To master the Gamma RC37Z, you must change your perspective. Do not fear the heat—measure it. Install a $40 thermal probe and a $20 fan. Adjust your PWM frequency. Recognize that 70°C is not "hot"; it is "nominal."
The Gamma RC37Z is a workhorse that runs warm by design. As long as you respect its thermal limits and provide adequate airflow, that "hot" feeling is simply the sound of torque being delivered. gamma rc37z hot
