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.
At idle the cooler was quiet, but turned out only average results.
At load, again the VCT-9000 wasn't making too much noise, but you can see the lack of surface area and the slow speed of the fan did come at a cost to performance.
42 dB is a very respectable rating and I would in fact consider this a "quiet" solution to cooling.
Even with everything fully loaded and the fan at full go, it is one of the top ten quietest fans I have had the pleasure not to hear.
