MORE INFO

A CPU water block is an important part of the CPU water cooling system. When a water cooling system works, the CPU water block clings to the CPU and directly absorbs heat. Afterwards, the water cooling liquid circulates in the system and takes away the heat quickly. A fan based air cooling system works on the same principle, but doesn’t work as well because the air has lower thermal conductivity and smaller specific heat capacity than the water cooling liquid.

If you look to play PC games, it’s necessary to keep your CPU cool so that it reaches its best performance. As those cheap air cooling systems no longer achieves your demand, a water cooling system is definitely what you need. In that case, you need to find the best CPU water block for your pc.
