the stock fan is only rated to 9v or some shit. If you run 3s on the stock fan it'll eventually burn out (never had one do it though) with the upgraded fan its rated at 12v so it can handle 3s.

i use the 35a version of that speedy on 3s and dont run a fan. No issues thus far. The esc doesnt really get much above 40*c even when its 35* ambient and humid as all hell. As long as you run with the thermal protection on its not an issue.

I run the 35a as well with no fan on it in the blitz and it gets a thrashing but is still working really good. Very Happy cheers
