What is a water block?


Water blocks are made from two main parts, the body  that is made up of Acrylic or Acetal (POM) and the metal bases touching the components are copper, nickel plated copper or aluminum. They are designed to transfer heat from the various components to the liquid in the system through machined channels and specially designed pressure plates that increase flow rate and cooling surface. The GPU water blocks cool numerous hot spots on the PCB of the graphics card to ensure you get the ultimate cooling performance. This is why GPU water blocks are specifically manufactured to each GPU’s own PCB.


How can water blocks influence overall temperatures?


Water blocks could be turned 90° on some CPU’s and it could have slight temperature variation but in general not enough to have more than a 2 C° difference. Water blocks also need routine cleaning and maintenance because of precipitation build up that will take place in between the fins on the pressure plates over time. This precipitation blockage will raise your temperatures and could cause overheating. The same build-up could cause pressure in the system that might pop your tubing out of a fitting resulting in a leak.
