I recently purchased a Khadas Mind 2 with an Intel i7 processor and 32GB of RAM, and I’m using it with the Khadas Mind Graphics module. While playing games, I’ve noticed that the CPU temperature skyrockets to 102 degrees Celsius, causing thermal throttling.
I’ve reached out to Khadas support via email but haven’t received a response yet. Has anyone else experienced similar issues with this setup? Is this level of overheating normal, and are there any solutions to mitigate it?
This is a normal phenomenon.
Mind is a mini PC, and our PL2 design is 64W. During usage, the power consumption can momentarily reach this level, which is a result of the CPU Turbo boost. For example, in the screenshot you provided, the CPU power consumption reached as high as 62.77W，So, the temperature may reach a high level at certain moments, but it won’t stay high for long.
In some CPU-intensive games, you may encounter thermal bottlenecks. You can try lowering the resolution or graphics quality slightly to ensure a balance between cooling and performance.
Thank you for looking into this and explaining. Is it possible to limit wattage in settings somehow (e.g locking it at 55w max to avoid throttling and get more consistent performance)?
We don’t support directly modifying the PL2 power settings.
Have you tried changing the power mode in the Mind APP? Modifying the power mode will change the PL1 power setting, which may help alleviate this issue.
Yes I tried changing the settings. If I switch from “high performance” to “balanced” my max tempreture is 98 degrees and with power saver it is too high performance hit. I guess I’ll stick to balanced. On “High performance” it hits 102 degrees, then it thermal throttles, but it still stays between 95-100 degrees for quite some time. At that point games start stuttering.
While testing, I noticed an unusual behavior with the fan. It remains quite silent for the first 10-20 minutes, even under load and reaching temperatures of 100 degrees. The fan only kicks in after 20-30 minutes, becoming noticeably louder and bringing the temperature down to manageable levels.
Is this because the fan curves are adjusted to prioritize silence over performance? Are there any future BIOS updates planned to address this issue or at least allow users to adjust the fan curves? This would help solve the overheating problem.
The fan speed of Mind is not determined by instantaneous temperature readings, but rather by sustained temperature measurements over a period of time. This design ensures smoother transitions in fan speed rather than abrupt fluctuations.
While customization of the fan speed curve is not currently supported, you might consider using ThrottleStop ThrottleStop 9.7.2 Download | TechPowerUp to adjust Mind’s PL1 (long-term power limit) and PL2 (short-term boost limit). This could help reduce CPU power consumption to better balance performance and thermal management
Thank you for your previous guidance on using ThrottleStop. I successfully managed to set PL1 to 50W and PL2 to 60W and configured ThrottleStop to start with Windows startup. With this change CPU temperatures seem to be improved. I run 30 min stress test and observed maximum tempreture was 88 degrees Celsius with consistent clock speed. There were no signs of persistent thermal throttling and had greater stability than before.
Once again thank you for your support with my issue.
