All your doing is opening up the case, removing the screws on the door to check to see if the fans are spinning and if they are spinning the right direction. Trust me when I say its a cakewalk for that kind of thing. What you need to remember is that back and top fans vent heat out, bottom and front fans pull air in. If one of them is doing the opposite of what its supposed to do, all you need to do is remove the fan and literally flip it around to reverse the direction.

As for your hard drive issue with your personal files, keep them either on the cloud or on a removable storage drive. I typically have 2 hard drives in my computer. My first is my boot drive, where its only purpose is to store the operating system and boot Windows. The second is my storage drive where I keep everything. If for some reason I have to bring it to a repair shop, I can just unplug the storage drive so they can't access my personal files, but mostly everything is on the internet so I don't usually need that.
