Need help deciding on airflow in the Corsair 750D case.

[MrDare360]

I'm going to be going to Uni later this year so I'm going to be building a new computer once I get there and I've decided on the Corsair 750D as my case. However, this is my first time building a computer and I don't understand how to get the best airflow in my case.

 

This is what I have in mind at the moment:

 

 

However I've been told it may be more efficient to have my H100i act as an exhaust and to add another 120mm fan with a dust filter (As an intake) to the bottom of the case. Furthermore, would it be worth upgrading my front intake fans and my back exhaust fan to something else other than the included fans? I'm going to have 1 drive bay installed so I'd like to get the best airflow possible.

 

Also, this is my computer build if you need it for any information regarding airflow:

EDIT: Also could someone tell me if it would be possible to hook up every fan in my system to the Corsair Link software?

follow the video about airflow

 

the top rear fan should be blow outwards

 

if not you will get a dead cycle at the top rear

Keep positive air pressure with filtered intake fans. Best option in my opinion.

^ This

Im going with a similar fan config as what he mentioned

The rear and toprear fans of my rig are exhaust and the rest are intakes (top front and front 2 fans)

My case maintains positive air pressure at all times, including under load and my 290x runs at max 77 c while overclocked to 1080/1350

I see. Is this any better?

I'm not sure if I can have 1 fan as exhaust and 1 as intake on the H100i. If not should I move the rad closer to the drive bay, have both as intake with an exhaust next to it above the CPU and then ditch the bottom fan?

 

I want to have a positive airflow so less dust settles in the case.

will still cause dead air at the top

 

go for exhaust at the rears only

I see. If I have my H100i as exhaust only then would it be possible to add a fan to the top front to create equal air pressure or is it not worth it?

Here check this out, I went over the 750d
