Acoustic Samples: Listen to this Heatsink!

The AVC fan is moderate on the noise scale - coming in at just over 50 dB in our tests. You can listen to this heatsink in operation for yourself by clicking on the headphones and playing the MP3 recording.

Sound Level Measurements:

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 Decibel readings with a sound level meter. These results may be higher than the manufacturer's listed specs, but then again these are real world measurements.

Sibak AC06725TH 62.4 dB
Dynatron DY1206BH-625 63.3 dB
Dynatron DC1206BMP 65.1 dB louder

I would say that a 51 dB measurement in to today's computers would be pretty mid-ground, as it is with the list above. With the case closed up, the only real sounds you might hear is whooshing air - which is what puts the AVC 112C81 at this noise level in the first place.
