I have a fan on my Meade Dob. I've found it draws very little power and will run on 6V or even 3V for hours on end. I purchased a Tevion portable battery pack (3.3V to 16V) from Aldi and run the fan at 3.3V.
You probably only need to run the fan for a few hours until the mirror cools down but I tend to forget about it and it runs all the time.
