All copper water block Liquid heat exchanger to rapidly remove heat from CPUs, Xbox CPUs, GPUs, video cards, IGBTs, power electronics, lasers, peltier TECs or power generation TEGs. Most efficient method of removing heat from electronics.

Heat removal is 4 to 5 times greater with this water block than using just a finned heat sink.

Components can be mounted to one or both sides thereby allowing heat removal from two 40x40mm TECs or other electronic components at the same time.

All copper construction allows for parts and components to be soldered to cold plate for maximum thermal conduction.

Superior manufacturing, CNC machined from solid copper. Do not confuse this cold plate (water block) with inferior cheap water blocks that will NOT deliver on cooling ability. You get what you pay for.
