150W Hps Cooling? No Fan Duct

if i have a growbox that is:
3 feet tall
1.5 feet deep
2.3 feet wide
How many fans should i put in there i really want to cool the light i drilled holes in one side of the growbox and im thinking about placing atleast 3 more fans in there 2 for intake and 1 exhaust or 1 intake and 2 exhaust idk which one to decide and i was reading and was thinking about getting 120m fans.

I have a 150 sunsystem light but the shitty thing is that the light doesnt have a spot for me to put a fan on there so i have no clue on how to cool that sucker its also on a shelf but that only gets placed in there during flowering other than that its on yoyo hangers how should i go about cooling it easly gets over 90 degrees in there and the light got so hot i cant even touch it

I have a 4" fan i bought at wal-mart that i hang behind the bulb and it blows cool air directly over the bulb, seems to work pretty well for me, i dont really have temp issues and im running a 600w gull wing

well see the thing is it doesent have fan venting on it only has vents and that fucker got so hot i killed my babies yesterday but im going see how hot it gets now that i have drilled holes in it im thinking about putting one of the fans on the side.

Mines a gull wing also, not a vented hood, i just have a fan blowing on the bulb

the 150w HPS is more heat than light, consider going for a big ass cfl, or even your own cfl rack of 3-6 bulbs
