If you are running fix timing that is probably generating a load of unnecessary heat because you're running the timing all the time. If you run variable dependant timing, the timing value you set is relative to throttle input. For example if you set up 20 degrees variable and have only 25% throttle input you're running about 5 degrees timing. If you are at 50% throttle you are running 10degress timing and so on until you are at 100% throttle when you finally hit 100% of your pre-set timing.
What this does is run the motor efficiently(and cool) at slow speed then dumps a load of timing in when you need it. Not to mention it gives a very progress and nice feel to the throttle.
Other than that you may just be running too much timing for your motor as they are not all the same. Personal even though i'm running a x12 i don't like them because they are so fussy when it comes to getting the gearing right.
One final thing is the tekin guys can only be measuring the external temperature of their motor. If you're taking your reading from esc telemetry you're taking it of the rotor which is going to be 20-30c hotter than the can.
