Hi there,
I need to replace the fan in my LC III with something silent. It has a 3 pin connector to the mobo. Will any 50mm 3-pin modern fan work?
Im looking at this one for example: https://www.steg-electronics.ch/fr/article/Fractal-Design-Silent-Series-R3-50mm-19940452.aspx
Thanks in advance!

AFAIK, most 3-pin fans will work, barring any strange specs. As long as it's a 12V fan and the W rating is less-than or equal to the original, you should be fine.
Also fan height/thickness is another factor (something I'm currently working through with a couple of my desktops) e.g. I really want to use some 80mm Noctua fans in a couple of my Macs, but many of their fans are 25mm, and will cut into space used by drive connectors and so on.
But in your case, I think you've got it correct with the fan you linked. I don't recall what the LC series fans dimensions were.

Thanks for the quick answer!
The original fan dimensions are 60x60x15mm. The one I linked to is 50x50x10, and I just understood the external dimensions of the fan are given, and not the distance between the mounting holes. So I just bought a 3-pin 60x60x25 fan. The thickness shouldn’t be a factor, as long as I find a way to secure the fan to the case, since the original tabs will be to short.

It might be an issue, depending on the clearance between the fan and the lid of the case—it might provide reduced airflow as a result, but not having one of those in front of me I can't say for certain.

There's enough clearance, that shouldn't be an issue. Airflow might be reduced, but I'll have to try! I was mostly asking about the 3 pin connector.
