Acoustic Samples: Listen to this Heatsink!

Because of the small 15mm thick fan the 5T235 is a fairly quiet heatsink to use. The fan rotates at about 5000RPM but draws just 0.24A. Without a lot of bearing noises, a heatsink of this nature is great for standard systems because it is not especially noisy - but keep in mind it is not silent either. To listen to this heatsink for yourself, simply click on the little pair of headphones and download the 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.

Below 55 dB is usually pretty good, and the 5T235 manages that with a few decibel to spare. The heatsink is not entirely silent, but it operates at a comfortable level of noise which is a bonus in a way.
