Thermal design power (TDP) is vital when shopping for the best CPU cooler. The Intel Core i9-13900KS is a power-hungry chip that can draw more than 300W of power from the PSU, but after seeing how well the Noctua NH-P1 performed with the AMD Ryzen 7900, I thought “There’s no way it could handle the 14900KS, right?” There’s only one way to answer whether you can passively cool the 14900KS and that’s to put it to the test. In the name of science, I installed the Noctua NH-P1 with no fan and the Intel Core i9-14900KS on our open-air test bench to see what would happen.
