Maybe I set the limits too low on th pbooks. It looks like there's a protection in case of too long overheating, and i don't find out where it could be set in the docs. (btw, can you check that the patch you applied is the correct one, where LIMIT_REG reads: static u8 LIMIT_REG[3] = {0x6b, 0x6a, 0x6c}; /* local, cpu, gpu */ and not static u8 LIMIT_REG[3] = {0x6a, 0x6b, 0x6c}; /* local, cpu, gpu */ If this is not the case, invert the two firsts and try again...) if it is, you can try to set the limits higher by using "limit_decrease=-10" parameter. If you have MacOSX installed and if it is possible to read temperatures values in this OS, you can also check at which temperature the fan starts. Thanks, -- Colin
