Acoustic Samples: Listen to this Heatsink!

The Gigabyte 3D Rocket Cooler-Pro heatsink is moderately quiet, given that squirrel cage fans are not normally known to be very quiet when operating at high RPMs. Since the fan in the PCU22-VG runs at between 2500-4000RPM, noise levels fluctuate between 43.8 dBA and 56.7 dBA. To listen to this heatsink in operation, be sure to click on the little headphones icon below and play the sample MP3 file.

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.com 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. 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.

In this particular reference list, the Gigabyte 3D Rocket Cooler-Pro heatsink is fairly average for noise, with a maximum measured sound output of 56.7dBA. With the fan speed dialed all the way down, the situation is much quieter at 43.8 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 Gigabyte 3D Rocket Cooler-Pro PCU22-VG heatsink has a surface roughness of approximately 16 microinches, which is considered satisfactory. Next, let's see how this heatsink handles the heat compared to a selection of other heatsinks!
