Ive got a 1200 case coming and it has the big boy fan on the top. i was wondering should i mount my mega halem vertically, so my ultra kaze 2k is pushing air towards it? would it decrease temps as apposed to mounting it horizontally?

The temps would be pretty close.

If you were mounting it vertically, it would be pushing towards the back of the case. I have mine mounted vertically but be warned that you will have to but quite a bit of the corner off of your side panel fan for it to fit.
