I need help! What fans should I use?

[JTG2003]

I am getting this case:
http://www.newegg.com/Product/Product.aspx?Item=N82E16811119137

It has 7 120/140 fan spots (plus what looks like an 80mm fan on the backside of the motherboard behind the CPU)

1 in the front

1 in the back

2 on the left side (the side that removes, seems to be over the CPU and Video card

1 on the bottom

2 on the top


Should I use 120mm fans or 140mm?

What directions should they go for good airflow?

Thermaltake has 120mm "Smart fans" that will detect temperature and increase fan speed based on the temps.. should I use these?

I'm pretty lost.

Any help is appreciated
Thanks, Jeremy

I got you man. Use the thermaltake smart fans those are really good. I use the 140mm versions in my system. You are going to want 5 of the 7 fans to be intake and the other 2 to be exhaust fans. Your system will run so cool!

yate loons probably the best case fans you can buy(for price to performance ratio)
