Question for a dumb person:
I opened up my desktop to clean it out with compressed air. I popped out the cpu fan and sprayed it off, and then put it back in.
The fan has four plastic pegs that fix it in place, and each peg has two plastic pins that click it in. One of the pins on one of the pegs snapped off when trying to put it back, but it's otherwise firmly in place. I didn't touch the thermal paste between the fan and the CPU.
So I turn the PC back on and the fan kicks into high gear, with a warning message that the CPU temp is fluctuating between 90 and 100 degrees celsius (the air blowing out is completely cool).
What am I supposed to do here? Does it know the plastic pin is missing or does it need thermal paste or should I quit trying to enjoy life in any capacity?
