My beloved 2013 iMac seemed to have a weird, wonky issue with its fan, where it would spontaneously spike in speed at random intervals. Like, out of nowhere the fans would ramp up to high speed for a split second.
Some Googling suggests that it could be dust or gunk slowing down/clogging up the fans, so I took my house vacuum and vacuumed both the back and bottom vents, hoping to suck out any dust or debris that might be inhibiting the fans. We'll see what happens. I'm not relishing reopening my iMac to replace the main fan.
