So, ever since i've built my computer, it has always been hot, but only when playing tough games to run, for instance Grand Theft Auto 5. But recently, i have bought a new fan, replacing the old one, because i thought the old one was creating the heat. (It was a very old fan) I also have another fan on my computer next to my graphics card.Well, after putting my new fan in, i noticed that my computer was getting hot, i mean REALLY hot, so I opened the case and felt my graphics card, (Gtx 970 btw) it was searing hot. Litterally when i put my hand on it, it started to burn. And i wasn't even playing a graphics heavy game! The only thing I can guess is something with my other old fan next to the graphics card. But i'm not sure. So can anyone tell me why this is happening and how to fix it? Thanks in advance.
