Which actually brought me to another question about that 10K resistor. All I have here is a huge 3W10K resistor, will that still work in that fan circuit?

Hey Dom, the DS18B20 should be able to share a ground with the fan circuit but, yes, Chris' fan scheme might present some issues. Then again, that damn schematic he posted is so damn small I can hardly tell what's what - I'm going blind staring at that thing. Can you post a bigger version of it?
