The IHS temperature is NOT important to overclocking, which is what Cathar is saying.
I believe that the IHS temperature is used in testing because it's an easily acquired number - you can't drill a hole in a CPU, but you can in a metal plate above it. IHS based testing will not indicate what the CPU temperature below is, but that's not the goal. The goal is to see whether Block A will produce a warmer or cooler CPU than Block B. Measuring above the IHS also removes the IHS-CPU TIM joint variable, so you don't have to worry about that degrading.
