Methods and apparatus control the temperature of an electronic component of a computer. A temperature sensor is read that measures a temperature of an electronic component of a computer. The speed of a compressor is adjusted based on the read temperature to maintain a pre-defined temperature range for the electronic component. The compressor compresses a refrigerant. The refrigerant is sent to a condenser that condenses the refrigerant. The refrigerant is sent to a heat exchanger that is thermally coupled to the electronic component and that transfers thermal energy from the electronic component to the refrigerant. Finally, the refrigerant is sent back to the compressor. Solenoid valves can be used to control the flow of refrigerant to heat exchangers for one or more additional electronic components.
