed or used.

The loop is sealed, pre-filled and pre-bled: do not open it, modify the tubing or top it up, which can cause a leak or a pump failure. Thermal paste goes on the CPU's integrated heat spreader; there are no thermal pads. Tighten the four mounting screws in their numbered order, in a cross pattern, finger tight.

The manufacturer reserves the right to alter the design to expand compatibility, so the delivered item may not match the pictured item exactly.
