The clutch fan does ok, but there is a lot of air leak around the shroud (required because the engine moves around). I'll install a temp switch into the rad to kick the fan onto the 1st speed and use the stock 2nd speed switch on the thermostat housing. Having the compressor clutch on will turn the fan onto the 1st speed, and the high pressure switch will kick it onto 2nd.
