ASUS GTX 580 directCU II - SLI Temps

post #1 of 3
Thread Starter 
Have been runnning a single card for a few weeks and generally idle temps are sub 40, load about 65 . . so generally really happy with that

Added a second card last night and seeing some really big diffs in temp between 1st and 2nd card.

Under load the top card is pushing mid 70's whilst the bottom card is still in the 40's

Now the clincher is that I have a Revo drive in the only other slot available which is right under the primary card, which pretty much blocks one of the fans. Air can still get in there as there is a gap at the side and the rear fan is fully clear but obviously it will be impacting airflow.

Can anyone confirm what temps they get for SLI of these cards .. I am not sure how much off these temps are compared to an unobstructed set up.

I have bought some PCIe cable extenders so i can mount the revo at the bottom of the case but won't get them for a few weeks and keen to weigh up pros and cons of changing the config.

Thanks

Hi,

If you installed a second card afterwards, it is NOT SLi yet.

You manually have too enable SLi in the driver. (To do this right click on your desktop somewhere and select "Nvidia Configscreen" or something like that. There you have to choose the "SLi and Physx" Tab, and there you have too Enable SLi.

Also you have too connect the 2 cards with the SLi bridge

I'm not saying you didn't knew this, I'm just trying too help...

Ok, its been a while since you've asked this and I expect you already got your answer but, I'll answer anyway

ASUSfreak is probably right in suggesting that you may not have enabled SLI yet.
Nevertheless, the SLI bridge is more of a help than a necessity. While it might give you some extra fps (due to unclogging the mobo's pci lanes), SLI will work regardless of you having a bridge in place.
The temps you should see when gaming are, according to guru3d.com, are:
Top card a70-75c, and bottom card at normal levels, 60-65C.
That is if your cards are close together.
Anyway, nice rig!
