The arrow is on the underside I placed the fan upside down just so that the cable could rap round and keep tidy. Still, it now blows through the headsink and out the back of the case.
I simply placed it the wrong way round to begin with, that's why I went with pull, by accident... haha!
I'm happy with my case and the temperature now. When I invest in improving I'll go that little bigger.
Cheers
