The ix8 has built in "power" profiles that are supposed to optimize the timing and manage current. I'm not sure how it would handle a motor that isn't set to zero on the sensor board. By changing the timing on the motor and having the ix8 trying to control the timing it may be really messing the system up.

The reason this may be an issue for the ix8 vs other sensored 1/8 controllers out there is that the ix8 is 100 percent sensored. Most if the other escs are sensored for start up only and then switch over to sensorless mode once its turning so the motor end bell timing doesn't really matter as much.

I don't know if what I'm saying here is really your issue. I'm just making an educated guess. I would make sure the timing on the motor is set to true zero like most other 1:8 4 pole motors.

If a esc overheats it's fine usually. It just shuts down with the internal thermal protection and is fine again once it cools off. If the motor overheats then it's usually trashed. Once the motor gets to hot the magnets start to weaken which in turn makes the motor run with less power and create even more heat. If the motor was over 200F it's probably toast and trying to make it work will just create more issues.

As far as what temp the fan turns on at.... I don't know, I've never even installed the fan on mine. Ive never gotten it over 130 without the fan so I never bothered.
