Anyone run any of these? I hear both are great for crawlers that run warm. From what I can find the lincoln fan draws much more air? I have a flex-a-lite electric fan w/shroud now thats around 2000cfm. Doesnt do to bad, around 190, until long inclines or hillclimbs, then I sometimes jump up to 230. Running a griffin aluminum radiator, e-fan, and a 160 tstat.
