Zalman CNPS5700D-Cu Ducted P4 Heatsink Review
  88%   
Abstract: When the Zalman CNPS5700D-Cu arrived I have to admit there was a bit of a "whoa" factor to contend with.

Acoustic Samples: Listen to this Heatsink!

Running under normal power levels the CNPS5700D is a bit louder than other Zalman heatsinks, and this is mainly due to the fan duct which creates a bit of air turbulence. The heatsink under quiet mode with the fan mate 1 is pretty quiet indeed. To listen to this heatsink under full power for yourself, click on the little headphones below and download the MP3 file.

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.

Zalman CNPS6500-AlCu 47.4/28.9 dB quiet

Cho-Liang CL-CB0094-1A 49.8 dB
Cho-Liang CL-CB00881 50.2 dB
Taisol CEP426151A 50.7 dB
Vantec CCK-7025 51.4 dB
ChoLiang CB0307Z17 52.9 dB
Dynatron DC1207BMW 53.0 dB
Zalman CNPS5700D-Cu 53.8 dB
Globalwin VA476 54.2 dB
Dynatron DC1206BMV 55.1 dB
Glacialtech Igloo 3300 55.4 dB
ChoLiang CB0309Z17 55.7 dB
AVC 117140 56.1 dB
NengTyi NW6700 58.0 dB
Coolermaster IHC-H71 64.4 dB louder

At 53.8 dB the CNPS5700D is running at full power. The sound is mostly coming from the air moving about in the air duct. We tried a few trick to quiet this sound down by splitting the duct into two parts but this really only succeeded in limiting the amount air being exhausted.
