I have set a fan speed curve, but it cannot control it well, especially in low-power scenarios (office applications and videos that do not rely on graphics card performance). And, the fan keeps starting and pausing (or in other words, the speed keeps changing but doesn't match the curve). In theory, when GPU is at a low temperature(<40℃), the fan speed is 0. This situation will distract me and worry about the lifespan of the fan. Which driver version can fix this problem? I think fan control should be simpler than fixing game compatibility, right？

Hi FLOW_999,
Thank you for posting in our Community and for bringing your concern regarding the fan control behavior on your B570 to our attention. Your observation is valid in theory, a fan curve set to 0% below 40°C should prevent the fan from spinning. However, what you're experiencing, frequent spin-up and spin-down behavior, may be the result of how the embedded controller (EC) or firmware interprets thermal thresholds in conjunction with the GPU driver. While fan control might seem simpler than game optimization, in practice, it's often tightly coupled with the system firmware and OEM-specific implementations, not solely the GPU driver. The Intel driver does not directly control the fan curve, instead, it communicates telemetry, and the system firmware or OEM software usually executes fan control based on those signals.
Download and install the latest available driver from Download Center.
Refer to Clean Installation of Intel® Graphics Drivers in Windows for installation instructions
Have a nice day!
