We stumbled upon a rather neat post from Lam Chi-Kui which shows Intel's upcoming Core i5-7600K delidded and the original IHS replaced with a copper IHS that has both better thermal properties as well as a larger surface area.

While delidding and replacing the IHS is not something that an average user will do, it is still quite interesting to see and there will be plenty of overclockers that will do such a thing to get the most out of their CPU.

According to what we can see from the post of Lam Chi-Kui, a well known overclocker and Chief Reporter at HKEPC, the original Intel IHS, which has an area of 812mm2 and thermal conductivity of around 90W/mK was replaced with a custom copper IHS with 1000mm2 area and 400W/mK thermal conductivity.

While we still do not have any precise details, we do know that Kaby Lake should have thicker PCB compared to Skylake, so it should both handle delidding better and be more suitable for such custom IHS or even direct cooling without the IHS.

There are only four pictures published on his Facebook profile but hopefully we will see some benhmarking results soon.
