Acoustic Samples: Listen to this Heatsink!

The waveform image we captured tells the story; the TMD fans are not too loud to use, but they are not silent either. To listen to this heatsink for yourself just click on the headphones and download the MP3 recording.

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.
