I'm running Ubuntu 16.04 Xenial and need to control my fan speed for my 32-bit Acer Aspire 5315 with 1 GB RAM. There are old directions for 64-bit here, and some for 32-bit here, but these all assume old paradigms (
/proc/acpi/thermalzone instead of the newer
/sys/class/thermal—simply replacing the paths doesn't work). The fan never turns on so the system overheats. Acer had a Windows utility that controlled it but this doesn't work on Linux for obvious reasons. The solution appears to be to download a BIOS update issued by Acer, but they've only released a Windows executable and I have Linux on this. I'm trying to find a workaround.
pwmconfig doesn't see any sensors no matter what I try (I've already tried this).
