Help with case hair cooling

[jazrath]

I bought bitfenix prodigy midnight black case. I cant decide how to air cool it. My thought was 2 120 in front. 2 120 on top. 1 140 on rear. And maybe one 120 on bottom. Would this work or is it to much? Intake will be top and front. Rest be  exhaust

I'd advise against using the top as intake. You'd be better off leaving the top as an exhaust as hot air rises naturally anyway.

The rate that heat rises is so slow compared to even the lowest CFM fans that it is negligible.

 

For an air cooled solution, using the front top as an exhaust will result in worse thermals because the fresh air from the front will be exhausted before reaching the CPU cooler.

So what would be your recommendation on setup for fans?

When compared to a fan, hot air won't move at all. See GN's videos on cases.

 

I'd get a AP182 for the front as intake, and use the included fans as outtake

What would your recommendation for case fan be for the case?

Everything intake, back exhaust

Using the top as intake and rear as exhaust would be good. Although not necessary, extra fans at the front for exhaust would be good for extra cooling.

Where are you shopping / located? Budget?

The cpu cooler blows downwards at the motherboard so top intake would help supply it air and not fight the airflow. The cpu fan could be mounted to exhaust towards the top but the fan blades would probably be noisier in pull on the heatsink. The graphics card cooler acts as an intake and the heatsink fins are oriented to exhaust air towards the front and rear of the case. Since the top and side are intake, all that's left is to use the rear and front of the case as an exhaust.

Shopping on Amazon and 1200 bucks is my budget before tax and any shipping.

So shopping in the US?

If you don't already have the components, I'd probably recommend some different parts. The NH-L9x65 isn't very good when you can fit a larger cooler and the Prodigy is a pretty outdated case design.

I like the design and look of prodigy. I bought the case already. Yes I live in USA. I have not  bought CPU cooler but since it a mini itx build I did not want put to big of cooler on. I want stick with noctua for all fans and CPU cooler. I know there good. I can change CPU cooler If you recommend one and tell me why.

The Prodigy is pretty big and has plenty of room for a large cooler. Despite being itx, it has a footprint that's as large or larger than many atx mid towers.

Are you oc'ing? Why stick to Noctua in particular?

Heat rises, but dust collects quickly if it sucks in air. Linus did a test earlier this year I believe where they tried "all in", "all out" and "thru" type configurations.

 

Suffice it to say, DUST magnet for "in" fans.

 

 

The thru setup, or more typical setup, results in a lot of dust concentrated on the filters, so "intake" fans should be filters, but also cleaned more often. The "outy" (all out) configuration resulted in dust collecting on every hole in the chassis, and then collecting on the inside of filters of the "out" fans.

 

So in a nutshell, if the chasis has a filter for that fan, that should be an intake fan, otherwise it should be an out fan.

Thanks so much. The bitfenix prodigy midnight black has filters for top front and bottom fan. But not rear. I know positive pressure is when you have more coming in then being exhaust. An that typically what you want with fan cooling.
