Acoustic Samples: Listen to this
Heatsink!
The sound
levels that this heatsink produces are not that high, and in fact in the server
environment they are probably muted out by other case fans or SCSI drives. Still
if you are looking for something to cool a small form factor P4 cube system we
have taken the liberty of recording the actual heatsink sounds.To hear what this heatsink actually sounds like, just
click on the little pair of headphones and listen to this heatsink for
yourself.

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.

AT 55.1
dB the Dynatron DC1206BMV is rather loud on our small list of socket 478
heatsinks. The small fan would seem to one that would make less noise than the
others, but perhaps the close proximity to the fins is causing a lot of
turbulence amongst the exhaust air. In any case, the DC1206BMV is louder than
the standard Intel retail heatsink.
