Northbridge fan

Is it possible to get the original northbridge fan that comes with the board for my KT4 Ultra from MSI?

I use the blue orb and I stuck it on with stickem tape,"thats not the stickem with a gun". seem to work great, you could put a fan on the heat sink, you will need to make the holes bigger in the fan and put bigger screws in i guess but the blue orb does it for me. basically a cooler is a cooler but i choose the vga for it is ment for high heat.

Can anyone recommend me a Northbridge fan replacement?

I have a MSI K8N Neo4-F nForce4 and recently i have been experiencing random crashes and lock ups which i think are due to the northbridge fan failing (it was making horrible noises).
I tried to replace this with the Asaka heatsink/fan combination thing but it didn't fit under the graphics card as there is only about 1.5cm vertical space available. Can anyone recommend a replacement suitable for this motherboard? Preferably a cheap one. =)
Also -i don't know much about chipset- is it safe to run the computer without a northbridge fan installed assuming i don't do anything intensive like games or whatever?
Thanks in advance.

I was sniffing around some other forums,(as you do), when I came across this post. It sounds intresting, and may be worth giving it a try.

"Repair your noisy cpu and system fans
This is a fix that will last for a long, long time.
Buy some graphite powder and some oil at an auto or hardware store. They come in different packages. For oil, the best is the pen-type as they are easy to handle and only give a small amount at a time. Just about any oil in a pen format will work fine. The graphite powder comes in small plastic tubes. But make sure you get graphite powder, not graphite oil, its too thin for this job! So you need graphite powder in a small tube and oil in a round "pen" that can be squeezed out and placed just where you need it. Also, when the oil is used up in the "pen" you can open it and add your own oil.
First, clean the fan blades off real well. If you have a heatsink with the fan then clean the heatsink off as well. You can even use a bit of your oil and some q-tips for cleaning if needed. Then, take the small circle, it usually has a name on it, but its in the middle of the fan. Peel one edge up carefully and put a very small amount of oil in where you lifted the label up. Now add some graphite powder in the same place where you put the oil, add as much or a bit more of the graphite powder than the oil. Clean off excess oil and graphite and push the label back where it was. You may need a very small amount of duct tape to hold the label in position and to prevent leakage. This is important if the fan is going to "sit up" as opposed to lying flat.
Now put the fan back where you want it and when it starts spinning it may be noisy for a few seconds until the graphite\oil works its way in. Then it will stop and it will stay stopped for many years and you may very well not need to buy a new fan after all!
I experimented a lot with this and this is the very best way to quiet all those fans and have them work well. I have always been a big fan of those removable ide hard drive trays that you can buy. But the fans are the pits, they get noisy real fast. So i had to find a way to fix them as they are very expensive and hard to replace. Now i don't have to. Combo of oil and graphite is the very best, by far. One caution, graphite stains worse than
oil, so be careful! I'm talking about staining your clothes and hands.
You can use this system with all CPU fans, video card fans, system fans, and even fans inside power supplies. But one word of caution, its easy to open a power supply and take out the fan, but do be careful as there are voltages there can can hurt you badly. If you don't know what you are doing then wear rubber gloves to get the fan out and to put the fan back in after the
repair!
Trust me, this will work. If the fan spins my method will work for years and I have even fixed fans that were stuck and wouldn't spin! This is better done with the fan on the table but in those cases where you cant or don't want
to take the fan out of the system, that's where the "pen" with the needle comes in again, but i still find a way to get some graphite in as well, graphite is what makes the oil last a long time! And graphite is also an oil, but you need both together for maximum effectiveness. Oil by itself will only last a few weeks or so and then evaporate, and the fan will get noisy again. Its the graphite powder that does the long term job. The oil really only helps to spread the graphite powder around really well so the graphite can do the job!
Hope you do as well as i have with this info!"
End Quote.
Edit - Additional Info
The type of northbridge fan used on some MSI boards, eg K8N Platinum & Diamond etc, require that you remove the fan from the board first (you will have to remove the motherboard to do this). This is because the top of the shroud is attached from the bottom by two tiny Phillips type screws. Once you have removed the shroud, very gently prise off the fan from the motor assembly. There is no need to try and remove the three other tiny screws that secure the fan motor in place to the bottom half of the shroud. Once removed, you will see that under the fan is a small plastic pin that holds the sleeve bearing in place.

Question About Northbridge fan

First, my system specs:
Intel Pentium 4 Prescott 2.8GHz HTT w/ 800MHz FSB
Thermaltake Spark 7+ Xaser Edition A1715 CPU Cooler
MSI 865PE Neo2-PFISR motherboard (BIOS ver. 3.8)
2x512MB Kingston PC3200 DDR SDRAM @ 400MHz
Maxtor 6Y120M0 120GB HDD 7200RPM SATA150 8MB cache
Built-by-ATI Radeon 9800 Pro @ XT 128MB DDR 256-bit @ 415/744 (Catalyst 4.12)
Arctic Cooling VGA Silencer Revision 3
Creative SoundBlaster Audigy2 ZS Platinum
Sony DDU1612 40x/16x DVD-ROM
Sony CRX230ED 52x/32x CD-RW
Enermax Noisetaker EG475P 470W PSU(+3.3V = 34A, +5V = 40A, +12V = 33A)
Windows XP Pro SP2
Even though on MSI's website the picture for the PFISR doesn't have a northbridge fan, mine does. So, is there a reason why this thing is so bloody loud? It sounds like a piece of plastic is just barely sticking up into the fans, creating a rattling sound. If I turn my CPU fan speed down to a moderate speed, the NB fan is the loudest thing in my case, and I have five 80mm case fans and two PSU fans going full speed.
Does my motherboard have fan control for this fan? Is it possible to turn the speed down some? What if it I just remove the damned thing altogether? I don't really see the point of having the fan there anyway, since both it and the heatsink are so small that they can't really be moving that much heat. How hot does the northbridge usually get? Is it possible to overclock the northbridge and see any performance gain?

A shortcut will be created in that folder, right-click on the shortcut and choose cut, navigate to the startup folder, usually C:\Documents and Settings\All Users\Start Menu\Programs\Startup, and paste the shortcut into that folder. If you have a shortcut already on the desktop you could right click on that, choose copy and paste that shortcut into the startup folder. Speedfan will now startup with windows.
Thanks, that worked perfectly.
And I configured Speedfan to only run the NB fan at 75%, and it is now much quieter.

P4N Diamond - Northbridge Fan

Since getting my P4N board (September 2005), the Northbridge Fan has been really noisy. Lately, it has stopped turning at certain times - either while the PC is in use (causing it to shut down) or on startup.
When the problem happens on startup, I have to give it a little push to get started.
What I want to know is - can I replace the fan? If so, how do I get it off.
Also, please could someone recommend a fan that will provide the same level of cooling, but also be quiter. I would also like to know the spec of the fan - can't find details anywhere.
I would have liked to put this post on the Diamond VIP Forum, but can't find a link to the URL for this??
Many thanks.

I have temporarily put this fan on (keeping the msi heatsink).
http://www.akasa.com.tw/akasa_english/spec_page/fans/spec_dfs401012m.htm
It is spinning at up to 6250rpm, but is slightly quieter than the original msi fan.
Potential problems/issues...
- it is supposed to have a speed of 5400rpm, so I wondering if it being reported at up to 6250rpm is an issue?
- the northbridge is now 47C rather than 45C at idle
- the new fan has 7 blades, the original had 9, so it's looking like the original fan was more efficient at cooling the northbridge chip
I also have the zalman heatsink and will likely replace the msi heatsink with this and use no fan, but wanted to check whether anyone has done this successfully, while keeping a standard intel cpu fan in place.
While I have a couple of minor reservations about the new fan, it does work, whereas the msi fan was pretty much knackered and completely unreliable. I could just replace the msi fan with another msi fan but I would expect that eventually the replacement msi fan would go the same way as the old one?
Any and all advice or suggestions would be much appreciated. Many thanks, Nick

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 ?

KT600 Northbridge Fan

is it possible to purcahse one of the Northbridge fans (made by MSI) from them, as when I bought the mobo it was pictured with the fan, but it did not ship with it, which was slightly dissapointing.
I am using the KT600 FISR
--

My KT6 FISR came without the DLEDs, so I just wacked in the card that came with my Dad's Intel MSI motherboard. That worked fine, I guess the problem is buying it, not actually getting it to work or anything like that.
What department should I contact at MSI?
Would I be paying more than £10?

Northbridge fan speed

I just bought a MSI K8N Neo3 nForce 4 mainboard. I have updated the bios to the latest version. Activated cool and quiet, and the smart cpu fan control. When I enter the bios the northbridge fan works at around 7500 rpm! And make so much noise. Can this be correct. Can I somehowe slow it down? It also seem like the cpu fan goes to fast, over 3000, the temperature on the cpu is 30 degrees. It's a AMD semperon 2800+. Somebody help me?

It's been posted many times already.
You could get the zalman fanmate2 to lower the rpm of the NB fan.
It will go as low as 2800rpm,but keeping it around 5400rpm should do the job just fine.
I run it around 5000rpm(jumps up and down between 5000 and 5400) and also I've ordered a replacement fan from msi in the netherlands,it's on the way free of charge.
I did this because now I've greased the standard fan several times already because of the grinding noise it sometimes produces,even at 5400rpm.
Also speed seems to drop down occasionally,so for now I'm fine,but the replacement fan will come in handy since this is leading to a dead end.
This new fan seems to run at approx 5400rpm btw.

This seems in order.If you can't lower the cpu fan speed you might need a bios update or cpu driver update.
Or your cpu isn't supported by the cool&quiet chip.

Northbridge Fan for Neo2-PFS

I just built my first PC with the neo2-pfs and i found out that the northbridge gets too hot. I can feel the heat through my side case fan.
Does anyone else have this motherboard? Can I install a northbridge fan on it? What fan would you recommend?
MSI neo2-pfs
Intel p4 800fsb (no OC)
Samsung 160GB
CD-RW
420 Watts
Raidmax case

Yes I have the i865 (P) Series Board, But What do you Mean that you can "Feel" it through the Side of your Case?? How Much do you have your FSB overclocked? Are you Running your Memory Synchronous (1:1 Ratio) with your CPU? ... And yes, you CAN Install a NB Fan, but Believe me if it is not a "Stock" Componant, then I assure you it is NOT Needed, as the Max. Temp. Spec. Limit of the i865's NB is 100C ..Now I know that you are No where Near that with your Board .....But If it Will Make you feel better then there are Many Choices for NB Fans out there...............Sean REILLY875

Replacing my Northbridge Fan

My Northbridge fan has stopped and I need to replace it. How do I get the old one out? From reading the forum it looks like this is a common problem and many have probably already done the job. I am hoping I don't have to pull the MB, but I think I might have to. Any precautions to watch out for. Thanks for all replays.

As Henry has already said, you will have to remove the board from the case to do the job. Have a read of this thread :- https://forum-en.msi.com/index.php?topic=98720.0 It will give you an idea of alternative coolers available to you.
Also you can download a helpful video that shows you how to do the job from here :- http://www.angrygames.com/vids/street_tuts/evercool2.zip
The only other advice I have for you is to make sure that you've grounded yourself before starting any work, and put the motherboard on a non conductive surface whilst doing the work, so that no damage from static occurs. Also run the pc for a couple of minutes before starting the work so that the chip heats up a bit and softens the old paste, that will make it easier to remove the old cooler without damaging the chip.
Good luck,and let us know which cooler you go for and how you got on.

Northbridge fan dead and lockups

I have the MS-7125 motherboard and recently have been getting hard lockups: the mouse and keyboard freeze and I can't even ping the box. The only solution is a hard reboot. These lockups now occur at least once a day.
The BIOS tells me that the Northbridge fan has 0 RPM and, sure enough, it's not moving. Could a dead Northbridge fan cause these lockups? If so, where can I get another one? (It appears that they're replaceable.)
Thanks for any hints or pointers.

Northbridge fan has been dead in my board for months with no problems but that doesn't mean to say it's not causing your problems?
You're right. I successfully (and easily) installed the Vantec CCB-A1C Northbridge fan and it appears to be spinning but when I booted Gentoo Linux AMD64 it froze within minutes. It's a dual boot machine and I'm now running Windows XP continuously. If it runs without freezing for three days or so I assume that the hardware is fine and that the problem must be a Linux driver that causes the lockup.
Am I on the right debugging track or do I have other options?
Thanks.

I Need clean Northbridge fan/cooler

hello everyone!!..and sorry my english!
I have a K8N Neo4 Platinum ..How Can remove the NORTHBRIDGE fan/cooler without removing the motherboard?
i NEED clean it ... Can i do?
Thank you

Hello!
Best is to use high pressure air. Hold the fan still with a pencil while blowing.
Or use some cotton on a very small stick. Hold the fan still. Clean on both sides of the fan.
If you need to clean the NB fan, I think you have more cleaning to do. Better to take motherboard out.
Be careful!

Northbridge Fan Problem

I have an 865PE NEO2-LS. It's about 6 months old. The northbridge fan just started making a strange noise. When looking at it running, it seems to suddenly stop, then immediately spool back up again only to stop again. The whole cycle takes a little more than a second. It produces a pretty loud intermittent buzzing sound, much louder than it was before it had this problem. How can I fix this? Thanks for your help.

This Correct, as I have Done Experiments with my Infered Heat Gun, and there is a 1C Delta Between having the NB Fan On and Running and with it Off........But if you Like the Lights, Try compressed Air, and some Oil (A Tiny Amount) if not E-Mail MSI for a Replacement.................Sean

Hate that whiny Northbridge fan

865 PE Neo2 LS P4 3.0 H/T.
That Northbridge fan is irritating. How important is it? I mean, there's a good size heatsink there. Do you think I could just unplug it? I looked at Zalman fanless heatsink but my board doesn't have the needed holes. Also, I'm getting the big Zalamn CPU heatsink/fan (120mm) which might help cool it.
Thanks.

If the fan your talking about is the one with Red Green and Blue LED's in it, rip the sucker out.
I've ripped it out of a few PCs, they are house and make a hell of a noise.
Just make sure the case has good airflow over that heatsink, or she may get a little hot.
I think its there for looks more than anything.
Otherwise just find a simalar fan to replace it with.
If it is under warranty, take it to where you brought it and insist that THEY replace the fan for you, under warranty.

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
rockos

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