i got 4 daystar bout to get two more to make 6 but the problem is it's only a 4in air cooled for the four i have if i add two more and hook up all the air cooled it wouldnt do shit cause it's only a 4in inline original can fan,it's a good fan dont get me wrong but cooling 6 hoods with 4in fan i dont think so, or just give it to my wifes cousin and buy 6 brand new daystar with 8in air cooled, damn i could see it already 8in air cooled thats shit would be no joke the hood would be cold like snow hahahaha thank disrupt86 for advice i think i stick with the daystar
