Temperature is a key parameter due to its impact on timing, energy, and reliability. A setup to measure temperature in runtime with high spatial and temporal resolution would help to study the thermal behavior of processors. Currently, Infrared Thermography infrastructures has been developed to measure the temperature in real-time. Since the infrared opaque metal heat sinks need to be replaced with an infrared transparent heat sink in these setups, oil based cooling solutions have been proposed. However, oil is not a representative of a metal heat sink because measurement with oil based cooling can change the thermal behavior of the processor. In this paper, we discuss a representative oil based cooling solution, and show that it has the same thermal response as a metal heat sink.
