how much power do you get out of your meade 6-SN?

After reading someother post I am wondering if the changing night temp is getting me. Has anybody installed a cooling fan on the scope?
When I recieved it the plastic cover over the back of the mirror cell was loose. I am currently thinking about taking that apart and fixing it and adding a fan mounted to this plate. Any ideas about the best way for the air flow to be? In or out. I haven't done this yet because I was afraid to induce foreign matter into the scope.
I had hoped that being in an observatory and outside all tha time that cool down wouldn't be an issue. Starting to think

I don't have YOUR scope...but I have your problem. I have the 10" Meade, and after trying for 10 days in a row on Jupiter, I can not take it beyond 192x as of yet (117x being optimal, 192x pushing it as far as it can go without looking like Venus with moons). Last night was interesting, because it was the first time I viewed the Moon thru the new scope and pushed it up to 357x before the 'swimming' became intolerable. The best views were once again at the 192x, but with the Moon being such a bright and visibile object, it also highlighted all the atmospheric instability, showing me clearly WHY Jupiter will just not come in very well at high magnifications. (sure glad I got rid of that electric focuser, because chasing focus is a pain in the butt by push button)
Well, I'm using a 9mm el cheapo lens from my suburban backyard with my 10" and it's just fine. Don't have anything higher as of yet. Using the barlow with the 9mm is a bit much. With the barlow it's nice and big but THEN I get the heat waves, etc.
