I just installed the program and changed my fan speed to my likings, I love the program but the only problem is that I need to reset the fan back to how it was before I installed the program because my computer is having issues
That depends on machine you have. It should be sufficient to remove custom auto control mode (in case you use it) and click the "System Auto" button.
If that doesn't do the job, you'll need to completely power off the machine - remove battery and AC adapter. Wait a few minutes and then turn on.
