Computer hardware issue

Don't try to vaccum it out. Just get a can of compressed air from a hardware store and use that. Blow jobs >>>>>> suck jobs.

When temps reach a certain point modern fans usually kick into a high-RPM mode. If you had used the computer in the past for really-intensive things (finalizing an edited video and outputing for an hour straight) it would do that. Simple fact is you've never used it heavy enough, it's always been capable of doing that. At this point, it's just from all the dust. Also don't be afraid, it's not going to shock you. Just touch the case to ground yourself before touching any components so you don't shock anything inside with static, but otherwise it's 100% safe.

Last tip: You probably should insert something like a ball-point pen into a fan before blowing it directly out - to block the blades, so you don't temporarily turn a 100rpm fan into a 2000rpm fan.

ETA - last note: They don't get dusty by being near something, because of their nature, they act like giant air filters and often statically attract dust whenever they are on. Even in a super-clean tile-floor, no pets house, they'll still be crazy full of dust in that timeframe.
