Some Corsair RM Series PSU's are exhibiting a rapid tapping noise

Our power supplies utilize a clear sheet of Mylar (a type of plastic) to divert intake air to where it is needed the most. We have recently found that some units manufactured in the seventh and eighth week of 2015 shipped with a Mylar sheet that is a thinner gauge than what is typically used. The result of this is the possibility for the Mylar to vibrate when air travels through the power supply. This vibration will cause a rapid tapping noise that may be undesirable to the end user. The issue has been corrected, but there are a few units that made it out into the channel.

If you are experiencing a ‘tapping’ type of noise when your fan is running, please be assured that this is a known issue and that doing an RMA will most certainly resolve the issue. The PSU is still safe to use until a replacement can be provided.

Fair play to Corsair for announcing/fixing and sorting this etc.

Yep, credit due for admitting something went wrong before there has even been any noise about it (or if there has been I missed it!) rather than just fixing the production mistake and pretending it never happened.

Thanks. Yeah, I personally think that it's better that we make it public right away, some sort of transparency always work out for the better
