Title: How To: Fix Rattling Fan Noise on BFL Single Post by: mrb on July 28, 2012, 07:47:51 AM Some BFL Single units make a rattling noise. This is in the majority of the cases caused by the smaller fan (enclosed in a copper/silver heatsink) that is touching the case. One very easy solution to fix the problem is to insert 4 screw washers between the bottom standoffs and the bottom side of the PCB, in order to increase the headroom between the fan and the case. I myself fixed 3 of my 10 units this way:

Sheesh, anything to make a buck :D Title: Re: How To: Fix Rattling Fan Noise on BFL Single Post by: WhitePhantom on July 28, 2012, 05:46:46 PM What? Just go to the local hardware store and buy some for about 10 cents. At least it's good info. I figure if anybody gave him a BTC for the washers, it'd be more like a tip for the help than anything.Sheesh, anything to make a buck :D Title: Re: How To: Fix Rattling Fan Noise on BFL Single Post by: bitcoindaddy on July 30, 2012, 06:33:28 PM I think BFL just got some free engineering advice.
Title: Re: How To: Fix Rattling Fan Noise on BFL Single Post by: CrazyGuy on July 31, 2012, 03:27:47 AM I had to do the same with mine. My rig already had a nylon washer between each the front 2 spacers. I added 4 all together and the fan is no longer hitting the case. I suppose I could have just bent the case out a bit to accomplish the same thing. One thing to note, any more than 2 nylon washers and you will probably not be able to get the USB and power jack lined up.

Also I believe somewhere the BFL guy said that it was ok to work on the fans as long as your were careful (ie not voiding warranty). |
