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.

  • 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:

    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.

  • 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 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

  • 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 Connector

    I hooked my Enermax fan connector up to my motherboards PWFAN1 connector. I started up PcAlert4, and it reads out 0 RPM on my PSU fan. So, I switched it over to PWFAN2, and my computer wouldn't boot! Back to PWFAN1 and it boots fine again, but I get a 0 RPM reading on the PSU Fan. There's a temp sensor on the PSU, is it just not turning on the second fan because it doesn't need it? How do I know for sure that the PSU fan is hooked up right and working? The PSU came with a connector so I can just plug the fan in and have it always on. I'd rather have it always on and know it's working then 0 RPM and potentially not working. Anyone have any thoughts?
    Thanks,
    Dave

    My Enermax has two fans. One is always on, the second one is motherboard controlled (or is it simply motherboard MONITORED?). Is the one that's always on the one on the bottom, or the one on the back of the PSU? I just went to Enermax's website and manged to dechiper enough of a broken english FAQ to read that some mobo's read out 0 RPM even though the fan is up and running. I'm still gonna check that both fans are spinning tonight. I know the one at the back is, I can see it, haven't checked the one underneath.

  • 3-pin Fan Sensor

    I have a Neo4 Platinum with an Antec NeoPower 480W Power Supply.  This power supply comes with a 3-pin fan sensor.  where on the motherboard do i connect this 3-pin fan sensor???

    Any free 3 pin connector [EDIT] as the poster below says not all can monitor fans speeds. Though note you don't have to install it - it's just for monitoring the PSU fan's speed.

  • 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.

    Make sure you have a 3-wire fan connected.
    You may also need to increase the fan divisors.

    solved
    1)
    install with pacman:
    lm_sensors
    yaourt
    sudo
    nawk
    refer to the wiki of archlinux to install and configure this packages
    2)
    save this script and  add it to startup and shutdown of kde settings (i assume you are using kde,and i suggest you to install it)
    (example sudo path/to/yourscript.sh)
    #!/bin/sh
    ### controllo ventolina
    ### controlla in automatico la velocita' della ventolina data la temperatura
    SENSORS=/usr/bin/sensors
    PATH=/bin:/usr/bin:/sbin:/usr/sbin
    test -x $SENSORS || exit 0
    sudo sh -c "echo 1 > /sys/class/hwmon/hwmon2/device/pwm1_enable"
    while [ 1 ]
    do
    ## prende la temperatura da lm-sensors
    t1=`$SENSORS | nawk '/temp1/ {print substr($2,2,2)}'`
    if [ $t1 -gt "49" ];
    then
    echo "180" > /sys/class/hwmon/hwmon2/device/pwm1
    echo "temperatura $t1 gradi \n" ##comment this lines if you don't want to run in console
    sleep 20
    elif [ $t1 -gt "47" ];
    then
    echo "170" > /sys/class/hwmon/hwmon2/device/pwm1
    sleep 20
    echo "temperatura $t1 gradi \n"
    elif [ $t1 -gt "45" ];
    then
    echo "157" > /sys/class/hwmon/hwmon2/device/pwm1
    sleep 20
    echo "temperatura $t1 gradi \n"
    fi
    done

  • 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.

    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 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:

  • 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

  • Speedfan will not turn my psu fan speed down

    I,ve put everything on automatic and followed the instructions from this forum, butthe PSU fan keeps going at 4800. Anyone got any good solutions?
    Both fans put on 1% min value and 100% max.
    Temp NB: desired 67C, warning 75c
    System: des 40,warn 50
    cpu: des 40, warn 50
    What to do, what to do???

    Cnotemd - not strictly true.  Enermax makes PSUs with manual fan speed control (such as mine - see sig) and also auto control via mobo temp monitoring.  Check out the Enermax website for further details.
    It's a useful noise reduction feature to be able to control PSU fan speed if heat dissipation is not a problem.
