I'm going to try one of these for the fan on my Mark IIhttp://www.amazon.com/Lux-WIN100-Smart-

What do you think ?
Looks good for the price & the ratings are good too! Only problem I foresee is that unless you run a long extension cord, it will take it's temp readings too close to the stove itself.
I have my blower on an appliance timer which is all I really need since I turn my stove way down during the day & overnight & wouldn't want the blower running to drop the stove temp down too low anyway. (I generally only crank my stove late afternoon through the evening)
