Default Hobbywing Quicrun 10BL120 fan stopped working

Hey Guys,

I got a hobbywing 10bl120 to replace my last two ESCs (they caught on fire LOL). I was running the new ESC on 2S yesterday with a 3660 3600kv brushless motor on a 1/10 scale SCT. On 2S is seemed fine, except for it randomly slowing down and stopping occasionally . That's beside the point though. I was running it on 3S today, and when I first turned the car on, the fan spun up and the car ripped! I then went over to my garage to try to add a tad of increased timing (going from 0 to 3.75) and I also changed the running mode from forward/reverse/brake to forward/brake. Then I turned it on. The fan spun up, I went out with it and it ran fine. I brought it back in, and lo and behold, the fan isn't spinning. I was checking temps frequently, and my ESC and motor barely even got warm. My LiPo is a 5200mah 80c, and I am NOT over gearing. if anything, I'm going with too much torque. I also took the fan off and made sure there was no debris in it. Any help and tips are appreciated.
