Ahtlon Posted December 16, 2015 Share Posted December 16, 2015 So today I heard a strange noise coming from the PC, I had installed new fans and throttled them back so that they only make 600rpm, now the pc is silent :cool:, except for a strange ticking/knocking sound.:confused: Took al panels of the 900D so I could hear were the sound came from. It's the AX1200i that is making this sound.:mad: Never heard this sound before, but now the pc is silent I can hear it and it's every 22 second that it make that sound. I can hear it even when the case is closed. It's a annoying sound and it's not pleasant to hear it every 22 seconds. What To do. I finally got my PC silent and now have this knocking sound. Even when my old HDD is working I can hear the knocking sound of the AX1200i above the HDD.:mad: The AX1200i is now 2 Years old. Link to comment Share on other sites More sharing options...
leftshark86 Posted December 16, 2015 Share Posted December 16, 2015 This may be the PSU fan checking for obstruction. While this action is normal, it shouldn't be making an audible sound. A temporary solution may be to manually set the fan speed to 40%. Alternatively, you could replace the fan or PSU. It should still be under warranty if you want to replace it.
