Hello,
Â* I have a Toshiba Tecra M4.Â* It works well under Fedora 16 except that the fan is constantly on at high speed now.Â* I don’t know if it’s because of something I’ve loaded, a setting I’ve modified, etc.
Â*
Â* If I add the option “acpi=offâ€� to the boot command then the fan stays at a reasonable rate.
Â*
Â* Unfortunately this also slows down the CPU.Â* My guess is that the CPU speed information is contained within the ACPI interface.
Â*
Â* Does anyone have experience with controlling the fan on a Toshiba Tecra M4?Â* Â*I didn’t always have this problem so it’s either something I changed or something that was changed by an update somewhere along the way.Â* Since I run the machine in various temperature environments and with different loads I thought the problem was just the CPU running hot but booting into aÂ* SLAX off USB showed the machine running normal – fan running slow, occasional speed up, then back to slow.
Â*
Â* Any help, pointers, etc appreciated.
Â*
