Not to long ago I had no problem playing games with really low temps but now I just get high temps playing the most simplistic of games. Im using Open Hardware Monitor to monitor my temps and im getting up to 80 C aftermabey 30 minutes of Day of Imfamy. Is this a faulty Motherboard or something I can fix on my own. Thanks!

80c for what?
The motherboard, cpu?

A faulty mobo is very unlikely to cause high temps for anything.
If it's the cpu that's hot, I'd check fans and heatsink. Make sure they're all working and seated properly.

80c for the motherboard not the CPU. The CPU is fine in temps but the motherboard heats up like an oven
