ohhhh another pre-overclocked system from ocuk that isn't stable..
try everything at stock first mate. maybe its the overclock thats not stable enough

Yeah it seems like that must be somthing to do with it then.
Ill give that a look this eve
The 2 top PCI-e slots run at x16 speeds so these will offer the best performance and are the reccommended slots to use:
If however you are concerned by the top card becoming too hot (which it doesn't seem to be - as others have said 80c is acceptable) you can always move the lower card down to use the PCI-e lane at the bottom. Unfortunately this lane only runs at x8 speeds so you will lose a bit of performance - not a huge loss, but a loss nonetheless.
You could always manually increase the card's fan speed to compensate for the high temps?

You could always overclock the cards to make up for the performance drop
the card will probably still run cooler.Its a few %.
Yeah if the performace loss isnt that much I think Ill give it a go, assuming the bridge still fits.. I dont like the sound of manually setting fan speed etc

The Std bridge is not long enough i have tryed it also to save you the headace you might find that the dual cooler design will not seat in the 3rd pci slot because of the pwr/sw connections on the motherboard are in the way. if you feel ok the best way to reduce temps and keep the speed is change the GPU paste to mX3 dropped my temps by 10c laod
Knew I should have gone with the Rampage II! Might try to find a longer bridge...
What you suggest sounds a bit complicated for me!!

changing the paste was a 5 min job at best, however it was on 5770 if you can google and see how the cooler shroud comes off the paste is really easy to change. Might want to check with ocuk if this will trash your warrenty 1st though. The bridge's are about £5-10 if you want to go down that route. My honest advise is leave them alone mate 80c is nothing you can prob make a custom profile in MSI afterburner to get them down so more.
Why don't you like the sound of it? It is as easy as a few clicks of your mouse.
I might give it a go if there is no risk/side effects...I'm a proper novice at all this though - not had a pc since 1998!
I have two 5850's in a UD5 and the max i've seen my top one get to is 72c. That was on a warm day, benchmarking in crysis for quite a long time. Otherwise, i don't usually go higher than 68c.

Yeah mine are 5870's but from what I'd read, I did think my temps were a little high considering it had only been on for like 30 mins
I'll run a crysis benchmark for a couple of hours and see if anything melts i think
gpu's are not like cpu's. graphic cards run hotter, 80c is perfectly normal for an 5870. of course a 5850 runs alittle cooler because its at a slower clock speed. also different cases give different cooling performances...
my 5850 get 63c under load at 800/1250
