TechREACTION Review: GELID Icy Vision Rev 2 GPU Cooler
 

In our 3D test, we see a difference of nearly 35c. It should also be noted that the GELID cooler is still as silent at this point as in its normal usage test! The stock cooler is jumping between 50%-85% fan speed and sounds like a jet engine on take off… or at least a very irritable hair dryer.
