SLi GPU question

post #1 of 7
Thread Starter 
Hey everyone quick question here regarding what the two video cards do during idle, Right now while idle at the desktop and on OCN of course My 1 video card is idle at 405 core clock, While the 2nd one is 41 core clock. This actually makes 1 GPU 15 degrees hotter and the fan spins faster than the 2nd gpu.

My question is, is this normal? Does the primary GPU have to be at this GPU clock in order to render the aero desktop and anything basic besides games?

Thank you

I see my gpu1 gets hotter when watching anything that supports gpu acceleration including youtube but on desktop idling I get same clocks on both ( I do have older GPUs tho )

EDIT: Forgot to add that my first gpu is hotter too but thats mostly due to the heat form the second gpu...

This is by design/normal, and it's because you're running two monitors. If you unplug one of them you'll find both cards will drop to 51MHz core on idle, and their temps will become closer to equal (though the top card is always warmer by around 3-7C in my experience). You may have to restart to see this happen though, not sure.
