PSU fan connection

My PSU has a 3-pin fan signal connector. Its labelled PSU fan monitor connoctor. Is there anyway I can connect this the mobo so that it can be monitored. I tried connecting it to S_Fan2 but I suspect this is for powering a fan, not monitoring.

if you got a passive northbridge cooler, just use that connector on NB_fan1 (or something similar named)
It'll then show up in corecenter under NB fan speed like this:

  • C200 M1 PSU Fan speed varies

    I have a C200 M1 running 1.4(3p), I am noticing some performance issues with this server, it just seems slow.  I went to it physically and you can hear the PSU fans spin up and slow down every few seconds.  Within an SSH to the CIMC I am seeing both fans vary from 2K to 7K RPMs every 3-5 seconds.  Here are the PSU details:
    ucs-c2xx-m1 /chassis # show psu detail

    This server was running firmware 1.0(2) when I first found this issue, I have since upgraded it to the lastest code.  I have done a full shutdown and removed the PSUs and let it sit for a few minutes.
    When the fan speeds are low, the CPU performance is very low, VMs running on it are slow.  Any thoughts??
    Thanks.

  • Msi pro-e mb possibly keeping psu fan on?

    Hello all, fresh i7920 build with msi pro-e mb, corsair xms3 6gb, and a corsair tx750w psu.  The problem i'm having is when i power down the system for the night the psu fan will continue to run all night long even though the system if off(not in sleep or hibernate).  I am guessing its the psu or the mb or maybe even a bios setting i'm overlooking?  Any suggestions or feedback would be greatly appreciated, thanks in advance.

    Hmmm,  Another experiment to try.  Turn off the system and do what I said before with unplugging the PSU and draining the capacitors.  Now, unplug the SATA connector to your HDDs and the Power connectors to the HDDs.  You can leave the ODDs connected.  Re-plug in the PSU with no HDDs connected or powered.  Turn on the PSU and turn on the computer.  You should get a blinking cursor or some message.  Turn off the computer by the power switch.  Does the fan still run?
    If the fan still runs, do you have access to another computer or another PSU?  You could try this PSU on another computer, yours or a friends to see if it does the same thing, or borrow another PSU and see it that fan runs on your PRO-E when the machine is off. 

  • PSU Fan Speed Monitoring

    Power supply fan speed shows zero in BIOS and Speedfan software.
    Same zero result when fan signal connector is attached to PWRFAN1 or SYSFAN1.
    Visual inspection shows PSU fan is spinning.
    Fan speed 1 and 2 work fine.
    How do I get fan speed 3 in Speedfan and/or bios to show the PSU fan speed ?

    At least on my mobo, there are only 2 connectors that can monitor fan speed, CPUFAN1, and NBFAN1. The other 2 connectors, SYSFAN1 and SYSFAN2 , can provide power to run fans off the MOBO but do not have the ability to "sense" speed or control the speed.. I only have the CPU HS fan connected to the MOBO and the sensor wire from the PSU attached to NBFAN1. All other fans I have connected directly to the PSU.

  • PSU Fan and NB Plug

    I know this has been talked before BUT.. I just got a new Enermax PSU and I have connected the 3 wire fan connector to the NB plug on the mobo.  The concern I have is that the PSU controls the fan speed, but I thought the NB plug ALSO controls the fan.  Is there going to be some sort of conflict?  I have the SMART NB fan temperarture in the BIOS disabled.  Is this correct or can there be a problem?
    Thanks,

    Thanks,
    what you also could do is place that connector to S-fan1 or something and get an old connector from an old fan and take the two wires on the left and right, rip out the center one, and connect those two ends you ripped out of the old fan and connect them to the corresponding wires on that S-fan1 connector, and plug it in to the NB-fan connection
    This way it'll draw power from the S-fan1 connector, and the speed won't be changed by the board, yet you'll have the speed wires on the NB fan so you can monitor them in corecenter
    Getting to be a bit more work I ma willing to spend time on.  I disconnected the NB connector and zip tied the wire.  I really don't need to monitor that fan since I am not OC'ing.  It was more a "nice to have" than a "need to have".  

  • Where should PSU fan connector go?

    Damn, feel like a total noob for asking this question even though my system is already built and running fine. The manual does not explicity say where the PSU fan connector can/should go so i have three options, the NBFAN (not used since i have a waterblock on it) that has a sensor, or the connectors for the system fans, or cpu fan. Other boards i've used usually have connectors labeled for the PSU, but not my Neo2 Platinum. I connected the PSU fan to a system connector and decided to use the NB one for a case fan. My question is there any danger of connecting the PSU connector to the CPU connector? I have a waterblock on the cpu so the connector is not being used and it would come in handy because of the sensor.

    I never hooked up the psu's fan connector to any motherboard, I really never found a need to monitor the psu's fans and thats what its for. I dont think anything can be harmed since it can work without even being connected, but dont hold me to that. Someone with more experience in the psu area may be of more help. Interesting question.

  • PSU fan noise

    very loud noise, intermittent, coming from PSU fan, as well as noitceable reduction in outgoing airflow. verified noise source by stoping the PSU fan.
    does anyone have information about how to access this fan? there are 2 tiny ellen keys on the outside of the Mac back case where the PSU is. inside the PSU is connected with multiple bolts inside. i could not find any description of how to open the PSU and access the fan.
    My Mac is 6 years pld. I believe that cleaning it and a tiny drop of lubrication may fix the problem. Does that make sense?

  • MSI KT4AV and PSU FAN connector?

    MSI KT4AV has 2 fan connectors: CPU FAN and System FAN. What about PSU FAN - is there PSU fan connector on this mobo? Can I connect PSU Fan to System Fan connector?

    I've read that PSU Fan is not powered from Fan Connector, but it's only uses it to measure RPM of PSU Fan. RPM of PSU fans is controlled by PSU (Chieftec 360W HPC-360-202 DF). Is amperage so important in this situation? Sorry, if it's lame question but I don't know too much about PSU's. ;-)

    I got the MOBO and CPU for a Friend of mine. She got her husband friend to set it up and had problems getting it to power up. (He works for the local council in I.T so he know his stuff even if it mostly older hardware) I asked them to try a different PSU (ColoursIT) as the ones they had was 12V @ 13a and 12v @ 15a
    Well no joy so I took it back to try myself. After trying in 2 different cases (with the above hard ware) inside and out side. I can’t get it to POST. The weird thing is all the PSU fan spin when connected even if the front panel connectors are not connected. When connected the same happens but the power buttons have no effect. I know the buttons work it happy to power up my old XP chip.
    The CPU fan won’t spin when connected to MOBO CPU fan header. But using a 4 pin to 3 pin fan adaptor it does. Reseated the CPU had the same outcome (all the pins look fine). I’ve tested all the RAM (one @ a time) and PSU’s in my rig (in sig) all are working fine and boots the system into winxp and all the rails are with-in 5%. The GFX’s I’ve got an old AMD 1800 XP tested and working.
    On some MOBO with damaged CPU you normally get beeps. An asus socket 754 I had over a year ago use to give audio warnings when POST’ing e’g CPU not installed, GFX not installed. I get no Beeps from the K8MM3-V. Their no option to connect a D bracket (even though its not supplied)
     Tried resetting CMOS and removed the battery for 8 hours and replaced it, also with another one.
    I think the MOBO dead but it mite have taken out the CPU as well. I’ve got no other 754 to check it with.
    Ideas ?

    Hi!
    Nice to see that some people realize that giving full specs is very important! 
    You did quite a lot already, so that leaves not much to suggest. The only thing I can think of now, is to check the CPU: is it installed correctly? Then you can take the board out and lay it on a piece of cardboard. Leave the CPU, leave one dimm and the vid card. Clear the CMOS again, connect the PSU and try to start the board.

  • Mac Pro 1.1 How to control PSU fan

    Dear Users
    I have an upgraded (2 x X5355 8 core) Mac Pro 1.1 running 10.7.4. I routinely use SMCFanControl (the latest version) to ramp up the fans when I am running long, CPU-intensive jobs. However, SMCFanControl only changes three of the four fans - the PSU fan remains stuck on 600rpm, regardless of the settings. My PSU is getting pretty hot - 70+C, so I am looking for a way of cranking it up. Any suggestions will be greatfully received.
    Thanks BB

    That's a good question. It's been a while since I've run my 1,1 Mac Pro, but I remember that smcFanControl could change everything but the PS fan (which is at the front of the PS brick, right behind the DVD drives - I just took the cover off and doublechecked). On my current Mac Pro, which has the same DVD/PSU layout, smcFanControl can control all the fans.

  • MDD PSU FAN REPLACEMENT

    A question thats been beat to death but i'll ask anyhow. I have a Dual 1GHZ MDD. I got this as a gift and the original owner never took part in the silence swap way back then. So it is a LOUD beast. I have just done my first cooling mod. My Idea was taken from XLR8your mac. Here is a few pics of my setup.

    http://i7.photobucket.com/albums/y286/Kissfan74/DSCF0121.jpg
    So my question is, What are good replacements for the 60mm psu fans? I have the original stock Deltas which move ALOT of air( 37cfm at 49) Which is MAJOR loud. I've searched everywhere for tips ect. I've even seen where a guy took some Volcano5s and used those fans. He has them rated at 32 cfm but that is wrong it's more like 24 cfm for those. So what would be the best and safest fans to replace the originals without hurting my psu. It gets really hot inside there and I don't wanna under do it . Any tips are welcomed.
    I found these:
    http://www.directron.com/ec6025.html
    They look like just what I'm after. The CFM is lower then the stock fans but the noise level is less then 30. With my Case mod I think I can keep my temps low near the psu and have a quite machine! Are these fans good enough???? Thx in advance!!!!

    So my question is, What are good replacements for the 60mm psu fans? I have the original stock Deltas which move ALOT of air( 37cfm at 49) Which is MAJOR loud. I've searched everywhere for tips ect. I've even seen where a guy took some Volcano5s and used those fans. He has them rated at 32 cfm but that is wrong it's more like 24 cfm for those. So what would be the best and safest fans to replace the originals without hurting my psu. It gets really hot inside there and I don't wanna under do it . Any tips are welcomed.
    I found these:

    They look like just what I'm after. The CFM is lower then the stock fans but the noise level is less then 30. With my Case mod I think I can keep my temps low near the psu and have a quite machine! Are these fans good enough???? Thx in advance!!!!

  • Direction of PSU fan in Quicksilver

    I just recently replaced the power supply fan on my 733 quicksilver, but i am not sure if i put it in correctly. the fan acting as an intake fan and sucking air from outside the case and blowing it inwards. is this correct or do i need to flip it around? any help please!!
    Quicksilver 733mhz, iBook G4 1ghz   Mac OS X (10.4.8)  

    Hi
    With the Quicksilvers the PSU fan and large case fan exhaust warm air whilst the CPU fan intakes cool air. It sounds as if you may have installed the PSU fan the wrong way around.

  • Psu fan sensor

    i have a new psu which has a wire for the fan sensor with a 2 pin plug attached but i cannot find anywhere to plug it into on my k7n2 board.
    my question is  am i blind or does this not need to be attached to the m/board being that the 2 fan points on the m/board are already being used
    thanks in advance

    I've just upgraded my PSU to an Antec unit. I've a few Q's of my own and thought i'd tag along rather than start a new thread.
    My MSI Supplied PC Alert software has displays for System Fan , CPU Fan And PSU fan can i presume that the fan that is sitting on my Northbridge Chipset is supplying the System Fan speed.
    Would it be OK to run the northbridge fan via a spare molex+adaptor and plug my Antec PSU sensor wire into SFAN1. I would think it was more important to have the CPU and NB fans on constantly and let the PSU vary the case and PSU fans - any idea's on this ??
    I Think that the Antec PSU has a certain amount of logic built in and can vary the fan speeds depending on the Temp , does anybody know if it can do this independantly (with an inbuilt temp probe) or does it need to be plugged into one of the MoBo Fan pin-outs.
    I can't get over just how quiet my computer is after fitting this new PSU , i keep checking to see eveything is still whirring away, it's so quiet. The (brand new) Fan supplied with my CPU is a right rattler when it starts up, it is easily the noisiest fan on the machine, possibly noisier than the 5 other Antec fans put together !
    Sorry if these Q's are a bit basic , i always think it best to ask before frying anything.

  • No PSU fan

    My KT3 Ultra 2 does not see my PSU fan.
    I have tried PC Alert 3 and 4, as well as speed fan.
    It simply is not there.
    I am using bios 5.6.  5.4 was supposed to support low rpm fans.
    Anyone have this same problem or know a fix?
    Thanks,
    J. :P

    Thanks Brad.
    I guess I should have done that in the first place.
    I just assumed, because it worked on the 266a that it would on this board as well.
    J. :P

  • PSU Fan Moniter Connector

    I have a Antec True550 EPS12V 550W power supply, I am curious about the blue/back wire ... it says PSU FAN MONITER CONNECTOR. It's a 3 pin connector. Does MSI 865PE support this? I wonder, since the power supply has auto temp controller for salience.

    But it will Not Speed up or Ramp Down Without you Adjusting it Manually, as there is No thermal sensor , The Only thing that it will do Is Report the PSU'S Fan Speed in RPM'S...But If the NB Fan Header did have a Thermal Sensor (Or the Best would Be The Sytem Fan Header But this Lacks even the Speed Monitoring Function as it is only 2 Live Pins) But if they Both Had Thermal and Speed Sensors, that Would Make these Boards Absolutely Complete, As That Is My Main (and Only) Gripe about these 2 Boards, is the Lack of Fully Functional Fan Headers, and Put 4 of them On the Boards, Like almost everyone else does, Not that I use them as I Use my PSU to Power my Case Fans, But it would be Nice just in case I decided to use them, and for the people that do rely on them......But I have Already Suggested this in the MSI Survey..............Sean REILLY875
