Fan Speed after standby

Hi,
I control the CPU fan speed with the bios-settings (max. temperature 60°C, +- 5°C). This works fine as long as I don't use standby. As soon as the computer resumes from standby, the fan is always running at maximum speed, regardeless of the cpu temperature. The speed control doesn't work any more. Thus I have to use softwaretools (CoreCenter,...) to reduce the speed.
As I don't want to have this annoying piece of software running I am looking for a bios-only solution.
Anyone found a solution for this problem ? Seems to me as if it was a bug in the bios.
Greetings from Vienna,
Markus
Config:
MSI K8N Neo2 Platinum
Athlon 64 3500
Bios v1.5 (same with 1.4)
Sapphire Radeon 9600 graphics adapter, no fan
1 GB memory
1*160 GB Samsung HD
1*120 Seagate HD
1*80 GB Seagate HD
Technisat SkyStar2 sat-receiver card

I have the same problem but the difference is that my fan speeds up the moment i boot my comp. Corecenter doesn't fix this! It displays 6200rpm ! Weird ! Coz the specs of the fan are 5200 if i remeber correctly !
I fix this problem by loading Windows Task Manager (Ctrl+Alt+Delete) and then CoreCenter! The moment that CoreCenter Loads, the fan drops at normal speed and then from the Task Manager i kill CoreCenter and the fan remains at normal speed !
Of course I need a better solution than this, but can't find any ! I haven't updated the bios or any MoBo drivers !

Can't control fans speed after upgrading to kernel26 2.6.31 [solved]

Mother board is ASUS P5Q-SE. After upgrading pwm sensors disappeared. I can get temp and fans speed but not set. Any ideas? :-\

"This works for me" is a little vague. What worked for me specifically was to start with your link and drill down two levels of links to this webpage, http://hansdegoede.livejournal.com/7932.html, which explained what the problem is and that the workaround is to add acpi_enforce_resources=lax to the kernel command line in /boot/grub/menu.lst.
Someone who understands this issue better than I do should probably amend the appropriate sections of the wiki (lm_sensors, fancontrol, et al).

Processor speed after Standby Mode

I have the T400 with Windows XP (32bit). Dual P8600 2.4GHz processors & 3GB memory. Fairly new computer so there is plenty of space.
I run a macro out of Excel every day. When I run the program it takes about 15 to 20 mins and Excel struggles to move. This is normal with this laptop and it is annoying. I found that there have been times when the program runs fast as it should - fast as in 4 minutes. Processing speed is clearly faster but all programs are the same. I have also come to realize today that it runs faster after it comes out of Standby Mode. If I shut down and then re-start the computer and then run the program out of Excel it takes 20 minutes. If I start up, then go to standby then come out and run the program it runs in 4 minutes.
What would cause this? Is there some background process that stops after Standby that would allow the processors to perform as they should?
Thanks

is your CPU throttling down. Download HWinfo32 and check the cpu speed when the excel is running slow (the 20 minutes).
also are you running the laptop with the battery inserted? and do you have the latest thinkvantage power manager installed? what version of the bios firmware are you running?

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.

Mega 865 Fan Control after standby

Hi,
With the Mega 865 Bios in S3 mode, I am noticing that when XP SP1 resumes from Standby or Hibernate mode the fan stays on full power. Is anyone else noticing such a problem?

it would appear to be from the other thread i have read.

Satellite C850 - Low fan speed after BIOS update

Hello,
So I have my Satellite C850-PSKCEV bios updated around 6 months ago to version 6.80 (I bought my laptop in 2012), and since then the fan is running at low speeds and will never run full speed as before, and as a consequence the laptop overheats prematurely and very fast, and even when the laptop is not in use but left running it does overheat, also gaming is not even possible as any game that I run (even with the lowest settings) gets a fps drop every 5 seconds and lasts 5-10 seconds which renders even the lightest games unplayable, also I am afraid of the continuous overheat to damage the laptop's internal components.
I did clean the fan and vents from dust and there is not even one particle inside them and yet the fan won't run fast and I can't feel but very slight airflow from the vents as apposed to the strong one before this problem.

Increased fan speed after Leopard install

Hey - Just installed leopard today on my intel core 2 duo blackbook, and I have noticed that where under no processor load my fans would run at about 1800 RPM. Now, it has been consistently at about 2600. I have reset the SMC (I think that's what it's called, the PMU on PowerPC systems) and updated to 10.5.1. Has anyone else experienced this??
Thanks,
Dave

CPU temperature increases considerably as well as fan speed after upgrading to 10.7.4

I'm running an 8,1 MacBook Pro and just upgraded to 10.7.4. While idle, my CPU temperature now stands at around 180 degrees Fahrenheit and my fan runs at 4000+ rpm. Is anyone else having these issues? How should I try to fix?

E31 - Front FAN at full speed after bios update !!

Hello,
we have a Thinkstation E31 (2555-22G), and today after the Bios update with the Lenovo system update tool the front Fan (near the SATA connectors) is at full speed constantly. it is just impossible to stay in front of this computer because of the noise, i had to disconnect the fan.
I tried to flash to an older version available on the site but it doesn't change anything.
I tried to reset the BIOS to default, and also removed the battery from the motherboard.
I found in a faq but for another model to remove the power cable and press the start button during 10 seconds.
I didn't find something working, there is no fan control setting in the bios, or it is well hidden...
What can i do ??
Thanks for your help.

The beeps you're hearing are part of the CMOS clear process, so they are normal. Once you hear the beeps, you should be OK to shut it down again.
I'm not necessarily convinced a bad fan is the cause of the issue if you truly only experienced the higher fan speed after a BIOS update. But I also don't want to work on the same issue from two angles/paths at the same time....so I'm going to say let's wait and see what happens with the service route first and go from there.
If you happen to try it again or see the message again...I'm curious what error codes you're seeing after the system starts and you get the two POST beeps. A message about corrupted settings sounds like it could be important A picture might be helpful here if you can capture one.

Mac pro 3,1 default fan speed?

Hey guys, ive been messing around with SMC fan Controller over the years, and have increased minimum fan speeds due to hotter ambient room temps, or simply because i was running extended cpu intensive activities. Good to take precaution since the 3,1s are known for increasing fan speed after things have already gotten too hot. This can lead to overheating. At some point within the SMC fan Controller app, i changed the "default" fan choice higher instead of creating a new blank custom fan setting before choosing my fan speeds. My problem now is that i dont know what the default settings were. i think one was 500, 600, 600, 800 RPM maybe? No idea.
its is a 8 core 3.2 earl 2008 3,1 Mac Pro Desktop. This has different fans than all other mac pros so this question is 3,1 specific.
I think the four fans are labeled:
Power supply
I/O
CPU
Intake
not entirely sure because i am away from teh computer at the moment.
Thanks
-Mitch

smcFanControl's preferences are located in /Users/<user>/Library/Preferences as com.eidac.smcFanControl2.plist. I believe that if you move that to the desktop and restart, a default plist will be rebuilt for your particular Mac. If that doesn't fix it, you can always put the plist back where it was.
Or, you can simply make smcFanControl not a startup item and then use something like iStatPro to see what the unadjusted fan speeds are because smcFanControl doesn't change the built-in speed defaults, it just overrides them as the lowest fan speeds.

GTX 670 PE OC - need BIOS with reduced dust removal fan speed

Hi,
I'm looking for someone who will be pleased to reduce or stop dust removal fan speed after restart.
Would like to modify latest BIOS with UEFI support.
There was a BIOS which was removed from German MSI site.
I can provide it if necessary.
I'm willing to give some reward for the effort.
Thanks.

Flashed and now much quieter at boot.
Many thanks for your help Svet, you guys are amazing.

[solved] fancontrol - fan speed doesn't seem to change after boot

I used fancontrol to control my fan but after I rebooted it doesn't seem to speed up the fan when it hits MAXTEMP whereas it did before I rebooted.
Before the boot I set the CPU governer to performance (3.1Ghz) to heat up the cpu to test the fan cooling (using lm_sensors) and when it hit around 65c the fan got faster and cooled it adequately but after reboot the temp has gone right up to 90c and the fan doesn't even sound like it has sped up.
I have the AMD 8120fx 8 core CPU which is set to default/stock clocks in bios.

Thank you for your response. I did have the lm_sensors.service problem before but not when I had this problem (I solved that by adding the modules created by sensors_detect to a module-load.d file.)
The problem (I think) came from trying to fix the boot-to-boot inconsistencies (caused by lm_sensors.service). What I did was blacklist my k10temp module and that stopped a device from being detected. Then, when I generated the configuration file it didn't add the device.
Below is my new configuration file, where you can see the device(hwmon1) is now in it.

Fan speed up after 10.4.3 update

Today, I applied the 10.4.3 combo update to my iMac. After reboot, the fan came on full speed, and has stayed there ever since. I tried an archive and install of 10.4, and applied all updates. I also tried reseting PRAM, as well as the Open Firmware resets. No joy. The fan is still full blast. Any ideas or suggestions? I'm stumped.

it's all right here:
http://docs.info.apple.com/article.html?artnum=301733
it says in there that the SMUs control fan speeds. I hope that fixes it for you

IMac fan speed increased after upgrading hdd.

iMac mid 2010 i3, I replaced stock hdd to a two terabyte western digital caviar green. After replacing the fan speed rapidly increased. I installed smc and still no resolution.

FIXED THE ISSUE.... This took a little time, but it was a simple fix. The LCD sensor that you have to disconnect from before removing the LCD was the issue. After receiving HIGH CPU fan speeds, I began looking at possible issues. First, I had [http://www.macupdate.com/app/mac/12381/temperature-monitor|Temperature Monitor] Installed. I had all my sensors including the ambient air sensor reading. After I upgraded my HD to a SSD I started getting HIGH CPU fan speeds, but the HD and DVD fan speeds were fine. I looked at my Temperature Monitor and I noticed i had several Temperature Monitors not reading including the ambient Air Temperature (bare with me, these are steps to troubleshoot). After reseting the SMC and PRAM, still nothing. I shut down and disassembled my IMAC again. This time after i removed the LCD, I looked at the LCD cable that you must disconnect when removing the LCD and BAM, I saw the issue. The wires that connect to the Motherboard from the LCD Sensor, inherently like to lay across the screw hole the Bezel attaches to. I have a couple of pinched marked that exposed the wires and when I tighten the bezel down, it shorted the wires and caused the issue. I cut small pieces of electrical tape and covered the bare spots. When I reassembled the IMAC, i made sure that all my BEZEL screw holes were completely clear of any wires. Once back together, I plugged in the IMAC, waited 5 Seconds and turned it on. All is well. I feel this a majority of everyones issues when they take apart their IMACS and put them back together. THe Fan Control SOftware is good, but this was my solution that worked. Hope this helps.

CPU fan running full speed after 15 minutes

My 3 month old iMac 24" has just started having fan problems.
Before I went away on a training course, it was working fine. Left it switched off at the outlet for 3 days, now the CPU fan runs full speed after the iMac has been switched on for 15 to 20 minutes.
CPU temp is 24C, CPU heatsink is 28C. Ambient is 17C. CPU fan is 3600rpm. Other fans are normal.
CPU usage is less that 10%. Only Safari is running.
I've tried resetting the SMC - left all plugs disconnected for 15 minutes, reconnected mains power for 15 minutes, reconnected USB, then switched on.
Still the same - OK for 15 minutes, then CPU fan runs full speed.
Anything else that I can try?

I tried again, following your instructions exactly. It seemed to work, running normally for about an hour.
I left all the USB devices unplugged, except for the keyboard and mouse.
I then shut the iMac down, but left the mains power turned on at the wall. When I switched it on again 2 hours later, all was OK for 15 minutes, then the CPU fan ran at full speed.
Shutting down for a few seconds fixes it for another 15 minutes.
I'm wondering if it's a software problem, although I haven't loaded any apps recently, apart from a few monitoring programs since this problem appeared.
Last night I left it running the extended hardware test for a couple of hours, and the fans were fine.
One thing that I noticed yesterday was that the "GPU" temperature readings in iStat were all missing (just "-" displayed) for a couple of seconds when I clicked on Dashboard. Is there a way to keep iStat open while I'm using the iMac?
I think I'll try booting XP and see what happens.
