Vortex VTX600 6" Powerfan (452 CFM)
- Ventilation (Qty: 1)
While we don't find the Vortex VTX600 (pictured at right) noisy like some of the cheaper brands that exist, you may want to consider the new Vortex S-Line Ultra Quiet series of fans that are even quieter still.
Keep in mind that once the level of noise for a fan drops below a certain level, what you are mostly hearing is air turbulance in the ducts and not the fan itself, so making a fan quieter doesn't always help. It is not uncommon for a fan to run nearly silent in open air (not connected to duct work) but appear to be very noisy once connected, when in fact what you're hearing is air turbulance through the entire system.
