I've got he MCP-650 and I'm getting annoyed with it's semi-high-pitched hum. I'd like to control it's speed with my Nexus Fan Controller but I read at Danger Den that the pump needs at least 18W per channel from the rheobus, whereas the review of my fan controller says it's channels will support from 15W to 18W. Is this cutting it close?

I'm not sure how rheobuses work, and excuse my ignorance, but is 18W the wattage at full speed? Meaning if I turn the dial down it'll go below 18W and mess with the pump from then on?

Do I need to get a new rheobus?
