Acoustic Samples: Listen to this
SFO-H (68YC) heatsink operates at two extremes with respect to fan
noise. At its slowest fan speed the cooler generates 43.0 dBA, while at full speed the fan creates 60.6 dBA. To
listen to this heatsink in operation, be sure to click on the headphones icons
below and play the each of the sample MP3 files.

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-H (68YC) heatsink covers both noise level extremes. With the fan dialed down to the slowest RPM setting it is effectively a low noise heatsink. However, when the fan is running at its full speed it is quite loud. The user has no direct control over fan speed because this aspect is controlled exclusively by the fans' thermistor. If ambient case temperatures remain low the fan speed many never rise above the 3000RPM level.
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-H (68YC) heatsink has a surface roughness of approximately ~32 microinches, which is considered pretty good. Next, let's see how this heatsink handles the heat compared to a selection of other Athlon64 K8 heatsinks!
