Glad I converted you to full blown hydro! :-D

No such thing as too much light

, and a 400w hps shouldn't put out THAT much heat, but that doesn't mean you shouldn't ventilate it. A cooltube would work fine. Theres even a thread somewhere about how to build your own easily.

BTW with a DWC setup in such a small cab (width wise anyway), I think your best bet would be a ScrOG grow. Check out august west's scrog for great examples. (he used soil, but its easily adaptable to hydro.

Also, whats the lumen output on your 400w hps? Personally, i'm a huge fan of 4', 54W, T5 High Output fluorescent tubes. (T5HO).
One 4' tube outputs 5,000 lumens. With a readily available 5 bulb fixture, thats 25,000 lumens. Also, you can put them vertically, and even in the center for under and side growth lighting. The best part though, is the cool temp of the fluoros. You can put them about 1" away from the plant with no adverse affects, therefore increasing the available amount of lighting. (each time you double the distance between the plant and light source, the lumen output halves.)
