Renowned overclocker Roman 'der8auer' Hartung has delidded Intel's latest Core i9-14900K processor and applied liquid metal thermal paste to maximize thermal conductivity. This should cool down the CPU as much as possible without using exotic methods like liquid nitrogen. The experiment has proven that the difference between 13th Generation and 14th Generation Core CPUs is negligible, and delidding as usual results in a significant temperature reduction.

The delidding process was carried out using the Delid-Die-Mate tool produced by Thermal Grizzly, a company that works closely with der8auer. He them applied Thermal Grizzly's Conductonaut Extreme liquid metal thermal paste and used the CPU contact frame to maximize package uniformity and provide the best possible contact with Corsair's 360mm all-in-one liquid cooling system.

der8auer has proven with past experiments that delidding, accompanied by the application of liquid metal and the frame, leads to a substantial decrease in CPU temperatures and even power consumption (by around 10W) without compromising performance. On average, a 10°C reduction in average peak core temperatures and an 8°C decrease in E-core temperatures were observed with the 14900K, alongside a minor reduction in power consumption. Meanwhile, the removal of the IHS and application of a better thermal interface resulted in a maximum P-core temperature reduction of 12°C.

der8auer's findings further underscore the effectiveness of the delidding process, showcasing a significant improvement in thermal performance as evidenced by the reduced temperatures. The legendary overclocker said he did not expect such significant improvements because of delidding. However, Intel's 14th Generation Core i9-14900K processor is hotter than its direct predecessor, and that makes delidding a viable technique for enhancing thermal performance of this CPU.

Of course, delidding is also pretty risky and voids the warranty. It would be much better if Intel could improve the built-in heatspreader and other aspects of the chips for everyone, but for now this is something for enthusiasts who want to maximize cooling and performance.
