Hey everyone, I am putting the pieces together for my grow and I can get my hands on this fan http://www.canfilters.com/fan_metal_rs12.html (the rs12) for a good price. Perhaps a $100 or less. Now I know from a volume standpoint that it is overkill and not required for my setup but I know that a speed controller can set it up to the speed that I want. Now what I am really looking to understand is the noise that it will make. Would I be better off getting a stealth fan (as the reduced sound is my priority) or would the fan above be sufficient at its reduced speed?
