Hello,

I wanted to clean out some dust from my CPU fan, so I removed the heatsink from my laptop (Dell calls it a processor thermal-cooling assembly). After doing so, I realized that the thermal pad that sits on top of the GPU is now ripped. What are my options as far as repairing or replacing this thermal pad?

My machine is a Dell Inspiron 1525 laptop, and the GPU is integrated into the motherboard. Oddly, the processor has a layer of thermal paste above it but the GPU has this stupid thermal pad.

Any help/suggestions would be greatly appreciated, as I don't have a ton of experience with heatsinks or working with thermal materials. Thanks!

That,s different. There must be a height difference between GPU and CPU. In this video
the guy just slammed it back together. I would be inclined to clean both off and put new paste and pad back on.

In this video the guy replaced the paste but not the pad
Your call

Thank you for your help. If there is a bigger gap between the heat sink and the GPU, would it be possible to just apply a thicker layer of thermal paste instead of replacing the thermal pad?

Otherwise, I was going to order one of these but I don't know if it is what I am looking for.

Geeze, how the heck do you "refurbish" a thermal pad. <_< I would think a local computer repair guy would give you a piece if he had it, but yeah its the right one for your machine.

Paste is meant to fill in tiny irregularities in the top of the processor and bottom of the heatsink. If it is applied to thick, you risk the chance that the heat from the chip will cause the paste to spread out and drop, losing its optimum cooling ability. Sometimes making it worse than having none.

I'd say the pad was put there for a reason and I would stick with it.
