Title: one good reason to use quality thermal paste.

Well I will let the photos speak for them selves.

That possessor was glued to the heatsink, with some alcohol and very slight prying from a butter knife, I was able to get it unstuck. Let this be a warning to you. Don't buy the cheap crap and reapply once and a while!

Wow. Weird timing Knight. I picked up a computer yesterday... same thing. I don't think it's glued on but rather the stock OEM (probably wax-based) thermal compound just dries and cakes up. That's probably one of the reasons why in 775's the compression mounting that holds the CPU in place actually covers the outer edge so this wouldn't happen anymore. I haven't been around computers long enough to know but the computer I got looked like it hadn't ever been worked on which would mean that the thermal compound had 5-6 years + of use on it, maybe AS5 dries up a bit after that amount of time and heat?

Also, gj on the butterknife method. I just used a piece of metal without any alcohol :) Skrewup, it's completely safe if you know what you're doing.

Np, that cpu was from an OEM hp that had never been worked on, Celeron D. You are probably right about the wax, I don't think AS5 drys up like that. I do know it cures, but I have never heard of it "gluing" a cpu like that. I use AS ceramique and have never had a problem with it. Has similar thermal property's as AS5 but is non-conductive. It cures and can be a bit of a problem to get the heatsink off if you use to much. And I got 3, 22cc tubes for 15 bucks at Fries.

I read somewhere that Intel or OEM's or something add wax to the thermal compound to help carry it to the crevices. I think I actually have had that problem with AS5 just from using a pinch too much and a super tight seal (I hand compress the heatsink against the motherboard after mounting). However, I haven't seen dry AS5.

GTFO with your non-conductive-ness. Noobs worry about that :) AS5 isn't conductive per-se, but it's components CAN make an electrical joint. Even if you got some on a SMD resistor or something, you would have to join it with another connection that would damage the component and hope that the AS5 makes an electrical connection in order to damage something.

Call me a noob if you wish, but I would rather err on the side of caution. Plus it was dirt cheap and is high quality.

=\ On the newer Intel chips you apply it on the IHS and there's nothing close to short out. On northbridges or southbridges, especially Nvidia ones, there can be some SMD's but if you know enough to take a heatsink off, you should be able to see any stray thermal compound and wipe it up. Also, for the chips, there's usually a foam pad to protect the SMD's. This is all IF you're messy with applying it. Not trying to be an ass, really.

I only work on one newer intel cpu :) And I don't think you are an ass I understand :D

:) Newer, to me, = P4 and up. I'm not too familiar with the AMD ones, I know there's single-core Athlons that don't have an IHS and have the SMD resistors on them.
