Re-applying thermal paste on a Gigabyte GTX 670 WindForce X3 OC

post #1 of 11
Thread Starter 
What method is best used in reapplying thermal paste to my card? I disassembled it and saw that it uses copper heatpipe direct touch. If the technology used is the standard (non heatpipe direct touch), I would always spread the TIM evenly for a bare-die chip and a half-pea sized blob for a CPU with a heatspreader. For this particular application, what is the best thing to do?

Thanks.

I use the cross method for gpu. But i am sure its not the best method redface.gif

GPU dies are vastly larger than 32nm CPU dies. I used an X as well for my 560 Ti 448 FTW see rig

X where? On the GPU die itself or on the base of the heatsink? Is the heatsink of your card direct heatpipe touch as well? Take into consideration that there are "grooves" in direct heatpipe touch heatsinks.

Where do you apply paste on cpus? On the heatsink or the chip?

In the CPU. But I read somewhere that some people do it on the heatsink.

And by the way, here's the heatsink of my GPU:

I have yet to find a single method that works better than "tinting", but I haven't tried it with a GPU using HDT cooler. Basically, you just "grind in" the TIM to the HS and IHS as best as possible, then use a fine-edged surface (razor blade for me) to scrape it off, leaving only trace amounts filling up the itty-bitty microscopic gaps and giving you a flat surface at a microscopic level. Then, you simply use 1/3-1/6th the amount of TIM you would otherwise, just enough to give a nearly-invisible coating between the IHS and HS, and you get awesome temps.

I've used this since I was running an AMD FX-51 with a tower air cooler and it's never failed. It allowed me to hit 2.61Ghz on the aforementioned FX-51 (2.2Ghz stock), on AIR, when most people were struggling to get 2.5Ghz on water! It also let me OC my X800XT-PE by over 30% for both GPU and VRAM, but this was with first a stock cooler, then a Zalman VF900 and then VF3000, so I couldn't speak to the HDT + Tinting thing.

If you can get it to work, though, it REALLY works! I find that PK1 and other thick and "gritty" pastes work best, with watery pastes like AS5 being absolutely awful.
