DIY multi-GPU cooling: case airflow tuning drops temps from 80C+ to 68C, no liquid cooling needed
HankYeomans · x · 2026-09-23
The author shares a hands-on cooling tuning story for a multi-GPU build in a Cooler Master case. By arranging airflow precisely where needed, temps fell from 80°C+ to the low 70s and settled at 68°C — with liquid cooling only on the CPU, while the GPUs run fine on air. A useful data point for local multi-GPU deployments.
