Fan runs (nearly) fullspeed ALWAYS - XPS l502x

Hey!
After trying everything i end up really desperate and now count on your help.
Following is my Problem:
I changed my HDD for an SSD two days ago after having my XPS L502x for nearly three years now.
Everything works fine with the SSD, it runs super fast, i installed Windows 8.1 (before that i had 7). So i didn´t clone my old one, just started over with the SSD.
Now my fan (blowing out on the left side) runs always without any breaks at constantly about 90% power. It begins just the moment i start the laptop, so already before the dell-logo and without even booting Windows.
Here is what i already tried without any change of fan activity:
- installing all kinds of drivers, from Dell, for my Nvidia, every single one i found for the parts of my laptop (also removing and installing graphic drivers)
- booting Ubuntu from a DVD
- updating to the newest BIOS, downgrading to an older one, trying a few settings in the BIOS
- using different diagnostic tools from Dell (as well speed fan), all in the end telling me they can´t access the fan
- dis- and enable TRIM
- changing to my old Seagate HDD (to check whether i might have damaged some temperature sensor from the fan when i disassembled the laptop partly to reach the HDD), and here comes something interesting: the first time i changed back to the old HDD the fan worked just well again, totally normal with spikes when getting hot, but most of the time silent. Then i changed the original HDD (suspecting it might have some kind of temperature sensor or other thing to communicate with the fan) for another HDD from HGST, which made the fan go crazy again. Changing back to the SSD it didn´t work as well, but then i tried the original again to look for software and suddenly it didn´t even work with that one anymore...
So it could be, that i damaged somehow something of the fan when changing the hard disk, but i can´t really believe that, having in mind that building in the original hard disk again for the first time made the fan work normally. I´m believing it has to do something with the software, though i have no more ideas what it could be.
My System:
The old HDD is a Seagate 750GB Momentus.
The unknown device is the ST Microelectronics DE351DL Motion Sensor, Windows 8 just doesn´t support the drivers given.
BIOS right now is the A12 (i did the downgrade with A6)
If you need anymore information just let me know.
I´m happy about any advice, guess and help you guys have for me!
Greetings
Lukas
PS: Also, if you don´t understand something because of my English ask me or talk German to me :)

Hi Anamandy,
There are no settings in BIOS that can be changed to control the functionality of the fan. However, there are couple of options you could try within windows.
Go to control panel -> power options -> change plan settings -> change advanced power settings -> processor power management -> system cooling policy -> on battery and plugged in -> change to passive and apply. Check this link for more info - http://bit.ly/1OPjs9m
You could also download and run Speedfan - http://www.almico.com/sfdownload.php- however this application does not detect the fans on all system models.
You could also change the optimus settings to auto in nvidia control panel - http://bit.ly/1Gg5CYU- you could do this if you do not use the system for gaming / high end graphical usage.
My suggestion is to clean the air vents and if you are able to open up the system, then clean the fan blades. This ideally might fix the issue.
If the system is under warranty, then please send me the service tag of the system and your contact details through a private conversation. Or you could use twitter - @dellcarespro
- we can DM through twitter and help you fix the issue.
Keep us updated.

IMac G5 (no iSight) fans running full speed always

Hi,
The processor usage is relatively low (like 10%) but the fans are full speed at all times from the second the power comes on. I imagine there isa problem with the mother board? I've tried resetting all the SMC stuff, no effect.
Any ideas?
Is this something Apple Stores will charge to fix?
Thanks

It could be either faulty, leaking caps, or a failing power supply unit. Yes, Apple will charge since you are long out of warranty. You can open the machine and check the caps yourself, they look like little soda cans, and their tops should be perfectly flat and there should be no exudate.
Let us know what you find,

2010 MacBook White is unstable, fan runs all the time and wifi adapter randomly quits

I have a 2010 white MacBook running OSX 10.8.2 and last week rather randomly it became unstable. The fan runs nearly constantly and intermittently it does not recognize the WiFi adpater on start-up and has to be rebooted. Also sometimes after 15-20 minutes of use internet connection is lost. The WiFi adpater is still connected to the LAN, and recognizes other devices on my network, but cannot connect to any local device or the internet (Mail, Safari, or Chrome).
Any ideas?

This sort of helped.   Here is what happened:
     Upon the first boot after resetting the SMC, the MacBook indicated there was "no WiFi hardware installed."
     Shut down the MacBook and waited 15 seconds then started - it recognized the WiFi hardware and indicated a connection to my local network, however none of the local devices could be found and the internet was not connected.
     Restarted the MacBook to the same results as the previuos shut down/start up.
     Shut down the MacBook and waited for 15-30 seconds. Upon pressing the power button only the indicator LED on the lower right side of the body illuminated solid and nothing else happened.
     I had to then press and hold the power button for 3-5 seconds for the LED to go out.
     I pressed the power button and the MacBook started (very slowly). I gave it a few moments after the desktop appeared and the bars appropriately populated (WiFi indicator on the top bar looking good). Internet and local devices connected and no fan . . . yet.
My confidence is low, it's only be about 5 minutes, but will post again with an update . . .

Ibook want start - only the fan runs full speed

Hello to all,
my problem, when i start the ibook only the fan runs in fullspeed, thats it.
to shut down the ibook i have to remove power and accu, the powerswitch do nothing.
pmu and nvram reset does´nt help. the first problem was that date/time will lost, than after view days he does not start. is the problem the Backup battery? And how to change?
thanks to all for help

Hallo Wein and welcome to Apple Discussions ,
my problem, when i start the ibook only the fan runs in fullspeed, thats it.
to shut down the ibook i have to remove power and accu, the powerswitch do nothing.
pmu and nvram reset does´nt help.
Well try this and see if it helps:
http://www.coreyarnold.org/ibook/
If so it's U28 on the bottom of the board. The shim fix will work for a good time but a permanent repair is to have the chip resoldered. $40 at Superior.
the first problem was that date/time will lost,
That's because the power is interuppted.
is the problem the Backup battery? And how to change?
There is no backup battery or PRAM battery like in the PowerBooks. There is a .22 Farad super capacitor that will hold settings for a while but not long. Meant to allow a battery change.

Windows Movie Maker can't start. Dell XPS L502X running 64 bit Windows 7
Used to work fine until we updated MS licence. Seems to be a problem with graphics driver, yet I've tried all the posted fixes with no luck.

Hi,
Due to Windows Movie Maker is an additional application, you can reinstall it for repair.

Ram upgrade to 2GB - fan running faster

I have just upgraded my intel mac mini from 512 MB to 2 GB using a kingston upgrade kit (KTA-MB667K2/2G).
The system is performing a lot better but there is an annoying "trouble": when 2 GB are installed the fan is running more fast and more often then with 512MB.
During my tests, I have see that while using OS X the system is able to regulate the speed, it goes from very slow to very fast but it moves to fast more often then before and the system is definetly making more noise.
The bigger problem happens when booting using windows XP: when 2 GB of RAM are installed the fan is always running at top speed or near to top speed.
That is not happening while using the original 512 MB.
I have tried to reset the SMC by using the apple istructions here:
http://docs.info.apple.com/article.html?artnum=303446
but it didn't make any difference.
I have double checked all wires,I have switched from 512MB to 2 GB and from 2 GB to 512MB three times(!) but nothing has changed:
- when using 512MB fan runs slow;
- when using 2 GB fan is still able to change speed but is running fast more often.
Further more, to test, I have also left disconnected the fan speed cable in the front side, and in such way the fun starts at max speed and runs at fast speed all the time. So it is not a trouble with such connection.
Is that normal this behavior?
Does anybody have noticed any fan speed difference after RAM upgrade?
About BootCamp and XP running fan at max speed, could be that reinstall them could solve the "always on" fan trouble with 2 GB?
Thanks a lot for any help.

I have some updates about the problem.
I was thinking that it was a my fault about some missing setup needed when installing more ram to mac mini.
So, today, I have moved to a local apple center and I have asked them to install the RAM for me... they do, and it happens the same thing: the fun was running very fast quite often under OS X and was always fast under bootcamp-XP.
I have asked them why this happens and if that was normal, but they have no other mac mini with such amount of ram and they never see it before. They suggest me to test it for a week and eventually to give them the mac for a day to make some hardware tests.
Later, back into my office, the noise was too high and too annoying so I have called again apple to explain the situation.
They told me that they have no reports about similar problems, that it should not make more noise when adding RAM. They suggest me to try remove and reinstall better the RAMs or to try different RAMs (I am using kingston kit KTA-MB667K2/2G).
So I have also phoned to kingston support, and they say that it is a strange bahavior, that they don't have reports about that too. They are now investigating the problem and they let me know something in next days.
They also put to my attention the fact that the computer is able to see and work well with the 2GB memory, so the memory is working correctly. They think this is something related to apple hardware/firmware and could be that apple should fix it in next realases.
Unfortunatly, all this new infos and all the time lost for a "simple" memory upgrade didn't solve my troubles and I still cannot use the mac like I need.
So I have continued my tests by changing the kensington Dimms with other 2 GB dimms by Nanya technologies that were installed on my centrino duo notebook.
Mac mini was able to see and work well with them too, now the fun speed is a little bit slowly then using kingston ones but still more fast than with 512MB.
Bootcamp-XP is still not usable due to high fan speed and the high noise. OS X seems to control better the fan speed but it goes high there too for any little thing you do.
So I have made one more test suggested by kingston:
I have started mac mini while only one kingston dimm were inside.
In this way the mac mini was making some less noise that using the two nanya dimms, but it was still to high.
The last test I made was to check the cpu temperature with different amounts of RAM and results were interesting.
Using OS X with 512MB, the cpu temperature is about 33 C while iddle; if I try to start parallels desktop with guest windows XP, temperature goes up to 40 C and the fan is still running at quite low levels.
Instead, while 1 GB of RAM was installed, cpu iddle temperature was 35 C and starting parallels desktop will result in temperature levels till 50 C.
So there was a difference of about 10 C.
While doing these test I have left the mac mini open, so once stopped, I was able to quickly feel the RAM temperature with my finger and it was quite hot.
I didn't try temperature with both 2GB dimms, but I belive it will be surely more high.
So what I am thinking now is that probably apple is aware about higher temperature inside when using more RAM, so the bios starts the mac mini with the fun running faster because it detects the 2 GB memory.
OS X is able to control someway the fun so it is not always running fast (but quite often) while using boot camp with XP becomes impossible due to the fan always at max speed.
I don't think apple's rams could work at lower temperature than kingston ones, so the dubt now is that things are correct in this way.. so intel mac mini with 1/2GB could be a shame due to high level of fan noise... or... my mac mini has something wrong.
Is anybody here with a mac mini and 2 GB of RAM?
Anybody could make some test about that?
Thanks a lot for any help

HDX18 fan runs constantly after BIOS update

I updated my BIOS to the latest F.31 version before installing Windows 7 as recommended. Now my fan runs at the same speed all the time no matter what. Before this my fan ran very slowly at idle and blew like a hurricane when I was running games or the TV tuner. It changed with the conditions now is always the same.
I went into the BIOS and there is a setting for "fan always on" that I could change to disabled. I am comfortable in the BIOS but a little leery of making any changes as I am not an expert here. Anyone have this issue? Will disableing the fan always on make it variable again? I regularly blow out all my vents and the computer is very clean so I don't think it is a dust issue.
Dave

oh I see. One option is to supplement with an small external fan (these are cheap) near the laptop's air intake. I'm not sure if changing the BIOS setting would make it variable again, that's an interesting question. Regardless I would supplement with external fan to be on safe side in my humble opinion.

XPS L502X integrated webcam won't start, error message "Close the other video streaming applications to start video"

Hello, i've been working with this issue for more than a week now. Have tried all the solutions on the net without any success.
Windows 7 home premium x64 is installed on the machine.
When trying to use any application using camera shows up a message, that webcam is used by another application. This pops up on Skype and Dell Webcamcentral. Ms Silverlight shows black screen, no message. The device is present under imaging devices in device manager. The driver installed is Microsoft 6/21/2006 ver. 6.1.7601.18208, status "device is working properly". Driver files: ksthunk.sys, usbvideo.sys and ctclsflt.sys after installing webcam central.
Here is what i tried:
1. Installing drivers from Dell.com in the correct order
2. Uninstalling webcam driver and letting windows install the driver from windows update.
3. Uninstalling windows driver and installing Quanta webcam driver before restart. Note, that in all 3 steps quanta driver never showed up in driver details in device manager.
4. Uninstalled skype.
4.Uninstalled all "usb root" in device manager, restarted, windows installed it's drivers, installed Dell_SX2210-Monitor_Webcam SW RC1.1_ R230103.
5. Uninstalled Webcamcentral, downloaded and installed ver 6.1 Skype.
6. Started windows in a clean boot state.
7. Installed process observer. Webcam is used only by skype, but skype gives "camera used by another app" error message.
8. Turned off laptop, removed ac power and battery, pressed power on button for 30 secs.
9. Tried to update driver through device manager - driver is up to date.
10. Reinstalled windows and installed chipset drivers + wireless drivers and let the windows update. Then installed all Dells drivers in the correct order.
11. Restored to the point before windows update and installed Dell drivers in the correct order.
12. Restored to the point after windows update again. Installed ms Silverlight, camera shows black screen. Room is light, tried a sheet of white paper close to the camera.
13. Tried different skype versions again, uninstalled skype.
14. Process observer shows that nothing uses webcam. Supportassist shows failure in webcam at all checkup stages. Supportassist suggests to turn of programs that might be using camera.
15. Tried all the steps before windows reinstall.
16. I gave up and ask for your help.
Here is Supportassist diagnostics log:

Iqb,
Make a system restore point.
Start, control panel, device manager, Go to the USB Controller section and click the + sign. Go to each USB Root Hub. right click on it, left click uninstall.
Restart your computer. When you login, the new hardware wizard will reinstall everything. Please be patient, it could take up to 2 minutes.
Try the webcam and see if it works.
If no, then the webcam became detached from the motherboard, usually near the webcam

My MacBook Pro fan runs while sleeping

My MacBook Pro fan runs constantly, even while sleeping.
The problem started about 2-3 months ago, but was pretty rare. When I noticed the problem, I would restart the computer and it would stop for 1-2 weeks. More recently it has become more constant, and now it always has the fan running when it's sleeping.
Any ideas on what I should do? Thanks!

Mine too. If you're worried you might like to try a laptop cooler like one of these:
http://www.amazon.co.uk/s/ref=sr_kk_2?rh=i%3Aaps%2Ck%3Alaptop+cooling+pad&keywor ds=laptop+cooling+pad&ie=UTF8&qid=1344763538
Not sure how well they'd work on a Macbook as there aren't any vents on the underside but it couldn't hurt and they're quite cheep.

Fan running high, Windows Vista

I - finally - have Windows Vista Ultimate running properly on my MacBook Pro. But I notice that after I use it for about 10 minutes the fan starts to run high/fast.
And solution?
thanks - Otto.

Install InputRemapper. That will insure that the fans run at a minimum 1000 rpm to keep things cool and heat doesn't build up.
Install SpeedFan to monitor the thermal sensor temps - unfortunately it doesn't automatically control fans as it should.
Otherwise, seems like something is causing system to run hot, and for me, it always took hours before I saw that before I started using InputRemapper.

But I am not confident that there isn't more to this, like resetting the power or system management control unit or something.

MacBook Pro Fan running fast after Mavericks update

Hello All! I have a 2009 MacBook Pro 13 inch and I have noticed that after I updated to Mavericks my fan has been running really fast and my computer getting warmer than normal. It's always on a table so there is nothing blocking the port in the rear. Any ideas on how to fix this?

Hey emilyiow,
Thanks for the question. I understand that you are experiencing issues with your MacBook Pro in relation to the fans. Sometimes, this symptom can indicate that the SMC needs to be reset. For more information and instructions on how to do so, check out this resource:
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
http://support.apple.com/en-us/ht3964
After performing normal troubleshooting, these symptoms may indicate that an SMC reset could be necessary.
Fans
- The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
Additional information:

What to do if you get an error in AHT
Confirm that the power adapter is connected if you're using a Mac notebook.
Confirm that all external devices are disconnected from your computer.
Record any error code given so that you can give the information to a Mac Genius, Apple Authorized Service Provider, or Apple Technical Support Specialist.

Fan running all the time - 2011 21.5 inch i5 iMac

I purchased a new 2011 21.5-inch: 2.7GHz i5 on Friday just gone (2 days ago). All was going well with the new toy until this morning (Sunday).
Suddenly the CPU fan was running all the time and at full speed when the computer was not under any real load - very noisy.
I have reset the PRAM and SMC several times now. Within 30 seconds of each reboot the CPU fan reaches 4000 rpm and stays there.
When I run a hardware test I get the following error - Error 4SNS/1/C0000008:TS2p--124. This error is detected under both the quick and extended tests.
I do have to say that I am disappointed that 2 days out of the box it looks like I am return the iMac to the Authorised Reseller.
Can anyone confirm my understanding that:
a) the CPU fan running loud and hard (4000 rpm) when not under load is NOT normal
b) the Error code above relates to the logic board
c) next step is take it back to Apple or the authorized reseller from where it was purchased.
Cheers
Shaun

4SNS/1/C0000008:TS2P--124
When U install the SSD under the optical drive(OD), the air from the OD fan that was supposed to swing under the OD to exit on the uppper vent has no where to go and hence swings across and exits mostly through the vent on the other side near the camera whereon lies a Skin sensor, which blows away/damages tricking the iMac to believe that the CPU is hot and the CPU fan starts to run at full speed of 4000rpm and the Apple hardware shows error 4SNS/1/C0000008:TS2P--124.
This skin sensor will then need to be replaced.
The CPU Fan cannot be controlled by any software.
The only options available are:
1.Change the primary HDD with a SSD.This will result in the HDD fan running at a higher speed as the SSD does not have any moving parts.The HDD fan sensor gets to believe that the HDD is hot since it does not get inputs from the SSD.Once you change to SSD you can use software to control the HDD or the Optical fans.
2.Change the Optical Disk drive with a "SSD in a Optical Drive(OD) Caddy".This will result in the optical drive fan running at a higher speed as the SSD does not have any moving parts.The OD fan sensor gets to believe that the OD is hot since it does not get inputs from the SSD.Once you change to SSD you can use software to control the HDD or the Optical fans.
Do not use the OWC or other dual drive kit that advice U to put a next SSD under the OD, unless ur iMac is under warranty or u have plenty of technical skills & luck.

MacBook Pro fan running constantly with no utilization

Just got my boss's MacBook Pro (Retina, Mid 2012) model back from Apple after a GPU related repair (which appears resolved). They replaced logic board amongst other things.
As soon as I turn it on I hear the fan, quietly running. If I close the lid, it runs for about 20 seconds then stops. This is not loud; they are not running full blast (that is a much different sound). But I can hear it in a quiet room. Owner of the laptop was complaining about fan noise before; I assumed he was stressing the CPU but now I can see what he was complaining about.
Activity Monitor (with 'All Processes' selected), sorted by CPU, shows nothing running more than 1-2%, and 'Idle' at the bottom is showing about 99.65%. So there are no runaway processes. The room (ambient temp) is about 66F (not overly hot). The laptop is on a tile counter - no obstacles to airflow. Same issue occurs on battery and wall power. Over a several hour period, I never hear the fan stop.
I did an SMC reset (ctrl-opt-shift-Power) and this seems to have no effect (this seems to be the magic bullet for most of these issues, after tracking down runaway processes).
So my question is - does anyone know what the design is - could it be that the fans are designed to run all the time on this model, but they are (supposed to be) super quiet and not audible at low RPM, and maybe these fans have been become noisy, therefore I'm hearing it? Was this a specific design issue for this model of MacBook pro (with NVidia GPU)?

Update. I downloaded a nice free program called "Macs Fan Control" from MacUpdate. It shows me that I have two fans "Left Side" and "Right Side" and they are both running at the minimum RPM; the window shows Min RPMs as 2160 and 2000 (left/right), and the 'current' is 2161/2005 (changes all the time but very close to the minimum). Max RPM shows 5940/5499 (left/right). "Control" is auto, meaning the program is not trying to control the speed.
I tried setting the minimum below the values above (eg, I tried changing the minimum to 1,500) but it would not let me. I tried setting the minimums above the values shown, and it allowed me. There is obviously a 'safety' feature in the fan program to prevent slowing down the fans to a value below what is considered safe.
I then installed the same program on my MacBook air. I cannot hear any fan on my MacBook air, but - Macs Fan Control shows a single 'Exhaust' fan running at minimum value of 1200. If I press my ear hard against the bottom of the MacBook air, I can just about hear a faint, faint noise.
So my theory now is - the fans are always running on every MacBook (Air, Pro, etc) - the issue is, how fast they run. And, it would appear (from my MacBook Air experience) that the fans are generally quiet.
I then used the program to speed up the left side fan; the noise grew significantly and was unpleasant. At 4,000 RPM it was a deep, throaty sound. I then slowed it back down, and did the same to the right side fan; at 4,000 RPM it was a gentle 'whoosh' sound. SO ... this tells me the left side fan is messed up (bad bearings, etc). I PRESUME the two fans are the same, and should sound 'similar'. Would others agree with my assessment?

Fan Runs Constantly

Recently defected from Windoze and bought myself a iMac; lovin' it! Odd thing is, several months after buying it, the fan activity seems to be increasing. The fan runs pretty much non-stop all the time. Even when I shutdown the iMac, there is still something "whirring" away in there. It's soft, but noticeable. When I let the unit go into sleep mode, that fan is still buzzing away. It did not do this when it was spankin' new. When it went into sleep, everything went quiet.
Read thru the forums and google'd it, tried the SMC reset trick, and the power-off-for-a-day tricks. Still, fan is running. Verified that no wild processes are running (cpu is 97% idle). Unit is not hot near the vents. I installed that iStatPro widget (totally sweet app, btw), and it reports that system cpu temp is 31°, HDD is 46°, and fan rpm is 1196.
I'm not whining; I just want to make sure my mac does not burn down the house. I really dig this box. Any ideas?
Peace

Hello and Welcome to Apple Discussions ...
I know you reset the SMC but try this just in case, I found the resolution here:
http://support.apple.com/kb/TS1433
If you press the iMac power button while you are inserting the power cord, the iMac will enter a mode in which the fans (blowers) run at full speed. In order to correct the issue, reset the SMC and then start the computer by pressing the power button AFTER the power cord has been fully inserted.
The iMac should now start up and operate as expected.

Dell XPS l502x

I am planning on installing Arch on my Dell XPS L502x but i'm not sure which packages i'll need for my hardware (wireless, processor, and graphics card) the thing that troubles me the most is the graphcis card. Does anyone have any information regarding this?

moosie wrote:Thanks for that, that solves my graphics problem, but i'm not sure what packages i need to select while installing arch
During install I just pick 'base' and install all the rest when I have the system running.

Fan runs (nearly) fullspeed ALWAYS - XPS l502x
