Can I shut this fan up?

This is the culpret for all my noise problems





If I jam my finger in it the case is almost silent. Is this fan really nesassery? (oops spelling) can I relocate the fan to the back or will that not make it any
quieter for me?



The fan box is a bad design its touching the PSU (look )

Ok I'll probably go for a replacement fan or two, two would be quieter than this beast, I'll maybe put one on the intake

and the side panel an exhaust though it will probably be blowing in my face
