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.
The GELID Silent Spirit holds its own in the torture chamber of testing we at TweakTown submit them to. While definitely not a record setting run, the cooler performed better than most of the competition at load. The Silent Sprit idled at 56.8° Celcius, while load temps weren't far from that, peaking at 62° Celcuis right on the nose. That leaves this cooler better than more than half of this list at load. Nice job done by GELID there.
This bit of the testing is where I was a little disappointed. With all the science and know-how put into the rest of this cooler, the noise levels weren't all that nice to have coming out of the test rig. Only three coolers did worse than the Silent Spirit in this category, one of those being the AMD stock cooler. Although even with its higher level of sound, 63dB at idle and 68dB at load, when the fan ramps up the difference is minimal. One thing I did notice that contributed to the noise factor is that once the fan runs at full speed on 12V power, the entire mounting system rattled against the fins. If GELID could somehow do away with that aspect, the noise levels would drop a bit.
