85c for hours on end ok?

[StonedPenguin]

Sorry for asking a question thats been asked before.
Some people say keep it under 80c, Some say keep it under 90c..


n580 @ 1.125V sits at 84-85c when in BF3 and this can be 6 hrs+ a day.

Will it degrade the chip or am I worrying over nothing? Whats a safe limit?

cheers

You're worrying over nothing, 85 degrees is ok for a GTX 580.

If you want to improve that, I always strongly recommend replacing the stock paste on MSI custom cooled cards, as MSI are terrible at applying thermal paste to these cards. I got a massive temperature drop from doing it on both my Cyclone GTX 460s and TFII 560s.

Thanks for putting my mind at rest bhavv.

I have some Arctic Silver 5 paste, Would this be ok to use?

No dont use AS5 on a graphics card!

It is electrically conductive and could easily mess it up.

Only use MX3 / MX4 on graphics cards.

I'll make an image on how to custom paste up Nvidia GPUs with MX3 / MX4, give me a few mins.

For good coverage and the lowest temps I managed to obtain, I used two strips of MX3 around 1/3 of the way from the top and bottom of the GPU, something like along the red rectangles here:

My temperatures reduced by up to 8 degrees when idle, and 5 degrees under load. Better thermal paste application works wonders on the TFII coolers and lets them pull a lot more heat away from the GPU.

Thanks again mate, I had no idea about that

I'll get some MX4 and report back before I take the cooler off (This scares me a little )

Thank you!

YIKES .. as the gentleman above me stated DON'T USE ARCTIC SILVER ON A GPU. It conducts electricity. I personally would use this thermal paste, it's a smaller amount of the 24k IC Diamond and more then enough to do your GPU many times and CPU and it does not conduct electricity and is non capacitive too.

IC Diamond 7-Carat Thermal Compound (1.5g)

PEOPLE WITH ATI/AMD CARDS be even more careful because the GPU has components on the outside of it too, Nvidia is a better designed GPU with a cover that hides all the componets but again I will never use a Thermal paste that conducts electricity or that is not non capacitive anymore. Just not worth the risk in my opinion and as I said the IC Diamond is a real winner to me, it covers all the bases and does it with fantastic tempertures.

The best Thermal paste on the market I think and does what it says on the tin .

Thanks for the image showing me where apply the TIM bhavv, thats very helpful

Thanks purgatory ill have a look at it

 

[bhavv]

Oh yea, that Diamond Carat stuff would be better than MX4 now. I still have half a tube of AS5 and MX3 left.

I should really throw the AS5 away, its nasty evil stuff.

AS5 is very good. Just be careful.
Used it countless times in the past with no problems at all.
