Anyone changed TIM on their XFX 6970?

post #1 of 16
Thread Starter 
My XFX 6970 runs at 75-80C under load with 65% fan, which is a bit high for my taste. I was thinking of changing the TIM, but didn't want to bother if it wouldn't help any way. Anyone changed the time on their 6970? I have the rev 1.1 btw.

75-80c isn't bad at all, in fact it's pretty good for a ref cooler.

So it's normal for it to run at 75C with the fan running at 65%??? I know they're safe up til about 80-90, but I thought the fan generally runs more in the 50% range, this thing gets loud when I'm playing games.

I have thought about it, but I am not sure if it is worth the effort. In crossfire, they run really warm. I run about 82-84C at 68% fan.

Using the GPU duct in my HAF X and a Ultra Kaze 3000 at roughly 50% made a 2C difference, and stabilized the temps.

It also doesn't help that it has been scorching hot here in Kansas for the past few weeks. It has been 100+F everyday.

Edit: This is with ambient temp of 26-27C.
2nd edit: Can't wait for winter!

Hmm. I'm not running crossfire and it runs about 76-80F in my room. I do have a second video card (4830) that just idles at 40C since I needed it to use s-video out from time to time. But the temps were like this or about 2 C lower before i installed the 4830.

I can definitely say from experience that not all cards are created equal. Whether it being the quality of the PCB or the TIM application, my cards are very different.

I tested each one in top and bottom positions, and the one that sits on the bottom is there for a reason. When it was on top, I had the crank the fan way up to keep it under 90C. And for an even better indication, it runs the same temp as the top card!

Also, both cards are v1.1.

Interesting. Didn't think you'd have that much of a difference. Never thought of replacing the TIM on the hotter card?

I have thought about it, but I just haven't had time to lately. It would be my first video card disassemble, so I would take extra caution when doing so. I will probably just leave it as is so I can see the affects of winter temperatures. I should also have more spare time in the coming months.

From what I have read, if you do decide to change the TIM, it is best to notify XFX via a support ticket. That way they are aware that you have made changes to the hardware, and you have proof that they approved it. This will help prevent issues if you ever have to RMA.

I'm thinking it may have something to do with your case's airflow.

The P183 seems a bit cramped from what I've seen on Newegg and with that will come higher load and idle temps. Is there any way for you to add a fan in front of the 6970 in say a drive bay?

I've got two 580s in SLI sandwiched together with the top card literally sitting on the lower and the temp difference is only 9-11C because I jury rigged a Scythe S-Flex E to my hard drive cage blowing air directly at the cards.

Just gotta figure something out that will work man. Add some fans. Do some cable management, or in the absolute worst case get a new case. :/
