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!

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!

IMac 27" (mid 2010): Will replacing the HD cause fan problems?

Hi,
I have an iMac 27" (mid 2010). My HD is broken, and I'd like to replace it. I've already installed an SSD, so replacing the HD shouldn't be much of a problem.
However I've read that replacing the HD causes the fan to spin up all the time. Some sites say this started one generation later, but some remain unspecific or say that this problem affects all iMacs. Before I replace my HD, I'd like to know what to expect.
So my question is: in my 2010 iMac, can I replace the HD without causing fan problems (provided I put the temp plug in the right place )?
Best regards,
F

OWC is mistaken. I don't know why they keep saying that. (I'm not even certain the OWC blog linked above related to using the same make drive on the late 2009s was ever correct. I had a long phone conversation with an upper level WD tech some time ago who said that the originals were special ordered by Apple.) Those drives have Apple proprietary firmware which puts the temp sensor output to the jumper block, and you cannot just replace with a drive of the same manufacturer. A non-Apple WD drive will not have that connection at the jumper block.
Two possibilities: Get an external stick-on temp sensor that will work with your model or use SSD Fan Control.
http://exirion.net/ssdfanctrl/
If I'm mistaken and you do get it to work directly with a replacement WD drive I will be pleasantly surprised, since I have a Late 2009 which will need a new drive sooner or later. Please post back with your results.

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.

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.

G5 Fan Problems with Leopard

I'd had problems controlling the fans on my dad's G5 tower under Tiger (and also under Panther), and I was hoping that they'd be solved once I migrated to Leopard. No such luck, it now appears. Before, the fans would only ramp-up in my user account, because that's where I did most of the system upgrades/updates. Now they do that in anyone's account, not just mine. Today I found that my mom had left the computer on unattended, and after an hour of doing nothing a kernel panic had resulted, with the fans going full blast. I managed to shut the system down, and barely averted a real disaster.
I need to know if there is something I can do to permanently fix this problem. Going into Energy Saver Preferences in each user account, and setting Processor Performance to Highest, won't serve as an adequate solution for long. Is there a firmware upgrade that can handle this? (I think there is for other systems IIRC, but not for a G5 tower that I know of.) The fan control problem has been with me through many system updates in Tiger and Panther, as I said, and short of buying a new Mac I'd like to know how to fix this.

I did indeed upgrade from Tiger, but no real options were given to me in installation (and I did not click on Customize). The only incompatibility I've seen to date has been with the print driver for our HP DeskJet 842c--the Leopard driver went haywire, so we had to reinstall v2.7.1 from the HP support site. Other than that, everything's been okay otherwise. I'm preparing to update anything else that needs updating, such as vital utilities.
The fan problem is what I believe caused the kernel panic. It's happened twice to my knowledge, and in both cases the computer was left on with the login screen up, and with no attempt made to login to an account. The computer was simply left on with nothing to do but attempt to self-destruct. (I have since posted a sign near the computer warning against this behavior on the user's part.)
The fact that the fans go berserk in this thing is why I ask if there's a firmware upgrade available for it, though by now there may no longer be any official support for G5 systems now that everything's gone Intel. I'm planning on getting a Mac of my own one day soon, but my folks can't afford a new system of their own for quite a long time to come, so this is it for them. And it needs to work properly. My mom likes to remind me that some people leave their systems on 24/7 without ill effects, but I remind her that we aren't as blessed as those people to have such a system. I really need a working solution to this.

IMac G5 1.6GHz 17" screen w/ 512mb RAM and a fan problem

I do not know if anybody else has had this problem, but I have a fan problem, my computer is very loud, I have seen other computers that are the same as mine, I think I have a very loud fan and it goes all the time.

Hello Walter - I am glad your problem has been resolved. What was probably not stressed enough in the posts you read is that you have to have a retail version of any new OS you want to install. Failing that, you would have to get install discs for exactly the same model iMac you have.
Make sure, that when the Keene store installs Tiger for you, that they give you the install discs so you can boot from them if you have any other problems. You might also consider getting more memory, you are operating with the bare minimum. Don't buy it at the Apple store, order it on line from [macsales.com] or [newegg.com] or [smalldog.com] it's much less expensive and really easy to install. Make sure that whatever memory you do buy has a lifetime guarantee.

Mac Pro Fan Problem

Hi, I have been having some problems with a Mac Pro I have been working with. At the Start-up the Fan goes to top speed and once it logs-in the fan is still pretty loud. I've checking the Temperature of all the computer parts via a Temperature Diode, and its normal and not high. After searching the internet for hours looking for posts that were for the Mac Pro and not for the MacBook Pro (which comes up in about all the searches using the words Mac Pro Fan Problem) and I found some software all of which is not for Mac Pro's. Is there any application I can run do reduce the RPM of the Fans, Reset the Fan Speeds to only turn on when it get hot, or something along those lines.

Thats odd, seeing as Apple have it listed in the Support article:
To reset the SMC on a Mac Pro:
1) From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2) Unplug all cables from the computer, including the power cord and any display cables.
3) Wait at least fifteen seconds.
4) Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5) Press the power button to start up your computer.
It does exactly the same thing as the SMC_RST button, simply by removing all power from the system. I would assume the reason for this would be that the SMC settings are stored in RAM, which is erased once the power is removed from the board, hence the minimum 15 secs wait which gives time for the capacitors in the power supply and system to discharge.
So yeah, it does do the trick, or has done for me in the past a few times.

X61 Speedstep and Fan problems

I have just got my X61 for a few days, some problems immediately concern me.
The first thing I noticed after running it for a few hours was that, the fan never stopped spinning! My machine comes with a Core 2 Duo T7500 2.20Ghz CPU. I have already set "Optimize fan control" to "Balance all parameters" and the fan never stops, even when the machine is in idle with the lowest CPU speed.
I did a search on forum.thinkpads.com and I found that many people have the same problem with their X61 and X61s too. The general solution is to turn to a program called tpfancontrol written by one of the forum members there. The program allows us to override BIOS fan control and set thredshold for when the fan kicks in. It works, but the problem is that even at the lowest fan setting allowed by the program, namely "1" ("0" is off), the fan is spinning at 3207 rpm and that is quite noisy.
I am a graduate student and I spend most of my time in my office (shared with other people) and in the library. The level of fan noise this machine generates will certainly disturb me and my colleages.
The second problem is about speedstep. Since I want to prevent the fan from spinning all the time, the first thing I did was to try to reduce the heat output when I am just serfing around and checking email. I installed the latest version of CPU-Z to monitor my CPU clock. I noticed that setting the CPU speed to "low" and "lowest" have no difference. Both setting clock my CPU speed to around 1596.5 MHz, with a multiplier of 8.0 and Bus speed 199.6 MHz. However, if I set CPU speed to "adaptive", my CPU can be clocked as low as 1197.5MHz, with a multiplier of 6.0 and Bus speed 199.6 MHz when it is in idle. Why can't I lower the multiplier to 6.0 and achieve a clock speed of 1197.5 MHz when I set the speed mode to "low" or "lowest" (and why are the two modes the same?)
I have already downloaded the latest drivers and all the thinkvantage updates. My questions and suggestions are:
(1) What is happening in speedstep? Why "low" and "lowest" are the same? And why "adaptive" can achieve a clock speed and multiplier lower than "lowest"?
(2) Fan problem, as noted above. It is a pity that we have to turn to a 3rd party program to solve the fan noise problem. Lenovo should add more flexible fan control functions to Power Manager.
(3) How can I set my fan to run at a speed between off and 3207 rpm? I am using tpfancontrol to set my fan level to "1" when the CPU temperature reaches 55C, and off below that. What happens is that: 0 rpm -> heat builds up -> 55C, 3207 rpm -> after 10 seconds, cooled down -> 0 rpm -> heat builds up -> 55C, 3207 rpm ...and so on. The 3207 rpm is certainly no a pleasant sound in a quiet room.

If you have read my post on TPF you should know that I have already tried NHC and no it doesn't work. It can't even recognize the correct clock speed due to the fact that it cannot recognize the change in Bus Speed.
No there is no any Intel utility to control the speedstep. Power manager is a Lenovo Thinkvantage program and as I reported above, the "low" and "lowest" seem to be exactly the same, neither of them can reduce the multiplier to 6.
The reason why I am posting here, after getting no reply at TPF, is that apparently I have tried all the popular 3rd party softwares and none of them can solve my problems. It seems to me that the speedstep and fan problems require a BIOS update or an update to the power manager (or even a fan upgrade?), which I believe is something beyong the reach of a normal thinkpad user. Since this is the official forum of Lenovo, I am hoping that someone from Lenovo can answer my question and provide official solution, rather than asking me to try yet another 3rd party software that doesn't solve my problem.
At least I would expect a person from Lenovo can explain to me why the "low" setting seems exactly the same as the "lowest" setting, if it is not bugged.

PowerMac G5 Dual 2.0 fan problem

I just bought a Powermac G5 dual 2.0 (June 2004) with 4GB (aftermarket) RAM on eBay that has the 'constant on' fan problem. I have run every series of tests and tricks that I found on the internet and it is still stuck. The machine runs flawlessly, all benchmark tests that I have performed have been completed successfully. In addition, I have done the following:
The door/deflector sensors are working properly, no red LED on the board
I ran all of the OF and OSX ASD 2.5.7 tests on it and they came back clean.
I reset the PRAM, the SMU, PMU and did the NVRAM resets in OF.
I repaired the disk permissions
I reseated the video card
The machine is spotlessly clean inside
All temperature sensors are functioning properly, and the Dashboard thermal readouts I downloaded show the temps are well within normal parameters.
I zeroed the HD and installed a fresh copy of OSX10.5
Nothing I have done has affected the problem at all... Does anyone have any suggestions on what else I can try to solve this problem?
Thanks,
Joe

I'm sorry nothing worked. I should have known you would have tried those things. The thing about tiger and fan issues I heard about just a few days ago. You saw which versions were fixed and unfixed though right? Right. Reduced power does nothing too I guess. And turning off sleep. It just doesn't sound like the Jet Sounds that other users have reported regarding their fans and sleep or where the fans go into Panic mode to cool the CPU Temps. Speaking of which I recommend Temperature Monitor to see just what temps you're running at. If they are too high that might be the one explanation.
And one wise Mac forum guru from Japan said something to the effect that most fan issues had something to do with USB problems. I hope he'll chime in, he's very good.
What else... false sensor readings? I have no clue as to where they really are to fix.
I sympathize because I've had fan problems of my own since I bought this mac used about two years ago. Loud revving up and down on Highest power setting... sounds like a demented banshee. Luckily I can just run on reduced power and it keeps the worst at bay.
The Mac I had before this one was a Dual 2.0 like yours. It was a rock solid performer for several years before I put leopard on it. Within a week it was dead as a doornail.
Well I think I've exhausted my ideas on this one. I'll keep thinking about it though. Oh, two more. The first, some kind of cool enclosure that muffles the sound without killing your Mac. The second, and what would be my preferred method if I was rich, would involve a very large hammer and...
Anyway, I really hope you solve this, Joe. If you do, post back and let me know how you did it.
Ack, looking back at your original post I see you already did some of the things above. Sorry, it's late and I'm too tired to edit.
Ok, one last thing I don't think you said but just occurred to me. Have you looked under the cpu cover to see if anything is amiss there?
That's it, I'm spent for now.
Good luck.

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.

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.

Not posted Treasury transactions- problem with new Business area (NewGL)

Hi all,
I have to change the Treasury account assignment objects due to a restructure. Currently, all TR transactions are assigned to one business area only.
In future, there will be 3 (different) business areas.
I have added new products, transaction tpyes etc and I have made further customising
settings. It looks ok and I can enter new transactions, settle and post them.
Problems I do have with already existing deals (fixed term and Forex transactions).
In here I get posting errors with message:
Balancing field "Business Area" in line item 001 not filled
Message no. GLT2201
I have added additional account assignment references for the new Business Areas
and assigned to product types and account assignment
What happens when I create a deal?
Is that information (product type/ transaction/ account assignment) alreaedy stored in a table and used, when processing the deal further?
Can I somehow change that original assignment per deal now?
I think my problem lies in that the system wants to use the old assignment but also the new and it comes to conflict in field business area.
Any hints much appreciated and will be reqarded as usual.
Thanks
Hein

Assign Business area in the following step (ECC 6.0)
SPRO - Financial Supply Chain Management - Treasury and Risk Management - Transaction Manager - General Settings - Accounting - Link to Other Accounting Components - Allocate Additional Account Assignments to Account Assignment References
