Case fans

[Rohanddave]

So I got the cooler master mb511 case, it has 3 front facing fans which were surprisingly fixed as exhaust fans. However I took out the top two and changed the orientation, sadly the bottom most fan does not come off i.e. it does not have screws. It seems to be fixed, any way of removing and changing the orientation?

Are you sure? Those just look like pins. 

Have you tried using a needle nose plyers to remove them?

Can you see the backside of them from in the case? Or would you have to remove the radiator to do that?

 

And are you sure this is backwards?

Typically the exhaust side has the manufactures' information on the exhaust side along with the wire connected to the motor. 

I don't see that here. 

 

An easy way to dummy check, take a piece of paper and hold it close to the fan and see if it gets sucked towards it or gets pushed away.

The fan that is fixed in with pins is in an intake position.  Most fans the side with the supports for the motor is the side the air comes out.

You have turned the upper fans above it into exhaust fans.  If you want them as intakes you need to turn them back around.
