I'm using a Papst fan ( 8412NM ) on my Alpha 8045 & tonight, my system shut down for no reason. When I powered it back up, it started beeping so I shut it down straight away. Upon inspecting the inside, everything seemed fine so I decided to power it up again. I was taken straight to the monitoring section of the BIOS where the "CPU FAN RPM" was flashing in red, & by all means it should be since it was reporting 0 RPM. The wierd thing is that the fan is actually running as it always does. CPU temp is the same. It just stopped reporting the RPMs for some reason. I tryed plugging it to different FAN plug on the mainboard ( CASE FAN, PSU FAN, etc ) but still no RPMs. I don't really feel like buying another one ( 20€ ) & this one is no longer under warranty.:rolleyes: Any ideas on this situation ? PS. I checked the wires on the fan & all three seem normal. None are disconnected.
