有冇人用 Novak GTB w/o fan?

有冇人 tried Novak GTB ESC (brush or brushless) without fan?  Fan is the weak part here for street run    I want to know if it's ok to run w/o fan.  I also saw some older version of the GTB + 5.5R or 6.5R w/o fan.  

I am using it for 10.5 and 13.5 brushless only.  Shouldn't get too hot....    anyone tried?

試用much more風扇啦,但係要睇本身有冇超齒比?

I use GTB +4.5R + 5 cell in my F103GT w/o fan, no problem in running in these winter days  

i use gtb + 3.5r +4 cell in my 415msx w/o fan play on pyc . no problem.
