Hi, short version: when set to "auto" fan never accelerates beyond 2800. CPU can get very hot. Long version: I have Z61t with Core Duo 2GHz and latest BIOS (2.18, 7FHT26WW-1.08). Fan on "level 1" speed spins at about 1600 RPM, "level 7" is 3500 RPM. When set on auto, fan starts at 0 RPM. When CPU temperature reach 50 degree Celsius, fan spins at 2800 RPM. Now, the problem: fan never accelerates above this. Yesterday I generated 100% load on one core for few minutes and temperature reached 94 Celsius degrees. When I noticed it, I immediately did echo level 7 > /proc/acpi/ibm/fan, and temperature dropped to 60-70 degrees. According to Intel pages, 95 degree is critical temperature for this CPU. "auto" controlled fan should speed up. I'm using Ubuntu Feisty kernel with IBM ThinkPad ACPI Extras v0.13. Is this non-working "auto" deficiency known and fixed in later releases?
