Recieved my RUCK 125 5" extraction fan and filter today to go in a DR100 1X1X2M tent with a 400w grolux light. Problem is I hugely underestimated the noise of this beast its extremly loud and possibly overkill with 295m3/hour, I sleep in the same room as the tent. Would a ''POWER REGULATOR, ELECTRIC SPEED CONTROLLER (Variac)'' from a popular auction site be sufficient to turn this down to about 1/3 of its power? Thanks
