Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Maybe I should reinstall my OS w/my DVD because maybe Fan Control will then work, allowing me to configure it properly prior to uninstalling. I reinstalled my OS to my internal HD w/the DVD I bought from Apple but the result was buggy so I used my cousin's DVD, which seems slightly older because its iTunes is slightly older. And Automator wont auto-play an iTunes radio station when my computer auto-awakens in morning, as it did w/the external HD. But I cant import Firefox bookmarks from the external HD or my backup external ,LaCie HD.
But, very recently, I reinstalled my OS on my internal HD. A techie (w/some connection to Apple) said my internal HD was permanently dead. I installed Fan Control after internal HD failed 6 months ago and I started using an external, Maxstor HD. This may confuse looking for Fan Control parts to uninstall. I have 3 libraries, system, user, and another. I must, I believe, have proper rpm before uninstalling. Also: all four current temps are 28F or 32F. But, CPU fan is 4650, HD fan is -107 (minus?!) and DVD fan is -107 (minus?! and when not used!). I'm unsure if I need even a properly working Fan Control. How can I uninstall Fan Control (not SMC Fan Control)? It wont respond to its controls.
