Attaching extra fans

[Shayansp]

Hi

I have recently found a Old Computer in my house, i opened it up to find a Motherboard cracked in half, now i did notice 2 extra fans (apart from the default one to cool the CPU) there, i detached those and attached them to my PC, and they work, the reason i wan tto know is, i made one suck air in, and one suck air out, now is this wise, or should both suck air in, and one suck air out? the fan that sucks air in is at the front of my PC, and the other is at the back near my default fan,. also, are these fans required?

So basically, i want to know how i should put the fans, or whether they should be there at all.!

Thanks

In general with a standard case you bring cool air into the front lower portion of the case and push hot air out the back of the case.

in most to all cases you should always have the rear and the top fans pulling air out of the case and the front and bottom and if you have it side panel pulling air in. heat rises so you want the rear exhaust and the top exhaust aswell all other fans should be intake

Font/bottom takes air in rear/top push air out.
