Abstract The present work provides an experimental and numerical procedure to obtain the geometrical position of the
hotspots of a microprocessor using the thermal images obtained from the transient thermal response of this
processor subject to pulsating stress tests. This is performed by the solution of the steady inverse heat transfer
problem using these thermal images, resulting in qualitative heat source distributions; these are analyzed using the
mean heat source gradients to identify the elements that can be considered hotspots. This procedure identified that
the processor INTEL Core 2 Quad Q8400S contains one hotspot located in the center of its left… More >
