Is this adequate cooling

[AlexSaff]

I will be building a new rendering PC and since it is rendering the whole system will be under 86-95% load. My case is a fractal r5 which has two 140mm front mounts, one rear mount, 3 top mounts (which is where I will be putting my h100i), and 2 or 3 bottom mounts (all 140mm/120mm mounts). I just don't know how many fans and where to put them. Anyone have advice?

That is a lot of fans....unless you are oc'ing the CPU, GPU and RAM, you won't need all of them....I would suggest 1 top fan, 2 side and 1 rear mount to start....if you are running hot, add a fan. It won't hurt having too many fans - but it can make a lot of noise....

Two 140mm intake fans should do the job.
To get positive pressure, you want more intake than exhaust.
That keeps your pc cleaner by filtering all the incoming air.

With a liquid cpu cooler, things get complicated.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
What cpu will you be needing to cool?
If you use a i7-4790K, one of the very best rendering processors, you really don't need more than a simple tower type air coooler with a 140mm fan.
