Here is the heatsink I'm using right now. http://www.dealsonic.com/thera1ddrsdr.html . It works but does not fit that well. I've got the two heat sinks side by side runing long ways on the quark controller. They are not quite long enough and a little wide. I might order one more set and run them the other direction and cut the extra off. That way it would be a cleaner fit.
Fans do have some good points.
I have a lipo setup in my mini lst and on a few occasions I forgot to unplug the battery. Once it drained the lipo battery to the point were I had to charge it as a NIMH battery till it got a charge in it because my charger wouldn't even charge it. I was waiting for it to go boom but it didn't, it also was never the same either and I have since pitched it. There is no misstaking wether or not my Emaxx is on, the little novak fans sound like a turbo spooling up which is kind of cool in itself. Just imagine ruining $280 worth of batteries just because you forgot to unplug your batteries.
As far as run time goes I havent noticed a difference, there is a difference it is using a fraction of an amp but its not noticable.
As far as wiring complexity one more pair of wires isnt that big of a deal.
Just my 2 cents, I never knew fans were taboo with so many people.
In the end to each his own i guess.
Never fight an ugly man..... he has nothing to loose
