FILTER AIR COOLED HOOD AND FAN SETUP

Hii guys I've got my tent up and running but having problems with my filter and fan I have a6"rvk150l 760m3/h and 5" rihno pro filter I was thinking of buying a air cooled hood to help lower the Temps to but the problem is that when I put my filter on it stops the fan working properly also my tent is 80x80x160 with a 600 watt hps with my room cold it sits at 25.5 -26.5 and no filter with filter 30+++ any idea if the cool hood will help with Temps
