As the title says, my case have a fan at the back for the CPU zone to throw away air out of the case.
When i turn it just a little with my fingers, it starts working again for some time.
I've tried years ago to open it and repair it, but I think i remember that I couldn't fully open the fan.
So, anyone knows what happens with this kind of trouble in a fan?
Oh, and I tried to connect it with all my different molex and I think even with only that fan connected. (case have that fan + 3 more)

That fan, sadly, has actually never worked properly from the beggining. I asked to only RMA the cooler but i would had to RMA the case. It's/was very, very cheap "gaming-like" case, and i would had to travel like 1 hour in public transport with this heavy stuff, so, as i like to have the case opened, specially this cheap case with transparent side made of plastic, i kinda delayed-finally decided to stay like this.

try to open it,find different ways and lubricate it with oil.Just a little drop should do the job.
