How many case fans should I start off with? Specs to follow..

Computer Specs:
-Intel i7-7700K
-GTX 1070
-Asus Z270E Motherboard
-650W PSU
-Cooler Master Hyper D92 CPU Cooler
-Corsair Obsidian 750D Case

This case comes with 3 fans pre-installed. If I'm not doing any overclocking anytime soon, would the 3 included fans plus the CPU cooler suffice?

Yes, that will usually be enough.

If you want, u can install one top exhaust fan. But the case is big and well ventilated, so optional.
