i just got one and was wondering how much of perfomance hit would i get if i orient it the wrong way. The manual says to orient the fan horizontal so the air blows from the fan out the back of case. However since i have a horizontal mounting bracket in can only mount it vertical blowing air out the top. The manual says i should snake the bracket between the heat pipes but its not working out, and my poor heatpipes are being all scratched up.
