Abstract: In this configuration it is the absolute loudest, most annoying, and hazardous-to-fingers heatsink we have ever tested.

Acoustic Samples: Listen to this Heatsink!

The waveform image here is basically overloaded because we didn't turn down the volume enough for this test. The acoustic sample gives you a first hand taste of just how loud this combination is, and makes that waveform image seem a little more accurate than it really is. If we had the recorder set at the right volume level it just wouldn't have cut the top/bottom of the image below - other than that, the acoustic sample is pretty true to form To hear just how loud this heatsink and fan combo are, please click on the headphones and listen to 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.

FrostyTech Sound Level Results
- Manufacturer Model Noise Level Scale
Verax P16 35.3 dB quiet
Zalman CNPS6500B-AlCu 47.4/28.9 dB
Intel Socket 478 42.5 dB
Cho-Liang CL-CB0094-1A 49.8 dB
Cho-Liang CL-CB00881 50.2 dB
Vantec VP4C7040 55.6 dB
Taisol CEP426151A 50.7 dB
ChoLiang CB0307Z17 52.9 dB
Dynatron DC1207BMW 53.0 dB
Globalwin VA476 54.2 dB
Dynatron DC1206BMV 55.1 dB
ChoLiang CB0309Z17 55.7 dB
AVC 117140 56.1 dB
NengTyi NW6700 58.0 dB
Coolermaster IHC-H71 64.4 dB
Thermalright AX-478 66.5 dB louder

The Thermalright AX-478 with the 38mm Delta fan breaks the previous noise level record for the socket 478 platform and jumps all the way up to about 66 dB. That is very loud for a heatsink, and is one of the reasons why this combo won't suite everyone's tastes.
