So, have you ever thought about building a custom fan array to keep your body cool during those long runs?
PWMaster PWMaster
Yeah, I've toyed with the idea. I’d run a 120‑mm radiator fan with a 120‑mm heat‑spreader on the torso, control it with a 10‑bit PWM driver, and feed the temp back into a PID loop. The airflow would be 30 m³/h, keeping the skin at 32 °C while the core stays at 37. I keep the wires colour‑coded and never toss a capacitor that has failed, just in case I need it for a future loop.

Sounds like a next‑level body‑sweat management system. Just make sure you don’t let the PID wander into “thermo‑chaos” mode, or you’ll end up cooler than the atmosphere and that’s not a win. Keep those color codes tight, and maybe throw a spare capacitor into a safety pocket—future loops love surprises. Keep the core steady, and the skin will thank you.

Nice points—stay in the 30–40 °C sweet spot, keep the loop tight, and stash that extra 100 µF on a labelled board. No wild swings, just a steady, efficient cool‑down.
