Stupid question about installing P4 heatsink

OK,

I realize that this is a really stupid question, but please try to
answer it for me anyway.

Do I need thermal heat sink compound or don't I?

I am installing a 3 GHz Pentium 4 onto an Asus P4C800-E deluxe
motherboard. The processor is already on the board, having been
checked by mbx.com before shipping. The standard Intel heatsink is not
attached yet. There is no heat sink compound in the box, but there is
a square patch of something (???) n the copper surface of the heat
sink/fan where it would touch the processor. This "stuff" is not
sticky or greasy and is a little smaller in size than the processor.
What is this stuff and what do I do with t?

Is there a peel off part that would allow me to stick it onto the P4?
Is is sufficient to place this up against the P4 under the tension
generated by clipping on the sink/fan? Am I better off removing this
stuff and placing some heat sink compound between P4 and sink/fan?

What would you do?

Thanks,

BB
 
AHHH see I want going crazy,,, I had seen the 3.0's coming both ways....you do not need anything for yours....the 1 inch by 1 inch
pad is all you need... careful not to scratch it too much...

It's a thermal pad. Stop touching it! There may be a little bit of
clear tape over it that needs to be removed before installation (or
there may not be). The wax-like thermal pad will be in direct contact
with the CPU die when installed. When you turn the computer on, the CPU
die will get very hot, melt the thermal pad, and all will be well. Do
not jiggle the heat sink around after you've installed it and turned the
system on. Once the thermal pad melts onto the CPU die you do not want
to disrupt this interface. If you disrupt the interface you'll have to
clean the remains of the thermal pad off and go through the whole
process of cleaning the CPU and heat sink of the pad and then applying
thermal grease.

HTH,

What would a purist do, though? Would he rely on the
thermal conductivity of the pad or try for a thinner layer
using thermal "grease"?

the 'warrentyist' would use the 'whatever came with the package'..for reliance.

Not sure if you mean the first install or the second.

For the first, I'm sure either way would be fine.
For the second, scrape off the remains of the pad and either use a brand
new pad or some thermal compound per the Arctic Silver website
instructions.

If you want to do a serious comparison, install MotherBoardMonitor or
similar software so you can monitor the CPU temperature and try it both
ways. Most the folks here would be interested to hear the results.

I meant as a first install. I suspect the "purist" - the guy
who would go to overclocking to get his 'puter as fast as
possible, the guy not satisfied with being "fine" - would
scrape off the pad, clean the die, and then use Arctic Silver
per their instructions. Ahem... that does not necessarily
mean that *I* would do that... :-)

The purist would have the pad off the heatsink before it had ever been
booted a single time. He would know that doing it after the fact,
after the pad had heated/flowed/cooled several times, even very good
cleaning might leave residue from the pad and also make it harder to
remove. Of course a purist would have then lapped the heatsink until
he could shave in it.... and probably would have gotten an OEM CPU
because he had his own ideas about what brand/model HS/fan to cool it
with. A purer purist would have his peltier lapped already<G> and be
considering an exotic thermal compound with carbon bucky balls in it.
A purer purist with money (I've heard they exist) would opt for a
refridgerated case and still use thermal compound as opposed to a pad.

LOL!

And the purest purist would have his monitor program set to trip at .1
degree above room temperature, auto-send email to AMD/Intel customer
service and would spend days trying to find out why it "failed".

I know guys like this. :-)
