Top outtake fan (I think) makes really loud sound for about 10 seconds.

So I've had my PC for 2-3 months and this only just started to happen. Whenever i start up my PC the next day it always makes a really loud sound on startup, but weirdly only for the one day it does it once and then the next day it does it again. I'm thinking having it plugged into the PSU via molex might be the problem, but it never did this. I'm not extremely worried as i think it is just the top outtake fan but help/insight would be much appreciated.

This also happens to my PC on startup. Does the loud fans keep up the noise continuously or does it die down after around 5 seconds?

That is kinda crazy. Just for the hell of it, I would swap it out with another fan (assuming you have more than one). See what happens then.

Like i said just happens for 10-20 seconds. And then happens the next day.

I don't really have another spare fan.

It should be fine if it isn't continuous. However, if your system starts to overheat, then the fan would really need to be swapped out.
