Case Fan Help

[weggie]

Hi Guys,

Thanks to you guys I finally built my ideal Gaming PC, Im gonna need help from you guys one more time. I Bought a Fractal Core 3000 case

http://www.newegg.com/Product/Product.aspx?Item=N82E16811352010

It comes with 3 case fans, I bought an additional 4, heres how the fans are placed

2x 140mm top - Intake
2x Front 140mm and 120mm - Intake
1x 120mm back - exhaust
1x 120mm bottom - Intake
1x 120mm side - Intake

Is the fan placement optimal? Or should move switch some of the fans around?

too many intakes

top fans usually exhaust--as hot air naturally rises the fans exhaust it out

+1. And I should add that I am not a fan of side fans. My tests showed GAINS in temp for everything except the northbridge (The northbridge is right by the side fan). This was with all fans on high, including the side fan. I believe that the side fan should be a LOW flow fan! the side fan's purpose is just to keep the flow close to the mobo, I think. I have a low flow fan in the mail, and will run some more tests to be sure. You can run some tests with and without the side fan for yourself if you want. If you have a low flow fan, put that one on the side.

Thanks for the replies, I think the side fan is low flow as it doesnt suck too much air. I'll do that test you suggested. Ill report back once I get home (provided work doesnt kill me lolz)

I think the front and side fans are meant to blow cool air onto the motherboard and its components. and the rear and top fans suck hot air out.
