Acoustic Samples: Listen to this Heatsink!

Noise with this heatsink is really kept to a minimum because of the small fan used here. 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.

When we took a sound level measurement with the Omega HHSL1 sound meter we found that the Eumax EU01 produced about 55.4 dB worth of noise. That means this cooler may be drowned out by the power supply or video card cooler.
