Thermal Electronics Tutorial (2/2) - Heat sink coating - does it matter?

#74 In this video I look at the impact of paint on the performance of a heat sink - usually heat-sinks come in 2 flavors: bare aluminum or covered in black paint. I try out both types of heat sinks to see just what makes them different, and look at why the painted one is different - other than the paint.
