ASUS Probe - No chassis fan/power fan reading
I've got an ASUS P4C800-E Deluxe Motherboard with a case fan attached to the PWR_FAN connector on the motherboard.
Can anybody explain why I do not get a reading on ASUS Probe (reads temps, voltages and fan speeds) under the Chassis fan or Power fan reading? When using Speedfan, I get a similar absense of this reading.

put a multimeter between the rpm line and gnd while fan is in operation (use alligator clips and pins on the metal 'fingernails' of the 3 pin plug)
you could use voltmeter or probably even ohm-meter and see if anything is 'happening' there. if it has rpm monitoring there will be something happening (my multimeter won't stabilise on a reading but this tells me the wire isn't just dead)

Fair enough, that was the type of logic I was looking for.sthayashi wrote:Almost no low speed Panaflos w/ RPM support exist. I have never seen one for sale anywhere, so there is a 99% chance that your L1A doesn't have RPM support and that's why Asus probe isn't detecting anything.
I'm not really into sticking my voltmeter into the machine to see if anything happens, too worried about shorting something else out in the process.
yer 99% "logic" can't settle the question like a multimeter can
my panaflo L's have only two wires so i know they aren't rpm monitoring. i can't think of any good reason why panasonic would also manufacture three-wire non-rpm monitoring fans?! sounds like the cost-engineers were havincg a day off there
lol that's why i use pins.. you have to be something special if you can manage to connect two contacts together using the nib of a pin.postul8or wrote:I'm not really into sticking my voltmeter into the machine to see if anything happens, too worried about shorting something else out in the process.

Simple. No one wants or needs them and they cost a small amount of money to produce (money that can be saved if they don't make them). Part of the reason no one wants or needs it is because RPM detection is flaky below 1500 RPM (or so I've heard).wim wrote:i can't think of any good reason why panasonic would also manufacture three-wire non-rpm monitoring fans?! sounds like the cost-engineers were havincg a day off there

Fair enough, as you say in another post (http://forums.silentpcreview.com/viewtopic.php?t=14195), you simply need to look for a BX at the end of the model number.Ralf Hutter wrote:This topic has been covered very thoroughly several times here at SPCR.

I thought something was broken because when I bought my low flow Panaflo it came with both a 2 pin and 3 pin cable. I just assumed it came with a 3 pin because it was ready to go with rpm monitoring.
Not really a big deal, I don't think I could throttle down rpm much anyway because my CPU (P4 2.8C) runs at about 60 C @ 100% CPU usage in my current config. If I take the side panel off it goes down to about 48 C, clearly I need to pump as much air away as possible and possibly re-work some things in my case to improve things.
