Spire BFA07B2 Copper Core Heatsink Review
Spire BFA07B2 Copper Core Heatsink Review
  83%   
Abstract: Based on an older design which did not feature a copper insert, the BFA07B2 can almost be considered a second generation heatsink.

Acoustic Samples: Listen to this Heatsink!

Because of the small 15mm thick fan the BFA07B2 is fairly average on the noise front. The fan rotates at about 4200RPM but draws just 0.24A. 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.

True enough, as we expected the Spire BFA07B2 MicroFlow II weighs in acoustically at just 50.6 dB - which is pretty good. The heatsink is not entirely silent, but it operates at a comfortable level of noise which is a bonus.
