Does running i8kmon, thermald, and sensors simultaneously have known resource contention issues that cause fans to start spinning at lower temperatures than the thresholds I've configured? Is getting Dell laptop fan speeds and noise under control a solved issue?
I'm running Ubuntu 20.04 on a Dell Precision M6600. I'm using i8kmon and still get fans spinning at higher RPMs triggered at lower temperatures than the thresholds I've configured. I've read these posts and others. All solutions are temporary, at best.
- i8kutils i8kmon uses wrong thresholds after resuming from suspend
- Dell fans not working
- How do I get fan control working?
I've disabled BIOS fan control with smm,[dellfan][0], [dell-bios-fan-control][1]
Hardware Sensor Indicator, i8kctl and sensors output all show temperatures below what should trigger any fan activity.
i8kctl output:
