Budlightyear did advise me that even tho most controllers can be used below the 50% setting, you shouldn't really let it go that low. I can't remember word for word what he said but any fans running below 50% will be fecked long before any running at 50% and over. On my ecotechnics controller I can set the minimum fan speed, that stays at 50% and I don't really get any hum apart from when it starts after the heater has kicked in. I'm sure all fans him a little when building up speed tho.😉
