Thanks for the article. The metal thing with ridges I received is
definitely a heat sink.

The three peaces for the QuickSilver should be:
* the processor daughter card (riser card, processor module)
* the cooling fan and
* the heatsink.
For the cooling fan you should be able to use the one that is still in your
QuickSilver. I think it is the same for all the processors.
The processor daugther card and the heatsink are a unit when assembled, but
the original apple processor cards are build so that you need to install the
processor first, and then you are able to place the heatsink on it with the
latches engaged.
I recently put a OWC Mercury Extreme 1.4 GHz processor upgrade into my
QS2001
and had to place it on the connectors three times until the QS would boot
correctly. So it might be a fuzzy work to get it done correctly the first
time, since with the original processor you always need to place the
heatsink
on when the processor is in already.
You may try to
* connect the processor daughter card with the mainboard
* place the heatsink *without* thermal compound --> !!! dangerous !!!
* place and connect the fan
THEN try to start the Power Mac.
Check if it starts up correctly like this:
* you just need to see the Apple logo, in case your hard drive is connected
and Mac OS X is installed (check first with your current CPU), or
* by pressing Command-Option-O-F you can enter the Open Firmware command
prompt
Keep the Mac running only as long as you really need to in order to verify
the
CPU is installed correctly and thus it is working in correct order.
Otherwise
you may overheat the CPU --> permanent damage may occur and destroy the
CPU!!!
THEN you place the heatsink the correct way:
* remove the heatsink again
* put thermal compound on the CPUs (refer to the instructions from the
thermal
compound you have bought)
* place the heat sink on it and make sure it is engaged correctly.
YOU'RE DONE!
As for the thermal compound: I use "Arctic Silver III" and its quite good,
kept my CPUs in my MDD Dual-1GHz even cooler than the original compound from
Apple. On the other hand the original compound was a few years old already,
and the Arctic Silver III was new...
You may choose any thermal compound, just make sure it is suitable for the
aluminium heat sink of the QuickSilver.
I hope that helped.
