Hi,
I have the same problem on my TP R60.
Adding (127, 66, 32767) at the end to /etc/thinkfan.conf lead me to have the fan running at disengaed by auto. This results in seltem having temparute over 85°C.
Further I found, that the VID is to high by default. If I set the governer to userspace 1.833GHz and reduce the VID using
wrmsr -p0 [1] 0x0199 0x0b20
The temparature goes not over 65°C.
The governer "ondemand" switches the MSR 0x199 between 0x0613, 0x081c, and 0x0b28. This 0x0b28 should be reduced to 0x0b20 and every thing would fine.
