1st card temperature rise when in SLI - Page 2

post #11 of 16

Nevermind. I see he states it's at idle. My mistake.

 

Adding a side case fan will certainly not hurt though, still. It's going to get hot in there when he does start doing stuff which is the norm with multiple GPU configurations, regardless of the amount of monitors.

Check with HWMonitor -- you'll see one card using higher voltage than the other. 

This, I thought my card was going bad because the idle temps rose about 12 degrees, but it was in fact because I added a second monitor. From what I understand it is from the voltages. When gaming they both run at the same temp as usual.

You'll be fine bro dont worry about it too much.

I also have two monitors on my cards, and they're always at 100% load due to BOINC/F@H. And the top card is usually 78-80c and the bottom is 68-70c.

SLI places a heavier load on the display card. I don't know the mechanism behind that, but it's just like that.

Yes, I noticed just now. I ran msi kombuster and the 2nd one downclocks to 50mhz and voltage is lower

Run your temps without a second monitor plugged in and there may only be a 3 or 4 degree C differnece

Yeah, a side fan will help.

Right. He's fine... and yes, when gaming the voltages will both be the same. Adding a second monitor ups the voltages because nVidia drivers thinks that it needs to compensate for the added "load". However, using MSI Afterburner, you can manually turn everything down again to the lowest clocks/voltages and they'll be equal again smile.gif (or in my case, my top card is often cooler than my bottom card... I have 40-45F ambient temps often). I use separate profiles on Afterburner. Easy.

That is probably for the reasons that everyone originally thought for the OP -- when running at 100%, the heat is much more intense which is probably why your top card is running so much hotter, as the more intense heat is traveling up to the top card. It's not SLI itself that's placing the heavier load, necessarily. SLI itself places 0-load on the GPUs.
