Question Is this a simple WD-40 fix?

[Dj0gany]

I can hear a rattling noise (sounds like a 1.9tdi) coming from middle and top fan. When i stop the middle and top fan with my finger the noise goes away, so it must be the cooler bearing, right?
Im just wondering if a little bit WD-40 on the bearing would solve it, or some silicone spray, or is there smth else that i should do.
Recently i did a front panel mod on my case (for anyone interested), and the noise is really annoying, since the coolers are pretty much fully exposed, but it was always there since i bought it back in 2019, it was just not nearly as loud as it is now, because the front panel blocked away the noise.

COOLER NOISE

No.
This is a fan replacement.

A squirt of WD-40 may make the noise go away for a little while.
It is not a "fix".

I didnt express myself well, i know it wont be a permanent fix, im planning on buying a new case in autumn (with new fans included), so my question would be is it safe to use wd 40 (or something else) on fan bearings as a current "fix", until i buy a new case/fans, which would be approximately 2-3 months?

A squirt of WD-40 may make it worse in a week or two.
Or mask it for several months.

New noise from a fan is a result of worn bearing surface.

I understand what you are saying, but i cant really afford a new set of fans currently, and i cant be bothered to listen to the rattling sound anymore, so i think i will roll the dice and spray a bit of wd-40 on the bearings, btw some google searches are suggesting that i use silicone spray, and not wd-40, i have little knowledge of which is which and which one should i use?

WD-40 is for water displacement. In other words it will likely push out any grease that is remaining in there. You might be better off with white lithium grease or a little bit of sewing machine oil.

The better option is replace the fan. You might check on eBay, sometimes you can get sets of case fans from overseas for cheap.
