[Solved] lm-sensors fan speeds and voltage.

After installing lm-sensors and running sensors-detect I have the following readings from sensors;
~$ sensors

Adapter: Virtual device
temp1: +42.0°C (crit = +80.0°C)
coretemp-isa-0000
Adapter: ISA adapter

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +42.0°C (high = +78.0°C, crit = +100.0°C)
I am sure in the recent past I was able to retrieve fan speed and voltage readings from this machine;
|Abit FP-IN9 SLI | Intel(R) Core(TM)2 Duo CPU [email protected] | GeForce 9800 GT |
I suspect this is something that I am doing wrong (or is it a kernel issue??) as I have the same problem on a similar machine running Ubuntu 10.04.
Any ideas appreciated.

Hi graysky,
You were spot on!
I followed the instructions in the wiki article to add
acpi_enforce_resources=lax
to /boot/grub/menu.lst
Reboot...
Voila!

Fan Speeds, and Mirror Raid with New Internal Hard Drive

Regards,
I recently installed and formatted a new hard drive in my PowerMac dual 2.3 ghz computer and I have a few questions.
1. Now that there are two hard drives do I need to do anything to ensure that the fan on my computer can keep them cool? I think the fans I have in the hard drive bay is enough, but I do not know if they will automatically set themselves to run properly. I can monitor the fan speeds and temp from iStat pro, but do not remember what level the temperature was before installing the new one.
2. Given that my new drive is a SeaDisc hard drive and the older one is a Western Digital, will this cause any problems in creating a mirrored RAID. I believe that both are 7200rpm drives, and my second hard drive is a little larger (I will just have unused space after making the RAID). I am concerned with the fact that these two drives are from two different manufactures. Will this cause problems or drastically slow down the reading and writing of data? Has anyone else experienced problems in making a mirrored RAID from two hard drives that are not exact matches, and even come from different manufacturers?
Any advice will help.
Thanks
earpshmael

Hi earpshmael;
Generally when creating RAID arrays the more similar the drive the less problems you tend to have.
The real question is exactly why do you want or need RAID?
I think so many people seem to think that RAID will solve all of their problem. I hate to tell you the bad news but it will not.
Generally there are to varieties of RAID available using the software RAID built into OS X which are 0 and 1. RAID 0 or stripling is generally for moving large file rapidly for applications like HD video. It usually doesn't help the OS. RAID 1 or mirroring is for protection from drive failure. It is not a valid backup solution.

IMac (early 2009), 3.06 GHz, ATI 4850 - fan speed and temperature questions

Well, so I downloaded and installed Temperature Monitor and iMac Fan Control - mainly for observational purposes and not for toying around with the fan speeds and I've got some questions. Mind you, I haven't tampered at all with the fan speed settings, just installed Fan Control. Here are my readings (while browsing the internet with Safari and doing a chat via iChat):
Fan Speeds:
CPU fan (desired) 1300 RPM / (current) 1530 RPM
HD fan (desired) 2100 RPM / (current) 2099 RPM
DVD fan (desired) 1300 / 1298 RPM
Temperatures:
CPU Heatsink: 92°F
Internal HD: 108°F
Internal DVD: 95°F
GPU Heatsink: 107°F
Are these, under the circumstances, normal readings?
Thanks in advance for your replies.

Your welcome and no problem. I would say only the Apple engineers can tell you why the fans are set to those speeds however my best guess is the obvious they found those speeds the closest to keeping the temps at an optimum operating temperature. I found when I'm doing graphics intensive work my machine heats up but quickly cools down when I'm done.

MSI 5900XT-VTD Fan speed and GPU Temperature

Hello,
I wonder if someone can tell me how can i know the temperature and fan speed of my MSI Gforce FX 5900 XT-VTD.
I have installed 3D Turbo Experience (MSI utility) but when i get the window,i'm only able to see the Core and Mem Speed(I can modify them).The fan speed and core temperature are not active.....
Is it normal ?..

that card doesnt surport monitoring of temps and fan speed

What are you using for Fan speed AND temp monitor?

Thanks to Bosskiller, my rig seems to be running a bit stabler now! Knock on wood. Is there any program other than MSI's core center that monitor fan speed AND temp? I used to use MBM but it's no longer being supported and CoreCenter doesn't seem all that popular here?

Actually how accurate is the temp reading on HWMonitor for your MSI board? One thing I noticed is that w/ Coretemeter the temp reading was around 48-50c on Rig#1 and almost 58-60c on Rig#2 (That's my HTPC w/ EXTREMELY tight spacings so still work in progress as far as cooling's concern!) but using HWMonitor I got 31c CONSISTENTLY on both rigs! I'll love to think that I'm indeed running this cool but feeling the exhaust air, I think this 31c reading is not real...

Tweak the balance between fan speed and CPU temperature / Dell M6400?

Hi all,
I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that

When I start the laptop, its CPU fan stays at its minimal speed only for 1 or 2 minutes, then increases its rotation speed to a second level. It reaches it maximal speed only under heavy load, when the CPU reaches >80-95°C. I would rather let the CPU run a bit hotter before the fan starts to blow: let's say the fan could enter its intermediary speed between 70°C and 85°C instead of 55-80°C, and blow at is its maximum speed beyond that.
I checked the Fan Speed Control wiki page, but lm-sensors is not able to show me the status of the fans. Any idea ?
Aurel.
PS: the temperature of the GPU is not reported by sensors, and nvidia-settings reports around 60°C. Its dedicated fan is very quiet.

Hi aurelieng,
I'm in the same situation from at least 1 month ( INTEL CORE 2 EXTREME X9100, 3.06GHz with 8GB ram, one solid state disk 128 GB, and one sata disk 500GB)
My dell M6400 has dual boot: ubuntu and windows7. The fan works a lot and continuosly in both environment and this is the reason because I have doubt that the origin of the problem is in hardware problem?

Kernel_task high cpu usage, high fan speed, and low cpu tempterature

Hi,
I've noticed that a lot of people have been having trouble with the kernel_task process, but I couldn't quite find a situation similar to mine (most seem temperature related).
Here is the situation (15' MBP, mid-2010):
- on boot (while the apple logo is shown), the fans speed suddenly jumps, and stays there, even if the computer has been off for a while.
- boot takes a little over a minute, which is considerably slower than what I was used to before today
- when finally started-up, the activity monitors shows kernel_task using between 160-180% of the CPU!
- temperatures are shown to be around 30C, except for the mem controller at 40C (still very low temp), but the fan speed is arround 6000rpm for both fans.
- this happened out of nowhere, as I woke the mpb from sleep this morning.
Since then I've tried:
- multiple reboots
- install all updates
- uninstall flash player (some people where having trouble with that)
- empty the system cache with Onyx (reported as a cause of slow boot)
- reset PRAM
- reset SMC
- put some ice packs under the mpb to cool things even further!
And so far, nothing has worked! I've had this laptop for 1 year, and nothing had ever failed. I upgraded to lion a few weeks ago, and everything had been working fine since the upgrade. This really happened out of nowhere, and none of the many forums I have read could offer a solution, and cals to apple support do not seem to yield better results (though I scheduled a call with them at 9am this morning, we'll see).
Has anyone had a similar set of problems?
I appreciate any help or advice you may have!
Thanks!
-Sebastien

I have the same issue (2.66 2010 MBP Hi-Res Anti Glare.)
I took it to Apple Store Covent Garden, JUST within warranty.
18 days later my machine has a new Main Logic borad, heat sensors, top case, palm rest. etc.
I turned it on.
The fans kicked in. All processors at 50%, big ole kernal task.
I took it back, geniuses rest SMC and tested it under load and it was fine.
weirdly it failed diagnostics at first but then seemed fine
I came home. Fans kicked in...
I took it back. Diagnostics failed heat sensors again
Replaced logic board and heats sensors again, but more carefully this time just in case, tested again.
I took it home. FANS FANS FANS.
Last time I was in the store I was told my machine was fine and had been thoroughly tested.
In mac store, no fans.
I erased hard drive and clean installed Lion
FANS
I replaced hard drive with OCZ SSD, clean LION.
Fans
Software update
SMC
PRAM
permissions
Onyx complete clean/maintenace
FANS/CPU
switched back to Snow Leopard SSD
PRAM SMC ONYX etc.
FANS/CPU
replaced RAM, memtest-ed. fine, FANS
gonna try again but up to nearly 2 months of all my spare time trying to shut this thing up so I can sell it.

SOLVED: GTX 770 Fan Speed Stuck at Full

Ever since I set up my GTX 770 in my computer, the fan speed appears to be set on full constantly. I have tried to use MSI Afterburner to solve the problem, but to no avail as adjusting the fan speed curve in Afterburner seems to do nothing. As soon as it boots, the fans ramp up to what sounds like max and stay like that. I was wondering if there was anyone else with this problem and if I can fix it.
Thanks in advance,
muddyducky
EDIT: Turns out it was actually every other fan in my computer running at 4000rpm that caused it - managed to turn it down in MSI Control Centre :P

Do you still have a question/problem?

Imac high fan speed and goes to sleep 10sec after wake-up

Hi,
Since today my imac's fan speed is high (optical fan and cpu fan speed at: 4000rpm)
Done a hardware test wich gives me 4SNS/1/40000001:IDSR-0.000 indicating something with logic board. According to istat all my temperatures are below 35°C (95°F). istat has readings for the cpu and optical drive temp (both around 26°C)
On top of that if I put my imac to sleep after wakeup (give or take) 10sec later it would go to sleep again. tried the smc reset procedure. no success
Any other tricks to try or just go for an exchange? (imac was bought on 2feb2010)

I've had this problem since replacing the MLB in my iMac a few weeks ago. Initially brought in for repair when the CPU fan came on at 4k rpm and stayed on even after SMC reset and nvram reset. First replacement MLB was a dud, second corrected the fan problems. Now I'm having the sleep issue, I can't tie it to any particular process. Initially I thought it was graphics related as it would go to sleep during graphics intensive work, but yesterday it was doing it when just copying data to an external drive. The temperatures of the CPU and the GPU diode are within spec. I now use a fan controller to keep the CPU fan at 2100rpm and the HD fan at 2100rpm and I don't have the problem. From what I can tell now is that a sensor is incorrectly reporting temperatures intermittently. It may not be the MLB or the graphics card specifically, but the cable connecting the sensor to the board. I ran AHT after the last time it did this and it failed a sensor, but after running ASD on the machine it passed all the hardware. I'm bringing it back into my shop later this month and if i can remember i'll post here with the resolution, not much I can do at home beyond software diagnostics.

Problem with Sensor fan 3 and 4 (P67A-GD65

Hi all :D.
I had buy 1 week ago a new P67A-GD65 motherboard but i have found a problem .
Today, i have connected my 4 fan in three different slot fan.
When i look with EFI the rpm of the fan,i can look only CPU_FAN SYS_Fan1 and SYS_FAN2 but not for SYS_Fan3.
Where is the problem? Sensor? Or what?
I had try to use AIDA64 and SPEEDfan but same problem

Not all Fan headers support fan monitoring & fan speed adjustion. That is not a bug but rather the lack of a feature.

[SOLVED] ACPI sensors & fan

Hello everyone.
Months ago, with Debian Squeeze, I tried to control the speed of my fans, but I had no luck: pwmconfig said There are no pwm-capable sensor modules installed. It's the same now with ArchLinux.
I'm using a custom kernel, compiled from the linux-ck AUR package, with ACPI enabled. The funny thing is that disabling ACPI in boot options (i.e. acpi=off) leaves the fan at its maximum speed; that way, the temperature is stable around 60 ºC. With ACPI enabled (both with and without the fan ACPI module) the fan is off until the temperature reaches 95ºC; then it starts at maximum, downgrades it to about 70ºC and offs again.
My question is the following: is ACPI needed in some way? I never suspend/hybernate the system. I don't need power management since -although it's a laptop- my computer is always connected to the AC without battery. I don't want CPU frequency scaling; I want my system to be full performance.
Or, if disabling ACPI is not recommended (as I have read somewhere), is there any way to tell the kernel to start with the fan when the temperature reaches a certain value?
My laptop is HP 6735s. The output of sensors is the following:
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +88.8°C (high = +70.0°C)
(crit = +100.0°C, hyst = +95.0°C)
The processor is an AMD Turion (tm)X2 Dual Core Mobile RM-70. I use the k10temp kernel module to fetch temperature information about it.
P.S.: With the core repo kernel, there are no such problems with the temperature, although I would still prefer the fan to be more active. I believe there's no problem with that, is there? I bet it's better having the fan working at full speed than burning the CPU or the graphics card (the hottest components of my PC).
Thanks in advance. Best regards,
Kalrish
EDIT:
I've just found this thread, very close to mine. So I have some files in /sys, that seem to define the limits and the behavior of the fan according to CPU temperature values. I've tried modifying them (as root, of course), but got Permission denied! Maybe that's not the way to go? How can I tell the kernel I want fan speed at maximum until the CPU is about 50ºC? Aren't there any tweaks, configuration files...?
Last edited by Kalrish (2013-04-03 15:44:23)

I have finally found the issue.
Con Kolivas suggests having no CPU frequency scaling and letting the BFS do all the stuff (I may have misunderstood something…). It's here (I followed several desktop configuration suggestions as I do not use the battery at all).
So I disabled everything related to the processor and frequency scaling: the cpufreq kernel architecture *and* the ACPI processor module, which, in fact, implicitly disables the [ACPI] thermal module. That module was responsible of creating a virtual device, whose output was the same as k10temp's.
With that 'device', the fan works "properly" (as I said, I'd like it to be more *active*). Without it… well, 95 celsius.
There must be a problem with k10temp. I thought the kernel was responsible of choosing the speed of the fan according to the temperature it read from the appropiate modules/drivers… or maybe it's ACPI!
I'm confused. For now, I'm going to check the source code and try to understand a bit (sensors outputs some limits related to the kernel module, that I tried to edit via /sys without luck).
Thanks to everyone!
P.S.: I just want my system to have the best performance it can offer. Of course, I don't want to damage it (no overclock. Never) but… is it harmful to let the processor run at its maximum frequency? I think not, with the appropiate cooling support.

Fan speed and CPU temp

Hi There,
I have MBA 13'' Mid 2011.
I'm little bit concerened about Temp of my CPU which is 96°C, and Fan speed is around 6500rpm.
I can hear my fan all the time.
It was not like this always and i'm kind of sure that something is causing this.
I worked before with lots of apps open (itunes, photoshop, text editor, chrom, mail, parallels..) and fan and temp was not this high.
Is there way to find out what is causing this high usage?
Thanks in advanced

First execute a SMC reset:
http://support.apple.com/kb/HT3964
If no change, install istat menus.
http://bjango.com/mac/istatmenus/
Open Activity Monitor to ALL PROCESSES and CPU. Make certain that CPU displays values from high to low.
Post images of both istat menus and Activity Monitor whe the MBA has heated up.
Ciao.

3d Turbo Fan Speed And Temp Readings

Hi
I am just wondering if this is normal for a fan speed 3478 when the default is 3500 and I find the TEMP is high 52c idle. My video card is a Ti4200-TD8X (ms-8894)

That's pretty normal.
What is the case temp and room temp?
Mine read the same rpm at 45c, but it was 10 degrees cooler in here during the winter, I suspect it's right around the same.
No worries, now you can uninstall the 3d turbo and forget about it. You are one of the very few on this forum that program works for 8o

About the rules (logic) between the fan speed and the temperatures?

Hello All,
Well, I've had a bad experience with my MBP last week: my motherboard busted and had to replace it... Expensive part to replace!
After thinking about the reasons why it failed, my attention has been directed toward a possible motherboard overheating, which might have damaged the motherboard.
I've installed the iStat Pro widget and regularly monitor temperatures displayed vs. fan speed. I do get a bit nervous when I see a 84 oC CPU temperature and idle (2000 rpm) fan speeds. My GPU temperature is also sometimes in that range.
My questions are:
1) does anybody know the rules (logic) between the various temperatures (CPU, CPU heatsink, GPU, GPU heatsink, enclosure, HD, etc.) and the fan speeds?
2) other than with the fews apps out there, is there a way to customize the rules? Is there a text file or a plist file somewhere where I can change the rules?
Thanks!

If your idle speeds are 2000 rpm, you have one of the original Core Duo MBPs. For me, I see fans on my 17" CD MBP speeding up once temps get into the upper 70s °C.
Apps like smcFanControl allow you to alter the setpoints. Note that some users who installed smcFanControl, then uninstalled it, report symptoms like yours - namely, the fans remain at idle no matter how hight the temps get, until a thermal shutdown is triggered (somewhere close to 100 °C).

Fan speed and CPU temp viewing Flash video in Firefox vs. Safari ?

My MacBook (two months old) running the latest Safari version (3.1) seems to be working unbelievably hard when viewing a flash video. The temps seem to cycle between the high 60s and mid 70s, and the fan blows at max speed constantly. On the other hand, when viewing the same flash videos using Firefox (2.0.0.12), there is only a slight boost in temp (high 50s to low 60s) and the fan speed hardly increases at all.
Has anyone else noticed this?
Why would the flash player on one browser be so much more efficient than another (Safari seems to labor, while Firebox breezes along)?

Thanks!
Well I guess the code in the Safari browser just wasn't well written. This is true even of the later version of Safari. It does work much better in FireFox, with no crazy heat-up or fan action.
I've pretty much given up on Safari now on everything by my iPhone and iPt, and only because I have no other choice.

[Solved] lm-sensors fan speeds and voltage.
