Quad SLI 690s hitting 70C

Hi,

When running Heaven, or anything majorly taxing that isn't using v-sync, my cards will start heating up to 60C+ before eventually creeping up and beyond 70C. I have a custom fan profile that attempts to keep them below 70, with the fans running at 100% at this temperature but it doesn't seem to be enough.

I am aware of these cards automatically downclocking when they reach this temperature threshold so would ideally like to keep them under this.

They are in a Coolermaster HAF X case with a fan on the side blowing air onto them, one at the front blowing air inwards, with 2 exhausts in the top and another at rear of CPU. At idle the cards hover around the ~32C area.

Does anyone think it's worth me considering reapplying the TIM on the cards? (they are EVGA ones so I believe I can do that and remain within warranty?). Any other options besides watercooling that I could try?

On a whim I thought I'd have a blast with overclocking them, cranked up the core clock +100 and memory clock +450 - it only made about a 10FPS difference in Heaven, largely I think because it's downclocking above 70C anyway.

(yes, yes quad SLI why would I need to overclock anyway, etc)
 
See i know what the problem is, you have way too much money and should have spent it on something a little more, well, grownup i.e a holiday, buy your wife something she;ll remember etc etc...
Ok jokes aside, seems to me like a driver issue, my brother has a 690 and the temps were hitting around yours, he did a clean install and put the beta on and its seems to of sorted it out.
 
it cant hurt to try changing the tim, after all every time ive reapplied tim it has always dropped my temps. if that doesn't work and you have the cash and it seems you do! watercool those baby's......

Worst I have 2 690's so 'ner' thread ever :D

Only joking. I would say this is around normal for 4 GPU's in one case. The amount of heat being created and the temps outside are making it harder for the fans to keep cool. Water cooling is your only real option but not sure what waterblocks are available for the 690's.
 
Try installing the latest beta drivers. Do you knoe if the 690s exhaust heat out the back or dump it into your case? Try swapping the side fan to suck air out not blow air in, may help a little :)
 
Your temps are fine. Your GPUs won't downclock, they just won't boost up if the temperatures are too high (unless they are hitting 100C+).

I'd change the side fan to exhaust air from the gfx card area, instead of further messing up airflow, i done this on crossfired 5850s and temps dropped by a good 5 degrees :)
 
Yeah also note that your clock will only decrease 13mhz at a time. This is not going to affect you in the slightest with quad SLI.

Are you the guy who had all those problems with one of them in Skyrim when you first bought them?

P.S I never asked back then, have you won the lottery?

No, I just bought the cards on a whim really and paid them off afterwards. I play enough games that I figured it would be worth it *shrug*. To be honest they still give me grief as it is - just tried installing a beta driver and it's taken about 3 hours because I would just get desktop freezes constantly with both cards installed. It even got so ridiculous that when I thought I'd fixed it I put the side of the case back on and the next time I booted Windows I would just get a black screen on the desktop (monitor would go to standby).

Either I've got a slightly duff motherboard, a short, or who knows what. When it's actually working (like as I type this), it's fine.

4 690's?? Jeesh! Even if i had all the money in the world i would bother with more the 2 in SLI!

2 690s = Quad SLI, I don't know what 4 would be (Octo-SLI) but spending that sort of money on a PC is a bit extreme I think. :)

There nothing wrong with your setup

Changing drivers with GTX 690s in sli is a real pain in the behind it can take me about an hour or more messing around (nvidia please get it sort).

As to temps every review I have seen for GTX 690 sli the temps get to about 80c+. Its a mistake to compare them to a GTX 670/80 they are not ment to run below 70c all the time. The best you can do is maximise your case airflow and/or go for waterblocks but that is a bit extreme for something that is working as its designed to.

With overclocking and benchmarks their there for information and a bit of fun so if you get a high temp on them its no big deal you don't run them every 5 minutes. For gaming I run mine at stock settings there is not much in the way of games that could need any more.

Heaven is not very nvidia friendly when using multi gpus. Have a go on 3dmark11 you will see a much better result there.
