Aopen ACP4LC Pentium 4 Heatsink Review
The
Aopen ACP4LC is a tall heatsinks, standing a whopping 98mm high, 55mm of which is taken up by the fan
and adaptor. While the Aopen ACP4LC Pentium 4 heatsink isn't
particularly revolutionary in design, or materials, it makes up for
that with a bit of brawn, and an economical sticker price.
On top
of that, the Aopen's fan adaptor allows an 80mm Nidec fan to
mount to the 70mm heatsink frame. The point of this, is of course to reduce
the noise created by the fan by using a larger and slower rotating
impeller.
Combined, these two
traits allow for a fan which moves more air slower than a smaller fan, but
moves the same overall amount of air to keep the heatsink nice and
cool.

In our
time we've seen many methods of attaching copper base plates to aluminum heatsinks. Some manufacturers plate
the aluminum with nickel and then use that as a basis to solder
on the copper. Other have used screws, white silicon compound, bolts and a bit of
force to manually attach a copper base plate to the bottom of an extruded aluminum
heatsink.
Since the copper
portion of the Aopen ACP4LC is what actually comes in contact with the
processor. it is very important that the rest of the heatsink (specifically the
fins) make excellent contact with the copper.
If the heat energy being absorbed by the copper isn't actually
being transferred to the aluminum portion of the heatsink effectively, then what's the
point after all? In the case of this heatsink, it looks as though
the aluminum was soldered to the copper.
