Mobility 5870 too HOT!? - Page 2

post #11 of 15
Never spread thermal paste. It never works. Ever. Maybe if you did it perfectly. But I've found results are always terrible. Even if it did work, it's unnecessary because the pressure of the heatsink against the IHS spreads it for you.

Just put a tiny, BB sized dot in the center of the die. That's all you need for a GPU.

The factory had definitely spread the paste on very thickly, it was caked up and overflowed all around the sides of the die. Seeing that, I thought for sure this repaste would fix the problem.

I spread it thinly across the entirety of the die, seemed good. I was using old thermal paste however, because the new stuff my buddy had was metal-based and I wanted something non-conductive. So it was an old bottle of this stuff: http://www.newegg.com/Product/Produc...scrollFullInfo

Needless to say, very disheartened by this result. I guess it could be bad paste...that or maybe the heatsink isn't tight enough to make really good contact?

I ordered a tube of MX-4 off Newegg and I'll try again, hopefully this weekend. At least I'm warrantied, so RMA is still available to me if I don't find any benefit from another repaste.

Anyone have advice for me going into this next attempt?
Never used the TIM in link above to tell how it performs. Wait for the MX-4 and see it will lower the temperature. If not, just RMA. Something is not right with the card operating temperature.

I prefer to spread it thinly with MX-3/MX-4. It is true for some silicone base TIMs or some other types will spread better with a small blob in middle.

Thread Starter 
Just wanted to post an update.

Tried again earlier today with MX-4. Did the bb-sized drop in the center.

Idling in the mid-50s, full load in benchmarks/gaming mid 80s!!! This is an unbelievable difference, very happy with the results, and now my card is not forced to throttle itself to keep from overheating.

Thanks very much for everyone's input in this thread! It was very much appreciated.

Glad it is the TIM not the hardware issue.

Great, results were very similar on my mother's G73 with AS5, mid 50s idle, mid-upper 80s load.
