Taming a jet-engine local AI server with the motherboard's built-in BMC out-of-band fan control
HankYeomans · x · 2026-09-04
The author discovered that modern motherboards ship with a full BMC out-of-band interface, letting you change hardware settings like fan curves outside the OS. Some of his fans were pinned at 100% and made his room sound like a datacenter; after tuning via BMC, the noise only kicks in under heavy load. A practical, non-obvious tip for anyone running local inference/training rigs.
