Thanks for the help. I am not unsure if my current temps are good, I am wondering how much more heat the hid puts out! It will have a remote ballast not in the cab, will a 170 cfm fan and cool passive intake air be enough to keep the temps under 80? Just wondering if anyone has any experience with a similar setup. I have tried searching, but either the space is smaller than mine, or they talk about air cooled hoods exclusively.
