Don't forget to clean that heatsink!

I recently noticed that my Intel P3 500e O/C to 700 (fcpga, 1.65V) was getting a little hotter than I liked. Until an hour ago, ASUS probe was reporting around 55-60deg C under load, and around 45 idle.

Any way, I decided it might be a good idea to take out the CPU to see how it was doing, so to speak. Well - the heatsink was COVERED in a thick layer of dust. If you think about it, this dust would be liable to insulate heat - not a good thing at all when you want a nice cool CPU. So, I blew/wiped off all the dust, put the CPU back in and low-and-behold, ASUS probe was reporting 45Deg C under load and around 33 when idle! I've since re-applied some generic thermal paste which has helped even more (minus a few degrees). But the dust thing is something to look out for.

Just thought I'd share that with ya, as it might not be something one normally thinks of :)

BTW, this was with a stock heatsink. I'm getting sent (for free :p) a FOP 32 in a few days which I'll be slapping on. Hopefully that will decrease temps even more.

This tip should win the Good Housekeeping Seal of Approval. ;)

Ok, here we go you not gonna belive this!
I cleaned out the heatsink (Pal6035) using hot water and dryed it with a hairdryer, (hot hot hot....that heatsink gets soo hot touching the water or getting dryed with hairdryer) then i blew the dust outa my geforce2 heatsink, and then i blew all the dust outa the case and dusted the cpu fan (Ystech 27cfm).

Before:
46c idle
50c loaded

After:
42c idle
44c loaded

Im impressed

heheh, not bad. My heatsink has literally been inside of my case for almost a year, so the dust was very thickly spread.

Exactly why I have foam filters on ALL intake fans (2 - 80mm, w/ 1 - 80mm exhaust in the PS) and taped up all cracks and crevices around the entire case. My old IBM-XT [circa 1984] actually stopped turning on {every 3 months, or so} due to the dust that was picked up at my auto repair shop business; I just got in the habit of 'field-stripping' that box every 2 months for over 7 years, until I retired it for a 'commercial-variety' 386DX33 with very effective filters.

Just installed the FOP 32.

Temps are now:

Idle: 26 Degrees C
Load: 36 Degrees C

Not a bad little heatsink :)
