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.
To be honest, I am not entirely impressed with the single fan temperatures, or the dual fan results. I think Titan took silence a bit too far for the overclockers. For the average user these results are much better than a stock cooler will provide, and if silence is mandatory, this may still be a viable solution.
Load testing with the fans at full power isn't much more impressive than the idle results. Titan choosing these fans really produced average results. The Evo did better, but I think if Titan wants this silent of a cooler the fins and heat pipes need a bit of a redesign to make the Hati really shine.
Sound levels with two fans or a single fan are where I personally like my air cooling. 35 dB is very acceptable; too bad it wasn't able to help more with better temperatures.
The loudest results were found with both fans in operation. The results aren't that bad here either, but for a fan shipped as a silent solution to cooling, this shows it isn't exactly that when the system is loaded.
