Fan's for the Radiator (Exhaust vs Intake)

I have an H110i GTX and I am going to be mounting it in a 750D. I am wondering if I should be mounting it with it as exhaust or intake as the manual says.

Exhaust would allow the 2 140's in the front and added 120 (noctua NFF/Corsair quiet HSP) in the bottom and a 140 in the rear for exhaust to allow for a negative pressure.

I was going to mount it in a push (mount the fans under the rad in the case) vs a pull, but I kind of like the look of the pull.

I have in my current rig a Kuhler 920 as a push/pull exhaust and it has worked very well for the last 3 years. Any reason why I shouldn't be going with the setup I have laid out?

If you are attaching it to that 2600k it probably wont make much difference as far as cpu temps go. Hell I only run one fan on my h110 (pull exhaust, top mount) on a 4.5ghz 1.3v haswell-e and it makes little to no difference as far as temps go when gaming....

played with a few setups on my rig and determined pull top mount exhaust worked the best for me.

I've heard that positive case pressure helps prevent dust buildup. Otherwise, I don't think it'll matter much.

I always mount mine as intakes. I prefer the positive case pressure. And my vid card exhausts in to the case so I'd rather have cooler air going over the radiator.

Exhaust. Intake fans on the rad are more noisy too. You can`t go against convection (hot air rising) so best to obey the laws of physics!

Actually, you can, and quite easily I might add.
