So I may just have the fan running all the time... or, I guess I could deal with a relay at some point so it'll only run when the heating or cooling relays are on.
I think the latter may still give the same problem as I have now though.
One thing to note though is that I still have the temp probe in free air, so it's probably affecting the differential a lot more than it will when I finally get it measuring some fermenting wort.
