 When
it comes to heatsinks, a minor change in a design can mean a
couple degree differences in performance. The Hedgehog
heatsink steps in with a major change in design.
Rather
than using the standard aluminum alloy, they opted to try
something different, all copper. The question goes through a
lot of people’s minds. Is copper better than aluminum? The
answer to that is both, yes and no. Copper is the immediate
superior material for heat conduction compared to aluminum
from other metal surfaces, but its heat transfer to air is
not as good as aluminum. That is why you will see a copper
base surrounded by aluminum fins for some of the newer Alpha
heatsinks.
The
all copper Hedgehog heatsink does have a weapon to combat
the slow metal to air transfer by placing larger, louder and
powerful fan on top of them. Not all Hedgehog heatsink
models have the larger fan though. The 238-M model comes
with a Y.S. Tech 60x60x25mm 5400-RPM fan. The 238-S comes
with a 60x60x10.3mm 4200-RPM fan. The 238-M is the best
choice for this type of metal heatsink.
Installation
The
Hedgehog
238-M is designed for both Socket 370 and Socket A
CPUs. I did notice that the heatsink did not come completely
flat on the base. With some 600 and 1000 grit sandpaper I
got the base to a mirror like shine. Putting together the
cooler was very similar to that of the Alpha. The
recommended placement of the fan is to have it so the air is
blowing away from the CPU. On tests done with the Alpha, I
have found that air blowing away from a socket type CPU does
help to decrease the temp of the CPU. If you do plan on
having the fan facing towards the CPU, then it is
recommended that the shroud be taken off.
The
test system I used was a Pentium III 650 on an MSI i815E Pro
motherboard and the same Pentium III 650 on an Asus P3V4X
with an IWill Slocket II. I had no problems installing the
unit on the MSI motherboard. When it came to the Asus board
and the IWill Slocket, I had a little trouble getting the
clip so that it wasn't pushing against a couple capacitors.
With a little adjustment I was able to overcome this
trouble.
