Despite heavy cooling efforts, the CPU still limits performance.
Hello! I don't understand what's going on or what steps to take. The attached graph shows what a Cinebench run looks like. The final drop indicates the program ended, but I'm sure it continued without issues. I've tried changing the thermal paste, yet results remain unchanged. The CPU stays locked in place right from the start of the test. Could this be related to the AIO or the CPU? I'm really confused. Here are the system details: Processor i9-14900k, Case Corsair 5000X, CPU cooler Corsair iCue Titan 360, Fans set to extreme on all sides, exhaust fans at maximum speed, motherboard Asus Z7950 Dark Hero.
This component tends to overheat significantly and can be tough to manage with cooling solutions. Have you installed the newest BIOS? If not, consider updating it, as previous versions had known problems that may lead to premature failure. It also enforces power restrictions that can raise CPU temperatures but might reduce overall performance.
Sharing this just for history. I upgraded my BIOS and adjusted power settings to cap at 253W, using the Intel profile available under "extreme." This fixed the overheating problems—maintaining around 80°C during bench tests—but I now limit voltage and only reach about 4.7GHz of the 5.7GHz boost. There’s a clear trade-off. Also, my RAM setup is now inconsistent with the new BIOS. I managed stable performance at 4800MT/s, which is significantly lower than the 6200MT/s I previously achieved—though it made running 192GB in a 4×48GB configuration much more manageable.
