CPU ... without paste?
Computer CPUs are supposed to have some sort of paste between it and the heatsink/fan, right?

Umm, for some reason the CPU in my laptop doesn't have any on it. This is leading me to wonder if that's how it is supposed to do, or something cleaned the thing off? It does tend to get a bit hot and I think the video card has a tendency to freeze up when it gets too hot, but should I order some of that paste-y stuff?? (Oh, I do not look forward to taking it apart a... waiiiit, I probably wouldn't have to do everything I did this time again, now that I know what I'm doing. heh)

Edit to update: I took the fan off the CPU again to make sure it didn't have a thermal pad (or whatever) on it instead, and it doesn't. I guess they figured they made a perfect CPU (hah!) so it wouldn't need any thermal paste. It has like... a smudge of ... something ... on a few of areas, but hardly enough to be adequate. Definitely need to put some on it.

That paste is important for extending the life of the processor by helping it dissipate heat to the heatsink. It's very cheap (like $2 for a tube with enough for multiple uses) and you should be able to find it at a computer store.

Mike sez:

Either a paste or a tape. Look for something that looks like a little grey or black tape. that's aluminium-embedded tape. If not, you can go to vitually any computer parts store and get a tube of thermal paste on the cheap.

Laptop CPUs run at a lower voltage than desktop CPUs. They also have temperature sensors which throttle the CPU down if it begins to run too hot. I personally wouldn't worry about thermal transfer compound.

You can pop the heatsink off any P4 class processor and it will slow to a crawl, but won't fry itself. I actually experienced something similar recently when I accidently pushed a cable down into the CPU fan. For all intents and purposes, I had no fan at all during that period. The CPU was running at the wrong speed at startup and refused to reset to the right speed, which led me to check the hardware.

I should note I have an Althon64 that is almost two years old. Intel chips added thermal protection even before AMD.
