airflow in my case

k0enf0rNL

my build is below. I wil be getting a fancontroller too. What do you recommend for my h100i? exhaust or intake? and push/pull? if i put it as exhaust i will have negative airpressure. if i put it as intake i will have positive airpressure. but then the only exhaust will be the 140mm fan at the back.

i will put 1 140mm at the back 2 120mm at the h100i 2 140mm as intake in the gront and 1 120mm as intake in the bottom.

Exhaust out on the h100i, intake on the front, outake on the back. Push pull doesn't help much with the h100i because the radiator is so thin.

It doesn't make that much difference to pressure as to where you fit it as intake or exhaust, assuming you will still have the same amount of fans in the case the pressure will be the same... As to where to fit it, this is your preference. I would always go with exhaust but can't really tell you why, other that the fact that if the rad is on the intake then other components passively cooled, as well as your gpu, will suck in hotter air.

EDIT: should've made it clear I was talking in terms of CPU temps only when I said your preference, but for the rest of the system included then exhaust is the only way to go really

Well from the way you described your setup it seems all you can really do is decide where to place the H100i.  Most every build i've seen they have placed it at the top (usually as pull).  Hopefully this pic will help others help you

thanks :) i will be leaving 1 drive cage in so i can use the other space for a 120mm fan. so i will have 3 intake and 3 outtake. i can change it if i want to.
