Not at all.

These switches all have a high and low switch. They're shared ground 3-pin switches.

I got a 940 shroud, fan, and controller. If I didn't have one, some heavy-duty relays wired up so the high-speed switch disconnects the low-speed circuit would work too.

You would need a 5-pin relay with NC and NO outputs 87 and 87a. Run power to actuate the low-speed fan relay on the NC pin 87a, then 87 goes to the high-speed circuit until the high-temp switch opens. I should draw a diagram.
