Issue with overvoltage temperature on 14700KF CPU with ASRock Z790 Taichi Lite motherboard?
Issue with overvoltage temperature on 14700KF CPU with ASRock Z790 Taichi Lite motherboard?
I just bought this board and cpu, but the temperatures are way too high – around 26-28 degrees even when I play CS2. The ambient temps are also that high. I have an Prolab AI 360mm LCD aio, and when I set a fixed voltage between 1.365 and 1.380, or use any other setting, the temps drop significantly. I've tried using an LLC regulator with various offsets, but nothing works. Only a fixed voltage seems to bring the temps down. It's been about two months now, and I've tried almost every possible combination. It seems to stabilize the temps with consistency. Fixed voltage sometimes causes FPS drops or lag, and the game starts to lag. I'm out of options – anyone can help?
What BIOS version is installed on your motherboard? How is the AIO positioned within your chassis? What is the make and model of your case?
AIO is positioned accurately with the specified torque and the most recent BIOS.
There appears to be an issue, it's quite warm. I'll stick with XMP, -50mV undervolt and adjusted fan curves. Probably won't need to make much else. Do you have another cooler you could test for verification?
Are your computer crashes when the 14700KF becomes too warm? Contemporary processors are built to increase performance automatically, up to their safe upper limit of 100°C for this chip. At that stage the BIOS should reduce the CPU speed to avoid overheating.
HWMonitor indicates that several cores in my 7950X reach their upper safe temperature of +95°C during extended video editing sessions lasting up to 36 hours. All 16 cores remain within a range of +79°C to +87°C during those periods. The cooling solution I use is a Noctua NH-D15.
If I had added an AIO cooler like yours, I could potentially achieve another 100 to 200MHz during automatic speed increases. As cooling efficiency improves, so does the upper CPU frequency limit, which helps maintain a safe temperature of +100°C for your 14700 or +95°C for my 7950. Large AIO units generally outperform big air coolers in this situation.
I still have a functional Phenom II X4 965, which crashes when the CPU approaches its +60°C threshold by a few degrees during overclocking. Today we have a wider safety margin of 29°C to 40°C.
Unless adjustments are made to lower the voltage or modify Windows power settings, I consider high CPU temperatures normal. Whether beneficial or not, modern CPUs are engineered to operate hot in order to extract maximum performance.
You could potentially prolong a CPU's lifespan and minimize electromigration by limiting its peak temperature, but I’m content if it lasts another decade. I’d rather stick to Standard or Sports mode than risk sluggish throttling, especially since switching transmission modes would only slow me down.
With electricity costing about US $0.34 per unit, I have a choice: finish a transcoding faster at full power or wait longer if I cap CPU and GPU usage.
I might save money by undervolting, but I’m more confident my system won’t fail near the end of a lengthy job if I stick to stock settings. It’s frustrating having to restart everything after a crash.
I’m fine with everything being on auto—no tweaks needed, just let the system run at its best with my 360mm AIO. My CS2 or Dota2 shouldn’t push temperatures above 95, and they should only climb to around 70 or 80 with ambient temps.
It depends on the configuration.
When you mentioned "just purchased," are they brand new or used?
Did a notification appear during the first boot regarding the settings? If yes, what option did you select?
If you selected "water cooling," the motherboard automatically overclocked the system, making it very aggressive.
Restarting the BIOS should resolve this issue, and you can try a different setting.
Additionally, consider checking the load line calibration—it adjusts voltage based on CPU demands. If it's too aggressive, voltage may become excessive.
I don't know the exact temperature your game sets for the CPU. It depends on how demanding the programs are. The more processing power needed, the hotter the CPU will get before it hits the throttle limit.
I usually skip checking CPU temps unless something goes wrong. On my 7950, it's fine up to 95°C. With Intel systems, I go up to 100°C. If the CPU stays too hot, I change the fan speed settings.
In summer, I increase the fan speeds in the BIOS when the room gets warm to 30°C. In winter, I lower them when the temperature drops below 12°C.
