Honda generator enclosure fan question

I am putting my Honda EU2000i in an aluminum truck type tool box on the rear of my Toyota. I would like to be able to run it with the box closed. I have most of it figured out, wiring, exhaust and such. But am not sure of what to do for fan for drawing heat from box. I have done several search's and not finding what I am looking for online.

What I would like to do is use 3 120mm computer/case fans that are capable of moving 70 CFM each for a total of 210 CFM. Bad/good idea?

Most of what I see are using electric automotive radiator fans, which many say they are using a rheostat to run the fan at slower speeds. Those fans to me seem capable of moving waaaay too much air for this purpose unless governed down. Just trying to remove heat from box, not freeze it.

Any thoughts, ideas, links, input, wisdom, criticism or wisecracks greatly appreciated.
  • I have an aluminum tool box on the back of my trailer.
    I have the end of each generator that blows exhaust and hot air pointed out the ends of the box (holes are cut out).
    For fresh air, I have a couple of rectangular louvered vent covers (building supply) mounted on the front facing side of the box.
    Tie down straps for each generator inside the box.
    Also, have plywood floor with round cutouts for the rubber feet on the generators.
    I have a custom made (by me) tarp for the tool box.
    Seems to work ok.

    Also, I used rubber vibration reducing spacers to reduce vibration.
  • I would think that two computer fans would work great. One pushing air in and the other one pulling air out.
