Connet cpu fan power to m/b or psu?

Hi,
finally my new computer case and thermaltake volcano 9 came this mornig.
I have a question about the power connection since I found a big connector (same as HDD's) which is used to connect to psu directily. I have K7N2G-ILSR M/B. should I plug my volcano 9 on the M/B or on the psu 12v connectoer?
Below is info about vocalno 9:
P/N A1365
Cooler Dimension 80x80x77.3 mm
Fan Dimension 80x80x25 mm
Rated Voltage 12VDC
Started Voltage 6VDC
Rated Current 0.20AMP ~ 0.70AMP
Power Input 2.40W ~ 8.40W
Max. Air Flow 20.55 CFM at 1300 rpm
75.7 CFM at 4800 rpm
Air Pressure 1.45mmH2O at 1300rpm
8.43mmH2O at 4800rpm
Noise 17 dB at 1300 rpm
48 dB at 4800 rpm
Bearing Type Two Ball Bearing
Life Time 50,000 hours
Connector 3 PIN
Tt Fan grille TR=0.38C/W

to the psu,if it does not have a seperate single wire speed sensor to plug in boards socket disable cpu fan detection in the bios,plug a case fan in there for first boot as it might not boot if it senses no cpu fan
big fan like that would pull to many watts and just burn out fan header

Yeah, I know that all that info probably isn't that necessary.
Problem: I have a Thermaltake cl-p0533 for my core i7 920. My fan runs 6000+ RPM all the time. I've tried using the overclock center, greenpower center, and the BIOS smart fan thing. In BIOS, I tried setting it to 25% idle and 50c target temp range. No dice. I've tried using speedfan and all that I got was the speed knocked down about 300-500rpm for a bit. My CPU idles at about 33c (according to speedfan and OC center). The CPU fan speed is supposed to be able to be controlled. The noise is really annoying. Any help would be most appreciated.

First, I meant 920 (I must be dyslexic or something)
Yes, the CPU fan is connected to the CPU fan power connector (according to the mobo manual). I've set SpeedFan for the same as I had my BIOS settings. I've since changed them to lower temps. I've tried SpeedFan with and without using the SmartFan feature in the BIOS enabled. My Two case fans are super quiet, so I don't use any regulation for them. So my SpeedFan settings look like this:
Speed 1 - minimum value = 25% maximum value = 100% auto variated
Temp 1 - Desired = 42c warning = 50c
Cores 0-7 = same as Temps 1 settings
I've also disabled the other temperatures for monitoring and fan control
As for the number of wires for the cooler fan, there are 4 going to the mobo.
I don't really know much about add-on fan controller parts. If that's the route I end up needing to go, any recommendations?

OK to permanetly remove CPU fans for ATI X1900 installation?

I've got a dual core G5. I just got the new ATI X1900 G5 edition. The installation instructions look like it wants me to permanently remove the cpu fans and plug the card's power cord into the cpu fans' power port.
Am I reading the instructions right? Is this a typical thing to do when getting a high-end graphics card? Is it safe to run the mac without the cpu fans?
Thanks!
Will

Ack!
Those CPU fans need to run, period. You have as close as I can give to a guarantee, let's say 99.99943%, that if that CPU fan does not run, that you will destroy the CPU core within a couple minutes. And that's a very, very expensive repair as warranty will not cover it.
Perhaps there is a "piggyback" on the Radeon's plug which allows you to plug the CPU power fan into it... effectively running 2 fans off the same plug.
Have a link to online docs for the X1900 G5 edition anywhere?

I can't imagine that that would be the case... Sure, you'd have great graphics, but you'd also have an overheating computer.
Both the 7800GT and FX4500 cards required a separate power cable as well, and neither of them needed the CPU fans (or any other fans) to be removed.
I don't have a picture of where the cable should plug in, but hopefully someone else will or you'll be able to find it on the motherboard. I'm also assuming that ATi expects you to you that connector.

Power cables are clogging my CPU fan!

Hey all.
I just upgraded my MEGA 865 from a GeForce4 MX to a GeForce 6600GT(mmmmm.....GT.....)
Anyway, all is going well so far except for 1 thing.
the trusty GF4MX was a small-ish card, and the thick wadge of power cables coming out of the PSU just came around the top of it. The GF6600 however is 'full-sized' There is no room alongside it for the 'snake', so i had to push all the cable under the PSU. This seemed fine, PC started up, Graphics card was working fine etc... Then i cranked up SpeedFan to check out my temps, and saw that Fan1 had 0 RPMs. Pulled the computer to bits again and tried to the cables around the CPU fan, but no luck.
Can anyone help me? I don't want a molten CPU!
(strangely enough, the CPU temp has actually only gone up by a few degrees compared to before, but i would still like to have the fan going).

what is fan 1?
are all the fans running that you can see of?
It isnt surprising the temp has increased, the newer video cards put out more heat, thus the internal temp of the box will be hotter.
also the bigger card will restrict air flow too....
Is your PC locking up? it will lock up way before anything melts.
I would use the system as is and if you have frezzing, blue screens of death, then investigate the fan problem furthur.

The drive part number is presently 665329-001 found HERE
However, I found that mydvddrives.com doesn't have a
However, as long as that site 'mydvddrives.com' is not 98% positive feedback. and doesn't have money refund guarantee. Also, since I don't find internal BlueRay drive in my own HP agent in Yemen. Thus, I had to look for 'TheHP-Compaq 665329-001 SATA Blu-ray BD-R/RE Drive, ' in ebay.com. But, zero results resulted in researching, although there are some other ones. I think that my search withTheHP-Compaq 665329-001 SATA Blu-ray BD-R/RE Drive is correct as long as that part number was sugggested by that HP agent.

However, I, myself, don't know if any BlueRay drive, other than that its part number is665329-001 can be working/compatible with my laptop or there is a specific part number of BlueRay must be purchased in order to work on my laptop well.
Thus, could you please let me know if any BlueRay other than that one TheHP-Compaq 665329-001 SATA Blu-ray BD-R/RE Drive can be compatible with my laptop or not??

Could anyone take some of his precious time out and reply to me?

975X Power Up CPU Fan issue

Hi,
Just got me a shiny new Power Up and an Intel Core Duo 6400. System is up and running and stable, but the CPU fan is constantly spinning at full tilt.
Dual Core Cell shows the CPU temp at 45C idle, which is at least 10 degrees over what I was expecting. More annoyingly is the fact the dual core center is not allowing me to control the fan speed. I can make chnages to the fan speed control, but the 'apply' button is greyed out. On the FSB side, the 'apply' button is not greyed out.
There must be something wrong somewhere? I'm using the latest offcial BIOS and Dual Core Center. Power supply is 600W.
I also tried using my Zalman 9500LED and again, that was permanently fixed at full fan speed. If anyone has any ideas, suggestions, please let me know. Even with the Zalman, full tilt is far too noisy in the quiet room where my PC is based.
Thanks,
czrsiNk

CPU fan at high speed due to power supply sensor

The CPU fan on my Imac runs at 3900 RPM. Apple hardware test provides an error code of 4 SNS/1/40000000:TpOP-131.000 which is the temperature sensor on the power supply. I opened the Imac and the single wire to the power supply is connected securely. At this point, the problem could be in the sensor wire ( which disappears into the wiring harness), the power supply sensor - which I assume is built into the power supply, or in the the logic board where the temperature information is processed. I have tried the SMC and PRAM resets with no results. The wiring harness is very difficult to replace, and the power supply is relatively expensive, so I would appreciate it if anyone who has solved this problem could tell me what the solution was. I would really like to repair the Imac and eliminate the loud fan noise.

Hi ee36,
Thanks for your response. I have performed the SMC reset you described many times with no positive results.
The apple repair manual for my Imac says to replace the wiring harness if you have this problem. A daunting procedure for me since you have to almost completely disassemble the Imac. It seems that if the sensor is disconnected (open circuit) the associated fan (CPU fan in this case) will always run at high speed. It seems to me that several failure modes would create this open circuit, and I was hoping that someone could identify how their Imac was fixed so I could hopefully determine the most likely effective repair. I have created an applescript program which I have set up to limit the cpu fan to 1500 RPM and limit the noise, but I would really like to have the security of knowing that the fan could respond to elevated temperatures if necessary. Thanks again.

CPU Fan Has Failed! PC will automatically power down

CPU Fan Has Failed! PC will automatically power down
HP Pavilion Slimline s3714uk Desktop PC, running windows 7.
I started to get CPU fan failure message and the PC would not boot, I opened up the case and the CPU fan seems to be connected and working.
Error message is “"ERROR: CPU Fan Has Failed! PC will automatically power down in a few seconds. Service the PC immediately to prevent damage to the PC."
I have found the following advice:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00013522&cc=uk&lc=en&dlc=en&product=3876701
However the bios version I have does not have the option to switch off the fan monitor. How can I fix this issue please: many thanks

Hi Susielee. what was the heat sink and cpu fan that the tech installed in your HP computer? I got a used HP s5120y computer from a longtime friend that is missing a processor fan but the heatsink is there.
update 2/14: never mind, my old friend forgot to give me the CPU fan, which he did a few days ago. I used a flashlight to check if the fan is working and it is but I'm still getting "CPU fan has failed" error everytime I power on the computer but the cpu fan spins okay at normal speed. replacing the cmos battery did nothing to solve the problem.
I will either replace the whole heatsink & fan before I will consider replacing the motherboard, which seem to have a least 1 ruptured capacitor on the board - that indicates some parts of the motherboard are starting to fail, like the fan sensors. The HP part number of the board printed on a sticker in the HP slimline S5120Y computer is "513426-001"
So in short replace the heatsink & fan assembly first. Then replace either the power supply and chassis fans. If those don't fix the CPU fan failed message at bootup, replace the whole motherboard.

PS and CPU fan comes on merely by plugging in AC power

I am repairing a friends Athlon xp machine and have tested everything with extras.
I put a new MSI KM4M-V board in. The pc runs xp fine, etc., etc., however, when shut down the pc, Windows shuts down, but the ps and cpu fan stays on. Indefinitely. I have to either flip the on/off switch on the back of the ps or pull the damn plug.
What gives?
When I plug the thing in cold, same thing; the fans come on and then I press the start button whenever I want and the system posts and boots normally.
A motherboard Short? I checked the switch and even pulled the connector; the fans still come on when I plug it in.
Any thoughts?
Thanks.
J Romulus

Yes, I've let it run for hours after Windows shuts off, it simply doesn't go off.
Simply plugging it in or flipping ps switch, the same thing; ps and cpu fans come on automatically.
I've read all the APIC threads; if I were strictly having problems shutting down, maybe it be that. But it is so strange that it does it from a cold start.
Got to be some kind of short, or else a bad board.

HP PRO 3400 Series desktop won't boot CPU fan starts and stops , no video, no beeps

I have the above computer with an i3-2125 CPU, Windows 7 Home Premium 64 bit, and a 300GB Seagate Hard drive. I've had it for about 2 years and been working fine. It started acting up about 2 months ago. It would lose the date and time. I checked the battery, and it was OK, so I kept using the computer. Then on 9/15/2014 it hung on "Starting Windows", I did the following:
1. Ran the built in HP diagnostic on hard drive and memory and they both passed.
2. Tried to go to last known good configuration and nothing happened.
3. Noticed the date and time were off, replaced the battery, nothing changed.
4. Tried another hard drive from another HP PRO 3400 Series and it would boot up but could not set date in bios.
5. Tried all kinds of things but could not set date in bios.
      a. Bios date read 48/00/0048 after removing and replacing battery.
      b, Tried to reset date to 9/16/2914 and it gets 56/00/0051
6. Then it wouldn't boot at all.   So now when you turn on the power, the CPU fan starts and runs for about 1 second, then shuts off for 4 seconds, then starts and runs for another 1 sec and it does this continuously. There is  no video and no beeps and no difference when all memory is removed.
7. I removed the power supply, and checked voltages. It appears to be OK.
8. I removed the motherboard, and inspected it- saw nothing obvious.
9. I connected the power supply to the motherboard with nothing else connected to the motherboard, and I get the same thing. CPU fan starts then stops continuously, no video no beeps.
10. I am thinking it is the Motherboard, but I sure could use some suggestions as to what to do next.
Thanks

[Solved] Asus L1366 mobo, cpu fan speed control

Hi, everyone,
I finally have this new core i7 system, to replace my old AMD athlonx2. I have one question about the CPU fan speed control.
I remember that in my old system, the cpu fan speed control works out of box, no configuration is needed.
But when I install arch 64 on this new i7 system, the cpu fan is running at its maximum speed constantly while the CPU temperature is modestly low. I know there is a wiki teaching how to do it.
However, I am just curious why it doens't work out of box any more? Does CPU fan control work for you guys out of box normally? especially the new Core i7 cpu users?
Please let me know, really appreciated it.
Thanks a lot.
Update: the issue is solved, see my last post, the solution is blacklisting: asus_atk0110, instead use w83667hg.
Cheers.

First off, it would be useful to know what the sensors-detect script actually reports.
Okay. How fan control works on Linux: First, navigate to /sys/class/hwmon
Each of these folders, i.e. hwmon0, stands for a sensors monitor / fan controller on your mainboard that may control one or several fans. Inside hwmonN, there should be a subfolder called device, which contains several interfaces if your BIOS allows software-side fan control. You can read them with cat and write to them with echo.
Examples:
pwm1_enable shows if OS-level fan control is enabled (1) or disabled and in BIOS control (0). Changing fan speed won't work if this is disabled. (i.e. cat /sys/class/hwmon0/device/pwm1_enable reports 0 -> disabled; you could enable it with echo 1 > /sys/class/hwmon0/device/pwm1_enable).
pwm1 allows to change fan speed. The values range from 0 (fan off) to 255 (full speed, 12V).
fan1_input shows the current RPM if a fan is connected. You can only read from this interface. Its useful to check all of these in the each of the hwmon folders to find out if there is actually a fan connected to the fan controller (they often have more ports than mainboard manufacturers use).
There might be a fan1_div, this is somehow related to how the kernel reads the RPM, I don't know how it works.
temp1_input interfaces can appeare too, if some of the chips have temperature sensors located somewhere. I *think* lm_sensors places the core temperatures it reads from CPU (the coretemp-isa-000X thingies) in one of the hwmon-folders too.
There might be interfaces for different fans in the same hwmon folder, i.e. pwm2_enable, pwm2, fan2_input, etc., all interfaces with the same index belong to the same physical fan connector, and all in the same hwmonN are managed by the same IC on your mainboard.
Warning: These interfaces, if they work, control the fans directly without any kind of security measure. If you shut some essential fan down, it will stay off until you reboot your CPU shuts down.
(If you see something likein0_alarm, in0_input, in0_max, etc. it's a voltage monitoring chip.)
If one of those interfaces can do something, OS-level fan control does work, if none of those folders contain a working pwm interface, fan control seems to be unavailable.
Sometimes there is an option in the BIOS to enable it, and for some BIOSs software-side fan control only works if dynamic fan control is disabled in the BIOS and fan speed is set to a static value - or vice versa.
I don't know what you are using to control fan speed, there are many applications that use these interfaces, i.e. GNOME or KDE power managers, so I'm not sure what is happening:
IF: Windows 7 enables OS-level fan control and sets it the RPM to those you observed and you have nothing that provides fan control in Arch and so fan control stays at BIOS-level, which might also read out a different sensor / the same sensor differently or it might be more conservative in setting fan speeds altogether;
OR: You have something that provides fan control installed in Arch and it reads out a the wrong value supplied by lm_sensors and thus sets a higher fan speed.
Anyway, possible solutions I can think of:
Find out if you have some kind of fan control software and what it does. For example, I use the fancontrol daemon, I can't help you if you use something else.
The wiki mentions how to assign a fan speed to a certain temperature sensors. You might assign it to a different one. For example, there are no sensor chips on the mainboard of my EEE (no temp1 etc.) so I assigned the fan speed to the temperature reported by the BIOS via ACPI (those are in /sys/class/thermal, also no "device" subfolder on EEEs):
FCTEMPS=/sys/class/hwmon/hwmon0/pwm1=/sys/class/thermal/thermal_zone0/temp
You could also change the MINTEMP/MAXTEMP values to one higher than those you actually want to compensate for the effect of lm_sensors reporting temperatures that are too high.
It is currently not possible for a mortal user to change the coretemps lm_sensors reads, see this post, last paragraph.
There is a configuration file, /etc/sensors3.conf, you can change sensor names and adjust offsets here, but only for the monitoring chips and their sensors that are on the mainboard.

What is the correct way of quieting down the CPU fan?

Hello,
Let me first ask for recomendations on an aftermarket CPU Heatsink and Fan to replace the stock one on my AMD x4 965 Black edition CPU please, My profile on this forum has my computers equipment and case etc. But if you need more info please just ask..
Would somebody please give me instructions on how to make the stock CPU cooling fan run at a more appropriate RPM when at idle and or when running with a load on it please.
The stock CPU cooling fan usually runs up there at about 5,000 to 5,500 CPM even when at idle and it's seriously insanely loud, too loud to be sitting next to it and trying to concentrate on work or even playing a game.
I've been loading up the Overclockers Center program and choosing the default profile since that seems to have the CPU fan set to around 3500 RPM which produces an acceptable noise level for the fan. But I figure that having to load up Overclockers Center program and choosing a profile each time I load my computer is probably not the way I should be doing it, so if somebody wouldn't mind, please explain what I need to set in the Bios or elsewhere so that the CPU cooling fan is not blowing my head off with noise all the time.
Thanks

Hello
1-This mobo is strong enough to support such a heavy coolers.Now i have i installed TUNIQ TOWER EXTREM( because of porformance/price here) that is as heavy as v8. although the company dosnt gauranty the failure but it works very well on my case and i rotate and opening the case many times for some experiments!!
2- ZALMAN is a famous cooler producer.I said the rules for choosing a cooler . You can buy one of them .The reviews on net can help you for best choise.BUt v8 is a good proven cooler because the more surface that has and material and big fan.although i didnt have another choice in IRAN.You may find so better coolers.
the fluid mechanic rules say that the surface-material-shape of heat sinks and temperature-velocity-amount of air that moves on the heat sinks are the parameters of a heat sink.
i have a bad experience.In my old case with P4 3 GHZ i bought a good cooler from THERMALTAKE .But the fans is rotating very much and made noise. There was some truth that i didnt mentioned.
The cpu is produce a lot of heat ( more than phenom) and the fan is 10 cmm i think . I replaced the fan with a 12 cmm fan but the system in loads crashed. The heat sink designed for such a fan and it must rotate very much to cool cpu .12 cm fans cant go beyond 2000 rpm i think and this amount of air wasnt enough for cooling.
3- you have a lot of wind in your case!!. I dont know that greater fan than 12 cm is safe because they use more current .But 8 and 12 cm fans works very well with onboard ports and SPEEDFAN program.
After all cooling and making the pc make less noise is a long story .You must have a target . There is a limit that you cant go beyond that so i think you must have a plan and use your money and time on it.
For my new system i had a dream: most powerful-silent-upgradable system so i choosed these parts:
POWER=CM SILENT PRO- for the design and big fan that they have.
CPU=ATHLON II 635 -I knew that phenom is very powerful but make more heat so i used this cpu and have plan for upgrading with a 6 core cpu.
VGA= 1-GIGABYTE 9800GT SILENT
2-ZOTAC 9800GT SYNERGY
choosing a gpu was very hard. 9800gt silent was the most powerful silent cpu that i could buy. but for future i bought a zotac. because it has a single cooler and dosnt occupy a PCI slot that i need.
you may say why you dont buy another 9800 silent? because this card is warm in loads and i had a fear two of them in a case may harm them. I count on HYBRID SLI technology that could shut down the second card but it is not working and i am a little disappoint .
two 9800gt in sli have as power as a GTS 270 in reviews.
CPU COOLER=TUNIQ TOWER EXTREM- According to my counts cooler was silent in ideal but in loads it was noisy so i replaced that
MOBO=NF980-G65-It uses the last chipset from nvidia with sli enabled and ddr3 and phenomii x6 support. (The mobo is hot. According to some reviews it is cooler than AMD chipset motherboards and faster but i hope it was cooler)
Good luck

Cpu fan 90B alarm and plugged in but not chragiung alarm

hi,
I have HP notebook product: b6u29pa#acj and model: g6-2101TX.
I am getting following problem:
A. while start up pc i found alarm 930B cpu fan failure and then after restarting window7 start.
B. many time when i put laptop for changing it shown plugging but not charging and led near to charging port keep on biking white colour. that time charging not happen so if i removed charger and keep on using notebook my battery level is not getting down and suddenly at one point notebook power off. That means battery getting used but notebook not getting understand and giving me battery low alarm. Then i have to remove battery and insert it again. it will work for 2-3 days n then same problem repeat.
( pl note that note book battery is good and giving 2-3 hours backup when fully charge)
Both my problem was chronic so i took photograph when problem came and then given laptop for repair at service centre as it was under warranty.
Then next day i received call from service centre that my laptop ok pl come and collect. so i went to service centre when i checked found same problem so they took back and said motherboard is faulty.
for CPU 930B fan alarm they only clean fan may be alarm will come in few days.
after 8 days yesterday i received call again from service centre that my laptop is ok.
now my question is if my laptop is not ok then what to do? as my warranty was exp. on 23.08.2014 ( i need few days for trial ) may be after replacing motherboard any other problem appear. Will HP give few days for trials?
or any government intervention is required ?

Hello @yoursviru ,
Welcome to the HP Forums!
I understand you have issues with charging and a 90b fan error on startup.
To address your question about a trial period after repair: Typically the repairs should include a 90 day service warranty or the remainder of your existing warranty whichever is greater. This depends if the repair was done by HP or an authorized HP provider. HP Phone Support can confirm this for you.
If the repair was not done by HP or an HP service provider HP cannot guarantee the work of third party companies.
The power not charging the notebook could be an issue with the battery, internal power connector cable, power adapter, or motherboard. All of which are hardware related.
You can read about the fan error here and what to do to fix it: System Fan (90b) error message on startup.
To sum everything up. I suggest you get in touch with HP Phone Support as soon as possible as they are the ones who can give you a straight answer regarding service and warranty questions. My answers are based on personal experiences, as the forums do not offer service and are available regardless of the warranty status.
Hopefully Phone Support can give you the answers you're looking for.

K8N Neo-FSR CPU fan at full throttle after wake up from S3 (Suspend to RAM)

Hi,
using either Core Center or BIOS' smart cpu fan control my cpu fan throttles down to less than 2000 RPM without system load. Fine! But after wake up from S3 (Suspend to RAM) power down the cpu fan runs forever at full throttle with about >5000 RPM, making lots of noise. So far I didn't succeed neither with BIOS settings nor using Core Center to gain fan control after S3 wake up. Since Core Center apparently shows up the cpu temperature correctly with less than 40 degrees Celsius this may be a BIOS 1.4 bug.
Can someone please point me into the right direction? Yep, I did read the FAQ and already use board's search function :-)

addendum
did some further testing. Apparently this doesn't happen if I wait at least a couple of minutes between shutdown to S3 and wake up. In this case fan control works as expected afterwards.

Connet cpu fan power to m/b or psu?
