I just noticed this today, and I've never seen it do this: My fan (I'm pretty sure it's my CPU fan otherwise it's my PSU's) keeps going up and down in speed when it needs to go faster, instead of going up at a gradual and smooth increase. I really don't know whats wrong, but if I had to take a guess I'd say it's either the fan controller chip (if there is such a thing
) or the fan itself. Please help, because I don't want it to break while I'm gone and have my CPU over heat.
Like if you pictured a flow chart, instead of it going smoothly up to its desired speed, It goes a little up and down and up and down until it reaches its desired speed. I hope this helped.
