Strange sound of PS3 fan

[ZackGivesFrogs]

Hi guys! I have a PS3 Slim Model ( CECH-2004A ).
Today, the fan ( I guess it's the fan ) suddenly started to do a very strange sound. It isn't that strong sound when fan goes fast for avoid the overheating ( the temperatures of my PS3 are still low ) , but it's a loud sound that, more the fan speed is faster, and more it's loud. So it does this strange sound even if the speed is low, I don't know how to say, it's like the fan isn't spinning very well or it's placed bad. I don't know.
Should I open the PS3 and look for something?

Can you post a video possibly? Not too sure what you mean

Open the PS3 and check for dust.


Or check for some suspicious activity in the Fan SC(System Call)

Ok guys, the sound seems is way lower now, but still a bit present. I'll try to do what you said and also I'll post a video if I can
