Alienware Aurora R6 PSU Clicking Noise

​Had my Aurora for ~a month. 2 days ago it started to produce a clicking noise from the PSU which sounds the same as in the video posted in this thread:​

​The only difference is that the noise is intermittent in my case, probably due to the fan speed in the PSU?​

​Can anyone help me with this? Many thanks in advance!​
