I am in desperate need of some assistance. I have had two Northbridge\nfans so far. One died completely and the other is on its way. As\nsoon as the speed goes below 2000rpm, the siren goes off. And then\nit shuts off as soon as it goes above 2000 rpm. I would love to\nreplace the fan with a Zalman heatsink but it seems I cannot. If the\nfan is disconnected from the MOBO, then the siren keeps wailing.\nAnyone no how to get around this. I have already disconnected my PC\nSPeaker connector so I don't hear it but that is a jury rig more than\na fix. I'd appreciate the help.\n\nThanks,\nJim\n\n==============\nPosted through [URL="http://www.HowToFixComputers.com/bb"]www.HowToFixComputers.com/bb[/URL] - free access to hardware troubleshooting newsgroups.
