Btw, about the

smaller (but more powerful and jet-engine loud) exhaust-style coolers.

Why not make double-sided racks with fans twice the size, higher cooling efficiency?

Not sure exactly what you're asking, but usually servers are built in a way that several units can be stacked on top of each other in a rack, which makes it important that air comes in from the front and exits from the back. The smaller coolers then allow you to cram more GPUs next to each other since the higher heat density won't matter due to the airflow speed inside the case.
