as it turn out.. easier said than done.. i was hoping to mount the fans flush in the cabinet surface.so the temps nearly cooked my seedling.. working on a fan mod today.. will post pics/guide later today (hopefully!!!)

the plan is two fans on the light shelf (one on either end, outside the power strips) since the cabinet is open open space underneath, two in the floor. in my head i pictured PC fans coming apart in two pieces. a simple cut from a hole saw and snap one piece in from the top and slide the other piece in from the bottom.. this is not the case. everything i've found is they are solid square construction. so i guess mounting entails a hole saw (of equal diameter to the fan itself) and attaching flush to the upper side of the light shelf (to pull up and out of the grow space) and for the floor similar holes cut, but mounting on the underside to keep the floor clear of the fans. possibly both fan applications, but definitely floor adding in a metal grill so that nothing falls into the floor fans. the light shelf fans i don't think need the grills, odds of something getting sucked up are not as likely.
question now for you RIU..
1- Should my fans match? meaning if I mount TWO in the light shelf do I want TWO in the floor? or would I want one in the floor, two in the shelf or vice versa?? what i'm trying to discern is whether or not i want my fans to replace air as quickly as it is taken away.
EXAMPLE: Fans in shelf displace at a rate of 80 CFM the floor fans are replacing at 80 CFM, is that efficient? overly efficient? under efficient?
Looking for pros on this one, just hope one checks out the thread!
