Gtx 480 sli

Hi Guys

I have built my new system this morning, with the R3E and 2 x GTX 480's in SLI..... But my idle temps for the GTX card are very high 79 Degrees...... I know these are hot cards, but surely not that hot....

Any ideas guys

Thanks

Hay

Are they directly next to each other or is there at least one slots width between them? As I've read that NVidia recommend at least a slot gap to help with SLi temps. I can only see it being airflow related if you're running them on air tbh.

Btw, SLi GTX 480's? WOW is all I can say!

yes they run that hot get uste to running them at 100% fan speed to keep them cool'er

but thats some graphical power there tho well actualy thats some insame system lol

wow you have some amount of money hayley

Yes I have left one gap between the cards, the only thing between them in the sound card....

What program would you guys recommend for controlling fan speed etc ????

evga precision as its the best one IMO

have you OCd the cards? as you dont need to lol

I'd probably think that the sound card would impede airflow across the tops of the open-to-air heatsinks, effectively incubating them, but I could be wrong. Have you tried with only one card installed to check the difference?

No I have Oc'ed them..... not intending to either.....

Have got a render test running. putting 98% load on the cards, temp is 91 degrees (OUCH!)

I have just installed EVGA precision and have noticed only one of the cards is running at 91 degrees the other is running a 67-68 degrees - on 98% load - fan running at 92%

Is the higher one the 'top' card with heatsink adjacent to sound card? If not my theory is flawed
