EVGA 260 216 overheating after OS reinstall

This is what I wrote on the EVGA support ticket:
______________________________________________

I reinstalled Windows 7 x64 about 2 weeks ago and the idle temps on my 260 rose 10 degrees C when idle. I use Precision to OC and monitor temps/fan speeds. GPU is set at default clocks and default 40 fan speed unless gaming. Right now, I'm idling at 64 degrees. Room temp is 24 degrees C.

I checked the fan filters on my case and the airflow is good. I haven't blown out the fan/hs with compressed air yet. I will once I get paid, but could a little dust cause a sudden 10 degree increase? Like I said, the temps were cooler before reinstalling the OS, but what could the problem be? All drivers are the most recent available.
______________________________________________

I've gotten some good advice on this site before, so I thought I'd ask here too. You guys/gals have any suggestions?

Thanks

Maybe you moved the GPU cooler somehow? An os re-installation will do basically nothing that could raise temps like that.

Thanks for the quick response.

I didn't even open the case, only cleaned the outside filters. Just looked inside and dust is building up, but 10 degrees?

This machine has seen plenty of OS reinstalls and never has anything like this happened before.

I'm worried the card is failing, but feel good about EVGA's lifetime warranty if I need it.

Dust may be blocking airflow through the GPU cooler. I would pull the card out of the system, and maybe use small flashlight to check if the cooler is dirty/clogged.

Is the GPU fan still working properly?

The fan works. I pump it up to 100% with a 700/1410/1080 OC and temps drop to the mid 40's. Even after a long game session, the temps barely go over 60 when the fan is full speed. It's the default clock/idle temps that have me puzzled.

The card sits with the fan facing down in my case so I'll have to wait until morning to take it out and see. Dust could be an issue if my CPU cooler is any indication. I just feel like the sudden rise is too sudden, y'know?

Most likely the software is reading temps wrongly.

Have you tried different programs?

I've got GPU-Z steadily monitoring in the background and EVGA Precision both reporting the same temp. HWMonitor also reports back the same.

Windows 7 probably installed 196.21 drivers and they are a mess.

Try removing them with Driver Sweeper then install 195.62.

It seems funny to me a simple OS install would cause extra heat but, like I said, the 196.21 drivers are no good. They even prevent you from overclocking. It had me stumped for a while and it's easy enough to try this before anything else.

I am using the 196.21 drivers, but I installed them myself.

Thanks, will try and report back this afternoon.

Additional Comment:

OK, I cleaned as much dust gunk off the fan blades as I could without having compressed air handy. From what I could see with my little flashlight, the heat sink fins looked pretty clean.

I also uninstalled the 196.21 drivers, ran Driver Sweeper in Safe Mode and installed the 195.62 drivers.

My GPU temps are at 62 idle. With this card, instability tends to occur after about 80 degrees C, which I've only reached while running stress tests like Furmark.

What do you guys think, are these temps something I should consider RMAing the card over?

Additional Comment:

I reinstalled Windows and that fixed it. Temps 49-50.

Thanks for the help guys.
