Fix for failure due to static method changes.

As of commit 9865bc28e4b5fa84fe75a8bbf9d9dcf027b09212 in the PR #67
changed the normal method's to static method's due to which the tests
related to fan control alogorithm "test_fan_control_algorithm_1
 and test_fan_control_algorithm_2" are failed.

this commit fixes this by calling method's with argument as class object.
