Acoustic Samples: Listen to this Heatsink!

The Everflow fan on this heatsink doesn't make that much noise since it is only 60mm size. To hear this heatsink for yourself, click on the small pair of headphones just below and download the MP3 file of the heatsink in operation.

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.

A loudness of just 52.8 dB is pretty decent for a Socket A heatsink. The small 60mm fan that Ajigo use on the MF014021 does not rotate quick enough to generate a lot of high pitched noise.
