All better. It's a 10 ohm resistor. With pwm1 at 0, the fan spins but it does go faster at 255. I guess that'll do! Big Grin

Spoke too soon. Looks like Q2110 was hanging on for dear life and after some time, the base no longer bases and the collector-emitter is just a diode now. The fan spins all the time, which is OK. I've added replacement components to the BOM of a future order.

Marked as resolved - Leaving this here on the lottery chance anyone else got a board with the same defect.
