Electric fan controller

I'm thinking about going to the junkyard this week and pulling a set of windstorm fans. What is a good fan controller I should look for while I'm out there? I see most guys either make one up themselves or just fork over the $200 for a really nice one but I figure I can get one while I'm getting the fans.

Managed to get it on the road and moving fast enough after that that the engine was happy but still not something you ever want to have happen.

A standalone controller for an electric fan can be a difficult find in the junkyard. Typically, this function is built into your engine management system.

The old school way was to use a thermal switch of the type used in appliances. They were mechanical in nature and had a capillary tube that you would insert into your radiator fins. Certainly not a $200 solution, much cheaper when you use something like this.

I read about someone using the fan controller off a Volvo 850 with a temp sensor off a vmw e39. Maybe that will be a good setup

The Ron Francis Fan controller works great. Comes with every thing you need in the kit. Here is a link for the conversion I did.

I'm working on installing a controller from DC Controls. Go to their website and read about it. This guy is sharp and knows what he is talking about.

Yes they are expensive, but there is nothing else like them in the world. I just finished my install today and I am pleased beyond words. Here's a couple of quick pics.
