RockItCool provides pure copper IHS for the daring hobby - Delid CPU

Buzz

Delid CPU is the term for prying/removing/detaching the CPU lid (IHS - Integrated Heatspreader) to replace the thermal paste between the lid and the processor die, aiming to improve temperatures during operation. This term originated from the Intel Core 3000 Series as previous CPU generations had the die soldered to the IHS. However, starting from Sandy Bridge, Intel switched to using low-quality thermal interface material (TIM), leading to inefficient heat dissipation, affecting performance and overclocking capability.

Delid CPU is not recommended for amateurs, as firstly, you will void the product warranty. This is also a risky operation for the CPU because with just a slight mistake, the processor will only function as a paperweight. After successfully delidding, you can use higher-quality TIM (such as liquid metal) and then relid. Successful cases have shown significant improvements in operating temperatures, especially under full load. Some famous modders like der8auer even thin the core for optimal heat dissipation.

Compared to the past, there are now many tools and guides for delidding CPUs, although this is not recommended and must be done very carefully, even for experienced individuals. Previously, the common post-delid options were to replace the TIM, lap the IHS, or remove the IHS and directly mount the heatsink onto the core, but these methods often led to core damage and CPU failure. Nowadays, if you successfully delid and want better thermal thresholds, you can replace the IHS with a new one provided by RockItCool.

RockItCool simply sells IHS models made from pure copper, utilizing the optimal heat conductivity of this element to enhance heat transfer and dissipation. According to the company, replacing the IHS with a pure copper one along with liquid metal TIM (which requires extreme caution due to its electrical conductivity that can potentially damage the CPU) can reduce temperatures by up to 15 degrees Celsius when tested on the latest Intel Alder Lake sample - the Core i9-12900K - from a full load of 85 degrees down to 70 degrees. Copper IHS models are also available for customers with Intel processors from Skylake generation onwards.Source
