Arctic Cooling have developed what is perhaps the
oddest looking fan we've seen in a long time... The Copper Silent 2 is AC's
heatsink for the socket A platform, and what it lacks in sex appeal it makes up
for in acoustic stealth. After all this is a very quiet heatsink, clocking in at
barely 38 dB - remarkable considering the many loud heatsinks out there for
AMD processors. The trick
really is to make a heatsink thermally efficient without sacrificing acoustics.
Noise levels are important, but if the heatsink doesn't cool very well then what
use is it?
Arctic Cooling have created their
heatsink with a rather unique spin on traditional fan design. The motor is
suspended above the fan, and the impeller blades are positioned
almost touching the tips of the aluminum fins.
| Four small foam rubber pads are placed so that
they contact the
heatsink directly and in an effort to prevent vibrations or rattling which could cause
cooler looks odd, and somewhat like an industrial fan used in ventilation
situations. The inverted fan spins at 2200 RPM, blowing air down into the
aluminum fins, and is reportedly designed this way to produce less of
if Arctic Cooling's Copper Silent 2 wasn't already unique enough, four foam
rubber pads separate the plastic fan shroud assembly from the aluminum heatsink
in an effort to further reduce potential areas of vibration.
Whether or not these little foam rubber pads are
thick enough to actually absorb vibrations from an unbalanced fan motor is up
for debate though.
On the base of the Copper Silent 2 is a big slab of copper, copper which has
been soldered to the aluminum heatsink in an effort to further improve the
overall thermal effectiveness of the cooler.
