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.

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?

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.
