Dave that's a great idea and I thought of that but I would like this fan to come on earlier than the PCM fan. So what I'm trying to do is have a fail safe to keep temps lower by having the fans come on at different temps as well as not having a large load coming on when both fans come on at the same time. I hope that makes sense.
