Humming noise / fan noise when turned on

[Lai C]

I've had my Fujufilm XT200 for almost a year now and it normally doesn't make any noises when I turn it on or use it but the past 2 days, there has been a humming noise or low fan noise coming from the body. I didn't change anything in the settings and I even tried to turn off IS mode to see if thats the problem. I've searched and saw that Fuji's with IBS sometimes has this problem, but to my understanding the XT200 doesn't have IBS. Does anyone have any idea why this noise is happening all of a sudden and is there a way to fix it?

I've been using the same kit lens, 15-45, it came with so I don't think lens would be a factor.
