screws don't have wholes period. Looks to be held in (on the inside of case) but some uhmm....dunno what they are called but are like the plastic things on the back of push pin heatsinks...the things where you squeeze in and push it.
I'm gonna try to remove the fan and see what i can do with it off
okay..i'm ignorant. You pushed and they came out extremely easy/simple.
Anyway: the front of the fan appears to be cracked. I'm sure it was like that shipped but I never noticed it.
Uhm k..took the blades off to where the motor is exposed..it's no longer spinning period.
i'll edit back with pictures.
