Low speed, the taurus does 2500-2800, in there. Hi speed, 4500. This as per Gojeep. I am reading
another link right now claiming the Taurus measured 2800 on low and 5600 on High using battery power, 6200 on high running off alternator. That's a lot higher than most of the numbers I see other places online, so, grain of salt.
I'll say, though, that people make a lot of power in Volvos (no, really. They do) without overheating, Volvos using the same fans as the Taurus. I'd think the stock AC fan + Taurus fan,
like here, would do the job.
