Computer Airflow

I’m trying to be more paper focused lately and draw through ideas, sketch my thoughts, and really get that side of things going. This is a diagram of fans and my PC case.I recently acquired a new GPU. Since I didn’t get a new CPU, I’m going to need to overclock that so it can keep up (post about that coming soon). Overclocking produces a lot of heat and this new GPU is going to be warm to. I’ve got a few fans spread out in my iTX case and I’m trying to figure out the best airflow. Option 1 seems the best at the moment, but we’ll see after some benchmarks.
