cooling Help with air flow

[apoKhallipsa]

Hello I have NZXT H5 Flow White with one 120mm fan at the back.. One 120mm fan on bottom crocked for gpu rtx 3070 gaming X oc v2 gigabyte 8gb vram.. Ale and two 120mm fans at the front and my question is... Can I add two more 140mm fans as exhaust on top for more airflow or there will be some problems with pressures thx for answering 

 

Airflow is front to back

What are the fans configuration?
Pressure wise, depends, negative is better for cooling, positive is better for keeping dust out. So the more exhaust, the better the cooling, but you have a bunch of dust pulled in through the gaps. More intake means less dust, but cooling isnt as good.

I have no worries about dust much looking for better cooling at summer

4 fans is already quite good, do you need more fans at all ?

Also consider undervolting that 3070, I did undervolt mine to 160W max.

it won't be a lot difference wether you install a 120 back exhaust or 140 top exhaust.

2x140 top.. Back already have 120

I have overclock that gpu want more performance for the money

A case cooler won't help you much man.

Overclocking is viable but, youd have to win the Silicon lottery for really big performance differences.

Also the two 140 on top as exhaust don't rly make much sense.

You're basically taking in air at the front, it gets to about mid-way through and gets kicked out by the top exhausts.

I'd say maybe put 1 exhaust above the CPU cooler, and that's about it.

Thanks for the advice

You probably can undervolt while overclocking or at least overclock at lower voltages

(undervolting doesn't imply underclocking)

Closing the roof with something would likely help more than fans that just exhaust the fresh air coming in from the front before it hits gpu or cpu cooler.

That is exactly how my Meshify C has been running for a couple of years now. Top sealed off, air moves front to back, just like toilet paper.
