Acoustic Samples: Listen to this Heatsink!

With the 15x70x70mm fan on the Igloo 4300 it is a little bit on the loud side. Stock Intel heatsinks are always a lot quieter. To hear the heatsink in operation for yourself, click on the little headphones below and download the MP3 file.

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.

We measured the Igloo 4300 with our sound meter under real world conditions and it produced just about 57 dB of noise. The stock Intel heatsink on the other hand generally produces less than 50 dB of noise.
