Leave it up to the German's to take a simple heatsink and mix in Cold Gas Dynamic Spray technology, a 3mm thick copper base plate, and top it off with a completely revolutionary CAIRdB fan. As if that isn't enough already, the temperature sensitive 80251235-KP2 CAIRdB fan is virtually silent under power, and is even held in place on the aluminum heatsink with four vibration dampening rubber posts. All of this engineering comes from one company by the name of Verax Ventilatoren GmbH and I have a feeling this is going to make for one very interesting heatsink review... Though before we touch on what exactly Cold Gas Dynamic Spraying has to do with making the Verax P14Cu heatsink 'better', let's focus for a second on that crazy looking fan below.The Verax CAIRdB thermally controlled fans are one the most unique zero-noise fans in the marketplace that we have tested. The stealthy acoustical act is accomplished by tossing out convention and starting with a completely fresh impeller design. It's not surprising to discover that the company that created these fans has its background in research & development of fluid engineering.
