P67A-G45 (B3) fan speed keep dropping to 0 rpm

I just got this motherboard (P67A-G45 (B3)) for a month. Just only today, I notice the CPU fan speed being detect keep on going to 0 rpm every 10-15 secs. It goes to 1800 rpm then after like 10 secs, you can it become 0 just for a second. Then it goes back to 1800 rpm.
When I turn view this under control center II in windows 7, it also shows this symptom and alarm get triggered.
I did not do any over clocking. I am using Cooler Master Hyper N520 heatsink. The fan for this heatsink only have 3 pin which I doubt is the reason for the board to detect 0 rpm. Anyone having similar problem with this motherboard or HSF?

My parts for 2 units of 3-pin fan cable arrived. After some modding, I connected it to replace the existing 3-pin Y-cable. Partially works. When I check in the BIOS level, I can see the speed drop occasionally to around 500rpm. However, when I boot up to windows and using speedfan, below is what I get.
Still getting speed drop to around 500rpm but it happen less frequent and at least not 0 rpm. I am okay with this. As I don't have another motherboard to test. Plus I really do not want to take out the HSF again as it is a lot of work. Need to take out the whole motherboard for that.
edit:
I switch between fan1 and fan2. Take note fan2 is sysfan1 on the motherboard. I plug the HSF cable into fan2 and for fan1 I plug the PSU fan. So this time I see fan2 speed drop to 500rpm every 8 minutes.
So conclusion, problem is with the HSF. Cable? Or the Fans? And why does changing the cable fixes the problem "partially"?

Z77A-G45- CPU fan speed problem

Hi all, new to this forum and MSI Motherboards.
i have a problem with my CPU fan speed when i plug any fan and water cooler fan into the CPU 4pin they all run at 2000+ rpm, but when i use the fan 1 or fan 2 --4 pin it runs at a slower speed of 1400rpm, am i missing something in bios, i have 2.5 version of bios, would be greatfull for any help....

Should be able to adjust in the section below or with control center.

Router off for 2 weeks now speed keeps dropping of...

Having been on holiday, I turned my router off for the period I was away from home. Since I have got back I have been randomly experiencing speed dropping off to point where the connection is useless. I can't run the speedtester because it's so slow. The connection itself is stable i.e. my router is staying connected for long periods.
If I restart my router, when I reconnect I am synching at around 12mbps, and for long periods (sometimes 18 hours including overnight) the connection remains fast. Then, at various points during the day (2 or 3 times), the speed drops off and won't come back unless I restart the router. This seems to happen when the connection is in a period of inactvitiy eg. browsers left open but no one actively using computers/downloading on the connection. This only seems to happen only during the day. Overnight, the connection speed remains high as I have been checking every morning.
I'm slowly beginning to get fed up with having to restart the router, not to mention the fact that the exchange may perceive the connection drops as line instability rather than manual restarts and drop my synch rate accordingly. I have had to restart the router 2 or 3 times per day for the last 3 days.
Having checked the quietline there appears to be no interference on the line and all of my connections appear good - as indicated earlier, in the main the connection is stable and fast.
Can anyone indicate as to whether the fact I have had my router off for 2 weeks affected my IP profile? and this will resolve itself over time or should I just get on to tech support? The fact that this has started happening since I have been away just seems too much of a coincidence.
Any help/opinion is appreciated.
Regards
Alex
Solved!
Go to Solution.

Thanks imjolly....
I'll definitely give it a try - hopefully things will start to bed down soon.
The problem with running the speedtester when it slows down is that it's so slow I simply can't run the speedtester - I can't access anything, so I have no way of measuring exactly how slow it's gone.
The hardware upgrade email I received on 7th Jul this year states
"Your line needs time to settle down
For the next ten days or so, your broadband might slow down or even stop now and again. That’s normal and your speed will soon settle down. You can help it along by leaving your BT Home Hub or router on all the time and using your broadband as much as you can for this period. "
Thats all fair enough, but nowhere does it give an indication of what is a reasonable period of time for it to "stop". It's almost as if the bb connection stops, as indicated above, but the equipment at the other end is unable to restart the connection and as a consequence I have to reboot my router to force the issue. As detailed above the process is also helped by "using your broadband connection as much as possible", but if it stops working as I've seen - I can't use it without restarting the router - so that puts me in a bit of a "chicken and egg situation".
Hopefully I'll be able to get away with leaving it alone for a few days.
Thanks again for your input.

MSI Dual Core Centre 2.0.1.0 (Fan Speed ALARM)

Spec:
MSI P965 Neo F v2.0
Intel E6600 Core 2 Duo
XFX-Nvidia 7800gt 256
4 GB 800Mhz Ram
Hi guys,
Anyone here know why the following would happen:
I use the MSI Dual Core Centre 2.0.1.0 for Windows XP... every so once in a while, the fan speed would drop to 0-RPM, and
a very irratating alarm would go off. This started to worry me, and I opened my side panel to look at the CPU Fan when the alarm goes off.
the Fan is turning at high velocity, but the alarm still goes off. Is there something wrong with this software ? or am I doing something wrong.
One minute it reports 2005-RPM, then it just shows 0-RPM, and the alarm goes off. My machine is about 2 months old.
Should I be making changes in the BIOS on the Mobo, to enable support for Dual Core Centre???
Please help...very worried...
By the way "Speed Fan" reports no such alarms or CPU fan speed issues...
What is going on ?

Not sure if this may work bc you reported fanspeed reaching zero.
On my system with 975XPUE, Arctic Cooling Freezer 7 always runs below 1K rpm. So I have to use a user profile with Fan Min set about 833 rpm to avoid the annoying alarm.
If you don't find any solution to the reported fanspeed reaching zero, you might be able to at least disable the alarm by setting Fan Min in DCC to 0 rpm. That or uninstall DCC as suggested by most forum users.

Unable to adjust fan speeds after OS X reinstall

Hi all,
I recently had a problem with Mac OS X on my MacBook Pro that eventually led to me reinstalling the OS from scratch. I erased the drive completely and did a clean reinstall using the Mac OS X 10.4.10 discs that came with the MacBook Pro.
Prior to reinstalling the OS, I was able to use the smcFanControl utility to adjust the fan speeds in my MBP as I saw fit. This was a great solution to keep a good balance between noise and temperature. I kept them running at 6000 RPM most of the time because I work on the computer at my desk most of the time. However when I take it to school with me, 6000 RPM is too loud to use comfortably in my classes. I used to be able to lower my fan speed to 4500 RPM, but since reinstalling, running smcFanControl will lock my fan speeds at the max (6000 RPM) and not allow me to lower them. Attempting to enter values manually tells me that I am attempting to lower the fan speeds below the minimum allowed value, but the fans are supposed to be able to range between 2000 RPM and 6000 RPM.
I'm not sure why an OS reinstall would break settings like these, but it appears that it has. Does anyone have any idea how I can reset the range of fan speeds back to what they're supposed to be?
Thanks very much!

Thanks for the reply. Sorry it took so long for me to get back to you but I finally gave this a try and it did not work.
I am currently using the Fan Control application you linked to (as I have been even before I came here) but the variables in that program don't allow me great enough control over the fan speeds. It is temperature-based, which I like, but the minimum and maximum values generally keep the fan speeds too low and the machine still too hot. I am using it temporarily but I much prefer smcFanControl because it allows me to set the fan speeds directly.

CPU Fan Speed always LOW? -- K8N NEO4 Platinum SLI

I'm wondering if anyone can help me out. My CPU fan speed is consistently around 850 RPM, both at idle and under full load. This is shown in the BIOS, with Corecenter, Everest, and Speedfan. I have Cool n Quiet disabled in the BIOS, CPU Fan Target in BIOS set to 40 deg (have had it at 60 as well), and Windows Power Scheme set to Minimal Power Management. I've even tried enabling Cool n Quiet to see if it actually did anything...but fan speed is still the same.
It seems everyone else has CPU fan speeds in the thousands rpms. Mine never changes, is always around 850.
My CPU temps vary between 37C idle and 48 load when my ambient room temps are around 75 deg.
What's up with my CPU fan?
EDIT: Speedfan doesn't seem to work for adjusting anything. It only shows my CPU (fan2) and NB (fan3) fan speed, but adjusting the percentages has no effect.

Try setting cpu fan speed to max to access this open corecentre & click on logo.
should give:-
Select user mode & set Fan to max. This info is held in the corecentre chip & is the only way to access it .
Only keep corecentre installed for this function
hope this helps.

Thinkpad T430u low fan speed

Hello!
When I am playing on thinkpad t430u CPU/GPU becomes very hot (95-100C), but fan speed is only 3000-3500 RPM. Using "tpfancontrol" I achieved almost 5000 RPM at manual mode and temperatures decreases to 70-75C.
Why fan is so slow at auto mode?
I updated BIOS, but it does not help. Moreover in BIOS there is no fan settings (quiet/performance) as on my old PC.
OS: Windows 8, Nvidia GPU, latest drivers.
Thanks!

Hi!
During normal working (word, firefox etc..) temp is around 60-75° with the fan always running at 3800rpm.
While I was doing a map upgrade on my garmin navigation system the notebook crashed many times in a row and I couldn't figure out why.
After some investigation I found out that it was the system overheating protection shutting it down.
I checked this by putting stress on the cpu with prim95 and there the temp goes up as I described in the previous post - just faster than weith the map upgrade. Ambient was 23-24° C.
What just made me wonder is why the hell doesn't the fan speed go up like it once used to do!?
I would expect the fan speed rising at around 75° or so but instead it started at 95° C which way too late!
This is my 3rd Thinkpad and I never experienced this behavior - however I am not sure when it started.

Qosmio F50-126 - Fan Speed never htting maximum

Hey
This issue been bothering me for a long time but was too lazy to post on it. When I boot up my notebook, you can hear the fan speed hitting its maximum RPM. But during gaming when the laptop is about to reach its maximum temperature to restart, the fan speed never hits its maxium RPM. It always seems to be about 50 percent when it about to hit the overheat threshold.
Can you tell me how to fix this issue so the notebook does us its fan maximum RPM during gaming or some other cpu/gpu intensive process?
I have all the lastest BIOS and drivers installed to date.

Hi
The fan speed is controlled by fan table which is stored in the BIOS.
Usually the fan speed would be set to a higher level only if an certain temperature level has been reached.
Furthermore the notebook would shut down automatically if the temperature level would be too high
If the unit runs stable, I would not be worried about the fan performance.

Normal woring temperature and fan speed?

Hi,
I have installed vista x64 bit on macbook pro and have some questinos.
FIrst, can someone help mi to find keyboard shortcuts for turning on/off wireless network and bluetooth... if is this possible.
Second, I have installed "input remaper" that allow me to reconfigure some keyboard shortcuts, and it automatic control fans and monitor CPU tempereature. It is between 60-70c and fan speed is set on 2000 rpm minimum... Is it this ok, mean this temperature because machine is sometimes really hot....
Regards,
BA

I too have been wondering the same things. My temps are very high as well 68-69C for the GPU and 65-67C for the CPU cores when under Vista. I do not believe that Vista has any method to control the fans at all for the new unibody macbook and macbook pro models, at least that is the conclusion that I have been coming to myself. I have tried speedfan, riva tuner, coretemp, input remaper, and ati tool, all to no avail. Nothing knows how to properly access and control the fans for the laptop under Vista, and on top of that, the 9600 GPU is the one in use when under Vista, which means even more heat at idle. This really needs to get fixed with an update of bootcamp or a full driver release for vista.

Are my fan speed/temperature normal? Please answer quickly, warranty is expiring!

I have an MSI GF4 TI4200-8X.
I had some problems with my computer, when playing certaing games it freezes after a while, with reboot needed. I think I got down to my graphics card overheating. While using 3D turbo experience, I found out my fan speed was about 2700-2900 RPM (I think it is the minimum!!!) and my temperatures where around 52-55 idle. Today I noticed my fan slowed down, and it wasn't even showing fan activity, I tried pushing the fan a bit and it stopped completely. It has restarted again, with fan speed around 1700, after leaving the computer running for a while it got back to 2700 with slight variations to 2600 +-. The temperature went up to 58º!!! But I think it's "stable" now at 53º. What I'd like to know is if these values are normal for my graphics card. I couldn't find much information about this in this forum, one or two messages mencioned fan speeds around 3900-4000. As my board is still covered by warranty I'd like to know if I have reasons to send it back. So.......do I?

Quote
What does usually happen there when you have a graphics card under warranty, and it has a problem, you send it back right? And in the meanwhile? They give you a replacement until the other one comes back from repair (or even exchanged by a new one) ? I don't really know how these things work in these situations..
Like I said you will be without a card for a while. It could take weeks or posibly a month or more. It is not like a car. Contact the reseller to see if you still have a return possibilty with them, otherwise, you have to go to MSI for an RMA request.
An aftermarket cooler can be found at an online retailer or even at a Consumer Electronics SuperStore but I do not know what you have in your country. Thermaltake http://www.thermaltake.com/ has good products, perhaps you have a reseller in your area that sell their products.

CPU fan speed on P45 Neo3FR

I just installed Coolermaster Gemini iis cpu cooler on my system. From the HW monitor, I found that the max fan speed was only 1867 rpm. A similar reading was found on the reading of DualCorecenter utility. I have put the CPU fan speed in the bios to maximum but no change. The support center of coolermaster has confirm that the fan is able to run up to 2000 rpm.
Does anyone have a suggestion?
My system is
mb: P45 Neo3FR pcb 1.0
bios 1.8
CPU : E8200
PSU : Antec pure power 430

I tried the options in the smartfan, but no response. The fan speed did not change. Actually, my problem was the cpu temperature is about 1-2 degrees higher than the stock cooling. So, I took of the fan, cleaned both CPU and cooler, applied the correct amount of thermal paste following your suggestion. Now, the CPU temperature is about 40 to 41 C during idle compare to 43 to 44 using stock cooler. The fan speed has increased to 1910 rpm.
I just wonder that the fan speed may not properly regulated by the bios. Do you think it is necessary to tell MSI support?

Minimum fan speed on N650Ti PE 1GD5/OC

Hi all,
is there any way to lower fan speed below 30% (around 1100 RPM) on N650Ti PE 1GD5/OC?
MSI Afterburner doesn't allow to setup fan speed under 30% which is IMHO really to high for idle state (GPU temperature is around 28C using that minimum fan speed).
Thanks in advance!

There is no way to go below 30% by software. That would require modding the vbios.

USB/FireWire usage increases CPU temp and fan speed

Hi,
I'm curious, does the usage of USB and FireWire ports increase CPU temperature and fan speed...?
I have an M-Audio Fast Track USB interface plugged in and whenever I play any songs from iTunes using that interface as an output, my CPU temp increased and fan speed jumped from 2000 to 3300 rpm. And on separate occasion, an 8GB of file transfer from an external FireWire-based HDD had both fans speed up to 4,400 rpm.
Is this normal...? All these were done with an external display plugged onto the MBP with "clamshell" mode.

USB operations involves quite a bit of CPU action, Elphidieus.
Firewire places less demand on the CPU but, in a situation like the one you describe can involve both increases in power usage and in HD temperatures.
The fan speeds on Macs are not simply responsive to CPU usage. Both HD temps and power usage can also play a part in the equation that ultimately produces the fan speed. As HDs have much lower heat tolerance than CPUs you will find that it is quite common to see the fans ramp up when doing a large file transfer over FW (or USB, for that matter) , especially if the internal HD temp gets to over about 50-55º Celsius.
Cheers

P67A-G45 Fan Control Problem After BIOS Update

My old BIOS version was 1.8. I could control my fans in BIOS(50-75-100% RPM). Also SpeedFan tool was working perfectly, I could change fan speeds freely.
I just installed MSI Live Update and tool updated my BIOS version to 1.E(CPU-Z says v1.14) without any problem. But when I entered BIOS/Hardware Monitor I saw that fan control is disabled. Both sys fan 1 and sys fan 2 are stuck in %65. SpeedFan doesn't working too.
CPU Smart Fan is okay, works fine but system fans are uncontrollable now.
My Hardware;
i5 2500k
MSI P67A-G45
G-Skill 1333MHz 2x2GB DDR3
Samsung 502HJ

Sapphire Pure 625W

Flash back to the BIOS that worked for you and report your findings to MSI technical. >>How to contact MSI.<<
Use the forum flasher in the future. Its safer. >>Use the MSI HQ Forum USB flasher<<

Connection keeps dropping and speed is getting slo...

Hi,
I have had infinity over a week now and after having a speed of 50M and a ping of 17 each day it has dropped and is now iro 34M and ping of 37. What is of more concern is my connection is keeps dropping. Has happened every day - DSL light going off on Infinity box and homehub. I did a speed check on BT wholesale and it seems my ip profile has been dropped down to 36M.
I am connecting wireless and have tried a different channels, tried using DNS even tried a new HH3 as I had a spare. But as yet no improvement. Anyone any ideas?
Thanks in advance.

You could have a fault, to check do the following.
1. Visit this link https://www.bt.com/consumerFaultTracking/secure/faults/tracking.do;jsessionid=2W59QB2TvDGLZST41KJS2T...
2. Make an account with your BT Account number, this is different to your forum account.
3. Once the account is created re-visit the link from instruction #1 and login
4. Now you want to click on "Check my line now"
5. You should see your telephone number in a box, make sure that box is ticked if not enter your number.
6. Click on "Check my line" once step 5 has been completed
7. Make sure the details are correct, select the most relavant problem to you. I find the most common is the top selection "I've removed all equipment...."
8. Finally, Click "Check my line" **MAKE SURE NO ONE IS USING THE PHONE** Once completed, post the results contact a mod if a fault is found.
