Since I am running Intel's D845BG MotherBoard which has Intels SMBus and Intel developed a very nice monitoring application called Intel Active Monitor. It tells you all of your Processor Core Voltages, PSU Voltages, System Zone and CPU Core temps and supports up to 2 fans (the board only supports RPM readings on 2 of the 3 pin connections). I have swapped fans around a hundred times before, when I installed my new CoolerMaster Fujiyama Heat Pipe HSF it had a 2500 RPM silent fan and it ran alot cooler than my old HSF but I still wanted more. So I took the 6000 RPM 46 CFM fan off my old HSF and bolted it onto the new HSF. When I plugged it in I also did some other tinkering. I removed my GeForce 3 Ti200 Card and my Wilamette's heat sink. I tore the HSF off the GeForce and cleaned the core and HSF and applied Arctic Silver II and did the same with the Wilamette Heat Sink and reinstalled everything. When I booted the system back up I got an error on Active Monitor that said one of my fans had reached 0 RPM yet all of my fans were (are) working. I read through the Intel documentation and it says that occasionaly when you change fans you may have to reinstall Active Monitor. So I did that assuming it would remedy the problem. No such luck. I have only one fan showing in Active Monitor now. I did remove the 3 pin connector from the fan so that I could get expandable nylon and heat shrink onto the wires but I made damn sure that I have the wires proper orientation noted. I also made certain that the connectors were installed back into the clip right side up and that they would make contact with the pins on the mobo. Still no luck. I guess my best bet is to plug another fan into that port and move the CPU fan to the other port and see what happens.
I hope that you just didn't reinstall it, because you MUST uninstall it first, or it won't work. Glenn
No, but even the best of geniuses can be absent-minded at times. Can you switch the fan plugs and/or try another socket, just to see if it will come up? Glenn
high-draw fans + mobo fan header == bad you may have fried the fan header that's registering 0 rpm, in the future consider using a 3-pin to 4-pin adapter and connecting the fan directly to one of the power leads from your PSU, i think the molex connectors are rated at 6 amps so there's zero chance that you're going to kill 'em
Drew, Nope the Fan Header would not have been fried from the fan. It is well within the Fan Headers half an Amp (.50) max amprege draw limit. Plus this is the fan that was running on that headder from day one. I am going to switch fans around and see what happens.
