Alienware aurora CPu fan not working

Hi there,  in first place im Italian so sorry for my terrible english.

My current problem is related to the cpu fan which is not working for some reasons, so everytime i try to turn the pc on im getting the message CPU Fan fail warning.

In fact the liquid cooling isn't working for real and by cheking the bios temp i can clearly see the cpu temp going up over 90c.

Im wondering if there's anything i can do to fix this problem or if im a supposed to send my computer somewhere or i am supposed to buy a new cpu fan , if so which one? Also any help would be realy appreciated

My system i not even a month old so if i can send the pc somewhere to fix it i'd like to know where and how  i can get the address of this place.

Regards.
