An apparatus controls a temperature of a device by circulating a fluid through a heat sink in thermal contact with the device. The apparatus includes an adjustable cold input, which inputs a cold portion of the fluid having a first temperature, and an adjustable hot input, which inputs a hot portion of the fluid having a second temperature higher than the first temperature. The apparatus further includes a chamber, connected to the cold input and hot input, in which the cold and hot portions of the fluid mix in a combined fluid portion that impinges on the heat sink. The combined fluid portion has a combined temperature that directly affects a temperature of the heat sink. The cold input and hot input are adjusted to dynamically control the combined temperature, enabling the heat sink temperature to compensate for changes in the device temperature, substantially maintaining a set point temperature of the device.
