i am looking to hide my amp under my rear seat delete. maybe a couple other things too.

i want to hook up some computer fans to make sure it stays cool. i really don't know much about them though and am looking for some guidance. 90mm seems to be my max clearance so i am thinking 80mm for wiggle room. well i found a couple fans that seem to move a lot of air for their size.

basic fan

speed controllable fan

as far as i can see with the vantec, there are 3 or possibly 4 wires. power, ground, and a signal wire to watch fan speed. possibly another for?

seems straight forward to wire up but since they are dc, will it be a direct hook up to a hot lead on the car? inverter necessary? can they handle 12-14 volts?

now the silverstone is a little fancier. i would love to have speed control, but i am uncertain how many fans i could hook into one controller? i would rather not have a separate controller for each fan.

also, it has 4 wires coming off of the fan, is that for rpm signal too?

is it better to push air over or pull air out? the setup isn't sealed, the front has a small gap as does the rear and the sides are open so i could cut holes in the sail panels and use that as the exhaust port. my overall setup would be two fans per delete box. ability to control all 4 fan speeds at the same time and to run at the same time when switched on. any and all insite is welcomed and appreciated!

rough sketch

possible fan placements and air flow

also, should i connect power through a relay like normal electric cooling fans?
