I always have my top fans as intakes as well. Always has performed better for me.

Same, top as intake. you want the coldest air going threw your rad and pre heated case air isn't the best.

I tend to exhaust out the bottom, hot air does rise but it takes little to no effort to push that air where ever you want.

Yep same here.....6 fans push / pull "intake"...also 3 fans front intake...1 fan top back 140mm exhaust....for me its counter productive to blow warm air over a Rad to cool CPU....also as intake you provide air blowing onto your Mobo, Chipset and Ram....

Positive Pressure works best for me...keeps my CPU OC in check as well as my 3 GPU's happy....wayyy less dust as well....

Quote:
Air IN from the front,bottom [if there's an opening],side [if there is one],and OUT,or exhaust through the rear and top of the case. Every one of the "botique" high end builders recommend that configuration.Google that info and I'm sure you will see the vast majority of enthusiast rigs are designed that way.
^^^^ Nope...its actually split closer to the middle 50 / 50...the intake / exhaust argument as positive pressure vs negative pressure has always been a personal choice and arguments in either arrangement.

Enaberif nailed it.....equal intake and exhaust means neither positive nor negative pressure......imo most case have enough natural vents and seams etc that positve pressure effectively forces air out these vents...with good positive pressure try holding a tissue to a vent on the back of your case.....see the air being forced out?!

Generally a positive pressure environment is gonna be better IMO. Not sure why I never considered reversing the rad though as it makes perfect sense. This is how we cool our vehicles and makes a for a interesting idea to perhaps add 140mm to the top of a case above a mobo and turn the rad on it's side. Be a big assed case tho. :-)

Gonna be switching out the stock Corsair Fans that came with the 900D with 4 x Silverstone Penetrators......fvck, sounds like porn!!!! All 1500 RPM Intakes w blue LED's.

The Noctua NF F Series are great for push / pull on the Rad, very effective.

The top back 140mm exhaust (Stock Corsair), I'm swapping out with a Gelid Wing 140mm with blue LED.
