Does anyone have an experience using one of these fans, particularly the TD-100? I've read that it isn't loud but the air coming out can be. I've got a small stealth grow of about 6ft H x 2ft deep x 1.5ft wide. Would this fan work well with a 250w/400w hps light and a carbon filter?
If the TD100 is the 4" fan i have one of those. Fan is relatively quiet, but as you said the velocity of the air rushing out makes some noise. I ended up with a 6" centrifuge fan with a speed controller and its way quieter and moves 4x the air...
