- Conflicts with the Windows Task Scheduler that prevent the software from starting automatically.
- Failures in reading sensors and applying ventilation curves after restarting the system.
- Inconsistencies in the control of specific hardware fans and initial calibration errors.
If you've started tinkering with Fan Control to manage your PC's temperatures, you've probably come across some erratic behavior after restarting The computer. It's a powerful tool, but sometimes Windows gets capricious and makes the settings you've spent so much time adjusting disappear or simply not apply.
From fans that get stuck at a fixed percentage to programs that refuse to open on their own, the problems are varied. The worst is when you feel like the software has corrupted task system Windows can leave you stuck in a loop of errors with no easy way out. Let's delve into all the reasons why. Fan Control loses settings after Windows restart.
Problems with automatic startup and Task Scheduler
One of the most common headaches is when the automatic startup option in the program settings doesn't respond. Sometimes, this causes a critical failure in the Windows Task Schedulerwhere a constant warning appears saying that the "fancontrol" task no longer exists, even if you try to update the list endlessly.
To solve this problem, simply disabling the option in the app isn't enough. A manual cleanup is necessary, removing the phantom entry in the path System32\\Tasks and, most importantly, delete the corresponding key in the Windows registry, specifically in HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\WindowsNT\\CurrentVersion\\Schedule\\TaskCache\\TreeOnce the trace is cleared, the Fan Control startup option may magically work again after a restart.
Sensor failures and ventilation curves
Some users are experiencing a problem where, even though the program starts, the sensors don't activate automatically. This forces them to press [a button/button]. CTRL + R to reset the sensors manually; otherwise, the fan speed remains static. This is critical because, even if you have a curve configured so that the fan speed increases to 100% when the CPU Once the system reaches 90°C, it can Ignore these instructions and stay, for example, at 35%.
Additionally, there are cases where the fans do not start immediately upon loading Windows, remaining off for several minutes. This may force the user to reduce processor frequency in the power plan to prevent overheating while the fan "decides" to start up, which is unacceptable in professional work environments such as audio production.
Calibration and hardware limitations
When using assisted configuration, the program calibrates each component, but sometimes the fans get stuck in a percentage of fixed operation after restarting. In these cases, clicking the "Calibrated" button may force the fan to return to its idle value, although the process may be confusing for the user.
It's also important to consider the physical limitations of the components. For example, on some graphics cards, such as the RTX series, you might see only two controllers for three fansThis is not necessarily a Fan Control error; rather, the hardware groups the fans under the same control channel, causing them all to spin but allowing you to manage only that group.
The stability of Fan Control depends largely on Windows not blocking its startup tasks and on the sensors being recognized correctly. The key lies in clean corrupt records Check the system and verify if the hardware allows individual or grouped control to avoid frustration with temperature curves. Now you know why Fan Control loses its settings after restarting Windows.
