The ThinkPad Edge E330 with H3 firmware uses the non-standard EC fan register block. Without a matching quirk, thinkpad_acpi reads the legacy tachometer registers and reports 0 RPM. Add the H3 BIOS family to TPACPI_FAN_NS so the driver reads the fan period from EC register 0x95 using the existing non-standard reporting path. Tested on a ThinkPad Edge E330 with BIOS H3ET77WW and EC H3EC35WW.
