Damn Dirty Ape Posted September 11, 2009 Share Posted September 11, 2009 Brand new HX850, and when powering off the last 2 seconds or so you can hear a noise from the fan not unlike a stick on a picket fence being dragged along. It's not really loud, but I have tried getting a replacement from the vendor and it still persists. There is nothing touching the fan grille or the like, nothing obstructing. Just like a 'b-z-z-z-z-z-z-z-z-' then silence as it stops. I have found it to be the PSU fan by process of elimination. If you have your fingers lightly on the PSU case you can even feel a tiny bit of vibration when this happens. Really puzzled by this. Link to comment Share on other sites More sharing options...

Damn Dirty Ape Posted September 15, 2009 Author Share Posted September 15, 2009 By loosening up the fan screws a little should take care of this noise. Hi If you are speaking of the 4 that also hold down the fan grille, it's not those screws that are causing a problem by being too tight. I went ahead and took the 4 out, lifted up the fan grill and spun the fan with my finger and heard the same noise. This is present in 2 of them. No obstructions on the fan. Any other thoughts?
