That sounds like multiple problems to me. It sounds like you helped someone unload a lemon (on you). If you can get your money back, do so.
Overheating and Fan error could both be a build up of dust in the cooling system of the laptop. For this try a can of compressed air you can purchase at an electronic store or office supply store and blow the dust out of the system blowing into the vents and into some of the removable panels on the bottom of the laptop. The 100% CPU usage can also cause overheating, slow system performance, and short battery life. In this case I would recommend doing a Full Factory Restore from the recovery partition on the laptop which will wipe out many problems the previous owner left you. Then uninstall factory included programs you will never use, The do a full set of Windows updates (as many as it takes to get it up to date). Then install a LEAN antivirus program like Avast or MS Security Essentials.
I am recommending a full factory restore since I do not know how you "I decided to change it to windows home premium". Any CLEAN install should be good as long as you follow this up with a complete driver install, but the factory restore wipes the drive and includes all drivers on the reinstall.

If the CPU is running hot & you're getting a cooling fan error, why would you think reinstalling Windows would fix anything?
