On this video I will be delidding the latest flagship CPU from Intel, the 13900KS, which runs at nearly 100 degrees already at stock in simple workloads like Cinebench. This process allows us to stabilize the stock operation, and gives us at least some kind of chance to do any overclocking. As these temperatures are so high already at default, the first thing you generally do is undervolt the CPU and check if it remains stable.

If you ask me, the realistic gain from delidding alone is between 8-15 degrees celsius. If you use the Thermal Grizlyy or Thermaltake contact frame as well, you can generally gain a few more degrees from the overall temperatures on top.

You must use a lot of force when you delid these soldered CPUs, and once you feel the Indium solder + the glue starts to give up, just keep on tightening the screw to make sure the IHS gets completely loose. Then, you must remove the black silicone glue residues from the CPU's PCB, as well as from the IHS to make sure you get adequate contact on the Die. I use cleaning alcohol and plastic object to scratch the silicone glue resides from the surfaces.

Delidding the CPU allowed me to overclock the CPU from the stock level of 5.5GHz for all of the P-Cores, to roughly 5.7-5.8 depending on the voltage used and given workload. The hardest part about daily overclocking is the voltage used for AVX based situations, as the temperatures will be very high. You can easily guarantee stability with the AVX negative offsets.
