Hi guys.. sorry im a newbie here..

Im new in Dell.. and currently i have a problem with the fans, noise banging loudly. I just bought it about 1 month ago somewhere lowyat shop. In addition, the laptop is currently not here but in new Zealand. So i had few questions that need your attention:

1. Do I bought on authorised retailer, coz Dell NewZealand asking about
my retailer in Malaysia?
2. Do my warranty 1 year cover globally?
3. Are there any differences in the procedure of having technical
support?

tq
