Core i9-14900KS pulls up to 432W of power in Y-Cruncher

The Intel Core i9-14900KS isn’t out yet, but it’s already been delidded

Intel has always had a problem with leaks featuring their new desktop CPUs. The new Core i9-14900KS “Special Edition” is not an exception. The processor has already been seen at retailers, in overclockers hands, and apparently it has now been delidded, all while the CPU has not even been announced yet.

The i9-14900KS features 24 cores (8 P-Cores and 16 E-Cores) while offering up 6.2 GHz clock and 150W default TDP. This processor is designed for  enthusiasts and overclockers who will be putting the processor to some very extensive testing. That’s exactly this happened in this case.

This leak comes from the same person that shared the very first photographs of the new processor. A member of Overclock forums “pakhtunov” has now taken the CPU for thermal testing with stock IHS (Integrated HeatSpreader) and with the CPU delidded and reapplied with new liquid metal solution.

14900KS Delidding Temperature difference (5.9 GHz P-cores)

• Cinebench stock IHS : 85°C, 376W
• Cinebench delid : 75°C, 366W
• Y-cruncher stock IHS : 89°C, 432W
• Y-cruncher delid : 82°C, 409W

As the results have shown, the temperature has dropped from 7 to 10 °C depending on a test. At the same time, users report a 10 to 23 drop in wattage, which is a direct result of lower temperatures. According to the author, the system uses DeepCool LS720 SE Liquid Cooler with 360mm radiator.

The Core i9-14900KS is now scheduled to launch on March 14th, and we expect reviewers and overclockers to share their results at that time. Intel is yet to confirm pricing for its new processor, but as we have already observed with past “Special Edition” launches, it will no doubt cost more than $700.
