High GPU temps, what are my best options?

The fan might be OK, especially if the inside of the heatsink is restricted by dust.
Hopefully you can get away with just a good cleaning and thermal compound replacement.

Your 6970 should have screws on the back holding the heatsink and fan on. Removing them should allow everything to come apart. Cards vary, but you'll see.

The fan shroud may have more screws accessible after removal from the card that would allow for better cleaning once removed. Lay screws you remove nicely so you can keep track of where they belong and when they were removed.

Clean off old thermal paste from GPU die(s) and reapply new. I think that card has two GPUs. Clean off the heatsink's contact patches too, being careful not to damage thermal pads on RAM and voltage regulators. Isopropyl alcohol works well to clean off old thermal paste. A new clean coffee filter makes a good lint free cloth.

Apply about a grain of rice worth of thermal compound to each gpu and spread with an old gift card.

depending on the paste you use, it would be wise to not game on it for 12 hours after applying paste.

I just repasted my 7970 I was idling at 70 until it cured.

I use an AC Twin Turbo II on my GTX560. It's massive so you better have space. The GPU itself takes the PCIe and then the cooler itself takes up 2 PCI slots.

The cooler is awesome; my GPU idles around 24C/26C and load is 50C. Not only are the temps awesome but my PC is completely silent now.


Yeah, okay, I'll need a bigger case then : /

I'll post a picture soon, you'll see, it's a bit ridiculous how cramped everything is.

Thanks for the in-depth explanation!

I assume I should not use too much Isopropyl alcohol and clean it thourougly after so my GPU doesn't ignite, huh. x)

The alcohol will evaporate very quickly.

this^

if you're overly worrisome, let it sit in sunlight for a half hour on your table or something.

Take it out clean it then take the fan off and replace the thermal compound with some arctic silver. I was idling in the high 50's and getting over 80c load. Now it idles at @ 43 and gets to about 72 under load.

Oh and please upgrade your system. Its really not that expensive if u stick with amd.

Oh, I plan on upgrading for the Witcher 3 probably. But right now I'm trying to save for a Cintiq, and that crap is super expensive :P

I have this cooler. It's pretty darn good and keeps my 680 way cooler than stock and is pretty damn silent. Though be warned you will have to take the shroud off your card and do some manual heatsink application to certain parts. just be careful and you sould be fine

The isopropyl alcohol should evaporate quickly, especially if higher purity like 90+%.

After applying and spreading thermal paste, I like to tighten screws in steps and in a criss cross pattern to help spread thermal paste evenly.

There are videos online of GPU thermal paste replacement if you need any more details.
