The problem I do not think is in the bios, I run the HWinfo32 software on windows 7 and the fan value is read continuously and correctly (in attachment)
In Debian, I would also like to point out that three fans are detected: Fan Processor: fan2: fan3: While my Dell Studio 1537 notebook has a single fan belonging to the component that manages the heat dissipation of the processor and the video card. Heatsink component: DP/N 0M139C I also noticed that sometimes sensors show too much value for the value fan3: 40981 RPM dell_smm-virtual-0 Adapter: Virtual device Processor Fan: 2837 RPM fan2: 2833 RPM fan3: 40981 RPM CPU: +41.0°C CPU: +52.0°C Other: +49.0°C GPU: +57.0°C I would also like to know what temperature should I consider ?: dell_smm-virtual-0 acpitz-virtual-0 coretemp-isa-0000 I hope this bug of the "dell_smm_hwmon" module can be solved, I would not give up reading the correct temperature and fan values.
