This copper IHS claims to reduce the temperature of your i9-12900K by 15 degrees Celsius.

RockItCool noticed considerable savings over the original setup by removing the stock IHS and its solder and replacing them with liquid metal and this new copper IHS. With default settings, the CPU reached roughly 85°C at 5.1GHz but barely touched 70°C with these tweaks.

The RockItCool firm has been introducing devices to enhance the temperatures of Intel CPUs for some years, and on this occasion, it introduced its new copper IHS for Alder Lake, which the company claims allows temperatures on the i9-12900K to be decreased by up to 15°C. 

Along with its 100 percent copper structure, the manufacturer stresses the following qualities of this IHS:

• CNC machined with small tolerances.
• Uses the same relid system as the factory IHS
• Contact area increased by 9.5% vs. factory.
• Smooth, flat surface for maximum contact with the CPU and cooling solution.
• Only for 12ma processors. Generation. Tested at 12900, 12600 and 12400.
• The copper IHS is 100% compatible with EK and Bitspower monoblocks.
• Marked to show the area of liquid metal application to take the guesswork out of it.

This IHS costs US$32.99, and in order to apply it, we must also purchase a Delid and Relid kit, which is marketed separately for US$59.99, however when purchased together, they cost US$79.99, saving us US$12.99. It's an incredible price, but well worth it for the hardcore enthusiast seeking to maximize the performance of their processor by keeping it as cool as possible.
