I got this computer because I thought the service would be comparable to HP but from the sounds of it, it is quite a hassle. If your fan is grinding, then it sounds like something is wrong and should be covered under warranty. I don't think it's fair that you need to repair the fan on your own. Unless you can "upgrade" to a better fan. The factory fan "problem" was that it was on high when the temperature was only at 40 degrees. After the BIOS update, the fan speed was low and gradually got higher when you started hitting 60 degrees or more. The most recent BIOS update 1.10, allows you to further change the setting to "silent" mode so that it will only start turning on at a higher degree. When I tested it, it did not turn on around 50 degrees. So basically it was set to a higher temperature. I may have misunderstood your problem but if you are saying it's a gridning problem, then that would probably need to be replaced asap. Good luck and keep us posted.
