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!
