I currently have a Corsair H100i V2 in my NZXT m59 (yes its a tight fit) and I currently have my radiator blowing in instead of out and I am wondering what would truly be the best airflow for my case.
I was wondering if this setup was any good.

Thanks.

That is exactly how I have my H100i GTX setup, with the fans sucking air through the radiator. While it is best to have them push air through some cases and hardware force a slight change. You do not want to be blowing hot air into the case, which I believe you said you are doing, because is heats up the rest of the components.

Isn't it negative airflow though?

That's a standard setup. Tried and true. Can you put two high airflow fans in the front? It's not required. My thoughts are if the case is filtered. All those fans exhausting air will create a low pressure situation. Drawing in dusty air through every crevice.

A negative pressure is caused by more airflow trying to exit the case than is being put in. The downfall to a negative pressure system is that air and dust will be sucked through cracks and crevasses in the case. This leads to the need to clean the case out more often.

You can avoid a negative pressure by adding more air flow in, typically done by adding in high static pressure fans in place of the intake fans to help balance the airflow.

Actually this is not a standard mounting for a radiator. It is best to have the fans push air through the radiator and out of the case. A pull setup is less efficient setup due to the air gaps around the fan. Ideally a Push/Pull setup is best but in some cases, like mine, having the fans in a push configuration will interfere with EPS power wiring forcing a swap in fan position to allow the extra room .

I am going to try a push config for the radiator and I am not too worried about dust because all my intake fans have dust filters and my pc case is elevated off the ground on a wooden box.

If you have animals, I have a cat and my case is on my desk, it finds a way in there. lol it is pain. Filters do help dramatically with the dust and fur that the fans suck in but not what creeps in through the cracks and crevasses.

Give it a shot.

I was referring to the diagram pushing exhaust air out of the case through the radiator. Now that I see it on my computer screen not my phone. I can see the diagram is pulling the air.
