Too much thermal paste?

post #1 of 31
Thread Starter 
I had the fan replaced in my MSI laptop a while back and since it was pretty new couldn't find a fan outside of MSI but anyways, the fan/heatsink got pretty dusty so I took the whole thing out to clean and MAN is there a lot of thermal paste on the CPU. I mean, obviously it's too much but is it even worth cleaning off? It's been like this for around 8 months. Just wondering if its bad for those little transistors it's covering

Definetly way too much, I don't think it affects the transistors any. I would assume it insulates them, but no heat gains or shorts. Bottom line nobody should have that much TIM on there chips lol.

The point of TIM is to simply fill in the micro 'cracks' that can exists even on a fully polished chip/cooler. Any more than a very slim application is too much.

I don't think it's a problem. The thermal isn't even covering the whole chip. But then again, it isn't a desktop chip. When I apply TIM to a desktop CPU, I make sure the entire top of the chip is covered in a thin layer of paste. I'm not sure if it's the same with laptops.

The only problem is that now that you've taken the fan and heatsink off, you must get some rubbing alcohol and get the old thermal paste off and put a new coat of it on there. You're not supposed to reuse thermal paste.

Yeah....The guys at MSI must not care about how much paste they use tongue.gif I was just wondering if it's even worth cleaning it all off...haha

You realize that it should only have paste on the die right? I circled the dies and put lines where you should place small amounts of thermal paste. thumb.gif dscn0445n.jpg 1190k .jpg file

Thanks for the replies smile.gif I'll clean it all off and while I'm at it put some AS5 on there. Should I use any sort of special cloth or can I just use toilet paper? lol

I would not use toilet paper b/c it leaves fibers behind.

Use some normal paper towel and alcohol. Then do a once over with a coffee filter and alcohol.
