Intermittent noise from print fan

Hi,

The print fan on my Prusa i3 MK3S+ is noisy when the printer is first turned on (I guess the fans are spun to check they are ok). When I do a print it makes some more noise when it first starts (i.e. after the first layer) but not as loud as on boot, then normally settles down.

Does this need replacement? Could be shot bearings, though it's only had a few hundred hours. Could be debris?

Thanks

Edit: I ran the system diagnostic, the print fan made some noise but passed the test apparently.

Best Answer by Diem:

If it's getting louder, carefully peel back the sticker protecting the centre, add a single drop of light oil and replace the sticker.

Cheerio,

Thanks @diem, that seems to have done the trick. I didn't know fans had little oil wells under the sticker!

They don't ... but that's where the wear is.

Cheerio,
