Checking the status of your new i9 14000k build to ensure it's functioning properly.
I assembled a new PC as described. The system uses an i9 14900k with Asus TUF Gaming Z790 Plus WiFi, 48GB DDR5 RAM, and a 2TB M.2 SSD. The RTX 5080 Founders Edition is on its way and not a concern. I also have a Kraken AIO watercooler with 1000W capacity and MSI Gold modular PSU. My main issues are core voltage and temperature. Idle temps sit between 36 and 46°C, core voltage remains low under load (1.37–1.45V), and it spikes briefly to 1.474V in the armoury crate (though uncertain). CPU temps average around 70°C, with a peak of 85°C. I’ve updated the BIOS and microcode, avoided undervolting due to boot issues, and reverted to factory settings with XMB enabled. I’m considering a local shop for further adjustments if needed. Stability tests pass on XTU, but benchmarks show core temps often exceed 95°C and stress tests above 90°C. I’m unsure if these readings are typical for a high-end i9 or something to worry about. Coming back to PC gaming after four years on a gaming laptop, these numbers feel quite different from what I’m used to. Would this be normal for my setup, or should I be concerned? Appreciate your advice.
Loading games demands a noticeable strain on the CPU. Mid-70s performance is typical during downloads on a 14900k processor.
Updated the BIOS occasionally because compatibility problems can occur. Verify your BIOS version in system info and review the release date on your motherboard manufacturer's website (specify the exact model) under utilities -> bios. Note: Just finished reading—have you already updated your BIOS? Also, confirm it's the "Plus wifi" variant, not D4.
It was the first step I took. The latest battery specs are 1805. I’m okay leaving it at a store to confirm everything’s safe. I’ve already invested a lot, so another couple of hours there won’t be a big issue. Just a concern about the voltage being too high, though I don’t have any real data except from old units I’ve had before.
I rolled back the BIOS, reflashed, reinstalled Windows and returned to undervolting. This time everything is functioning perfectly. I went down to -0.045v, and after stress tests and benchmarks it looks stable. Interestingly, when load increased, idle temperature rose slightly—around 45 degrees—but not excessively. My downloads show temperatures in the 65-70 range. The CPU also ran higher than before in XTU, and I completed a one-hour stress test with performance matching expectations. I might lower the undervolt further, but I’m satisfied it’s working well and I don’t want to risk anything.
