New to HPS need help

I went out and got 3x6 in inline fans, i attached one directly to an end of my easycool6 reflector and then put ducting from that blowing out of the tent.
I then installed 2x6 in on the 2 bottom front holes and i am still getting about a 90 F temperature and they are just seedlings, might be too late for them im hoping but i need it cooler, i am working in a basement as well.
PLEASE HELP!! Also i have been keeping my 400 W Metal Halide a foot away from them, i even tried raising it to know temp change.
