Something is not right with those temps. There is no way your motherboard can be running at 57 C - unless you have SERIOUS heating issues in your case or the sensor being close to your GFX or misreported. I use EVEREST to monitor my temps. Also 62C idle is too high.
Try getting GPUCaps Viewer and run a Fur Test, with max settings, while monitoring your GFX card temp - if it keeps going up and getting ready to reach 100C stop it right away.
Look for any artifacting or freezing during the testing as well.
Try to find a beter utility and report back with your real motherboard, CPU, and gfx card temps.

Remember when running these tests always keep an eye on the temp and be ready to stop the test as needed -
You might want to try SpeedFAN, it's free, although depending on your setup it might misreport some voltages and some info.
