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.
The Cooljag SFO-D(18SC) is one of the louder K8 heatsinks as illustrated by its position on this list of reference heatsinks. The 6800 RPM fan generated about 64 dBA worth of noise according to our measurements, so noise outside of the computer case will be unavoidable. If used with AMD Opteron processors in a racked workstation, this aspect of the Cooljag SFO-D(18SC)'s performance is unlikely to be of much importance however.
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 Cooljag SFO-D(18SC) heatsink has a base surface roughness of approximately 8 microinches, which is very good.... so no lapping required. Next, let's see how this heatsink handles the heat compared to a selection of other K8 heatsinks!
