Ps5 fan not working

I’ve been having an issue with my ps5 fan, I’m currently in my 4th fan replacement. Once I swap the new one in it works fine for 3-4 days then stops working and get a screen saying ps5 shuts off due to over heating. Has anyone had this issue or any idea as to what it may be?

Was the original fan spinning before you changed it?

No it stopped spinning that’s the reason I replaced it
