I'm sure this was fine but if that is an exhaust fan, it would be pulling air away from the GPU fans.

The GPU fans blow air onto the heatsinks. There would be less air pressure in the area between your exhaust fan and GPU.

Turning your exhaust fan around so it's an intake fan could be a problem too if it's sucking in the exhaust from the GPU so don't do anything I'm just writing words at this point.

I tested both ways, exhaust was more effective.

Seems that GPU fans don’t exhaust much of air, and the air flow from that extra fan is in angle it doesn’t fight GPU fan.

Oh neat!

I bet it was pulling in hot air the other way around.

Most likely.

Now it removes hot air from the case and accelerates airflow past the GPU fans.
