Acoustic Samples: Listen to this Heatsink!

The Asus Triton 79 Amazing heatsink uses a single 120mm PWM fan rotating at 1300RPM, however since it's a PWM fan the speed can be decreased by the motherboard BIOS as desired. The heatsink is fairly quiet while running which is always good 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 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 120mm PWM fan going at a moderate 1300RPM, the Asus Triton 79 Amazing heatsink doesn't produce much more than 44.3 dBA noise. Next up Frostytech will compare this heatsink against the best AMD heatsinks available.
