Acoustic Samples: Listen to this Heatsink!

Because of the fan speed control we are offering you the opportunity to listen to the Coolermaster ASBV73U1 while it is running at the lowest (virtually silent) speed, and the fastest and loudest setting. To listen to this heatsink for yourself in operation, be sure to click on the little headphones icon below and download the Acoustic Sample MP3 file.

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. Measurements are made on the dB (A) scale.

It is not surprising that the Coolermaster Aero1 ranges from nearly silent to ear splitting. The fan is loud, and draws a lot of current when the RPM is dialed all the way up.
