5850 Crossfired Temps too high??

Hello all!

Can someone please give me some advise. I have a feeling my GPU temps are too high. I just formatted my computer installed the latest CCC. I'm using dual monitors with GPU scaling to sharpen the fonts on my 2nd monitor. Cross fire is enabled on my 5850's.

CPUID hardware Monitor is showing my value at 55 C constant with a variation of +1 or -1 on both cards during no load. I have not checked with load as i have not installed any games. Is there something wrong with my GPU's?

You might want to use MSI Afterburner. It won't work for overclocking crossfired 5850s but it does allow for custom fan profiles on both cards. Mine right now are idle at 41C and 31C with fans at 14%. Under max load both cards don't really go over 68C at 70% fan speed. Granted, 2 monitors probably needs a bit more power/clocks even at idle. It would be good to see in the Afterburner graphs what you're at.

That is fairly normal if you are using 2 monitors. In order to run your 2nd monitor without flickering, the cards can't idle at as low of clock speeds as normally achieved with one monitor. The result of the low idle clock speeds with 2 monitors, is one will flicker horribly.

so 55 idle is normal for dual monitors? will this cause problems later on? i'm kinda of a temperature freak! aftermarket cooler maybe? anyone can recommend for dual 5850's, but i'm already running 10fans. (3intake, side intake, inside center intake, dual back exhaust, top 200mm exhaust, and heat sync has two) so is that really needed?.

My core temps are 32-39 at idel so those are good.

55C isn't too bad. Have you checked what the idle speeds are? If you really feel proactive you could flash the GPU BIOSes to idle differently. Bystander points out the idles need to be higher than regular (157/300) but you could try and see if it works at, say 250/400 or something like that which would lower the temps. You might be at 400/900 or even 550/1000. Anyway, 55C isn't going to wreck anything. What are your load temps tho? Like in FurMark.

Also, the default fan speeds are very slow, you can definitely lower the temp just by increasing the GPU fan speeds with Afterburner.

I just formatted and didnt run anything on load yet. The thing is i dunt want to change any of the STK settings. I'm a fan of STK settings as i see that it would best surve for longivety.

I'm just wondernig if anyone else has 5850 crossfired with dual monitors and what there temps are?

I have 5870's in CF, with two monitors, and I idle about 55C.

Also, keep in mind, when at idle, the only card that gives a temperature is the primary card, which as poor airflow, due to a 2nd card being right next to it. The 2nd card doesn't show it's temp in CCC, but it reads 5 degrees cooler at ~50C when using GPU-Z.

really? what are u getting at load? what games would be good to test my 5850 xfire set up at this time? I'm plannig to play sc2 (which i was in beta -but didnt support xfire to well -hopefully they fix it when release comes out) d3. and right now i havent picked up anything -thinking going back to wow for sh*ts and giggles.

You do realize that most cards idle at much higher temperatures than that. At load I get up to 80C. I usually use Vsync as well, which can reduce your temps.

All my Nvidia cards idle at 65-80C.

I often run with 3 cards in this sytem, in which case the 9800GT, which has the best circulation, idles at 70-78C.
