Bought my Aspire One yesterday, Its the 8.9", XP/160gb version. I love it so far but im having a problem with the fan. On startup this morning it made a loud grinding noise which quieted off within a few seconds.. but since then the fan has a constant rattle to it, I can make it worse/better by tilting the whole machine fore and aft but it hasn't gone away(ive also tried rebooting, letting it cool off for the day etc.) Im guessing my only option is to return it for a new one but is this a common problem with these? Basically the stores policy(futureshop) gives me 14 days to decide if I want to keep it or not or return it, it came with a 1 year warranty from Acer so I have 12 days basically to decide if I want to stay with the Aspire one, any one who has had this issue or heard of it please let me know how to resolve it or the odds of getting another one with the same problem. Ive read up on the fan control software and the bios upgrade but this is not a problem with loud wind/whirring from the fan(for me that was not bad at all), it sounds more like a faulty bearing or bushing, the keyboard is vibrating as I type this
