Flex-A-Lite electric fan Reply #15 – January 16, 2007, 10:37:22 PM I like my Taurus fan, I feel confident that my engine is nice and cool. Really does need a decent fan controller though, I went for a cheap one and it melted the wires Quote Selected

Flex-A-Lite electric fan Reply #17 – January 17, 2007, 03:20:08 PM Quote from: JeremyB;124199Actually, the early MKVIII fans flow better than the later fans. I can't remember the year they changed the blades though. Later MKVIII fans shared blades with the MN12 fans.IIRC, the Mark VIII fans are in no way identical to the MN12 e-fans. The MN12 fan is a two speed fan, while the MarkVIII is a computer controlled, variable speed fan. The Mark VIII blades will not bolt up to the MN12 fan motor.Unless you do some fancy stuff, when you hook up a Mark VIII fan with a regular fan controller, the fan is no longer variable speed, and is all on all the time (at least when the switch turns it on). That fan will suck small children, Crystal, and Weasle up against your grill.And according to folks at TCCoA, the 98 fan is the best one. Quote Selected

Flex-A-Lite electric fan Reply #20 – January 18, 2007, 01:30:04 AM what's required as far as input from the computer to run the mark fan? mark puter, or will the t-bird/cougar puter work? Quote Selected
Flex-A-Lite electric fan Reply #21 – January 18, 2007, 03:29:42 AM Nothing from the computer. You need to make or buy your own controller, variable speed or not. Quote Selected

The internets also agree with you. :hick:I spent a while searching for Mark VIII fan posts, and ended up with nothing but contradictory information. A few posts say the older (93-96) fan outflowed the later fans. (1)(2)(3)Other posts said the later fans outflowed the earlier fans, or that they all flowed the same (1)(2)Some posts said the MKVIII and MN12 fans were the exact same except for the motor. Others disagreed. (1)(2)(3)Heck, I found a post or two saying the 93-96 fans were 2-speed, but the later fans were 1-speed. (1)I think the '98 fan is 'best' is because it is the cheapest when bought new, not that it is superior to the other fans performance-wise. Quote Selected
Flex-A-Lite electric fan Reply #24 – January 18, 2007, 12:31:26 PM From the thread I posted above: QuoteThe truth about '94-95 (maybe up to '97) MN12 E-fan and the '93-'96 M8 fan.. Since i have both, right next to each toher... Just looking at them, they do look the same.. but the connections are the same plugs, but the M8 is only ONE speed, where as the MN12 one is TWO speed... The M8 fan out pulls the MN12 on high.. The shroud IS the same.. The fans blades ARE the same.. The motors are different; F3LU-8K621-AA for the M8, F4SH-8K621-AA for the MN12Oh and the motor and blades are MADE IN CANADA !! Also i Believe the M8 Fan is orginally Bi-wired on the postive side.. i've hooked it up that way for testing, and the 12Ga wiring i was using as a test never got hot, nor the connectors... Also it's how it's wired in a M8.. Quote Selected
