Hi together, like described in the other thread, I've just purchased an SP3. I'm from Germany but I bought it in Austria 'cause I got it for an unbeatable price from there. I received and unpacked it yesterday, so it's brand new. Although it's actually a wonderful piece of hardware, I'm very unhappy due to the fact that the fan makes some very untypical RATTLING NOISE like can be seen in this video: It's not that distinct, but I think that's not what it should sound like and mine has the same bearing failure. Now I'm not sure which of both is the better procedure: 1.) Returning it back to the dealer. I think I would get cash back because they don't have the SP3 in stock any more. 2.) Requiring a replacement device from Microsoft. Maybe they will send me a refurbished one and that won't be satisfying!! Do you see any way to make sure I get equivalent substitution?? Does MS still have new SP3s in stock? When I log in to the Microsoft support page, I see 2017-12 as end of guarantee. Microsoft gives 2 years of guarantee. How is this possible? It should be 2018-06! I'm very sorry for bothering you with all my questions. Tried to get a call from MS support twice this morning but nothing happened.
