spilt over thermal compound

Is there a quicker way to clean this besides alcohol + q-tips?

Bought this old laptop (CQ60-215dx) for $75 from a friend. He said he thought it just had viruses that causes it to randomly shut off, but after booting it up it quickly got hot... ~88C. The thermal paste is spilt over and of course barely touching the heatsink.



 
A microfiber cloth or stiff paper towels and acetone, but be careful.

Also, a small razor blade will help, if it is gummy.

If it is thin, I would use paper towels or napkins to mop it up, and then more carefully clean the actual contact surfaces.

That said, it looks to me like it wasn't mounted well. Look at how much TIM is still on the heatsink on one side, but not the other. Even thick OEM gunk aught to get down to an even paper-thin layer.

After cleaning and reapplying, you may want to make sure that it makes good, flat contact, and that the heatpipe+fan part, or anything else around, isn't bending it away from the CPU.
 
Thanks for the advice, but I think Im giving up on the gunk around the chip. Its just taking too long for any kind of results. The chip itself and the heatsink is clean. I just hope that gunk won't cause it to short.
 
By any chance could I replace that blue thermal pad with just compound? Or do I have to find some copper to replace it with first?

Thanks

You can as long as the heatsink sits flat and level on both chips at the same time.

They make thermal compound remover. Its like $6 for a bottle that should last you forever. Just squirt it on and after about 5 mins it knocks that stuff right off.
 
Ok because the part of the heat sink that sits on the gpu isn't copper. And I don't know of any places that sell the small copper shims.
 
use some goo gone.

that kind of thermal 'pad' is hard and gummy. you will likely have to replace the pad, i would try to find one online. the tricky part is that in different notebooks, they have varying thickness.

i doubt you can roll without one, the heatsink probably is too 'tall' because it assumes a pad will be in place between the die of the chip and the heatsink.
 
Shoot! I just threw some ceramique on it. CPU idles around ~44C, Load ~62C. GPU is around 10-15C higher.

Thanks for the link... I'll look for some like those in the states.
