Removing your Heatspreader
Published: 6th May 2006 | Source: Overclock3D |The History of the IHS
Remember back in the day all CPU's had their core exposed? This caused many problems, from novice users cracking their cores, to hardcore overclockers killing their CPU's with unorthodox cooling solutions. The Intel Pentium 3 was the first mainstream CPU to feature the IHS. Following that, was the Pentium 4, which included an IHS. Intel's IHS' were mounted the same way AMD K8 CPU's IHS are, with some epoxy and thermal paste. This caused many problems, because sometimes the IHS would not make proper contact with the core, and temperatures would be abnormally high, hence hindering overclockability. So to tackle the problem Intel started soldering their IHS' to their cores.

Since the introduction of the K8 series CPU, AMD has been using epoxy to mount their IHS. To ensure proper thermal transfer between the core and the IHS, they applied a layer of thermal paste. Sometimes too much or not enough thermal paste get's applied at the factory, or the IHS isn't seated properly on the core. This can make your CPU run abnormally warm, hence hindering your overclock. To solve this, people remove their IHS. When you remove the IHS, your heatsink makes contact directly with your core vs the heat spreader, instantly having better contact with the CPU.
