The Quietude II betrays its name with a fair degree of noise from the fan. If you are looking to build a quiet computer you may want to avoid this particular heatsink, though it does perform well. The thermally controlled fan starts off moderately quiet, but as soon as the temperatures begin to rise it hits the high notes. To listen to this heatsink for yourself in operation, be sure to click on the little headphones icon below and download the Acoustic Sample MP3 file.

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. Measurements are made on the dB (A) scale.

The Spire Quietude II clocks in at 53.2 dBA which places it about middle in terms of the noise and the other reference coolers. This sound measurement was taken with the heatsink running at room temperature. Because the SP411C5 uses a thermally reactive fan, it does produce more noise when the heatsink is at elevated temperatures.
