I have the single 18 inch blade mark viii fan im going to install onto my mustang. I need a fan controller for this thing because its pulls a crap load of amp on start up and pushes 4600 cfm of air which is complete overkill for my car. I seen DC control but it seems its hard to get it shipped out in a timely matter. So what else do you guys have that can put up with this fan. I was looking at the flex a lite 33054. Is there anything else out there?
