Acoustic Samples: Listen to this Heatsink!

TMD fans are a little louder than your average motor-in-the-center vanaxial brushless DC fan. As a result the noise output is a little on the high side, but the pitch is a lot lower. You can listen to this heatsink in operation for yourself by clicking on the little headphones and downloading the 10 second 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.
