Hello.

My GPU is running at 58 degrees idle and 75 degrees in game (GTA V)

Specs:
i7 7700k
gtx 1070 Asus Turbo
16 gb ram
B250-A asus motherboard
Cooler Master CM iii 690 with 240mm fan front, 2x 120mm or 140mm fans top and 120mm fan back. I'm not sure what to do if I shoul get a fan for the bottom so it blows air into gpu or something else.

That one has a reference cooler design. It's not affected by the case cooling.
I don't know if a bottom fan will do much.
