Sudden idle GPU temperature increase

Hey,

I've been running my setup for about 3 weeks now as is, and for a few weeks prior with a different psu and only one graphics card

My current setup is
i7 2600k @ 4.6ghz
Asus maximus extreme-z mobo
GTX 580 SLI
Corsair 1050HX psu

Now normally both cards are within 1-2 degree's of each other, I monitor them frequently in MSI Afterburner. idle they sit between 35-37 degrees and under load, in something like Battlefield 3 on Ultra they both sit between 60-63 degrees.

Now for whatever reason my GPU 1 idle is now sitting 10 degrees hotter than normal at 45 while GPU 2 is normal at about 36. I'm really puzzled as to what could be causing this, was debating swapping there spots, but I'm not sure that would solve anything. I opened my case and from what I can tell everything is working fine.

Is it possible that one of the fans is crapping out and not running as efficiently? I have the Gigabyte GTX 580's.

Did you update your drivers during that time?

No drivers or system configuration underwent any changes.

Are the clock speeds the same on both at idle? What about GPU load?

clock speeds are identical, both GPU at 0% load.
