Fan problem, could it be serious?

I got the widget iStat Pro a while ago & loved it. Recently, I got another another app, smc fan control, I tried it out & found no real use for it. A few days ago, I noticed that iStat shows the fan speed for only one of the fans, "Fan 0" which goes at a little less than a 1,000rpm. Before, it showed both fans going at about the same speed. Now, next to 'Fan 1' it says, '0rpm'. The temperature of my computer hasn't gone up above normal temp, (about 100F) but still, is this fan broken? I uninstalled iStat & downloaded it again, but it still says that fan 1 is at 0rpm. Is this a serious problem? What can I do to fix this? I tried paying around with the fan control app again to see if I could get only fan 1 to go at a high rpm while fan 0 goes slower, but nothing changes for fan 1. Someone please help me out. Thanks.

Time machine: An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.

Time machine backups are failing. I've followed the instructions I found on the Time Machine troubleshooting page (http://pondini.org/TM/Troubleshooting.html) but have gotten to where I don't know what to do next.
Sequence of events:
The main error message is always:
An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.
Yesterday, I opened Disk Utility and verified the disk. Got this error:
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
I ran Disk Utility and repaired the hard drive. Then I manually started the backup before going to bed, figuring it was going to take a long time to run. When I got up this morning, the backup had failed with the same "could be temporary" error. I checked the log, which says:

Does anyone know what the problem is here and what I should do?

You have repaired your boot drive (which is good) but have you repaired your time machine drive? I don't own a Time Capsule so I don't know if disk utility can operate on it. If it can, you should repair it as well. You may need to erase it and start a new backup. That happens to time machine volumes from time to time and is why people who are serious about their data never rely on a single source of backup.

Fan problem on L645-S4036 (temporary fix and a question about it)

Ok, after some days of usage on this laptop, I have found that the fan only goes to 95% of usage when I'm playing, which is normal I think... BUT also goes crazy when I turn on the laptop, and I don't use for about 15 minutes, even if the temp is just fine, with no software running on the background.
If I use it, the problem doesn't show up at all...
The only way to turn it off and lower it to about 45% (if the computer is not hot), or 0% (is so nice like that... No noise at all), is suspending the laptop, and turning it up again. Really strange thing.
I guess is a problem with the BIOS, or the temp calculation of it. Do anyone know if Toshiba is working on a BIOS update for this issue?
I'm happy with this laptop, the battery which is faulty, lasts about 2.3 hours, not 3.9 hours as said at the specifications (not a problem, warranty is supposed to bring me a working replacement... Doing it tomorrow) and the fan noise are the only problems I have found after a month of use.
I hope the temporary fix helps a bit...If anyone knows another way to fix it, reply me, because third party software didn't worked for me.
Thanks a lot!

I have TOSHIBA Sattelite L300. I have same problem. I installed SpeedFan to monitor CPU temp. I found something CRAZY about toshiba conception on temp. regulation!!! The fan stops when temperature of CPU goes under 30 degrees !!!!!!!! UN BELIEVABLE!!! It's very hard to be done... I can achieve this VERY HARD! In the room temp is 20 degr., outside is 10 deg. the laptop is on the table... cpu usage 1-2% !!!! Fan goes on AND NEVER STOPS, temp of cpu stays constantly at 35 deg. I pickup the laptop in air, or put a remote control of TV under front side, and miracle!!!! after a few minutes the temp goes to 29 deg and fan stops (of course if you standby and resume, fan stops too). But not for long... the temp. of cpu starts growing. first the temp grows fast, then it almost stops growing about 45 deg. and you say wow super! But than suddenly fan start (about 45 deg.) if it didn't start... the cpu temp wouldn't rise above 55 deg.
I have another LAPTOP, Sony Vaio, I installed SpeedFan to monitor CPU temp too... This machine has a very different conception about cooling... I can't hear it FAN ever... Tha speedfan shows this: When you use machine actively, the cpu stays about 70 deg. tha fan speed varies very smooth (not on a steps like the toshiba laptop) and when you not using CPU actively, the fan speed drops to a very slow level, almost can't hear it... have to put my ear near to where the air goes out... and from this quiet speed, the cpu temps goes down slowly, and when it's about 60 deg. tha fan stops at all... and what I see in speedfan is that cpu temps raise very slowly to about 65 deg. (this is when the laptop is over me (not on the table with remote control for more air :-) ) the fan never start if I'm not using CPU actively and the temp stays about 65 deg., when I start using cpu a little more activily the fan starts at 74 deg (at lowest speed, not like the toshiba "Buuuu... buu... bbb" - on a few steps to the lowest level starting from high) and can't hear the fan is working, just see how the temp starts falling... and when achieves 60 deg. STOPS (but you can't hear it at all). So the concept is that when you are not using a CPU actively... the CPU can cool WITHOUT FAN RUNNING (at about 50-60 deg. PLEASE TEST IT). So I think TOSHIBA MUST DO SOMETHING ABOUT IT... I can't believe that engineers thinks that every 5 min. temp. jumps from 30 to 45 deg, from 45 to 30 and this is 24/7 (if you put your remote control under laptop and you live in a cool country where outside is 10 deg. and inside is 20). Instead of CPU at constant (or at least slowly changing) temp. This is not good for any machine (cooling, heating, cooling, heating... this is bad for machinery). The problem could be solved just by changing fan on temp to 74 and fan off to 65 deg. for an example...
So I wait for a new BIOS version SOON, with updated values...
Thank you! in advance...
Other wise... NO CHOICE... change your laptop with a one with a better cooling concept...
If any one needs more info or what ever, please feel free to contact me...

Return for Fan Problem (aka mooing)?

Has anyone actually returned their Macbook for the fans coming on and off (or "mooing")? If so, did you get a moo-free MB?
The mooing isn't too bad - and I have hope that software could fix it; but if there are Macbooks that don't moo, man, I would like one. However, no point in going thru the process if there is no possibility of getting a moo-free MB.
Thanks.

There definitely ARE some that do not moo. Or if they do, they do it much softer. Last night I had a white one that, every 10 seconds, would moo. It was horrible. Even with my TV on, I could still hear that fan revv up and then revv right back down, then 10 seconds later the process would repeat itself. I certainly couldn't live with that. I'm a student and would surely be kicked out of class with a laptop that sounded like a zoo, lol.
So anyway, I returned it today (demanding an exchange). What got me is when I explained the moo'ing to the girl, she sounded surprised and that she'd never heard of the problem before. THEN she takes it in back for about 5 or so minutes and comes back out and persists my MacBook didn't have a fan problem. I told her the machine had to be running for about 15-20 mins before it would kick in. Well she's gets my exchange and then continues to tell me "they're supposed to do that." She said hers at home did it. She also even commented about the posts on these forums about it at that point, too. I was thinking, okay then why didn't you tell me that when I explained the problem? I have a feeling the manager told her to tell me that.
Well, I got my black one home today and have been using it for about an hour before work (while it charged), and now for almost 2 hours (running down the battery). I've only been using it lightly and my temp hasn't gotten higher than 60C even on AC power. Perhaps this is why it doesn't moo? My white last night was close to 70C (on light use) and the moo wouldn't quit.
Unfortunately, this one does whine (somewhat loud on AC power, but very very soft on battery). However, that is a non-issue because turning on bluetooth shuts it up right away, or using QuietMBP works also. Whine I can deal with, but there is no work around for the moo.
So, my advice, is yes, return these moo'ing MacBooks. Like others have said, the more returns they get back for this fan issue, the faster they will (should lol) correct it. There's no need in my eyes to sell a laptop that behaves such as some of these do. I do not pay well over a thousand dollars to have to sit in a zoo-like atmosphere. And that's exactly what I told the sales woman. A lot of times I sit in quiet and this fan noise is too loud to ignore. However, I really do believe this is tied to a heat issue, because it is clear some of these run much cooler on light use than others do. That must be why I haven't heard the fan on this one - my temp is much lower than the one I had that moo'ed.

Macbook Pro Overheating/Fan Problem

Here's a thread I posted on my World of Warcraft guild's forums. I'm reposting it here for additional suggestions. Please ignore the WoW jargon if you're not familiar with the game, but be aware that a "raid" is a situation where graphic intensity is at a high within the game, and can be particularly taxing on a system. Also note that WoW is 4.5 years old, and should not be all that taxing overall on a Macbook Pro compared to newer games.
My Macbook Pro runs hot. In fact, almost all MBPs run hot, hotter than your average notebook computer. The norm seems to be 150-160 degrees during high activity situations (games, compressing video, etc.) However, mine is running even hotter. Last night during the raid, it was peeking at around 174 degrees. Bear in mind that I was playing with all settings minimized, but at full resolution 1400 x 900 or whatever it is.
Now the real problem. Two nights ago, after extended WoWing, a fan on the right side of my computer (or what sounded like a fan) started to sound like it was making contact with something else in the computer, creating a light buzzing noise. After a few minutes, this noise had escalated to a full-blown, really-annoying buzz. I exited WoW, shut down the computer, and started it again after about 10 seconds. Buzzing sound was gone, fans back to normal. Decided to watch Lost on ABC.com, which got the fans going a bit, but not nearly to WoW levels (WoW levels being 4500-6000 RPMs, it's idling at 2000 RPMs right now.)
Last night, during the raid, it happened again. If you were in my 20-man raid, you heard it for yourself over my vent mic. I restarted WoW twice during the raid, but after only a few minutes the sound came back. Had to use a frozen pizza in a plastic bag as a cooling pad. Computer was running much cooler (163-165 degrees, normal for WoW on my computer) but the sound persisted. Turned off some addons, capped the frame rate at 20 fps, sound persisted. After the raid, restarted my computer, buzzing was gone, decided to watch more Lost and the buzzing hasn't been back since. I suspect it will be back during Sarth 3D tonight.

Computer was purchased in June 2007. Upgraded to 4 gigs of RAM around Xmas. In the Fall, the computer was sent in to have the logic board replaced, because the video card died. They replaced it with another 8600M GT, a card notorious for overheating and dying. Both Apple and Dell provided free extended warranties for computers using the 8600M.
Any suggestions?

Welcome to Apple Discussions!
You might want to run the extended version of the Apple Hardware Test, just to rule out any physical problem with the fan, such as a dying bearing or something like that.
That said, it sounds more like there is a physical interference of some sort. It may be when the Mac gets hot, the geometry changes just enough that a fan blade could start rubbing on the housing. Or possibly there is something caught in the fan blade, like the leaf in my Dodge truck's AC fan that makes noise whenever it is turned up high.
I don't play WOW myself, but I understand that it will make the Mac run hot, and at 6000 RPM, the fans will get a lot of use. There's always the possibility that they might wear out sooner because of that. It's probably a good idea to run the AHT every so often to check for signs of premature failure.
Good luck!

Notebook fan problem

Hi,
I've had my laptop for 2 years now, my laptop: Compaq Presario CQ60 Notebook PC, has a fan problem. My fan stopped working when I turn on my laptop. After using my laptop for a while (when it starts to turn overheat), my fan kicks in and only works for exactly one hour, after the hour, my fan turns off. While the fan is on, it cools down my laptop. My fan won't working again until a couple hours later or when I restart my laptop and wait for it to overheat again.
Can anyone help me with this problem?

If you just bought it and it's only a few months old then it should be covered for a replacement. You shouldn't be forced to buy a new one, HP should give you one to make it right.
I hear you, if you are busy you don't have time but don't let them swindle you. At least give the computer to someone who does have time and tell them to do a web chat the warranty people and explain that it runs at 98 C (or over 200 F) and that it needs to be replaced and could have burned you. Do this before the warranty period is gone. I think new computers come with a year warranty.
I say webchat because it is easier to keep a record of who you have spoken with and what they say in case they try to weasel out of replacing it. If they give you any trouble about it, post the log or send it to me in a message and I will tell you how to deal with them.
For several months I had to send emails back and forth and go through three years of receipts to get them to honor a warranty and I saved the logs of our chats and I know every sneaky trick they use to try and deny people service.

T5220 Fan problem

Hi,
sorry if this is the wrong forum.
We have a T5220 in the office, yesterday this message appeared
"Jan 30 12:34:06 T5220 SC Alert: [ID 118048 daemon.alert] IPMI | critical: ID = fc14 : 01/30/2009 : 12:33:06 : Fan : /FB0/FM0/F0/TACH : Lower Non-recoverable going low : reading 1600 < threshold 2400 RPM"
Could anyone shed a bit more light on this? It's obviously a fan problem but will it need to be replaced?
Thanks,
Paul

I would have the fan replaced. The fact that it is spinning way under speed is an issue as these very compact boxes require forced airflow.

G4 MDD Logic Board or fan problem ?

I recently posted thinking my problem was a dead battery.
I replaced the battery and still had the problem.
here's what happens:
Once the G4 MDD is powered up and heats up, the fan comes on and stays on high speed. Eventually it sends the G4 into sleep mode.
Once this happens, I can't wake it up or power it down, unless I pull the power cord.
After replacing the battery, I reset the PRAM. no luck.
I also tried resetting the PMU, no luck.
I think there is something wrong with the logic board or the other fan (the one directed at the heat sync).
The heat sync is extremely hot, and the larger fan that is directed at the heat sync does not turn on.
I just found this article when I did a search for power mac G4 fan: http://docs.info.apple.com/article.html?artnum=95038
in that article, it mentions 2 LED's that should be either both on or both off, and there is only one of these LED's that is lit.
<1. Power Macintosh G4 (PCI Graphics): Check LEDs DS7 and DS8 on the logic board. In a working unit, these LEDs should be in sync with each other: both on or both off. If one LED is on and the other is off, there is a problem.>
any idea what this means ?
Is it a fan problem, or a logic board problem ?
This G4 was in storage for 5 months during a move, if that clues anyone in to what is going on.
thanks in advance for any ideas,
Steve

Hi
If it were me I start by assuming it's a simple problem with the fan as it would be the easiest and cheapest thing to replace. It should be spinning to expel the hot air around the heat sink fins out of the back of the case. I expect the computer reaches a certain temperature and goes into sleep mode automatically to prevent any permanent damage to the hardware.
Replacement instructions can be found here:
http://www.info.apple.com/usen/cip/pdf/g4mdd/g4mdd-lowerfan.pdf
I'd start by checking the fan's power connector is still fully seated and the fan isn't clogged up by dust etc. You could also try giving it a help in hand by giving it a spin with the point of a biro to see whether it's just sticking.
I'm not sure how relevant the article you linked is, as if refers to a much older model and I think it's only applicable if the computer is completely dead, i.e. no power and no fan movement.

Post-Gaming Fan Problem

Hey, I got the 15'' mbp in early June and I also happen to be a gamer. I have been playing WoW for 2 years off and on. I used to play on a basic $500 hp from 2008. When playing the last expansion (wrath of the lich king) the old computer's fan broke on two occasions and I ended up not being able to play. Then I looked into this new mbp because of the upgrade in graphics and read reviews that it would handle WoW easily. When playing WoW, I had very good graphics but the I could hear the fans working. Which is normal. I got a cooling fan (the iHome) just to help a bit. After a 2 months of playing I started hearing the same noises I heard on my old laptop. I could hear the fans pretty clearly even when using basic programs such as internet, openoffice, etc. I just downloaded smcfancontrol and it says my rpm is ~2000 and at ~150F. I was thinking about going into an apple store and having this laptop sent back to get the fans replaced/fixed. What is the actual problem?

Thanks, I happen to have applecare so I am going to call in when I can and see if the best thing to do is to just send the mbp in to have the fans replaced. It's just when I see my friends' mbp's, theirs are very silent even when streaming videos and my laptop gets extremely hot when streaming youtube videos. Do you think I'll be able to go back to playing WoW even with their new expansion? My laptop ran it amazingly except for the fan problem. Maybe some tips as to what I can do to help prolong my fan's/laptop's life? When I play WoW, I have the cooling fan hooked up and on and I have my laptop plugged into the power adapter. Then I place it on my lap while laying down. Any suggestions? Thanks so much for your help. Much appreciated!

Mid 2009 macbook pro battery is dead and fan is constantly ramped up (not due to heat). Would installing a new battery fix the fan problem?

Battery icon has an "x" over it and I need to have my laptop plugged in to be on. I've ordered a new battery to install, but I was wondering if it's possible that something else might be causing the fan to be on over drive constantly. I've tried resenting the SMC and the PRAM, but nothing has stopped the fans from running at higher than normal speeds.

If you've updated to Mavericks, you'll either need to use the original install DVD containing the AHT, or download the right one from Apple's servers, then replace the hidden /System/Library/CoreServices.diagnostics folder.
I think that replacing the battery is likely to stop the fan problem anyway.

On my Mac Mini, I keep getting this error message: "iCloud encountered an error while trying to connect to the server". I don't have any problems with iCloud on my laptop / PC. It works fine... Does anyone know what the problem could be?

Your Mac must be on Lion (10.7) to run iCloud. Apple had to change the operating system to fully support it. Nevertheless, it is possible to get emails from iCloud without having Lion. Please tell me if this interests you.
Anyways, here is the link to buy Lion (30 dollars, totally worth the upgrade ): http://itunes.apple.com/be/app/os-x-lion/id444303913?mt=12

Installing Oracle RAC problem: Could not determine /tmp mount point

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
I am installing Grid infrastructure. I am on step 7 of 10 (verify Grid installation enviroment) and get this error:
"Free Space: Rac2: /tmp"

Satelite l655 - s5094 - werid cooling fan problem

ok here the deal when my laptops is around 40 C the fan runs at 100% and as the temp rises it slows down to bare min and when the temp hits high then 70 C it gose back to 100 %. i got a colling pad but it barly helped. and fan control with speed fan out of the question unitll they support the laptop. if there a way to change the fan setting that would be great to know.

Heatsinks don't need to be changed. They need to be cleaned, which you've done.
It's not clear from your post, if your fan problems persisted after you cleaned it. If they have, sounds like the fan is failing to me.
Try one these. Got the part number from here. From your model's parts list here.
Please let us know how it works out. Good luck.

BIOS 902 cooling fan problem

Today, I powered my laptop and see the error BIOS 902, cooling fan problem. Then the laptop shutdown. However when I tried to power the laptop at third time, It can start up normally and I can use my laptop for more than 8 hours
I found the solution in google that upgrading the BIOS. However the error 902 still there. My laptop always start up normally at third time.
What should I do? Should I bring my laptop to warranty center?
Thanks for your advance!
