UD5 Crossfire

Mind you they did say it was running stable for 20 hours before they shipped it to me (it had to go back 1st time due to faulty graphics cards - both 5870s were duff apparently!)
 
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?
 
If the other slot is 8x I say move it. Running cool the first card is less likely to die, the fan is going to spin less (quieter).

You could always overclock the cards to make up for the performance drop :D the card will probably still run cooler.

Its a few %.
 
theres afew people on here that bought pre-overclocked system from ocuk that hasn't been stable due to the overclock..

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.
 
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
