Fan config for NZXT H710 with 280mm AIO

1 hour ago, TVwazhere said:

I would keep the back as exhaust. Likely your CPU cooler fans will spin faster or at least push more air at the same RPM due to being larger than the 3-4 120mm at the top and rear. 

 

A rear intake fan would just have it's air sucked up the exhaust top fan without ever have reached anything tho cool (except maybe VRM heatsinks)

Keeping the rear fan as exhaust, would you recommend 280mm (with rad) exhaust on top with 360 intake in front or 280 (with rad) intake in front with 360 exhaust on top?

I am looking at the NZXT H710 case which supports upto 360/280mm fans in front and also on the top. In the rear it supports upto 120/140mm fans.

I am also buying an NZXT X63 280mm AIO, which combined with the 3x120mm front fans and 1x140mm rear fan included with the case makes 6 total fans.

 

But I am confused about what would be the best config for these fans, I have heard that positive pressure is better because it reduces dust buildup. So I am thinking moving the front 360mm fans to the top and putting the AIO in front, so the front 280mm and rear 140mm fans can work and intakes and the top 360mm fans will be exhaust. Will the bigger fans working as intakes and smaller ones being exhausts make it a net positive pressure? What other configs might be better?

Depends on what your temperature priorities are. The rad at the front will give you better CPU temps but will warm your GPU a few degrees. Alternatively, the rad at the top would means the front fans blow cool air into the GPU, which the CPU cooler would suck up and equate to a few degrees warmer for the CPU. 

 

In reality the delta temperature difference (how much it actually changes) is minute, so go with whichever you think placement looks the best or prioritizes temperatures.
