Touching
the tiny Coppermine core still has me in awe of the 0.18u microscopic design
process. I can only imagine what resolution on the engineer's huge monitors
that must be required. My sample was manufactured in Malaysia in the 13th
week of 2000. Click on each pic for a 200-400 dpi hi-res image. For best viewing,
adjust your monitor to 1280x1024@24bit color or greater.

The GlobalWin
FKP-32
The heatsink
fan package is the hot new GlobalWin FKP-32. This monster is the biggest setup
for a FC-PGA I've ever seen! It's heatsink is a very efficient and smart design.
Contacting the processor itself is the smaller portion (area wise) and looking
closely, you'll spot the slight indent (click on HS & Fan 1) that steadies
the heatsink against the raised portion of the ZIF socket. A few millimeters
higher up, the heatsink spreads out on two sides to increase the surface area
without blocking CPU space and capacitors on the motherboard. The engineers
even figured out a way to keep the height to the absolute minimum by way of
eliminating the screws that waste 3 mm on the top of the fan. The fan is the
same unit used in the less expensive CPM-32 and is rated at 26 CFM at 12 volts.
And you hear every foot of it. Clips are ingeniously used to secure that fan
to the heatsink--nice touch.

ZIF (zero
insertion force) sockets are great, they have eliminated the nearly 100 lbs
of force required to insert older socketed processors. Anybody notice that
the force and dexterity required to push and hook the newer socket-370 clips
have taken the place of the old processors? Pushing down is one thing, but
pushing down while angling the clip in a tight space can be hard on the thumb.
While I've never actually measured the force, I'd bet that 30-40 lbs are required
to install the heavy duty models, similar to the ones that come in GlobalWin
packages. After a few grunts, I'm dubbing these quick-clips as "Jesus"
clips for obvious reasons.
The FKP-32
package comes with a small packet of high performance thermal grease. Two
grams may not seem like much, but when you have approximately one square centimeter
to lightly cover, that packet is overkill. It could probably be good for 50
or so Coppermines. Needless to say, put the grease on the processor, not the
heatsink. That way, when you force the Jesus clip on...for the third or fourth
time, you don't get grease all over your fingers.
