Do I need my rear exhaust fan? I am water cooling a 6700k and a GTX 1080 with a 360mm rad in the top of my case exhausting air and a 120mm rad on the bottom pulling in air. I also have 3 140mm intakes on the front of my case, the problem is - I can't get the fittings in the top radiatior with the rear exhaust fan installed. Is the rear exhaust fan necessary with this setup?
 
All air that comes in will exit somewhere; you are good.

FWIW, a 14nm i7-6700K does not need exotic cooling. A simple tower type cooler with a 120 or 140mm fan will be simpler and do the job.

And... the GTX1080 is already a very strong card at stock.
Do you really hope to get enough extra fps out of liquid cooling to matter?

Well as I already have the parts to water-cool both the CPU and the GPU its worth water-cooling the build, I'm not a builder for a high performing PC that looks bad.. although I would use that - I would rather that my build look amazing and also perform the same, the enthusiast builder if you will..

I already have all of my fans.. the problem is that with the rear exhaust fan, I can only use 4 screws in the 360mm radiator in the top of the case. would it be okay if I removed one of the 140mm intakes on the front of the case so that the fan setup would be - 2x 140mm and 1x 120mm as intakes and 3x 120mm and 1x140mm and exhausts? with this set up there would be 153cfm of air coming into my case, and 220cfm of air leaving my case.. That means that my case would be in a negative pressure zone. As long as the 4 screws holding up the rad. can support the weight of the fans, water-cooling fluid, fittings, and tubing then I'll keep all of the front fans and just mount the radiator where it is now..

The system is very quite, I'm using EK-Vardar fans, and yes I need them all to accomplish a positive air pressure in the case, the intakes are bringing in 244cfm of air and the exhaust are pushing out 220cfm of air.. with all 8 fans running at full speed you can hardly hear them.
