Moved GTX560Ti 448 to different PC, and now temps are 20C higher???

I've got my trusty EVGA GTX560Ti 448... it's been in every machine in my sig at one point or another, bumped to the next lower machine as I upgraded. It was in my HTPC, where it did very well... idling at 30C and streaming video at 32-34C without issues or noise. I swapped it out, back to my DESK PC, where it originally was....

Now, all of a sudden, it idles at 40C (when monitors are asleep) and runs 2x 21" 1600x900 monitors at 50-55C??? :eek: AND it won't stream video worth a crap.

I had updated drivers, reverted to older drivers, clean installed drivers, made sure the iGPU was disabled... but nothing will get those temps down below 50C when the monitors are on. When this GPU was in this PC originally, I never had problems with the temps or streaming (in fact, it was my gaming rig at that time, too.) Both the DESK and HTPC are the same case... and basically the same setup.

What am I missing here...?

Chech with GPUz what clockspeeds it is idling at. It may be a lot higher than with just one monitor.

Sounds possibly like a fan issue and probably needs new TIM. I just went thru a similar problem with an older Nvidia card. A disassemble of fan & heat sink allowed me to clean fan & heatsink, add a small shot of WD40 in fan motor, & new heatsink grease had it back to normal rather painlessly..

I don't think so... we are talking pulling it out of one machine and putting it in another.

Was it previously powering 2 screens? That is likely the problem if not.

No... it wasn't; and I didn't think to pull the DVI cable on the 2nd monitor to see how it did with just one. Come to think of it, I didn't have my 2nd monitor when it was originally in my desktop.

That'll be it then, double check Idle clockspeeds with GPUz. From what I remember Fermi wouldn't clock right down with 2 monitors like it would with one.

That's it... and now that you mention it, I had forgotten about the 2 monitor problem. I plugged in the 2nd monitor and the GPU clock went to 100% and temps rose 10C. There is a fix for this, I'll have to dig through my notes for it.

Good call! :thumbsup:

Yup, Fermi GPUs use quite a bit more power when hooked up to dual monitors:

You can try setting a new profile in something like MSI Afterburner for idle state, I believe the memory clock doesn't downclock.
