Fan Directiions?

[captain204mike]

i have 2-80mm fans in front of case
1-80mm fan in top of case
and 1-120mm fan in back of case

which way should i put these fans to get best air,,blowing in or out?

i would say to have the 2 front 80mm fans as intake
and the back 120mm as exhaust
dont know about the one on top though

I'd have the top one blowing out. Might as well give convection a little help.

2 front intake
2 back exhaust
1 top exhaust (hot air travels upwards)

2 front intake
2 back exhaust
1 top exhaust (hot air travels upwards)

That's how I would do it too.

He has only 1 back fan.

120mm intake
1x80mm top exhaust - Cycle air past the CPU fast.

2x80mm exhaust - Create a negative pressure zone within the case, I think this will help draw more air through the intake fan in the back.

- Trade off is more air = more dust. Personally I use positive pressure to limit dust in my case. It works.

Ok here is a question on the subject. would a 120 mm fan be better as an intake or exhaust if its going to be positioned next to a zalman heatsink/fan.
