Noisy Powerhead

[dwezil20]

I recently purchased two Rio 180 powerheads to help circulate my 80 gallon tank. When I hooked them up I notice they make a small humming noise. It’s similar to the humming of a mid priced air pump. My questions is do all powerheads make this noise or is it just the lower costing powerheads. The tank is located in my bedroom so I would like to keep it as quiet as possible. Any advice is appreciated.

With the few no name brand powerheads i've used they didnt make much noise at all when fully submersed. Maybe I just didnt notice it but I probably would've if it was noisy. I would make sure they're fully emersed in water, I know it sounds silly but you never know.
