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.

With idle testing completed I noticed that only the H70 is cooler at this point. Antec pulled ahead of the CoolIt ECO and the Corsair H50. Seems the component combination Antec chose from Asetek is a good match so far.

In load testing the results are much the same of the four in the chart. What I did notice is that the Antec made some headway towards the H70. In fact, testing showed an almost even performance.

Sound level, while not "quiet" like the box insinuated, it is below average as far as noise output goes. 46 dB is respectable for the amount of cooling the KUHLER H2O 620 is capable of.

At full load the 620 jumped right on up to the louder fans we have tested. 68 dB isn't screaming loud, as the Frio OCK set a new record there, but you will be able to notice a hum coming from the case with the use of the 620 under full load.
