Sound Level Measurements: Which Heatsink is Quietest?
Listening to the actual noise a heatsink makes allows you to hear what pure numbers alone cannot get across. To further emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink, we also take noise level measurements with a sound level meter.
From the K8 heatsinks tested, we can see that the Dynatron A41 heatsink is in the middle of the list in terns of noise output. At 56dBA, it will be somewhat audible from outside the case.
Surface Finish Comparator Notes: Flatness and Finish
Surface finish is an important factor that we all look for when holding a new heatsink. Flipping a cooler over to see how well the base has been machined is a quick way to judge the attention to detail that was put into making it. The following test involves the use of a Surface Roughness Comparator, which offers a concise cross section common machine surface finishes.
The Dynatron A41 heatsink has a surface roughness of approximately 16 microinches, which is considered quite good. Next, let's see how this heatsink handles the heat compared to a selection of other heatsinks!
