This is a nice looking machine, but mine became very noisy after about one month of use. I thought it was the fan because it did cycle up from time to time. HP Support sent me a fan and I replaced it, but the clicking or 'rattling' continues. They suggested a BIOS update which I had already done, so they are now sending a new HDD. We shall see.There is also another issue with the audio driver where the bass completely goes away. This is apparently a known issue with HP models as the internet has a few threads on this regarding the HP Conexant driver. You can fix this temporarily by resetting to default in HP Audio Settings....but it does not stick.
