Cooling in a Spec-06 case

Hi, I’m putting together a pc within the next week and am trying to figure out the best way to cool my system.

I have the Spec-06 case and a H80i V2 CPU cooler.

I was thinking of putting 2 top side exhaust 120mm fans, 2 front intake 140mm fans and then mounting the h80 at the back as an intake or exhaust. Alternatively I could mount the h80 on the front with 2 other 120 mm fans as intake and then the top and back as exhaust. Thoughts? I’m going to be overclocking so looking for the best cooling solution with what I have. PC will be mounted on top of a desk.

Thanks in advance
