Dynatron DC1U-B02 1U Copper Heatsink Review
Dynatron DC1U-B02 1U Copper Heatsink Review
  62%   
Abstract: As there is generally no more than about 30mm of height for the entire cooling package, fans will obviously take up precious real estate. For Socket 478 Intel processors.

Acoustic Samples: Listen to this Heatsink!

The amount of noise that the DC1U-B02 creates is suprising given the 50mm squirrel cage fan. The heatsink is very loud for its size, but since we are looking at 1U server applications this is sort of a moot point. To listen to this heatsink for yourself in operation, be sure to click on the little headphones icon below and download the Acoustic Sample 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. Measurements are made on the dB (A) scale.
