Fan/Temperature Problems

Ever since I installed Archlinux (about a month now), the fan has been going crazy. I did a little searching on the forums here, and I installed the CPU Frequency Scaling (http://wiki.archlinux.org/index.php/Speedstep) and that calmed it down somewhat, but now I am afraid of turning down the fan if there really is a need for it. Which program will tell me the temp of the CPU? I have seen references to something called Conky, but thats it.

Do you have xf86-video-ati installed? You fan keeps running might be caused by these open source drivers. In my box, fan keeps running when using radeon/radeonhd driver. Using fglrx doesn't have this problem.

Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help

Please HELP, I have a fan speed problem with my Power Mac G5 Dual 1.8 GHz PowerPC
This is a NOT an Intel machine. I am running Mac OS X v10.5.8
Power Mac G5 - PowerMac 7,2 - Power PC 970 (2.2) - 1.8 GHz with 2 CPUs - L2 Cache (per CPU) 512 KB - Memory 8 GB - Bus Speed 900 MHz - Boot ROM version 5.1.5b1
I have included below Links to download a sound file (.m4a) that I recorded of the fan speed problem and both a .pdf and .spx files of my system profile.

When did the fan problem start?
After I replaced the mother board on the computer.
Why did I replace the mother board?
Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500

Power Mac G5 (Late 2004)
To reset the SMU on a Power Mac G5 (Late 2004) computer, simply do the following:
• Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
• Remove the power cord from the computer.
• Wait two minutes.
• Plug in the power cord.
• Turn on the computer.
7) followed the SMU reset instructions:
Resetting the Cuda/PMU
How to reset the PMU:
• If the computer is on, turn it off.
• Disconnect ALL cables from the computer, including peripherals and power.
• If possible, move the computer to a place where you are not standing on carpet.
• Open the case and ground yourself by touching part of the metal frame inside the computer.
• Find the Cuda or PMU button
• Press the Cuda or PMU button ONCE. Do not press the button more than once before starting the computer up again.
• Wait 10 seconds, then reconnect the cables you removed in step 2 and turn the computer on.
• If the computer still does not respond after resetting the PMU, the computer may require service from an Apple Authorized Service Provider.
8) ran disk utilities, repaired permissions
9) found a setting in the system preferences that a chat room person suggested had something to do with fan speed. In Energy Saver, under options, processor performance was set to highest, I set it to automatic - this did not change anything that I could tell - BTW I checked my other G5 (a single processor that works fine) that is the setting that that it is set to, and it is nice and quiet.
10) restarted the machine, ..
11) found a Fan Control System Update - but it did not install when I tryed to install it -
12) booted from OSX install disk and ran that disk utility
13) used OnyX to fix disk permissions, clear caches and temp items
Nope - still have the same high speed fan problem. ... PLEASE HELP!!
I have been reading in the MacInTouch reader reports - found this: some one said to use this - thermal re-calibration using the Apple Authorized Service Providers' disk - but that's not available, at least I can not find it - anyone? have an answer to finding this - or can do it for me? I am in Chicago.

The Genius at the downtown apple store said that because it's a "legacy machine" they would not work on it, .. so should I push them?
Well, I personally think that's ridiculous, I'd Push them, I'd call AppleCare & talk up the chain if need be... there the ones that have or should have that Disc... man o man... Personally I'll never visit an Apple Store again in my lifetime, maybe try an independent AASP if none of that helps!..

MacbookPro 13'' temperature problem

Hi everyone, I have a Macbook Pro 13'' Mid-2012 (A1278) with a Intel Core i7 2.9GHz for a year ago, but the cpu fan is a little noisy and I check temperature with a "Temperature Monitor App" and CPU Temp is 80ºC with only Chrome and Coda 2 opened.
Normally I work on 3D applications like Autodesk Maya and AutoCAD, this apps can overheat the cpu but now i can't work with these apps because the performance is very low, I cleaned up the logic board and temperature don't decrease.
¿How can I decrease CPU Temp? I bought a new CPU Fan and I don't want it damage again...
Thanks for help me and sorry for my english I speak spanish

And the magsafe connector is so hot like 100ºC but charge the battery and works fine but is hot. I have 2 chargers one 65W (original) and another 95W from another macbook and both have the same temperature problem.
100°c on the charger body is unacceptable and would be impossible to touch for more than a second. Mine have never been more than 55°c. There is something terribly wrong here. Look at the contacts between the charger and the MBP. Is there any discoloration? the pins in the charger connection are spring loaded, do they move easily?
Fan Speed is 6140 rpm and CPU temp is 75ºC, I think a change the thermal compound.
The CPU temperature is not bad nor is the fan speed. I have doubts about that replacing the thermal paste will improve thew situation.
Open the MBP and see if there is dust an debris inside. I f so clean it out.
Again, delete Google Chrome and see what happens. It has been known to have compatibility problems with OSX.

[SOLVED] Notebook temperature problem

Hi everyone,
I use Arch Linux (i686) since 2008 on different machines. But my Acer 8935G Notebook is giving me headaches for some time now.
I bought it one year ago and Arch Linux ran nearly out of the box (ALSA drivers took some time, but that's done). In spring I noticed, that the computer is getting hotter than it did before (Idle: 70° Celsius / 158° Fahrenheit). In Windows Vista, I get idle temperatures around 40° C (104° F). And before spring, I got temps booting Linux around 50° C (122° F), which was absolutley okay and worked for me.
I didn't change system settings or configurations, and I tried some possible solutions, because I thought, maybe it's a kernel problem, but that's just a wild guess.
What I did so far:
- trying alternate kernels (BFS, CK, ZEN)
- tried different cpufreq settings (dynamic cpu scaling is working -> cpufreq-info)
- undervolting via intel-phc (no changes in temperature at all)
- tried powertop
none of that worked.
I have to say, that's not just a Arch Linux-related problem, other distributions give me the same problems (PCLinuxOS 2010, Linux Mint KDE 4.4).
My question so far is - has anybody experienced similar problems and found a solution for it?
Thanks in advance for the help - I'll really appreciate it.

Thanks TigTex,
but I can safely say, the temperature problem is real. It's not just a false sensor, because of the heat, the metal-case of the laptop is generating. It really gets uncomfortable when working on that hot case (hands on the hot machine and typing - after a while you can order your hands "well done" *sigh*). Because of that, I switched to an external keyboard, but that's not really a solution. The weird thing is, that the temperature problem didn't exist at the beginning - and it doesn't exist on Windows. And it's also not a cleaning problem - I clean my machine regularly (because I hate dust, generally ).
I can also say, that the fan is working - and it's working also dynamicaly (gets louder, when the machine gets hotter).
I checked the CPU sensors on Windows with Core Temp regularly (runs automatically in system tray at boot).
The machine ran 20 minutes (after 1h I get around 70° C / 73° C / 73° C):

MEGA 865 fan control problems after suspend/hibernate.

I'm seeing the CPU fan control problems, and it's REALLY ANNOYING, as it means I have to leave the machine on all the time. Specifically, after suspending or hibernating the machine, on wakeup the CPU fan goes to full speed and STAYS THERE until I reboot.
This is on a CLEAN INSTALL of Windows XP.
Is there going to be a fix for this from MSI soon? Because it's really ruining the experience of using the MEGA.

Hi guys,
I have builded a Mega 651 attaching a Celeron 2.4 Ghz.
I installed the cooler but I got really scared when I realised that the fan run for 2 secs and then stopped.
Is this normal?
If yes then i am assuming that the voltage of the fan is controlled by a thermal sensor, meaning that the fan goes on when the temperature reaches a certain limit.
Can the threshold temperature be controlled from bios so I can set it to minimum possible?
thanks in advance

K7N2 Temperature Problems

I'm having some small temperature problems with this board.
Here are the temps
CPU: 45-60 (normal-load)'c
Case: 38-45
Chipset: 42-47
The CPU isn't too bad, although I do see some strage fluctuations, like while writing this, its went upto 57 and then the next reading dropped to 47???
I have a laser digital thermometor which obviously can only scan temps external of the heatsinks, but it is accurate, and it does report similar temps.
My main worry here is the case temperature.
Here is my setup
K7N2 Delta 2
athlon 2.5 @ 2.2Ghz
1GB corsair (512*2)
Nvidia 6800GT 256MB DDR3
DVDRW
DVDROM/CDRW
120GB SATA HDD
500WATT PSU (which is heating up a little and could be a cause of this)
3 case fans
thermaltake volcano 12+
I've tried not clocking but there is little difference, room temps are at 20-25'c.
The heatsinks near the chipset seems to be getting rather hot also.
It doesn't have any stability problems. Its fine with games, no slowdowns. but its just the temps.
Can someone please compare my temps with the same board, just so I can get an idea.
Thanks in advance

I definitally need something black...
Otherwise it'd be a little out of place!
In all honesty I wish I could buy things from newegss. they seem to have a great range and nice system.

Its way out of my price range. I have £50ish set aside for it, and I'm looking at these at the moment all from overclockers (seem to have best range, not price) :

915gm-fr temperature problem

Hi! I´ve got a temperature problem, I just installed the Arctic Cooling freezer 7 cpu fan, to hopefully reduce the sound. But not!!! The fan runs at 2700rpm during cpu workload at 1% in windows, the bios is configurated to use temperature control. And the cpu temp in core center is 48 (pendle sometimes between 43- 60). I´ve tried some settings in core center but I think that program is crap.
The freezer 7 is icq cold. I want it to run in 1400rpm or less ( And I don´t think that is impossible), how can I control that? Or what is wrong?
Becouse the freezer 7 is ice cold there is no need for the fan to run at that speed. Maybe something is wrong with the PWM from the motherboard?
I think I´ve got a problem with the temperature control on the motherboard, reading wrong.
Best regards

I´ve got
915gm-fr motherboard
Intel P4 s775 3,0GHz HT
windows xp
BIOS version 1,6 (newest) and newest core-center
the cpufan is running at 2700+ rpm doing idle. !! =( and the cpu is around 50C
must be something wrong with the cpu temperature sensor?
I´ve never seen the fan speed slower, just full speed, even with the boxed cooler too.

Ipad 2 temperature problem since I have it

In January 2014 I exchanged my former ipad 2 to a new one using the out of warranty option. This new ipad 2 supposed to be a new one but it never worked because since the beginning I had this temperature problem that avoid me to use it for more than 5 minutes.
What can I do. Is this new ipad on warranty even I bought it using the OW? I paid $ 249+ tax!
Thanks for your help!

When you use the out of warranty option your replacement iPad does have a warranty just not as long as a new one. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

An EMU temperature problem occurred

Hello,
The error message I get is: "An EMU temperature problem occurred"
My Xserve RAID has been given me this error three times in the last month, always early in the morning. There is no temperature fluctuation in the server room as far as I can tell. The raid works fine and orange warning light comes on with no alarm. The raid admin initially reports failure, but when I click on the button it goes to green.
Is this a symptom that my controller is starting to fail? I cannot find anything on the web about this topic!

It wouldn't hurt to monitor the climate in the datacenter. We are using the weathergoose products:
http://www.itwatchdogs.com/
These will track temperature, humidity as well as sound and light levels, and airflow. You could also add probes that will monitor house power so you could see how long the systems have been running from UPS.
You could also download the SNMP MIB to be used with a third party graphing utility, such as Cacti.
These products have helped us to keep track of the cooling and overall health of our servers.

Custom Hardware Fan Control - problem if speed pin not connected?

Hi There,
I am planing to install a hardware fan control (poti) to my MacPro 1.1 rear fan. (because I have a defective northbridge temperature sensor and the fan is running at maximum speed... so i thought of slowing it down with a fan control for the pci slots)
I read that the pinning of the Fan is: Gnd, 12V, Speed, Control Pin (analog Voltage)
So when i would attach a fan control (just a poti) between some +5v and the Control Pin I think I should be able to control the fan manualy - am i right?
But then the speed signal is not the speed the mac pro fan control software think of... so would it be a problem e.g. if i disconnect the speed pin from the mainboard fan connector?
what would happen then? is the mac pro powering up the other fans for some kind of failsafe?
Or have you other suggestions how I can lower the speed of the rear fan manually?
thanks in advance,
Stefan

4 fans, 3 under the control of SMCFAnControl utility. Maybe disable the one fan and make up for it with your own fan and running the others efficiently.
There are also VGA copper coolers.
FBDIMMs bleed heat: maybe the RAM fan cooler kit in there to deal with large source of heat. New higher density DIMMs are better made and few DIMMs = less heat even if 4GB.
Use ice packs, dry ice and liquid nitrogen to super cool :-)

MSI HD 7850 1GB GDDR5 OC edition Fan speed problem

Hello all.
I have some strange issue with my graphic card and fan i think. I have noticed that, when my monitor goes to sleep (or when I manually turn off), after few minutes (7-8-9-10) I can loudly hear GPU fan acceleration. And it happens every few minutes. So, everything is ok few minutes, and after that, again I can hear that annoying sound, the sound of accelerated fan. That happens only, but only when the monitor is switched off (whether it manually or automatically switched off).
I bought this video just 2 months ago, as well as other components of the computer. So, everything is practically new.
I have tested my graphic card with MSI Kombustor v. 2.4, and everything was fine. Temperatures, FPS, and all that stuf was fine.
I've never had a problem in any game so far. Everything working fine on high details all kind of games. Temperatures are pretty
normal. In a fact, I think that is temperature is lower than some average. I have a problem only with horizontal lines, but that is because i have monitor with VGA output. As a mather of fact, barely notice them. And, I have instaled latest 13.4 drivers. I deleted the old version with driver sweeper. And in an earlier version of driver was the same problem...
Again, the problem arises when my monitor is off. I have tested with MSI Afterburner 2.2.5 beta and GPU-Z 0.7.0.
All settings in both of programs are on default. So, that numbers at paragraph RMP, when monitor is off, max is 1563. That is 400 more than when monitor is on.
I have tried to test when is minimum usage of GPU fan is 40% (i just clicked on "user define" button on the right side of "fan speed"), and then, RMP number would be 1700 or even more.
When monitor is off:
When monitor is on:
So, everything is perfect when monitor is on, again. I don't think that is normal, and I beg for help. Is there any kind of solution to fix this problem? Please. I am thankful in advance. Sorry for my bad English.
P.S.
I wanted to upload pictures, but forum does not allow me. Or, I don't know how to do that. I only want to show values...

Usualy, i left Opera, uTorrent, Skype in backround. Then, I shut down the programs, and only programs in background are Avast 8 and Realtek Audio Manager (both are in system tray). No matter if you leave a program in the background or not, it's the same.
I really have never met with this type of problem and I have no idea how to fix that. If I complain to the seller, he would run tests like I did, and everything would be ok. And when I would told him about the fan problem, probably would have told me that everything is okay...
I don't know what to try, really...

MBP 15' randomly shuts down: temperature problem?

Hallo,
I'm having a very serious problem with my MBP unibody (rev B). After a few minute of intense use (3D gaming or just streaming of HD flash video) it shuts down without any warning or alert. The event doesn't show up in the system log and it happens more often while using the 9600GT gpu.
It looks like a temperature managing problem, but the strange thing is that at the restart right after the sudden shut down the temperatures are absolutely normal and the fans seem to work as they should.
What could be the issue?
Moreover, I need my mac to work and I really can't afford to stay a day or more without it because it's in repair. It's still under official Apple warranty, am I eligible for an immediate full replacement?
thanks

Welcome to Apple Discussions
If it was shutting down due to over heating then you'd get some warning like the fans running at maximum revs for a while first ...
Are you saying the Console (All Messages) Log is not showing anything at all at the time of this event ??
It's probably best you contact the place where you bought it and have them take a look, there's nothing anyone can do here about hardware issues. It's highly unlikely you'd be given a replacement but any repairs needed would be covered by your Warranty.
