Do you have SELinux enabled and in enforcing mode? When I try it I see
the following message in syslog:

localhost kernel: [4318977.190860] type=1400 audit(1393589239.761:26): avc:  denied  { read } for  pid=23165 comm="chronyd" name="hwmon0" dev="sysfs" ino=15502 scontext=system_u:system_r:chronyd_t:s0 tcontext=system_u:object_r:sysfs_t:s0 tclass=lnk_file

chronyd is unable to read the file and there is nothing to write to
the tempcomp log.
