There's been a lot written about junkyard fans that do the job more than adequately. Ford fans from the early 90's specifically. Off the top of my head, I believe they were the fan from the 3.8 V6 as used in early 90's Taurus models, the dual fan from a little later Cougars (don't remember the exact year or this one, but I know there was a dual fan that people use that's supposed to be good), and then the big one is the Lincoln Mark VIII fan. You can get these all very cheap at a junkyard or brand new ones of most of them from Rockauto even for under $100. Throw in a higher amp alt for the other $100 and there you go. Less than $200 - a lot less if you find one at a junkyard.
