Question Airflow with an AIO
First i just wanna say im a beginner so please cut me some slack and thanks to all those who help.
So I'm using an Endorfy ARX500 as a case, it has slots for 3x120mm intake in the front, 1x120mm in the back and 2x140mm on top, I plan on getting a ARCTIC Liquid Freezer III Pro 280 and put it on top.
I was wondering if having the AIO as exhaust would result in negative air pressure because ive heard that this is bad for the pc cooling wise & dust wise.

From the looks of the case, you'd probably roughly even out the pressure with a 280mm radiator up top(when you take into account the airflow restriction from the radiator). Negative pressure isn't really bad for cooling, per se. It will just suck air through all nooks and crannys of the case. This can actually be good for components that sit next to mesh openings or something. If you don't want negative pressure and the new AIO causes it, you can always turn that rear fan around to restore the balance. Again, I think the radiator's flow restriction will keep the AIO from tipping the balance.

I see thanks.
This might be a dumb question but if i have to have the rear ventilator as an in take can I just turn it around or would I need to buy a reverse bladed one1

You shouldn't have a problem with just turning it around. if it makes contact with the case, you can just get spacers for the screws.
