Fan problem on my Macbook
I have noticed that my fan runs more and more on my Macbook. Does anyone know what´s the problem?
It starts more when I use Youtube videos etc
Depends on what you mean by "before". If you mean last week, you might have some sort of issue. If you mean a year or two ago, then its probably normal. Youtube is constantly increasing the quality of its hosted videos. Most used to be low quality and easily played on your MB, but now most are high quality or HD quality, and your computer simply has to work harder to play them. In fact, I found that the older G4 powerbooks are basically useless on Youtube as they can barely play todays videos.

MacBook (13inch-late 2009) Heat/fan problem?? (2.26Ghz, white unibody)
Hello guys, I have, maybe a problem with a unibody MacBook 2.26Ghz.
Many times i have noticed that it is quite silently with his fan, even if some process are taking lot of CPU. For example, my MacBook Pro 13inch mid 2009 is not so silent, cause the fans runs faster. For example, now that I'm writing on it, the CPU temp is 55 degree and fans runs at 2500rpm. I think could be normal, even if most of the times I would prefer it would not cross 2000rpm for low temp.
By the way, interested about the fan speed of this macbook unibody I have started a hard process that was taking lot of CPU (A VLC video mkv playing at very-very-very high quality). Around 90 % of both cores was used, so the temp started to gone up as normal.
The strange thing, is that even if the CPU was running from 50, then 60 then 70 then 80 and over degree, the fan speed was still at 2000rpm. The fans was not taking care of this high temperature, all was normal. The video played for many minutes, and nothing happened, the fan was still at 2000rpm, some rpm more, some rpm less.
On my Mac Book Pro, the same process cause an increase of fan speed quite after the CPU starts to get stressed at high percentage.
I have manually tested the fan of this macbook, and it is able to go at faster speed, the classic 6200rpm can be reached if someone ask it to run at that speed.
So, now I ask you guys, does is normal that this macbook quite ignore this hard temperature and not start to cool the CPU on this high degrees? Does I have to wait more for fan speed (i have waited at last 5-10 minutes)?
My fear is that the heat could damage the CPU or cause any other hardware problems...
let me know please
thanx!!
AndreaI have the same Macbook type. You can try resetting the System Management Controller. The details are in this link:

hello i have a problem with my macbook pro become to slow to write any thing, to do any thing and the fan is always on never stop what can i do?
i already reinstall the software many times and still the same i dont know what is happening is there is somebody who can help me please im will waitingThere are any number of possibilies... you could have problems with runaway applications, causing your machine to overheat and setting the fans off, you could have bad fan sensors, etc.
Open Activity Monitor (Applications>Utilities) and see if you have any apps that may be hogging the CPU. Call back.

How do you resolve the problem on a MacBook Pro of a blanks screen, no backlight, fan is running, nothing will eject, and mac won't respond to resets?
My gut response would be to Boot from that install disc and do an archive install ...

Hi. Just today I have had several random shutdowns. Had the Macbook for 10months now and it's been brilliant so I was a tad surprised when it started playing me up!
After a few looks on google it seems lots of people experience this problem with different reasons for it. I first thought it was the system fan as it did seem very hot but the fan hadn't kicked in. I tested the fan but I got a reading of 0rpm. SO I then ran the Hardware test and got the following error message:
4MOT/1/40000002 :Exhaust
So, I'm deffo thinking it's a fan problem and the CPU is shutting down cos of the heat. Now, I did not buy the extended warranty but I have checked with my serial number and have until Feb 2008 on the standard 12month warranty - my next step is to contact Apple to see what they will do. Does anyone know whether I am assuming correctly and if they know what Apple may do for me?!?!

deffo?
I have no idea if it is the logic board or not. I know that Macbooks do not have many serviceable parts. To get to that fan may be a major undertaking. Typically, they want to get the unit repaired and back to the customer as soon as possible. They will swap out what they can do the fastest and diagnose and fix the actual broken part on their own time (or just toss it in the trash). But, of couse, I am just guessing.
How long would it take to replace this?!?
I have no idea.
Can't believe it - I love this notebook!!!
It is not as if you have many options. It will be a paperweight soon. They are machines and all machines break eventually. Either you have the misfortune to have one that isn't perfect or the good luck to have it break while the warranty is valid. -
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. -
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. -
Noisy left fan on brand new MacBook Pro 15" (started after 4 days)
The left fan (just under the speaker) is making noise, sounds as if it's catching on the casing or something.
Problem is, the Macbook is non-standard (hig-res matte display) and I need it painfully much for the next two monts - it was bought specifically for the purpose of major jobs.
Is it possible to have it fixed in a day or two or does it require ages and ages?
Thanks!My MBP (Mid 2009) just started doing this on the left side, and I've had it apart several times trying to clean and re-lubricate that fan. The sound is not as bad now, but the increased fan noise is still present and I'll be shelling out $50 for a new one probably tomorrow. I'm putting up a YouTube video so you can hear the awful noise it was making last night (harbinger75 movies there).
Mine's not under warranty anymore, and I've been a Mac/PC tech for years, so it takes all of fifteen minutes to change one out.
Hopefully, they'll just replace the fan for you. -
What would Apple do about these problems with my macbook?
I have the following problems with my macbook (only problem is i dont have a receipt because it was a gift but it is registered with a year left) and i was wonder what would apple do about them?
Slight blue discoloring around the edges of the macbook and around the mousepad/mouse button
Gets very hot
"Mooing" noise
Lcd bezel is not lined up correctly
Those are the top 4 i could think of, what do you all think? thanks!They wont do anything about the heat as that is something that happens to all macbooks.
They might switch your fan out for a different model to eliminate the moo and they'll probably replace your discoloured plastic. If you mention the lcd bezel they would probably do that when they fix the other issues, if you dont tell them its a problem they might not do anything to it.
I wouldnt worry too much about not having a receipt. i should think an official apple store would take it in, even if they just sent it off to a repair center. Theres no way they can argue that its out of warranty considering the macbook hasnt been out anywhere near a year. -
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. -
How many had fan problems with PbG4 12?
After only 3 years of very gentle care, my fan is growling and may need to be
replaced. In my computer experience, I have never heard of a fan quitting in the
first 3 years.
But, is this a common problem of this model? If it is, then shame on Apple for building expensive
computers with cheap components.
So cast your vote:
did anybody else experience fan problems with the PBG412?I've had my 12" PB for 4 years now, and I have ever had a problem with the fan. My has workeed fine from day one. I still use it from time to time and, in some ways, prefer it over my Macbook.

Strange fan noize with black macbook, sounds like a cow!
Hi
The fan noize on my macbook has been getting worse and worse as i go, its been almost a year since i had it and now its starting to really make seriously LOUD noize, at times it sounds like a cow choking on and off.
While the computer is under a insurance which covers any accidents or things like this, i am hoping i can do something before i bring it to the store i got it from and wait a month before i get it back.
can anyone advise here?Sounds like a cow eh? You might have a case of the moos.
No kidding! This was a common problem on early core duo MacBooks.
You can also listen to a mooing MacBook here.
