Check for voltage spikes on the Z490 board.
This happens when the motherboard maker automatically speeds up the CPU you put in. Turning off features like multicore enhancement or similar in BIOS restores the original Intel specifications, eliminating unnecessary heat and power consumption.
Intel CPUs tend to draw excessive voltage at default settings to ensure long-term reliability. This approach allows Intel to maintain stability without frequent adjustments. Consumers might notice instability if their system lacks sufficient power, prompting Intel to add a small surplus. By testing your setup, you can lower voltage without compromising performance. Keeping it stable helps cut power use and heat output. For instance, a 10850K on a Z490 board shows this principle. If your setup meets expectations, no changes are necessary. For Asus boards aiming to reduce voltage, configure a negative offset in the BIOS—this will lower power consumption and manage temperatures effectively.
It seems there was a recent adjustment. My wife's 8700 non-k model runs smoothly at about 1.15 to 1.2v max even when idle. I just lifted the power limits and it works fine. The same goes for my son's 9400—it doesn’t really draw much power either. Both have lower SKUs and aren’t K chips.
