What is wrong with my Prescott?

A few months ago I started receiving poor processor performance immediately after rebuilding my computer in mATX form factor. I downloaded throttlewatch and it was showing signs of 20-50% throttle, so I ordered an Alpha HS/Fan combo to replace the 2.4 P4 stock cooler that was currently on my p4. The Alpha I got was supposedly one of the best socket 478 coolers out there, and the fan is very loud running at over 4000rpm's. This fixed my throttle problem for the most part, however I opened up throttlewatch during load to find my computer still throttling a small amount 1-10% sporadically during intensive loading. I've got an two new Core2Duo machines (e6300/e6600) and I'm selling this build to a member of my friends family, who doesn't necessarily need ever little bit of performance out of it, but I didn't think she'd enjoy the sounds my Alpha fan makes so I tried seeing if I could underclock and use just a heatsink on my P4.

I underclock my P4 to 185mhz*17 which is about 3.17 and then turn off the fan. I boot up. Cpu jumps from 31 Celsius to 83, and i immediately shut it off. I touched the heatsink to make sure it had a good connection with the processor and was even cooling it and it was blazing hot, i mean you could feel the heat radiating from this thing.

I really want to remove the fan, but I don't want to underclock it to a 1.7 to do it. Anyone have any suggestions or similiar experiences?

These temps are idle for the most part, and my fan is blowing air on the proc instead of sucking it out.
 
It'd probably be better to just buy a "quiet" HSF than trying to passively cool it.. And dropping 300MHz probably won't lower your temperature a much anyways. After all, it is a prescott, notorious for being incredibly hot.
 
Are you using artic silver or something similar when replacing the heatsinks?

I just did a trade with a friend and he got my 1.8ghz@2.2ghz Northwood and I got his 2.8ghz Prescott. Prescott runs in the low 50's at idle and Northwood runs around 30 at idle even overclocked. Prescott is a POS as I doubt I can overclock it on air with those temps.
 
Try undervolting it maybe with minimal underclocking.
And get arctic silver or ceramique standart thermal paste is POS.
And maybe try Arctic freezer those are dirt cheap and offer good not too loud cooling. Since probably scythe ninja + good 120mm fan would cost too much for what it's worth :D
 
Standard thermal paste will do just fine. Temperature difference between arctic silver and strawberry jelly is 2-3c (applied corectly)..
 
That's 2-3 C you get for almost free i payed 6-7 $ for my small tube of ceramique and it already lasted for 5 CPUs and more than half is still there.

I ordered this stuff for my two new c2d builds, anyone have any experience with it?


Only review there said it cooled his cpu over 8c better than A.S.5

Bad stuff, don't use it:

It reacts violently to aluminum.. The top of your C2D is an aluminum heatspreader... (edit: now that I think about it, it might be nickle plated copper.. but even still)

Thier own website: http://www.coollaboratory.com/en/ says: "Please do not use any aluminium coolers!"

And even if it is a tiny bit better (which I doubt) it ain't worth the risks.

I have a ninja scythe which is copper, and i really doubt the top of my c2d is aluminum.
