how to set max temp for module coretemp?

[vince at planetvince.info (Vince Herried)]

In my /etc/sensors3.conf file I have
chip "coretemp-*"

 label temp1 "cpu0"
 label temp2 "cpu1"
 set temp1_max      40
 set temp1_max_hyst 37
 set temp2_max      52
 set temp2_max_hyst 47

[root at lap2 bin]# sensors -s
Error: Line 2455: Failed to set value
Error: Line 2456: Unknown feature name
Error: Line 2457: Unknown feature name

I would like to be able to set the max temps
but apparently the coretemp driver doesn't allow it?

???
