Acoustic Samples: Listen to this Heatsink!

This is a very quiet heatsink and even though overclockers may find the subsequent thermal performance not up to their lofty standards regular users will be more than appreciative. Computer noise has been a major issue with us for the last year or so and we are glad to see that manufacturers are finally coming around in the mainstream markets and offering low noise cooling solutions.

To listen to this heatsink for yourself, simply click on the little pair of headphones and download the MP3 recording.

Sound Level Measurements:

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 Decibel readings with a sound level meter. These results may be higher than the manufacturer's listed specs, but then again these are real world measurements.

Aside from the 92mm Zalman fans on the lowest of speed settings the Coolermaster HHC-L61 is one of the quietest heatsinks we have measured to date. The thriving low-noise cooling market is being met with some really good products certainly. With a measured noise level under real world conditions of 42.2 dB the HHC-L61 is very quiet. Now, let's now see how the heatsink performs in our synthetic thermal tests...
