Hi, I know this question has been asked a thousands times before but I can't find it. My computer temp usually runs at 75 F during normal internet use and up to 84 or 90 F while playing games (depending on the type of games) Today I noticed that my computer was running at 82 F during normal use and since my room was pretty cool; all but a bit of sunlight coming into the room I figured that I had too much dust; so I took off the case and cleaned the fans. But it only made it worst. Now my computer is running at 84 -88 and sometimes 90 F during normal internet use. I think the problem was that the fans spinned during the cleaning which did something for the computer to overheat the way its doing. I have no idea. I was wondering if replacing the fans will solve this problem or is there another problem that caused the over heating. Any suggestions please. Thank you!
