I have been wondering for a while, if MGM can make a ESC that doesnt require a fan and always runs cold why cant other companies do the same, they are pricey but there is a reason they are they use higher quality components..but at 4 bills you better be sure...I have been running a Castle HV 110 with the latest software and firmware with a pistix adapter for a little while now and it is very smooth setup for less than $250 the only negative is it has no brakes
