I have 2 6" ecoplus axial fans ( http://www.aquacave.com/eco-plus-6-axial-braquarium-fan-235-cfm-2874.html ) that I'm using to cool my 3x2x3 grow box. These fans are pretty loud and way more power than I need for such a small space so my question is what is the best fan speed controller for these specific fans? From my research I have come across 2 that I like but can not decide. The fan speed controllers are the ok501 ( http://item.mobileweb.ebay.com/viewitem?itemId=130471806577&index=24&nav=SEARCH&nid=56711350324&back=1 ) which is basically a replacement cord for these fans with a speed controller built in. The other is a variable fans speed controller for all ac fans ( http://item.mobileweb.ebay.com/viewitem?itemId=150632428501&index=10&nav=SEARCH&nid=88546824463 ). I am trying to avoid the buzz/humm noise people have told me that fan speed controllers some times make. Any input would be helpful, thanks guys.
