Acoustic Samples: Listen to this Heatsink!

The Zalman Fatal1ty FS-C77 heatsink runs at one fan speed only, 2400RPM, which creates about 56 dBA noise. 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.

When the 120mm fan moves at 2400RPM the Zalman Fatal1ty FS-C77 heatsink produces a somewhat loud 56.5 dBA noise. This heatsink is built with gamers in mind, so we have to assume that this noise level wil go unnoticed as headphones or 7.1-channel audio systems crack out the bang's of high intensity gaming. H'mmm... kinna makes you crave a little RTCW or Quake 4 action all of sudden doesn't it? ;-)

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 Zalman Fatal1ty FS-C77 heatsink has a surface roughness of approximately 8 microinches, which is considered very good. Next, let's see how this heatsink handles the heat compared to a selection of other heatsinks!
