Apparatus and methods for predictively controlling the temperature of a coolant delivered to a treatment apparatus configured to non-invasively treat a patients tissue with doses of electromagnetic energy. The treatment apparatus includes a closed-loop cooling system connected with an energy delivery device used to deliver the electromagnetic energy to the patients tissue. Coolant is pumped from a reservoir to the energy delivery device in the closed-loop cooling system. The control temperature of the coolant in the reservoir is adjusted based upon the specific room air temperature. This predictive adjustment promotes better control over the coolant temperature at the energy delivery device by lessening the effects of heat gain in transit from the reservoir to the energy delivery device.
