100% you should contact support they will help pin down the issue and if you are still in warranty they will send you replacements for any defective parts.
With that said I would try two things before replacement:
-
Check the fan power plug is fully inserted (for the tilting effecting speed) this is assuming your temperatures are not the reasons for the fan ramping up.
-
Remove the fan and check for foreign object (for the odd noise). To do this requires removing the motherboard to access the 3 screws on the underside of the fan as well as the two captive screws on the top side and some tape, I just made a post about it here.
