take a look @ /etc/sensors.conf (or Suse's name for it) read the _header_ of the file and look for your hw sensor and change the "compute" directives... (maybe you've to delete one, or remove a * 2 or / .5 ...)
you can adopt your changes when run (as root) sensors -s /etc/sensors.conf
... (now check the values again!)
(since you did neither say which hw sensor you have nor what the exact output
look like, you've to do all by yourself!
example / fresh sensors.conf
