Crossfire overheating :(

As in the pics, have you really enabled manual fan control @ 20%, if so, thats exactly where your problem is !
However, if you only did that temporarily then you may want to install MSI Afterburner and create a custom fan profile.

Both fans are @ 100% in the settings.

I'd try as mentioned above, give the case a good clean with some compressed air, try to get a pencil or something to stick inside the fan, as you don't want to over spool them.

which one is the coolest physically? the bottom one or the top one in the motherboard?

a) Dust filters
b) change the H50 so air is going out, not in.
c) change the side fan to blowing in (it looks like it should blow directly on the the cards)
d) clean that sucker up.
e) can you sort the cables a bit better.
f) can you DIY a 120mm fan at the bottom of the 5 1/4 bays that will blow more air on to the cards.


Changing case will only help in part, as it is to do with your motherboads slots that will depend on the gap between cards. A better case will help a bit but not a great deal.

Thanks guys, you're all awesome, I think this post sums up what I need to do, and also perhaps look into buying a different case.
It is dusty inside ( there is no denying that ), but the photo does look worse than it actually is due it it being dark and flashing, so the dust reflects, but.. it's no excuse - it needs cleaning!

I ordered this: Clicky

I'm not on a hugely tight budget, i'm a comp sci student and I need my PC for both Uni and work, and entertainment.. so when it comes to buying equipment for it I don't mind spending a bit extra. I am also looking at a new motherboard, so I have SATA3 and USB3, and perhaps one with the cards further away from each other, but I think I'll wait for the new socket 2011 to be in full swing.

I'll turn the H-50 around today ( it has two gentle typhoons, i'll turn those and clean them but they're relatively new so shouldn't be bad ), and i'll turn the side fan, swap the cards over and reinstall the drivers.
When the air comes i'll clean it out, and then spend some time looking at a new case.

If anyone has one they would hugely recommend, i'm open to any suggestion, it wants to have usb3s on the front, a lot of room for two cards, and lots of space for extra hard drives etc.

At idle, CCC currently shows one card ( My top card, which has the monitors ) at 46 celc, 0 activity. My second card strangely shows 0 for all values ( 0 activity, 0 fan speed, 0 degrees celc, perhaps it is disabled when not playing games, seems odd )
 
To be fair, your case and cooling should be fine enough to keep your cards cool, as suggested previously, ensure your H50 is pushing air out of the case and ensure your front case fans are bringing air in.
What I did with my case was move anything in my front bays to the very bottom of the case then ensured there was good airflow from the top two fans.

Also, in my experiance its best to have the side case fan blowing in supplying the GPU's with fresh air.

Just out of interest - have you tried running the cards seperately (as in, taking one out)? Do they hit the same temps?
 
Hi JaffAWood, thanks for your advice!
I haven't tried them in seperately, perhaps it's something I should try.

I have some more pics for you...
The bottom card was filthy,.. full of dust ( But this wasn't the one overheating I don't believe ) - this was at 58 celc but only 11% activity.

I took the H-50 off, turned it around, and cleaned those fans and the radiator ( which was fairly dusty ).
I then took the side fan off, turned it around, and cleaned that fan.
I took the spot fan off, cleaned that, and put it back on.
I'm considering a new side fan also, I have a spare somewhere so I can have two side fans, but it's much much cleaner now inside. My top card idling is now at 38 celc rather than 46, but I did also swap the cards over ( top is now bottom ).

Speedfan is showing my CPU at 19 celc idle, I have the window open though and it's not been on long ( It's overclocked from 2.6Ghz to 3.8Ghz, so will no doubt rise ).

I played Battlefield yesterday, and turned on the crossfire status icon, which showed in the top right, so I think crossfire is enabled and working, but I will delete the drivers and reinstall anyway, to make sure.

I dont do it all the time but in this situation id also run driver sweeper.

In BF3, according to AB - My GPU usages are pretty much identical ~1/2%

Just a thought - is your PSU ok. No whining or buzzing or anything? Especially under load... Ive had many many random problems caused by the PSU checking out.
 
No buzzing or whining... It's not hugely powerful though, it's a Corsair TX650, but I hope it's enough for this setup?

I just removed CCC, booted into safe mode, used driver sweeper, restarted and reinstalled from the AMD site - and took off the front panel to clean the fan whilst I was restarting.

It's now reporting 55 celc for my top card, 0 for my second card.

That's not totally idle though, it's got two monitors, one showing skype etc, the other browsing the net

55 is ok. In my old case the 6950's were as close as your GPU's are and just playing video on the TV it would sit around there. new case and a fan in the middle though and it sits around 30 doing the same thing!
 
Looking at the picture, the biggest problems are:

a) the top card is sitting directly on top of the lower card with amount no gap at all

b) that particular model of HIS cooler is know to be crap due to cutting corner, and also dump the heat into your case so if you don't have exhaust fan for the lower half of the case the heat will just keep building up more and more and get recycled back into the cooler

c) there far to much dust inside your case...do you not have dust filter for the intake fans of the case?
 
I know its a bit ghetto, but what about a PCI-Express x16 riser cable and shifting that second card down one slot? The gfx card bridge would have to be long enough though..

Plus all those other suggestions and cracking out the dyson.
 
Yup, so my case is a fair bit cleaner.
A PCI-Express x16 riser? I'll do some googling :).

I just played some more BF3, temps looked a little better but again, the second card showed at most activity of 12%, whilst the first was 100%.

I'm downloading Unigine Heaven to see if benchmarks are close to normal...
I can compare to the ones found on a review:
V2 / DirectX11/ Shaders High/Tesselation normal 1680x1050, on the review it comes in at 1809 in crossfire

Do what i do its a bloody must and trust me it helps with temps.

basicly get a piece of paper or carboard and you want to sqeeze a small peice inbetween both cards so that you can make the gap in the middle slightly bigger, then you want to take that spot fan you have and hover it over the middle back end of the cards so that the air is being pushed inbetween the cards then get yourself a 120mm fan and place it above so that its at a angle pointing at your mobo northbridge.

trust me it shaved loads of my graphics cards temps.

You can see what i did, and it works awesomely trust me. :)
