Fan controller makes fan buzz - Is it normal?

[mellorbo]

hi guys,
i have a 6" 150mm ram extraction fan HydroGarden | RAM | Inline Duct Fans

with a smscom fan controller and thermostat
SMSCOM Fan speed controller 6.5 Amp

the issue im having is when i plug the fan into the controller the fan makes a buzzing / hummmmm noise even on max.
im wanting to turn the fan down to 1/2 - 2/3 lower as my girls are in a tent (1.2m x 1.2m x 1.8m) in my pc gaming room and fans are in here with me and its hard to game with the noise (if i have no choice my girls come first)
i know the fan is overkill but i got it 1/2 price and its also connected to my 600w hps air cooled hood... i have a 4" 100mm cold air inlet plus 2 passive filtered inlets

this is my first grow and im paranoid as hell. what i want to know is if its a fire hazard. or a danger in any way. i mean a dimmer switch on my house light bulb buzzes but is it the same?

sorry if this is long winded but im super medicated atm

all and any help is greatly appreciated

I think the problem is the cheap fan controller I paid 250 bucks for a fan controller no noise ,smooth and silent it's a smscom hybrid controller with 3 dials to control temperature and fan speed, I've wasted a lot of money on cheap crap , see if you can return it and buy a better one
