Fan Sensor

Hi, Just bought a new Zalman FS-C77 Fatal1ty fan for my Cpu. Plugged it in and my sensor doesnt detect it. So i thought maybe the fan didnt have a sensor or sumthing, went out and bought Zalmans Fan Mate. Still no reading about Speed Fan. Plugged it in all correctly( i.e sensor to sensor, ground to ground) but still no reading from Speed Fan. Checked my bios for the fan speed and it was there. running at normal speed. Is this because Speed Fan Doesnt support K8N Ne0 4 Platinum?
Thanks in Advance

It does support it. You should also be able to change the cpu fan speed as well.

There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.
anyway i managed to control my system fan to monitor temp1 (motherboard temp) running:
echo "180" > /sys/class/hwmon/hwmon2/device/pwm1
but i need to run it as root and pass "yes" to pwmconfig first to activate manual control
so i need a bash script to run this automatically on startup,i found this one and modified it but i need help to get pwmconfig run with "yes" before start my if...else control to launch "echo..." once temp1 reach 50 C°

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.

No temperature sensors found and no fan sensors found

Today when I opened my iMac, I was surprised that iStat found none of the temperature and fan sensors. Yesterday, everything was working well. Coincidentally, my mac was making a loud whirring sound that gets annoying. What should I do?

I would suggest resetting the SMC first by shutting down the machine, and then unplugged ALL cables from the iMac including the AC power and letting it sit for at least 30-60 seconds.
Plug the AC power, mouse and keyboard back in and turn it back on; see if the Fans are reported in iStat now.
Post what your various temps are once you get it back up.

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.

No Fan Sensor Found No Battery Found Doesnt Sleep when lid is closed?

I have a late 2006 model MacBook Pro and this past week the battery doesn't show up on the menu bar, so I cannot see if it's charged or not (except the LED's at the bottom which indicate it's full) but more importantly, according to iStat, there were no fan sensors found, and the fans sound like they are running full speed with no slowdown from start to sleep. And I now have to manually put it to sleep and I didn't change my preferences to do so. Before I spend what would most likely be more than what the thing is worth, I wanted to know if there's anything I can do before I take it to Apple?
I'll take whatever you can offer as I rely on this computer for school, home, and work!
Thank you so much in advance!

Hi b, and welcome to Apple Discussions.
Try an SMC Reset. Also take a look in System Profiler to see what it says about the batt condition. If neither of these help, boot from the install disc with the Apple Hardware Test on it (hold down the d key) and see if it finds any bad sensors.

[Solved] Overheating/fan/sensors issues after kernel updates

Hi all,
I realise there has been a bit of correspondence on this already. I'm after some advice for my specific situation:
1. My laptop is an acer aspire 5315. I has well understood overheating issues that arrise due to BIOS problems
2. Fan control and temperature reporting worked perfectly with kernel 2.6.30, stopped working with 2.6.31 - I assume due to the well documented changes made in that release. The temperature only seems to be read once - at boot. sensors never reports a change after that; if the temperature is cold at boot the fan never get switched on. Unfortunately this happens most often.
3. I tried setting the recommended kernel option (can't relocate the post now). It didn't help :-?
4. I have tried upgrading the BIOS but the distribution from acer is a windows executable (won't run under freeDOS) and I do not have windows installed on this PC (not game to try under wine).
5. I re-installed the old kernel from my pacman cache only to find that my wireless no longer works (fan works just fine though).
I'm now totally stumped :-/
I'd like to update my bios and go with the latest kernel but can't see a way without installing windows.
This might be fixed in an ubuntu kernel release (https://bugs.launchpad.net/ubuntu/+sour … bug/453700) but I'd prefer not to do that switch... perhaps the same fix is coming to arch?
I'd accept having to pin the kernel to an earlier version but neet to get the wireless working.
help...
edit:
I've now managed to get the kernel backdated correctly (so that wireless works as well as the fan) by re-installing the kernel and firmware together.
Have configured pacman to igmore future kernel updates
If anyone has any suggestions on howto update my bios I'd be very greatful.

Hi,
Got exactly the same issue, after running for a while laptop justs goes off... going to try to regress kernel until issue is resolved
BIOS update does sound a bit extreme
MrG

Fan sensors changed? (thinkfan)

Hello all,
after some days without an update on a Thinkpad I did it yesterday and the fan spinned around. Thinkfan was'nt starting. With one of the last Arch updates the addresses of the thermal sensors were changed. I'd like to know more about it. Which part caused this change?
(My thinkfan is configured well again, that's not my question. I wanna know about the chage of addresses.)

Probably a kernel change, check /var/log/pacman.log for that.

Fan/sensor problem. Please help! 4SNS/1/4000000:TsOP

Hello people,
I have the fans of my Santa Rosa 2.4MBP constantly on at 6000RPM. Hope the problem is the thermal sensor... But which of them???
Apple Hardware test shows an error:
4SNS/1/4000000:TsOP
I can't send the laptop to the Apple service center, for it's pretty far away from here. And I would fix everything myself, rather then paying those guys.. I mean I am qualified enough with assembling and disassembling this MBP and changing a sensor doesn't sound as a scary task.
Please tell me it's not the logic board, that got in trouble.
Thanks!

A thermal sensor lead to the motherboard has come off (or the sensor has failed) and so it runs in 100% fans on mode 'just in case' to prevent any overheating issues.
If you're careful and competent you could check if one of the leads is off yourself but if the sensor has blown I think you'll need Apple to fix that. (Pics to help you along)

Motherboard FAN Sensors

Hi,
I am not sure if this happened all along, or only after I installed the CoreCenter.
My current system consist of P4 3.0 (with HT), MSI 865PE Neo2 Series Motherboard, 2GB RAM. Graphics Card is ATI 9250, 1 Creative Audigy Platimum. I have 2 SATA hdd, WD500DB and Seagate 250GB. 1 IDE WD200GB, 1 TDK 40/12/48B and Benq DW1670. The PSU is seasonic m12-2 430w, newly acquired). I did not do any overclocking, i.e. did not install CoreCenter, until recently.
After I installed the CoreCenter, out of the blue, it will trigger off the alarm that the CPU fan is not running although I can still see the fan spinning well. All the fans (CPU, 2 casing fans) in the system at that time is reported to have 0 RPM. Is it because motherboard is dying, or it is an issue of the Software that cause the senor to malfunction?
Please help. Thanks in advance.
Regards.

Quote from: Jack the Newbie on 02-April-09, 23:44:58
Uninstall Core Center completely. Can you see anything about fan speeds in BIOS (H/W Monitor)?
Install SpeedFan and Everest Ultimate (latest Trial Version) and check what they have to say about your fans.
I did install the sensor view. At the time of failure, the sensor view also display the fan RPM as 0. After I restart the server, every thing goes back to normal. Strange.
Anyway, I have uninstalled the CoreCenter, and installed the SpeedFan. Will carry on to monitor the system.

Speed Fan sensor ID's on Neo2 Platinum

Can anyone give me a clue to what the sensor labled "Remote Temp" in Speed Fan is reading?
It's got me kinda concerned, because sometimes indicates temps that are nearly as high as my CPU! & that wasn't the case until very recently.
In the "Configure" screen it reads like this:
Label Chip Sensor Sample Bus Address
Remote Temp MAX6648 Remote Temp 37C I2CNvidia SMbus $4C
Thanks!

Winbond sensor3 is not connected to any external sensor on motherboard , and any temp on this one is bogus.
The mobo has two valid connections to winbond chip nvidia-chipset & cpu , no case sensor .
Winbonds connected are :
Sensor1 chipset
Sensor2/diode cpu
In my case with SpeedFan 4.20, sensor #1 is obviously bogus as I'm reasonably certain that my chipset isn't running @ 9C... Sensor #2 has been verified as "the real deal" as CPU, however. Maybe they've been reassigned/relabeled in this version. Sensor #1 WAS cpu in version 4.17 of SpeedFan.
Quote from: Tiresmoke on 14-February-05, 01:45:20
The MAX6648 is the sensors on the NVidia card. I never even saw that sensor until I installed my vid card and there they were.
As far as the "MAX6648" sensors go - I know that neither one of the values denote Vid core temps, which are 43-45C. As reported by temp utilities by Nvidia & Riva Tuner. Perhaps one of them is an ambient temp sensor of some sort or that SpeedFan is flat reading them incorrectly....
I know it's all academic anyway.... My "box" is reasonably dust-free, all my fans are running, there are no malfunctions (out of the ordinary anyway... it IS Windows after all!) & I don't smell the distinct odor of "electronic expiration".

Fan sensor broken ?

Hello,
I have an iBook G4 800 MHz. Since 3 days I have the Problem that the CPU temperature is at 72 Celsius when I'm not working. First I’ve thought that the fan is damaged or not functioning. I have try to start the apple hardware test cd, in this program the fan is working right. I am now very sure that the temperature sensor is broken.
Is there any possibility to control the fan manually, or to set the rotation to a specified value?
I’ve found a website in the net, where i can set the AppleFan.kext to other values. But is his effectful? or illegally to manipulate this file?
Sorry for the bad english!
I hope you can help me.

Hello John Huber1,
thanks for your fast reply. You are right. At the 6 June I have insalled MySql and PHP for a school demonstration. Later I configured the sql server again and there was an error in the ini file, i have quit the process but i have not thougt on it that the process is starting with os x. And now the sql server were restarting all the time in affect of the wrong ini. I am so stupid...
One wrong configuration, but a big effect.
Very thanks for your help.

Z87-G45 CPU Fan Sensor Malfunction

Seems like pretty much a non issue but none the less I want to figure this out. When monitoring fan speeds on the MSI Z87-G45 Gaming motherboard it keeps reading zero, then returns to a normal level, then reads 0. I noted this even in the motherboards on utility accessed before allowing windows to load and again using a 3rd party monitoring program. I'm going to assume its a faulty sensor but I'm just not sure. Anyone have any ideas?

Quote from: badboy2k on 19-July-14, 14:08:55
the stock coolers with Processors suck and are only meant as basic cooling (if there under load they get very hot and the fan spins at 100% which on them sounds like a jet engine) i too would change that for a good after-market one!
My I5-4590 hovers around 30C idle, and stays under 60C under gaming loads with the stock cooler ... even with more CPU intensive games, so, they do work well if everything is working correctly..... possible that his CPU fan is getting ready to fail.

IMac fan / sensor problem

Hello!
Some days ago I automatically sent my iMac to sleep via the "Energy Saver --> Schedule" menu in the systems preferences. When I woke it up the next morning, the CPU fan didn't just blow once and ran quietly in the background as usual, but it keeps blowing at max. speed which is really loud and annoying.
So I went to search for the problem and found it right away possibly: the GPU heatsink temperature sensor constantly reports 126-127 degrees Celsius, which is quite impossible I ran the quick hardware test with the startup disk and got the following error code: 4SNS/1/40000000: TG0H-127.875 - which indicates a sensor problem as well I think.
My question is, if there is anything I can do to regulate the fan or the sensor by software. All I found was several programs that can regulate the minimum rotation per minute, but not change the maximum. As there isn't really much damaged (as far as I know now just one out of three GPU sensors), it would be really annoying to have to let it repaired. I'm not playing graphics intensive games, so it won't ever get too hot.
Anyway, right as it is now, it just freaks me out and just leaving it that way is clearly not an option.
Thanks for your help
Michael

Yes I see what you mean all the other temps are fine so I think your original guess of a sensor problem is probably right. You are covered by warranty so I'd contact Apple to complain about it. BTW if you haven't already I would recommend purchasing AppleCare before your 1 year warranty is up.

Elitebook 8570w hot to the touch, can't find fan sensor data

Hi, I am having issues with a HP Elitebook 8570w and its functioning. When using a lot of the cpu the heat builds up to the point that it can get slightly painful to the touch on the left side. This includes the left most keys of the keyboard. The fan itself is nearly silent and there is barely any airflow through the exhaust. But can be heard to be moving. The laptop itself is inclinded and the fan doesn't look blocked when inspected through the service latch. The only physical block I can imagine is with the side exhaust but I can't examine that without taking apart the entire thing. So I am trying to diagnose the situation. However I have not been able to find any way of monitoring the fan speeds and utilisation. (SpeedFan and its ilk appear to be unable to find a fan) Do I need to go into the bios for this? As I'd rather not send it in just for a software issue. But with temperatures around 90-120 degrees celcius I'd really like to do something about this.

MY suggestion would be to send the unit for service if it is under warranty and get it fixed. If the unit is not under warranty then please check the vents and clean it since i belive it should be blocked . I am a HP Employee. The comments made reflects only my idea/knowledge and not HP.
