ATTECH (Advanced Thermal Technologies) is a relatively
new company (formed in December 1998). They specialize in producing
copper heatsink's for IC packages and CPU's.
Today we're looking at their CM25 Socket-370 Cooler
which is comprised of a 15mm dense-finned copper heatsink and a
low-profile fan. The main pull behind this cooler is it's very compact
nature making it useful for tight operation such as flexATX/microATX or
book sized PC's.
Here are the complete specs of the CM25, as well as
those of Thermaltake's Golden Orb, for comparison purposes:

Comparing the specs, the first thing you'll probably
notice is the poor fan on the C M25.
Being that thin comes at a price: Lower air movement. Fortunately,
the CoolerGuys purchased the heatsinks alone and have outfitted them
with more powerful fans.
Even if the CoolerGuys fan is not good enough, the
heatsink is versatile enough so that you can add almost any fan you like,
giving it even more cooling potential. As you can see from the
picture on the left, the fins are extremely dense and the entire thing
is made out of Copper which is one of the best conductors of heat and
electricity and doesn't cost a whole lot to manufacture.
The CM25 uses one of those standard spring like clamps
in which you hook one side in and push down really hard on the other
side and somehow try to get it under the other hook. When you're
dealing with a Slocket, it's not so bad, because you have a lot more
room, but when you're working with a socket on the motherboard itself
and the motherboard being mounted inside the case, it becomes extremely
difficult and frustrating. Thermaltake tried to remedy the
situation by making a different type of mounting device in which you
hook on both sides without any pressure, then you turn the heatsink and
it's supposed to lock itself that way. It's a good idea, but damn
scary because of the pressure required to turn it fully.
So, after nearly ripping the skin of my fingers, I have
come to the conclusion that I hate Socketed CPU's and heatsinks and I
wish they had stuck with the Slot format, which I oh so dearly
miss!
Let's get on with the tests, shall we?
