I possess an i7-9700k that has been auto-overclocked, with temperatures climbing up to 95°C.
Good afternoon, I have a few queries about overclocking my i7-9700k. My computer has been running with auto settings in ASUS BIOS for over a year now. It’s been stable so far, but recently during a Call of Duty Warzone session, the CPU temperatures climbed to 90-95°C. I understand these are quite high, and I’m hoping manual overclocking could help bring things down without the auto system cranking the voltage too much. Could you guide me through the process? I’ve read that it might yield better results.
Here are the details of my setup:
CPU: Intel i7-9700k
Motherboard: ASUS ROG STRIX Z390-E GAMING
RAM: G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300)
Graphics Cards: MSI NVIDIA GeForce RTX 2060
Power Supply: CORSAIR RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular
Tower: Corsair CC-9011035-WW Obsidian Series 750D Performance Full Tower Case
CPU Fan: Noctua NH-D15, Premium CPU cooler with 2x NF-A15 PWM 140mm fans
Storage: ADATA XPG SX8200 Pro 1TB 3D NAND NVMe Gen3x4 PCIe M.2 2280 SSD (R/W 3500/3000MB/s)
Please advise on the next steps, as I’m not very experienced with this process. Thank you ahead of time!
Here is the useful information about frequency and voltage again. When using air cooling, aim for the lowest possible vcore. The Coffee Lake Refresh specifications include various frequencies and voltages across different temperatures, with performance details provided for each.
Have you checked cpu-z for the current OC settings? If you've been using it for more than a year, have you cleared the dust from your CPU cooler? Check if this helps lower temperatures.
You might find vcore on page 6 of the manual if you decide to adjust it.

There is minimal dust on the blades or heat sink, which means I’m not that affected. The clock speed varied between 3.5 and 4.9 ghz based on the BIOS’s automatic adjustments. I just saw a YouTube tutorial about overclocking my motherboard and CPU. It appears to be improving now by lowering the voltage and keeping the CPU at a steady 4.9 ghz. The video I viewed is

I thought my issue might have come from the BIOS profiles setting voltages too high, so a manual overclock could be more effective. While playing Warzone, I noticed CPUID HWMONITOR was active and my voltage readings reached over 1.4 V for VCORE, which likely caused stuttering when throttling occurred. I strongly suggest checking the YouTube guide—it covers everything about overclocking the Z390 board.
Which adjustment were you making? I shared the same question yesterday yet no one replied. My voltage remains high at 1.4 with the auto OC profile (OC Tuner II) and XMP Profile II. I switched SVID Behavior to Typical Scenario, causing the voltage to drop to 1.296 and the maximum temperature to stay at 66°C during games. However, after that, any game not locked at 60fps causes crashes, freezes, or restarts my PC. ??
I don't have the XMP Profile, just a manual setting with a voltage of 1.3 V at 4.9 GHz. Watch his video for details on what to do if your computer still crashes after manually increasing the CPU frequency. He advises making small adjustments one at a time when overclocking, remembering the last stable configuration. If it keeps crashing, lower the frequency slightly and increase the voltage in small steps—like from 1.3 V up to 1.31 V, then 1.35 V, etc.—until stability is achieved.
