Question Fan setup for NZTX H700

[alonbl]

I have a NZXT H700 and when I built the system I added 2 more fans (NF-A14 PWM chromax. black) one back and one top and moved the 140mm NZXT fan to the second slot on top.
After some reading I suspect I made a negative airflow. So my question is this airflow is negative/positive/neutral? and if its negative should I reduce the speed of the exhaust fans?
I have NH-D15, RTX 2080ti and i7-9700k both are overclocked so I need good airflow.

I have the same case. I have the 3 included fans on the front, 3 radiator fans as exhaust on the top, and the included 140mm exhaust at the back.


Since you have less fans, I would orient the cooler towards the back, and put the 3 infront as intake, the 140mm at the back and 1 at the top as exhaust.
Should be optimal.

So you suggest I remove one 140mm fan from the top?

ah no, you have 1 more? then just put it on top as exhaust.

That might make it only slightly negative pressure, which is actually good in such a constrained case.


Also
This doesn't matter
What is it
like .3 degree difference?

Sorry Ill write it simply:
There are 3x20mm intake (all in the front) and 3x140mm exhaust (one back two top)
Will it generate more dust?
Should I reduce the exhaust fans speed?

Doesn't matter. This case doesn't easily get filled with dust and has filtered intakes.
For cooling it also doesn't matter. Use all fans in that oriention.

I'm planning to use this airflow, how is it?

Pretty good.
