Inviscid AI simulations drop CPU temps by 13C with bottom intake. This challenges the standard front-to-back airflow dogma builders have followed for years. Hot GPU exhaust usually recirculates into the CPU cooler path in typical tower layouts.
Pulling cool air from the floor bypasses that heat trap. Most cases only use bottom vents for power supplies due to dust concerns. Floor fans need serious filter maintenance since they sit closer to carpet debris.
Real-world testing is missing, so take these numbers with a grain of salt. Simulation models might not capture every geometric nuance of actual builds. You need specific case clearance to mount extra fans below the PSU shroud.
