The MB has five 4 pin fan connectors on it. Three of the five fans I have attached have speed control lines, the other two do not. Here are the fan attachments: MB Device CPU_OPT PSU Fan CPU_FAN Coolant Pump CHA_FAN1 Rear Fan #1 CHA_FAN2 Rear Fan #2 CHA_FAN3 Coolant Fan When I detached Rear Fan #2,`sensors` suddenly started reporting non-zero values for fan1 and zero for fan2. When I reconnected Rear Fan #2, all three started reporting. When I then disconnect Rear Fan #1, fan 2 stops reporting again. If I remove the coolant pump lead, fan1 drops to zero again, and does not come back when the coolant pump is reconnected. Reconnecting it seems to have no effect, nor does pulling Rear Fan #1 at this point. Pulling both Rear Fan #1 and #2 winds up with fan1 and fan 2 being sero. At this point, pulling the coolant fan causes all three to be zero. Now reconnecting Rear Fan #2 causes `sensors` to report fan3 is spinning. Adding Rear Fan #1 brings up fan2. Reconnecting the Coolant fan at this point has no obvious effect. After reconnecting the coolant fan, adding back Rear Fan #2 drops out fan2, and adding it back causes fan2 to once again report, but this time fan1 remains zero. On a different note, disconnecting the coolant fan does seem to cause the k10temp sensor to rise, which suggests it may be the CPU (the fluid cooling system cools only the CPU). OTOH, the readings are not stable, which they surely should be. Repeated calls will occasionally cause the reported temperatures to jump from the low teens to the mid-to-high 20s. This is very reminiscent of the behavior that caused me to get rid of the old CPU and motherboard. After the coolant failed one day, the temps of the CPU soared to over 100C, and it was then I noticed erratic reporting of the temperature. The only other likely candidate I see for the report is the VGA card. It is the only PCI device plugged into an expansion slot. _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
