    Whilst I love the idea of fans just idling along, that is the point that most controllers give up & the fan hums

    Myself, if I go much less than 50% then I get hum - but that's on a 5" extraction fan... above that, the technology for fans change

    My sms hybrid pro has never hummed, after 3/4 years I got a problem and they took it back and repaired it no problems without registration or receipts.
    It’s been ruining a year since
