GTX 560 Ti voltage

I looked around and could not find an answer to my problem so here it is:

I have a GTX 560 Ti 448 cores and it makes a weird metallic, high pitch very loud noise when I`m playing BF3. It happens no matter what settings I am on but stops on less intensive moments.

E-vga said it might be an electric wine noise caused by irregular +12V voltages. My BIOS reads perfect +12V on idle but CPUID reads very low (around +1V) on idle and around +8 to +11V under load. My rig is plugged in to wall trough a UPS that can handle 800W.

Could it this really be a voltage issue? Should I RMA my video card (it would take so long to have it back since I`m in Brazil)?

 

May just be "normal" coil whine under stress my card does it some times.

 

Try Aida 64 and watch your 12v rail idle and full load

 

Put putty around the area of your noise and try a different power supply.

 

I thought it could be normal. But it bothers me so much! LOL

 

+12V seems ok but I will try this software.

 

Ok so I did two 5 minutes Aida 64 tests. First one with GPU stress. It got +12.288 all the tome and the noise started at 1 minute 52 seconds.

Second time I did it WITHOUT GPU stress. The voltage was the same and the noise started at 1 minute 13 seconds. That`s horrible news.

Could this noise be coming from my processor or mobo?

 

Thanks for the help guys. Fortunately I have found the root of the problem by myself. Turns out it was a CPU noise and not GPU. Turning off Intel`s Turbo Boost fixed it for me.

 

You mean the CPU fan was revving up as the CPU temps went up?

 

It might have been that. Either the fan was noisy (I don't think so since it still spins pretty fast) or there was electrical noise on the overheated stressed CPU.
