yes, this is true - even booting under knoppix and loading some special
drivers, u can pass -1 (or some special value) to the linux driver and it will
let the fan spin lose...and it definitely goes far faster than the
approximately 3.5K rpm it does with fan_level=7 and fan=0.
I have a Thinkpad Z60m, single core, 2 GHz. Everything original except the
memory, increased to 1.5 GB.
in my case, i think the GPU heats up pretty badly... it is very hot where I
think the video card is located.
I've posted to both mobile@ and acpi@ under the subject of 'Management of
Thermal' with my woes while on the latest 6.2 before 7 went into Beta1. Since
my upgrade to 7 i've had no major issues with heat. The emails i've posted
previously show the settings i have been using, as well as whatever I had done
in knoppix to manage the speed of the fan.
cheers,
B
