The hum I was talking about was from the fan running to slowly lol speed I've since had a search about and word with the growshop, and seems the SMS shouldn't have the main fan speed control set under 40% for the health of the fans... Also takes a bit of the hum away as well.

Seems like a cheaper version of the expensive mechanical sms controller and cheaper than knocking up one for yourself lol! Looks like the way forward...
Happy new year btw guys!!!
