875P NEO northbridge fan

Hi ,
Wonder if anyone can help, I have an MSI NEO 875P Neo, Ive noticed however that whereas the Northbridge fan used to reach around 4000rpm its now maxing at about 3550rpm ?
what rpm should the NB fan run at , if the temperature is cool does the mainboard automatically reduce the NB rpms ?  also I am using speedfan to monitor the temps
If the NB fan is on the way out where can i get a decent replacement ?

The board does not have an NB temp sensor, so if you use the NB temp to control the fan speed then it will be adjusted according to whatever stray voltage is on the terminals where the NB sensor should be. I used the CPU temp instead for regulation.
If the fan fails, just remove it and leave the heat sink in place. The heat sink alone provides adequate cooling.

Thanks for your reply however sorry, but  what do you mean by stray voltages ? if my rpms have gone down does this mean a problem with my voltages ?

  • MSI 875P Neo-FIS2R Northbridge fan too loud !

    I have a very quite system, but the Northbridge fan is too loud ! In fact it is the loudest element in my system and I'd like to replace it.
    Which fans are there that I could use instead ?

    At 6000 RPM almost every fan is loud.........lubricant doesn't help, it's a shitty fan........
    Loosing the ridiculous disco light is actually another advantage.....

  • 875P Neo-FIS2R northbridge fan replacement

    hey guys...i am somewhat new here. I have browsed the board here and there. I am trying to make my computer quiter but have found that the northbridge fan is very loud. i have read where a lot people of just taken the fan off and left nothing else. this concerns me because i do overclock my computer and dont want extensive heat on the northbridge. i saw a post awhile back about someone found a heatsink tht would fit and replace the northbridge fan on this motherboard. i can not find that post or the type of heatsink. if anyone knows what heatsink will fit i would be grateful. thanks

    Leave the heat sink in place and remove the fan. It's there for looks. Read all of

  • Replaceing NB fan with heatsink (875P Neo-LSR)

    I'd like people's opinion on wether or not you think a Zalman ZM-NB32J North Bridge Heatsink will be enough to replace the NB fan on an MSI 875P Neo-LSR. I would hate to damage the board.

    I have been using MSI boards for a year or so now and the northbridge hsf unit has yet to disapoint me. Do not bother replacing the NB HSF unless it does indeed fail as you will lose your warranty if you replace it.

  • MSI 875P Neo-LSR & Northbridge Cooler

    Hi
    Hi have a MSI 875P Neo-LSR motherboard and the northbridge cooler is making alot of noise!
    I've already cleaned the dust from the fan, added some oil but it stills makes an anoying noise
    My question is this:
    I don't want to spend €€€ in a new cooler because i'm upgrading my system in a few months so, will my motherboard survive without the cooler? But remaining with the heatsink...
    I have a Thermalright XP120 with an 120mm fan in my CPU, which are very close to the northbridge, they might fresh a little the NB... And i got a good airflow in my case...
    My MB:

    Thank you for your answers! 
    Do you know the maximum temperature that the NB can get? Or the normal one...
    I want to test if it's not getting to hot without the fan 

  • Help with Fan Speed/Temperature Monitoring - 875P Neo Series 2.0

    Hi
    My mobo manual doesn't explain the monitoring facilities available on this board and I would like confirmation of the following:
    My P4 Northwood CPU Fan as supplied with P4 is connected to CFAN1 and provides monitoring of temperature and fan speed and also permits fan speed control.
    My Northbridge Fan as supplied with mobo is connected to NBFAN1 and provides monitoring and  control of fan speed.  No temperature monitoring available.
    My mobo provides monitoring of system temperature but doesn't say how this is measured and at what location.   
    There are two other 3-pin fan headers on the mobo; one is labelled SFAN1 with Gnd, +12V and the third pin NC and the other is labelled PFAN1 with Gnd, +12V and Sensor pins.
    My new Antec 500W SmartPower 2.0 PSU has a monitoring cable that is wired with a black Gnd wire and a blue Sensor wire and, according to the Antec manual, is supposed to provide fan speed monitoring if connected to PFAN1 - I have tried this and get no information showing in either SpeedFan or Sandra.   ??? 
    My new Case fan, an Antec SmartCool, also has a monitoring cable but only has the third pin wired, presumably a sensor wire, and presumably could also be attached to PFAN1 instead of the PSU signal connector to provide fan speed monitoring.   ???   Obviously I cannot connect both the PSU and Case Fan sensor cables to the mobo because the SFAN1 connection has no sensor pin connected; I presume this one is just a power supply to a fan as an alternative to using a supply line direct from the PSU.
    Can anyone advise me on the correct use of the PFAN1 and SFAN1 connectors and what they are capable of.

    - System temperature is measured at the Winbond W83627HF sensor chip located in front of your PCI slots.
    - PFAN1 does indeed monitor PSU fan speed if the PSU has a fan speed reporting header.  Not supported by some monitoring software (if Speedfan can't detect it, it doesn't support it.  At least not until Alfredo's next revision).
    - SFAN1 provides power only, no monitoring.
    - Try a different monitoring software and see if it can detect the sensor monitoring your PFAN1.  There are other monitoring software out there you can try, such as the CoreCenter that came with your motherboard, or Motherboard Monitor 5 or PCWizard (though you cannot adjust fan RPM through those programs).

  • MSI 875P Neo LSR Dead??

    Hi y'all,
    Saturday 12th of juli I've bought some components:
    - Intel P4 3.0GHz 800MHz FSB
    - MSI 875P Neo LSR
    - 2*512MB Kingston HyperX PC3200 CL2
    - Hercules 3D Prophet 9800 Pro
    - Iiyama Vision Master Pro 413
    After installing the whole bunch, I tried to boot the system but nothing happend!
    So I waited for about 5 min. and booted again. This time almost succesfull but..... the only parts that were working are my fans (casefans, cpu-fan and the Northbridge-fan).
    The powerswitch wasn't working (and it was installed correctly). I had to power the system via the powerswitch on my powersupply. So my guess was that my mobo was dead!
    After returning the mobo back to my retailler, they concluded that it was dead indeed, so the gave me another mobo.
    So after installing the new board, I tried to boot again, but still no succes so far.
    My retailer tested the board again and it was also dead.
    Some symptoms:
    - Active fans
    - No HDD, floppy and DVD-player/Burner activity
    - Blank screen (display in standby)
    - Instant power on when I turn the switch on on my powersupply
    I've tried different videocards, memory modules and clearing the C-MOS, bur nothing seems to help ;(
    Can you please help me out????
    Thanks
    Best regards,
    Arjan

    With regard to the motherboard stand-offs, motherboards dont always use the same amount or in the same position (the stand-offs are movable -either bending out of brackets in the case or unscrewing)
    Always check ALL the standoffs line-up with screw positions for your moterboard before fitting, a wrongly positioned post can short-out PCB traces/pins
    Another easily overlooked item is the square 4 pin 12v connector (older type power supplys dont even have one), the 12v power connector is located by the northbrige/AGP socket (the CPU will not start without this fitted)
    Sometimes when physicaly altering a computer the reset or power-on (start) switchs dont line up correctly with their buttons -this can cause the switch to be permanently "on"
    The power-on switch will cause the computer to "cycle" (constant restarting) and the reset switch will cause the computer to hang with-out initialising -try removing the reset switch connector from the motherboard
    If none of those are the problem i would suggest trying a different power supply -or maybe your dealer could check the one you are using at the moment

  • New system/Northbridge fan

    Hi all,
    I'm planning to buy some new parts for my machine:
    * MSI K8N Diamond Plus
    * Athlon 64bit 3500+ venice
    * Kingston pc4000 1GB mem
    * Tagan 530Watt PSU
    * Zalman CNPS9500 Led CPU cooler
    What do u think about this configuration?
    And my second question is the northbridge fan, i don't like it :(
    Currently i have an MSI 875P neo, this board also had an annoying NB fan which i've removed because
    it wasn't really needed and it did make allot of noise.
    But is this also possible with the: MSI K8N Diamond Plus board or am i going to fry this one when removed?
    I'm not planning to overclock the system and have pretty good cooling (i think ) in my case:
    Thermaltake soprano case
    2x 12CM fan (front/back)
    1x 12CM fan in PSU
    Thanks in advance!

    Configuration is nice,for PSU look also to my Antec http://www.antec.com/us/productDetails.php?ProdID=24480 or http://www.antec.com/us/productDetails.php?ProdID=28550 because it have cable management and you can install only the cables you need,in 6 years with Antec PSU's never have one single problem.With the northbrige fan look the response that was given to me by a forum member http://hem.legend.se/kammaren/temp/chipgpu.pdf But on my mobo doesn't fit so I use zalman fanmate 2 to reduce the rpm of the fan and now is ok the noise

  • First Impressions of 875P Neo FSI2R

    Hello All, first off i'd like to make some comments about this board.
    My Abit IC7-G needed to be returned, so i did a little research on a replacement as the aforementioned board has its quirks, ( Only wished i'd found these forums before i'd purchased. )  so i decided on the 875P Neo FSI2R as it was the closest to my previous setup.
    Now this board is really pissing me off , doesnt MSI have any quality control ?
    1. How can my WD Raptors work fine on the ABIT board using ICH5R , but the MSI have these damn problems ?
    2. The voltages are far from stable , i set 1.60 in bios and it varies from 1.52 - 1.62
    3. I hope the person responsible for the IDE LED not working on SATA has been taken out and dealt with (THIS IS JUST LAZINESS ON MSI's PART)
    4. this board is much slower than the IC7-G
    5. Its a real shame , i cant use this board i will really miss those northbridge lights.
    6. i have my doubts as to if these problems can be fixed with a bios upgrade so reluctanly i am returning this board for something else ... any suggestions ?
    This isnt meant as a flame or to enrage happy Neo owners.
    Kind Regards
    Amigan.

    As far as the problems with the Raptors on the ICH5R I'm afraid I don't have a definitive answer. Only a few ideas that might help. I have had my Seagate 7200.7 drives connected to it as Raid/non-Raid a few times with no problems. Generally unless I'm playing around I keep them on the Promise controller for better performance(no PCI cards).
    1. I'm not sure how old your Raptors are but the first bunch are known to have had trouble with some motherboards. If you look under the drive at the IDE-SATA bridge chip there is a number on the chip that has the letters "BxP" in it where x is a number probably below 6. Apparently the B3P's and below cause problems in many cases and the B4P's in less cases as well. B5P and up is supposed to be good. There is no fix that I'm aware of. At the very least I would run the WD drive diagnose utility to check for problems.
    2. Make sure the cables are properly secured and not overly bent. No hard 90 degree angles with serial cables.
    3. Perhaps a conflict with other devices. Make sure the "APIC...IRQ" setting is enabled in the Bios to free up more IRQ's in XP. You can also disable serial ports in the Bios (super I/O config I think) for more IRQ's if you're not using them.
    4. Raid driver problem. Check the version of the Intel Raid Bios and make sure the drivers used are same or newer. They might have used an old version on the floppy that came with motherboard.
    It sounds like you know what you're doing but try scrolling through the Intel portion of the Raid Guide and see if you missed anything. If you're going to try configuring the Raid again, why not enable Raid in the Bios and install Raid drivers during the Windows install but only on 1 drive. Run with 1 drive for a while and see if the corruption occurs. If not, migrate to Raid0 with the second drive as described in the Raid guide. Sometimes just installing something in a different way will solve an unidentified problem.
    Sorry I can't come up with something more definite. I just haven't experienced anything like the problem you're having. You're not booting 2 different OS's from that drive are you?

  • 875p: temperature and fan speed

    I've had my 875p running only for two days so far and I'm pretty happy about it. After reading some posts here I decided to brave a bios upgrade to 1.4 and indeed that did lower my cpu temperature. At this moment it's about 41C. Prior to the update it was several, maybe 10 degrees higher sometimes (also did the Arctic Silver thing as well after scraping off the original goo).
    But I'm curious about the cpu fan. CoreCenter beeped at me furiously until I told it not to worry. The fan sometimes slows down well below 1000rpm and sometimes stops completely for a while. I'm guessing this is normal and since my cpu temperature looks ok I'm not too worried. Perhaps though someone can feedback to me that this is normal behavior for this motherboard.
    System fan speed shows as zero all the time. I wanted to plug the Enermax 3-pin fan wire into the mb but that would have given me nowhere to plug the rear case fan. So the rear fan is definitely spinning and plugged into SFAN1. The Enermax fan goes to a converter wire to a regular power cables. So why no feedback to CoreCenter?

    Yeah the Cpufan speed is somewhat wrong.
    I hade a TMD-fan as cpufan.
    And about every 3d second the cpufan speed goes to 0.
    Else it just reads everything from 1100 to 9090.
    Witch is wrong.
    But as i can see that it spinns the wrong reads in not the problem.
    The 0 reads every 3d second is, because of Corecenter.
    I hear the alarm for nocpufan every now and then.
    Even if i set the cpufanwarningspeed in corecenter to 0rpm, the program still jumps up and warns me if the fanheader missreads the fan-rpm to 0.

    i would not even try to power up the sys untill the psu is in place,if the cpu failed and needs a warranty replacement i dont think you will get any fuss out of intel,BUT you may have other problems looming that may appear at some time or another,lack of AMPERAGE {not voltage} can have a very  NEGATIVE affect on the sys as a whole,if it is a mobo failure you should be ok with that also,it just takes a long time during a RMA process since it usually takes 4 to 6 weeks to complete each,mark it up to a learning experence,the PSU {imo} IS the most important piece of hardware that you or anyone will purchase for a computer !

    ,i donot use it but many here do and find it very usefull. also look here  https://forum-en.msi.com/index.php?topic=34535.0;all
    also the battery can have a bad contact which can cause a no post,also the psu connector pins can become dislodged and push back and cause arching {because of current jumping} that can be harmfull to the pins and sockets.
    hope this helps!

  • Overclocking an MSI 875P Neo-LSR Bios 2.2

    Yesterday i tried to use CoreCenter and went to 215MHz (3.6 Ghz i think) with no hitch.
    Now my question is with this configuration what can i reach and what to use (CoreCenter or Bios) ?
    And which OC for the memory ??

    I think use bios is better because of more flexibility. You can go up to about 3.5GHz.

  • HELP ! 875P Neo JAUD1 for front Audio with Thermaltake XASER III

    I am trying to connect my new Thermalake case V2000A (the aluminium tower with 7 FANs) front (well top) audio connetors to JAUD1 on the motherboard (875P Neo FiS2R)
    The XASER III wires say :
    EAR L jumped with EAR L (Case manual says connect two "EAR L" to "BLINE_OUT_L" and "Line out_L" on motherboard)
    EAR R jumped with EAR R (Case manual says connect two "EAR R" to "BLINE_OUT_R" and "Line out_R" on motherboard)
    GND (Case manual says connect to "GROUND" or "AGND" on motherboard)
    MIC IN (Case manual says connect to "MIC INPUT" or "MIC 2" on motherboard)
    MIC VCC (Case manual says connect to "MIC POWER" or "MICPWR" on motherboard)
    The JAUD1 connector on the motherboard comes with TWO green jumpers out of factory. One jumper shorting pins 9 & 10 and the other jumper shorting pins 5 & 6.
    Page 2-25 of the motherboard manual says:
    Pin 1 - AUD_MIC Front Panel Microphone input signal
    Pin 2 - AUD_GND Ground used by analog Audio Circuits
    Pin 3 - AUD_MIC_BIAS Microphone Power
    Pin 4 - AUD_VCC Filtered +5V used by analog audio circuits
    Pin 5 - AUD_FPOUT_R Right Channel audio signal to front panel
    Pin 6 - AUD_RET_R Right channel audio signal return from front panel
    pin 7 - HP_ON Reserved for future use to control headphone amplifier
    pin 8 - KEY No pin
    pin 9 - AUD_FPOUT_L Left channel audio signal to front panel
    pin 10 - AUD_RET_L Left channel audio signal return from front panel
    Now, I assume :
    Case "MIC VCC" should go on Pin 3 (or maybe Pin 4 ?)
    Case "MIC IN"    should go on Pin 1
    Case "GND"       should go on Pin 2
    Case "EAR R"     should go on Pins 5 & 6 (I need to REMOVE the green jumper ?)
    Case "EAR L"      should go on Pins 9 & 10 (I need to REMOVE the green jumper ?)
    Thanks for all help !

    I have yet to put the PCI cards inside but so far I was able to reach that end corner of the motherboard with the case top sound cables.
    As soon as I get answers on this Forum to my queries from more knowledged people about the right cabling (this and other posts on firewire and something else), I will then be able to finish all connections and finally place also the PCI cards and the video card and will let you know if it all went ok without the sound case cable stretching too much.
    Thanks.
