Alienware Aurora R6 PSU Clicking Noise

​The PSU fan is making clicking noise. It started one month ago, in the beginning it was doing that occasionally but now it makes that noise almost all the time. It should be a mechanical issue of the PSU fan, maybe not spinning evenly and thus interfering with some internal parts.​

​This problem was also mentioned in a previous post, and it seems that a replacement of the PSU unit manufactured by another supplier is a quick fix. As mentioned by ​​Alienware-Rodrigo​​‌ in that post, I'm making a new post to get through the user validation so that I can PM him or other people that might be able to help.​

​Thanks.​
