670 SLI temps

[HonoredShadow]

My cards are not overclocked. My temps in a warm room (22deg ish) are at 70deg in Unigene benchmark.

Should I be concerned? Will my cards 'down-clock' themselves? I no nothing of down-clocking.

If this is a cause for concern how do I raise the fan speed? I do have Afterburner installed but it says fan Auto and have never touched any of that. Maybe I don't have too.

Any advice would be great!

The Kepler cards are fine to 95 C I believe and load temperatures of 70-80 C are perfectly normal when using the default fan profile. 70 C for Unigine is perfectly fine too considering its running uncapped without v-sync.

If you're concerned then try a custom profile that ramps up the fan speed earlier than the default one does. I have mine set so the highest temp I've seen in any game or benchmark after hours of running them has been 76 C. Most games don't exceed 70 C anyway, especially now I have SLI and use v-sync to reduce the workload between the two cards.

I would only worry about the temperatures if they climb past 80 C personally.

Youre fine, but boost clock isnt as high once the threshold of 70c is hit.

[HonoredShadow]

Thanks for the reassurance. Is that right about boost clock? So are you saying I need to cool the cards more to get more of a boost?

Its fine,so what when you hit 70c it will drop clocks a whole 10 big deal.
I would just set the fan speed up or make a profile most cases you will not see 70c.
If you have ab open while you run heaven you can see the drop if you wish,it does keep dropping as you get hotter too.

Ok. Thanks. Never made a custom profile though. Any hints or should I trawl YouTube?

Scared it will go tits up!

[cowie]

I just turn it to max with a saved profile and use it before i game,you must really set this to your own needs.
If turning up the fan speed makes it go tits up good riddance.
