Hi Guys

I have built my new system today, R3E with 2 x GTX 480 in Sli, one of the 480 idles at 70 - 80 degrees the other idles at 50 - 60 degrees.

I have left one PCI_E between the cards, the only thing between them is my soundcard which plugs into the PCI_Ex 4.1 slot..

Surely that first GFX card shouldn't be idling that high??

Any ideas guys

If you're using two monitors the cards will not clock down and therefor run at a higher idle temp, if not dual monitors then the 480's do run hot and today is a very hot so...
 
They cards run really hot but there ok for up to 105c. The top card will be the hotter one, if you want to cool them down you could stick a fan on your side window blowing directly into the graphics card it could lower your temps by 20c +
 
I have 480's in SLI and no matter which is the top card, one in particular is always 4-6C hotter than the other. This has even carried over to them now they are watercooled. The card which gets liquid first (the card which was always hotter) is still hotter than the second card in the loop.
 
Someone advised me to take the soundcard out inbetween, so have now done that, and this is it..... let me know where you think i can improve

Cheers guys

Looks like you have very good airflow, I doubt the small soundcard would make much of an impact on temps as it would not be blocking any fan intakes. 80c idle is hot, it may have a poorly seated HS or poorly applied paste between the GPU and HS.
 
this is 20 - 30 degrees hotter than the bottom card..... and these are idle temps as well.... 80 degrees underload i could understand, but not at idle
 
Ok it says on EVGA front screen

Shader Clock = 1401 (Same on both cards)
Memory Clock = 1848 (Same on both cards)
Fan Speed 56%

How do i find out the other settings?
 
Ok Found it

GPU1 Core Clock = 405mhz
GPU2 Core Clock = 51mhz
GPU1 Shader Clock = 810mhz
GPU2 Shader Clock = 101mhz
GPU1 Memory Clock = 1848mhz ---- Usage 124mb
GPU2 Momory Clock = 135mhz ---- Usage 124mb

Why are the numbers so different between cards?
 
Something running in the background in windows can trigger higher clocks, I know windows media player has a habit of running in the back and it can trigger the clocks running at 400Mhz used for things like HD movie acceleration. Check task manger for things that may cause the clocks to go up and disable them to see if clocks go down.
