The extended Temp Compensation will not help with a hi temperature problem.
What it will do is reduce the frequency drift over a wide frequency 
range - so for maintaining frequency stability while the KX3 is heating 
up, yes that stability will be increased.  The temperature problem with 
extended transmit 'key down' times is what is causing the heating.

Cooling the PA transistors or reducing the power is is the only way to 
reduce the effects of high temperature.
The new heatsink will help, lowering the power will help, a fan blowing 
on the heatsink will help, an aftermarket heatsink will help.  Anything 
to keep the PA transistors cooler.
