Help with crossfire overheating issue

post #1 of 11
Thread Starter 

Video should explain it all.

Sorry for the shakiness, it's difficult to navigate a keyboard and mouse while holding both a camcorder and a mic.

looks to me like you thermal grease is dried out , try to set new one.

I am going to upgrade my cooling soon during which I will definitely redo the TIM. I'll take a picture too and post it on here.

I've noticed however that these temps only occur in crossfire mode. In a single card mode, my loads normally are around 60c. (with automatic fan speed)

Edit: sorry by single card mode I meant with only one GPU present in the system.

Haha fellow kiwi ova hur...

I have the same kind of setup just wondering what version of catalyst are you running? as Im having some problems changing fan speeds in my AMD Overdrive lol they just dont want to work

My idle temps are about the same as yours, as i'm also running eyefinity 2x5850 about 50 for top card and 30 for the bottom card, under load the max i have seen is about 82 degrees after long periods of testing with the auto fan profile(although i havent overclocked mine), does your mother board allow you to drop your 2nd 5850 down a slot? I have a single pci slot space between mine which hopefully lets it breathe a tad, also i chucked in a decent fan at the bottom of my case sucking air in and blowing up which dropped temps by a few degrees. does the same thing happen when you are at stock clocks?

Catalyst 11.5 (no hotfix)
My motherboard allows it, but my case doesn't.
Yes the same thing happens at stock clocks.

Unfortunately I am getting the same load temps as you are.......on 100% fan speed.

Can someone help? I have no idea why the temps are ridiculously high. Even though it is a crossfire setup, no one else seems to be getting temps this high.

Is it possible to move one of the 5870's into the bottom slot? (can't see if PSU will be in the way).. It runs at x8 so shouldn't cause a problem for games.

Though those temps are crazy high for 100% fan speed.

I would look at opening them up, give them a good clean and replacing the TIM.
 
Fun inside...

My case is too small to do that unfortunately.

As you can see in the video my card is completely exposed and open so I can clearly see the entire PCB. There doesn't seem like there is anything interfering, it just runs incredibly hot.

I'll go order some TIM I guess and do a reapplication.

Hey there-

I actually had an Antec 902 before with a CF setup. Even with the good amount of air flow the case provided, I was never able to calm down the temps of my OC'd 6870 CF (950/1200). I would see around 80-85 at about 30 mins into gaming (~40-50% fan speed). I never saw anything upwards of 90s, but I was still a bit worried.

I toned down the OC a little bit and downloaded msi afterburner for better fan settings.
I have recently upgraded my case to a 650D, which is similar airflow and added some more with a 120mm fan mounted as shown in this pic:



I was wondering if it could also be caused by the layout of my mobo, due to how close the PCIe slots are. It's the only way I can set my GPUs up on the mobo. I definitely see my top GPU getting MUCH hotter at idle and load.

The fan profiles and extra 120mm helped the temps a bit, but I still see temps of ~75-80 in newer games. It seems you already have a 120 blowing on the side as well from your video, and the temps are still that high.

My gpu fans never run above ~60%, and then I am able to drop them down back into the 70s.

I don't know if I have provided much help, just kind of joined in your concern. At this point I would probably reapply TIM. I am not too familiar with your GPUs, so I am not sure if they are notorious for those temps.

I realllllly want to go water cooling, but that's likely next build due to needing a new PSU in addition to all the h20 components. I wish we could spread out our cards a bit more on our mobos =(

I hear you man

I'm eventually going to upgrade to water cooling as well. Then I can determine if my cooling actually sucked or if there is a manufacturing defect with my cards.
