High-temperature alarm

I have a brushless setup. It's the old feigeo 9L motor with the warrior 9918 (later renamed to 9920).

The motor gets hot since the motor is too small (i'm assuming).

Is there an on-board high-temperature alarm I can buy that will make audible, as well as light alerts when the motor reached a critical temperature (such as 165 *F)?

I already have an on-board temp reader, but there is no alarm.

I have one and I love it. It works flawlessly. I am going to buy two more with my next order.

Oh wow, it's pretty cheap too. Thanks!
