Acoustic Samples: Listen to this Heatsink!

The Alpha Novatech PRE9060M92P heatsink is fairly quiet under power. Its 92mm fan rotates at 3400RPM, which produces just over 51 dBA noise. We have also recorded the sound levels when the fan is running on 6V, and thus at a reduced speed. Alpha do not include a fan speed controller with this heatsink, so this is purely an example of what to expect should you decide to throttle back fan speed yourself. To listen to this heatsink in operation, click on the little headphones icon below and play the sample MP3 files.

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 (~5V) tests reside in each specific heatsink review. ** 'AMD' denotes compatibility with socket 754/939/940 & AM2 processors where applicable. 'Intel' denotes compatibility with socket 775 platform.

With its 92mm ORIX fan spinning at 3400RPM the Alpha Novatech PRE9060M92P heatsink generates 51.5 dBA. By way of comparison, the stock Intel Pentium D heatsink produces about 47.5 dB at its fastest speed. When the ORIX is run with about ~5-6V, fan speed slows and noise levels fall to a whisper quiet 33.6 dBA.

Surface Finish and Flatness

Surface finish is an important factor that we all look for when holding a new heatsink. Flipping a cooler over to see how well the base has been machined is a quick way to judge the attention to detail that was put into making it. The following test involves the use of a Surface Roughness Comparator, which offers a concise cross section common machine surface finishes.

The Alpha Novatech PRE9060M92P heatsink has a surface roughness of approximately 16 microinches, which is considered excellent. Next, let's see how this heatsink handles the heat compared to a selection of other heatsinks!
