So.. You see , when I leave my PC open all night , the fan goes loud for some reason (CPU Fan) . So uhhh.... any way to fix it without replacing the whole fan?

When you say..."when I leave my PC open all night"...do you mean 'ON'?

Yeah

It might be that the fan is more noticeable at night because there is ambient noise around to cover the sound of the fan.

It is a reasonable simple process to replace the heatsink/fan unit on your processor.

But to advise on what ones to go for we would need to know a few details of tour PC. If you know what motherboard you have great, if not make and model of PC should with a little research provide the information.

...Or, just turn the PC off at night...Aah Bliss!

If it is the fan, and not the quietness of your surroundings, then replacing the fan isn't difficult or expensive, if you have the time and expertise.

If a fan is left on 24/7, then the rates of knots these things work at, no wonder they wear out over time?.

It might be worth cleaning the Fan Blades with a stiff brush

Do you mean the fan gets louder at a specific time?

Could be a timed event - defrag - auto-updating anti-virus.

Maybe change the clock by 12hrs just as a test.

Unless it really has to be on all night, shut your PC down and stop wasting electricity.
