Sound Level Measurements: Which Heatsink is Quietest?

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 noise level measurements with a sound level meter.

FrostyTech Heatsink Noise Level Measurements Noise level Decibel measurements of each heatsinks' fan in operation are taken with the aid of a sound level meter and sound isolating enclosure. The values may be higher than the mfgr's listed specs, but are directly comparable to one another. Measurements are made on the dB (A) scale, lower values are best. Information on Frostytech's test methodology is available here.

			noise level (dba)
*unless noted, for reference heatsinks with variable-speed fans only the 'high speed' (12V) fan noise measurement is included in the comparison sheet; more detailed results for the low fan speed (lowest RPM or ~5V) tests reside in each specific heatsink review. ** 'AMD' denotes compatibility with AMD processors and 'Intel' denotes compatibility with Intel processors.

Noise output from the 77mm PWM fan rotating at 5500RPM is a very loud, 68.4 dBA. Frostytech's synthetic thermal test results for the 200W Intel thermal test platform are next.
