I just installed these fans a few days ago and my controller just couldn't handle the amp draw. My controller was this one.

Now, I need a beefier controller and I was looking at a couple different ones. The first link is a Derale single fan controller (non-adjustable). Would a couple of these be fine? The second link is a flex-a-lite variable speed controller I was also considering. My question with this one is, would I need relays for it or can I just wire it directly to the fans?

Thanks for the input.

Make your own controller for 30 and it will be better then any of those, look for pat's wireing diagram on his efan thread

 

This one is more that 30 bucks, but high quality and programable.

azmidget91, can you elaborate on pat's efan thread. Who's pat and is that his screen name? Where do I find his thread?
