This may well be a stupid question but I'll go for it anyway haha.

I have a Corsair 750D, I've set it up to maintain positive pressure and try and keep dust out. As such I have 4 Alpenfohn WB2 140mm fans as intakes - 2 in front, 1 in the bottom and 1 at the upper rear of the case.

I have 3 Parvum F1 120mm fans pulling air through a rad to exhaust out the top, now it occured to me that I'm cooling the rad with warm air from the case and it will be more effective pushing cool air from outside the case through it.

Am I likely to cause air flow / stagnant areas by having the 3 rad fans inputting air, the 2 front and 1 base fans inputting air and one single fan at the top back exhausting?

Cheers

Tried it the other way around, idle temperatures were cooler by a couple of degrees including the water but under full load it actually got hotter by a couple of degrees. Took a bit longer to get up to temperature but not by much.

The air flow noise was definitely louder though so I think I'll be swapping it back again.
