Yet another ...............FREE P4 Cooling tip.

Please don't flame me again. 🙁 I am just sharing what I have found.

Last night, I just learn that P4 use heat spreader that metal surface is NOT the core.
(fine...laugh all you want, I just found that out) 🙁

Anyway, I also heard that remove the heat spreader able to drop the temp down for few degree.

Then it hit me.....I saw there is a little hole on the heat spreader.
If I am a ant, I can reach the core from that hole!!!!!!!!
In other word, heat can also escape out from that tiny hole!!!!!!!!!!!!

So, I took out my drill, secure the 7/64" drill bit. Line up the HS w/ that hole, make a mark w/ HS paste!
Then I drill a hole through the HS!!!!!!!

Resurface HS/ put the paste and install it............................
OUCH!!!!! 2 degree drop on full load!!!!!!!!!!!! (UT2003 again)
 
Nice tip TimeKeeper, I'm not exactly sure where/what you're drilling tho, can you explain a bit more? You drilled a hole all the way thru your heatsink? Is that right?

The cool thing about your tip is you don't have to worry about selling your chip without a heatspreader....🙂
 
yea id imagine hes drilling thru the heatsink into open air.
open air that can get into that hole and help cool the core 😉 (if only just a little)

the p4 IHS will easily leave a mark on the HS for drilling....
 
Cool....that's a pretty good idea, esp. if you don't want to bother with the heatspreader...🙂

Just wondering....what if you drilled a hole on the opposite corner of the heatspreader, then drilled the corresponding holes in the heatsink...giving you a flow of air under the heatspreader....hmmm....😛
 
there is already a small "gap" under part of the IHS to exit air.

youd have to remove the IHS to drill it ~ may as well leave it off right?
 
your tests aren't conclusive at all, they were taken on different days.. the temperature in your house could have changed in that time period and caused different cpu temperatures, also some maps in ut2k3 are more cpu intensive than others, which could have caused the small difference😛

yes, but obviously his temps wer higher yesterday, while ambient temp was lower!!!! that proves a lot!!! And unless he is dumb, he was playing the same maps and all!!

VERY TRUE, Anything possible. Obviously, it is NOT conclusive. But I am sure it wouldn't hurt right? Not exactly P4 setup need that much extra cooling. (otherwise, I wouldn't undervolt my stock Fan speed) 🙂

hmmm............okay I am dumb. 🙁
The online DD only got around 5 different maps, although I got my ass kick all the time by those experts!

When testing CPU temps (not stability) I use CPUBurn. It will heat up your CPU quickly. It gets it hotter than Prime95 or playing a 3D game such as UT. The results are consistent. And yes, temp testing needs to be in a controlled environment. 1C room temp change = 1C system temp change, 1C CPU temp change. My CPU idle temp is 2 - 3C cooler in the AM than in the afternoon this time of year.
