Tried a reversed fan setup on my NR200 build yesterday

I built my first ITX system in a Cooler Master NR200 about two weeks ago. Stuck with the usual bottom intake, top exhaust layout. But yesterday I flipped all my fans to pull fresh air from the top and push it out the bottom. CPU temps dropped about 6 degrees under load because the GPU wasn't recycling its own hot air up through the radiator. Just weird how going against the conventional wisdom actually worked better here. Anyone else ever mess with nonstandard airflow directions?

Wait you seriously flipped the bottom fans to exhaust? That's wild, I gotta try that.

Oh man, seriously do it! I did the same thing like two months ago and it made a huge difference for me. My GPU temps dropped by like 5-7 degrees after I flipped those bottom fans. It just makes more sense when you think about it, all that hot air pooling down there has to go somewhere. Definitely give it a shot, you'll probably love the results.
