[Question] Is top exhaust fan configuration provides better cooling than rear?

Imgur

Hello members,

Is there a noticeable difference in cooling between an exahust fan on the rear of the case vs a fan or two on the top of the case? Would two fans on the top on the case be worse, better or the same as one fan on the back?

Not really. Heat tends to rise to the top of the case, and some case layouts benefit quite a bit from having a fan at the top. It really depends on the individual case though.
