Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
Temperature at idle was a bit more than the CoolIt ECO, well over a degree. I looked for the reasoning behind it and did some testing. What I had found is that the head unit on the pump is very warm, almost hot to the touch when just the pump is cycling. On the flip side, the CoolIT uses a very low wattage pump and their head unit doesn't feel warm when operational.
At load, temperatures really started to even out. With two tenths of a degree difference at load, I have to say they are both pretty good at what they do, cooling the processor at load.
Fan noise is very similar between the two at idle. As I mentioned, noise level is subjective here. Most of us are going to swap fans and toy around with them to achieve either better cooling performance or lower sound levels with similar performance.
With everything maxed out the H50 does pull ahead of the ECO in noise levels and at 8dB difference, it is slight. But for those who have to get the quietest stock solution, I think Corsair takes this one.
