So i just built my new rig for gaming about 2 weeks ago. It was running perfectly tell tonight, The CPU was getting too hot so i was replacing the fan it came with with another off brand fan. But i had to take it all apart to do it and i decided i did not want to take the motherboard out and i just put the old intel fan back on and just put a household fan next to the computer to keep it cool. anyway so i turn my computer back on and i want to play war thunder so i start playing and i immediately notice it's going way slower then it had been. I thought that was unusual so i decided to run a performance scan and clean up all that junk and that did not work so i try system restore to a couple days ago and that did not help. So i wondered if it was just that game so i tried playing Crusader kings 2 and it was going alot slower too and then tried mount and blade and it was going slow as well. Very confused at what's going on any help would be wonderful.
