HX1000W "knocking" noise

Hi All,

 

Just built a new rig but having problems with the PSU. When mounted with the fan facing down, there is a "knocking" noise after a few minutes (once warmed up?). It sounds like something is catching the fan every revolution or a bearing is not aligned. I've checked nothing is protruding into the fan blades & also realigned the fan grill/loosened the screws.

 

When mounted with the fan facing upwards it's a lot better - still there but very, very faint. However, in this position cable routing is a bit tight. I've tried running the paperclip test with the PSU out of the case but problem remains.

 

Anyone have any ideas what it might be and/or a cure?

 

Thanks in anticipation.

It doesn't sound like the knocking noise is a functional problem with the PSU, but if the noise is loud enough to be bothersome while using the system then lets get it replaced. You can use the On Line RMA Request Form and we will be happy to replace it. Be sure to check the box that says “I've already spoken to Technical Support and/or RAM Guy.”
