    HWiNFO can't see fans on newer Dell machines?

    They made the change with AMD systems at the same time. If your system is 2021 or later then it will likely not work.

    HWiNFO can't see fans on newer Dell machines?

    Both programs should "probably" work with Dell laptops released in 2020 or earlier (Intel 10th-gen CPUs or older). They changed the fan interface with 2021 / 11th-gen systems.

    HWiNFO can't see fans on newer Dell machines?

    To my knowledge there are only two ways to do this right now. Dell Fan Management, a tool written by me for managing Dell laptop fans. I have largely abandoned work on it because Dell changed how fan control works starting with their 2021 systems, so manual control is either impossible or no...

    HWiNFO can't see fans on newer Dell machines?

    Hi @Martin, I just noticed this thread. I am author of Dell Fan Management and I would be happy to pass along any information to help with this implementation. I did a lot of slinking around Dell's libsmbios C code (for Linux SMBIOS support), a lot of BIOS token/variable dumps, and some...

    New Dell systems EC sensor values not available (& fix)

    Typically, HWiNFO64 can show a block of sensor data from the "embedded controller" in Dell laptops, including temperature and fan speed values. In at least some of Dell's new Tiger Lake Precision mobile workstation line, the EC data cannot be read (HWiNFO64 does not show the EC data). I have a...
