Can I replace a thermal pad with paste?

post #1 of 15
Thread Starter 
I've got a laptop that, and the CPU was overheating, so I opened it up and pulled off the heatsink to apply some new stuff.

However, I found that the heatsink was also attached to the chipset/gpu and they both had thermal pads, which I pulled off/broke.

This one I'm worried about.



Can I just take it off and put paste on it?

Image fixed.

Image fixed again. Screw imageshack.

I can't say for certain, but one thing to consider...they might have thermal pads on them due to fitment reasons. I say that would be a good thing to check first. If the heatsinks would touch, I would think paste would be fine, but once again, I'm not completely certain on that.

Crap. You're right. The section of the heatsink is raised.

What to do...

I have ran into this before, and i just cleaned both surfaces, and then applied a large grain of rice in the middle of the CPU. Then put the HSF back on and it was fine.
When you put it back on, see to make sure that no paste gets out on to the board, if not you should be fine.
Start up the system and monitor the temps closely.
