Method of visually identifying thermal history of computer components

Extreme temperatures cause computer server components to fail. Once the temperature returns to normal, or the component is removed from the system, the failure cause may become undetectable. This can lead to failures that are difficult to troubleshoot and repair in the field.

Extreme temperatures over long periods of time can cause permanent failure. However, visual inspection in the field or after a part has been removed and returned to the manufacturer for analysis cannot indicate the extreme temperature over extended periods of time that led to the failure.

The disclosed solution is a method of using a chemical compound to detect and irreversibly record high temperatures for extended periods of time on computer server components.

Implementation entails placing a sticker or the chemical itself on the component, such as a memory DIMM or heat sink, to determine whether the component has been over temperature for extended periods of time.

The actual temperature indicating device and chemical composition of the indicator is a known art and is not novel; however, the use of this type of indicator within operational computer systems has not been previously disclosed.

The chemical composition of the indication device is as follows:


The intention of the indicator is to identify component case temperatures that infer exceeding the components maximum operational temperature. For example, if a component is specified as having a maximum junction temperature of 150 degrees C, and the thermal resistance junction to case is such that the maximum case temperature is specified at 105 degrees C, then systems operators use an indicator whose minimum indication temperature, including all variable margins,...
