Acoustic Samples: Listen to this
What a difference fan speed can make!
The Thermaltake Venus 12 heatsink weighs in at 42.6 dBA on the low
side, and runs at an incredibly loud 68.1 dBA with the fan at full speed. 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 Thermaltake Venus 12 covers both noise level extremes. With the fan dialed down to the slowest RPM it is effectively in the region of low noise heatsinks acoustically. However, when the fan is running at its full default speed, the situation is unbearably loud at almost 70 dBA - it would be incredibly distracting to work next to a PC with the Thermaltake Venus 12 running full tilt.
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 Thermaltake Venus 12 heatsink has a surface roughness of approximately ~32 microinches, which is considered satisfactory. Next, let's see how this heatsink handles the heat compared to a selection of other Athlon64 K8 heatsinks!
