Very loud fan after suspend mode

Hi,
i installed the current arch version on my sony vaio laptop.
when i close my laptop the machine goes into suspend mode. when i open the laptop, after 3 seconds or so the fan starts. Very very loud.
I had the same issue under ubuntu. after some googling i found some forum entries about a bug within the kernel.
the output of sensors shows me that everything has no critical temperature.
Has anyone same experience with noisy fan after suspend mode?
Thanks
Marko

It will or can happen but you can reduce it somewhat maybe using SmcFanControl (2.1.3.1 - wwww.macupdate.com ) to keep the fans above default by 200 rpm. And run Hardware Monitor to monitor temps as well. They may be running much warmer than they could/should/ought to.
1GB and your system was on starvation express! ouch. 4GB is more of a normal minimum even. 4 x 1GB is nice balanced setup. 2GB DIMMs might be warmer, run 70C perhaps. And they use about 15W each.

G4 not starting up, black screen, noisy fan, chimes OK then nothing, after a few mins very loud fan!

Anyone else had this? On start up chimes as normal but screen refuses to come on. Have swapped monitors and same happens on the newer one. G4 was making noises before last week with very loud fan cutting in from time to time. Got lots of work on that computer! Typical, not all backed up! Is it the logic board? How much does that cost to sort out?
Thanks for your help

Hello, it's going to be tough to find anybody to work on G4s these days, Apple doesn't.
Have you blown the dust out lately?
Does the Video card have a fan on it? Does the fan spin freely?
If worse comes to worse, you can pull the drives & get the info off of them with one of something like these...

Loud fans in sleep mode 20" G5 iMac Rev A, OS 10.4.11 New Info

This is more of a confirmation and heads up on a problem I encountered and solved to see if any of you have other ideas.
Several weeks ago I replaced the power supply bought from Mac Pro Online in my G5 iMac. When I put it to sleep I hadn't noticed anything odd at first because I'ld just walk away until one day I could here the fans going full blast. The screen was off as usual but the sleep mode light wasn't on while the fans were running. I waited about a minute until the fans returned to normal speed and the sleep mode light returned to its usual behavior only it seemed to be a lot brighter.
I awoke the iMac from sleep and all was fine. I put it back to sleep and the screen shut off as usual but the sleep mode lights wouldn't turn on. I waited about a minute and listened to make sure that the iMac hadn't shut down and then the fans started up full blast for about 30 seconds and then returned to normal and the sleep mode lights turned back on.
I shut the iMac down, disconnected all USB and ethernet cables and reset SMU using the unplug power cord, 10 second wait, replug holding down rear start button. Fixed it!
Swapping out USB devices I narrowed it down to a Kingston USB Multi-sized port memory care reader hub-part number: FCR-HS219/1. I tested and got repeated results described above reconnecting it and downloading some images and ejecting. Loud fans in sleep mode happened again.
Tried a MobileMate Memory Card Reader, downloaded images, ejected and no problems with sleep mode.
My question is what could've messed up the Kingston Card Reader? It was working fine before the power supply replacement.
Thanks,
Tim

There's no telling.
Only cause that came to mind is a lightning hit last week that sounded very close by where all it did was cause the lights in my home to blink. The computer didn't. However, this might have fried the Kingston card reader.
To give an idea of the resilience of the former power supply, about a year and half ago I had the back off with the iMac sitting upright on a towel on the table while I played a YouTube video to see if I could cool this thing down. Instead of cooling it I overheated it by blocking the vents to where suddenly the iMac just shutdown. I could detect a strong smell of melted plastic from the power supply.
Put the iMac back on its stand and restarted without a hitch and I've never had any problems until several weeks ago when it just started shutting down for no reason. It passed the LED light test as it still does now with the new power supply.
This is the first Mac out of three I've had since 1998 that allowed me to see odd behavior like this. I had to rely on my 2000 Pismo G3 PB to find a replacement PSU online. That thing never breaks.

Very loud fan upon starting imac. Does anyone know how to fix?

My iMac has a VERY LOUD fan that turns on during start up and does not stoop. I tried to shut down and start up again. I also tried to unplug the machine overnight. Still happening.
Anyone have a solution?

This is a part of the larger MacBook Pro connectivity issue. There are several related threads dealing with the MBP's networking problems. If your unit is suffering from this type of difficulty, good luck ... (or a long ethernet cable)
(PS Everybody please make noise on this one so apple comes up with a solution.)

What is causing the very Loud Fan noise everytime I use the computer? What is causing the Heat as well? Please help

Please Help!
My computer has been making very LOUD fan noises. I know this cant be normal. How can I fix this issue?
This has been going on for a while now. As soon as I turn on the computer....the noise starts.

Go check out Activity Monitor on your Mac. It will show you which programs are running, and how heavy their use of your CPU is.
When mine does this, for some reason, I have a bunch of "Managed Clients" running at once. I use Act. Mon. to shut them down, and my Mac runs normally.

Loud fan after logic board replaced

I just had the logic board replaced on my 17" iMac after it would not power up (apple did it for free because they said it was one of the defective boards). The fan now is VERY loud. I have tried reseting the SMU, setting the CPU speed to something other than automatic. Nothing seems to work. Top say the machine is idle 95% of the time... Before the board was replaced it was VERY quiet... Any ideas?

Greetings and welcome to the Apple boards.
Miriam is right. Take it back and have it repaired correctly. We have good consumer laws in MA so they have three chances to get it repaired correctly or they owe you a refund or a new machine.
Be firm yet polite.

Very loud fan, blank screen, nothing more on power-up

I'm hoping for a miracle here... just bought the PB in december (4 months ago). ran fine last night, on battery. plugged it in, burned a CD, ejected it, no problem. shut the lid halfway. came back 30 min later. was still plugged in but had shut down completely. tried to turn it on but only the fan came on, VERY loud and foreceful, and nothing else. then the fan stops and the PB is dead. computer was not hot, though. left it off overnight, and now the same thing happens when I press the power: fan comes on VERY loud, lasts about 10 seconds, then everything goes dead.
I've done the PMU reset, nothing. tried starting with [CMD + o f] and didn't work either. I can bring it to a genius but there are no appointments left today and I need this thing to work! any ideas? thanks!

yes, I'd planned on that already but I'm an hour drive from a genius.
I've tried everything else as well. it's just dead as soon as I turn it on, except for the fan. none of the keys work (including all the key combinations that are used on startup). it's as if the PB thinks that it's too hot, so it runs its fan on startup and then just shuts down. open firmware, resetting PMU and NVRAM etc, running as firewire slave drive, start in safe mode, single user mode: none of these work. the only other sign of life (other than the fan) is that the caps lock key's light briefly flashed on powerup. that's it.
I was hoping this might be something someone else has seen. since I'm not getting the "?" icon (indicating missing OS) I'm thinking it might be hardware but NOT hard drive related.
thanks all!

Very loud fan (or other part?) noise in MacBook Pro

Greetings! My fan (I assume) has recently started making a very loud, horrible noise that sounds like a piece of plastic stuck in the spokes of a bike. It's driving me crazy and making me a burden to be around me when I'm working...which is always. Please help! I'd greatly appreciate it.

Perform a SMC reset:
http://support.apple.com/kb/ht3964
If there is no change, open the MBP and examine it. Look for dirt an debris, and if found, clean it out. You will need a #00 Phillips driver.
If still no success it may be that the fan is faulty and should be replaced. Make an appointment at an Apple store genius bar for a free and definitive diagnosis. It is not an expensive repair.
Ciao.

Brand new U500 has a very loud fan

I received this brand new U500 (customized on Toshiba.com) about 10 days ago - everything works great (love the back-lit keyboard) - but the fan noise is a little louder than what I'm used to. I had a 6-yr old Dell XPS with a quieter fan than this brand new Toshiba machine. Basically if I'm standing 20-30 feet away from the laptop I can hear the fan, and one can wonder if this comes from a refrigerator or a vacuum cleaner working in the background.
Has anyone had a similar experience - is this fan noise something I should just learn to accept or do you think I should do something before the computer comes out of warranty? I really would hate to have to return a brand new computer, but at the same time I think fan issues only get more numerous when a computer gets older.
Just for info, the machine is Satellite U500-ST6322, CORE 2 DUO P7450 2.1GHZ, 4GB RAM, DVD Slot load.
Thanks a lot.

No, that wouldn't make a difference. eMacs are famous for their very noisy fans.
Some say they were originally intended as turbine impellers for Boeing, but were rejected as too large. So Apple picked them up, and modified them for use in the eMac.
eMacs were made to be workhorses in classrooms and their robust design includes that heavy duty fan, which does impose itself quite loudly.
Some people have installed a means to introduce resistance to the fan circuit to lower the voltage and hence the fan speed, in an attempt to quieten it down.
Whilst this practice seems to work, personally I would be concerned about that causing overheating as during summer things can get very hot here, though perhaps would be less concerned if living in the UK.

Very Loud Fan

the fan in my macbook is making a very loud noise and is very annoying what should i do?

Take it in to be serviced.

Old and new battery both ~2 hour life, recently very loud fan

1)
My macbook pro, which was purchased April 2006, had suddenly dropped its battery life from about ~4 hours to ~2 in January. I noticed this because I traveled back home by plane with a 4 hour battery life for winter, and within weeks the life had dropped to ~2.
I already reset the system (i.e., remove battery, hold down start for 5 seconds, etc) with no avail. This was with the old battery. The apple store tried the same thing, was stumped, and decided to just give me a new battery.
The older battery was the replacement for the 'dud' my macbook pro was originally given. This new battery should be perfectly fine, but the battery life is still ~2 hours. I tried the system reset with this battery--which didn't work. I have also reduced the battery life to just about zero then charged it again--which didn't work.
Could there possibly be something wrong with the hardware? What can I do to fix it, what is the best course of action to fix this one problem?
2)
Just a few days ago a fan in the top left corner has begun to behave strangely. It has become very loud and seemingly inconsistent even with low CPU usage. By inconsistent I mean it sounds as if it has become loose or it won't maintain a constant speed. The best description for the sound would be 'boiling water.' What could be the cause for this and how can I go about fixing this problem?
Any input is greatly appreciated!
MacBook Pro Mac OS X (10.4.8) Purchased April 2006

1)
Have you checked your battery's serial number against the MBP battery exchange program? I did this out of curiousity with mine and it turned that mine was one of the faulty ones! So Apple sent me a new one and I sent the duff one back. It was still fairly new at the time so it still held a good charge.
2)
I had the fan thing but mine was on the right hand side. Your BEST bet...(what I did) open up quicktime and RECORD the noise several times at different operating conditions and save the files.
send your machine to a service centre and ask for an email address to send the files to so the technician can hear what you hear. I recorded it behaving normally as well so they could hear the difference.
The 1st time mine went in it behaved itself for them so they had to give it back to me, that's when I recorded the noises! I emailed the files before I sent my MBP back again, they took one listen and said they'd order the fans, BEFORE I sent it in. They called me to say that the fans were in so in it went for the replacement.
Hope it helps - mine sounded like it was going to explode and rip apart the inside! I can email you the files if you like?

Gnome freezes after suspend mode

Hi,
I am not quite sure how to proceed here, but I tried to collect as much information as possible. So when I am inactive for some minutes, my laptop goes into suspend mode. When I try to login again, the first attemp will not work (something like legitimation failed) and I have to hit ESC twice to get the login mask again. Then I am able to login, but everything except the upper gnome bar is frozen. I can hit the Super-Key and get an overview of my windows, but selecting them they appear in the foreground, but being "unclickable". Since I have driver issues with the broadcom chip, I installed the 3.11 kernel from testing, but except the direct dependancies I've not updated anything else and switched back to stable.
I can change to separate ttys (even though sometimes the login manager appears on tty2 after freeze), but I am not able to restart gnome with
pkill -HUP gnome-shell
though I can completely kill X with
pkill X
uname -a
Linux wom 3.11.0-1-ARCH #1 SMP PREEMPT Tue Sep 3 08:58:01 CEST 2013 x86_64 GNU/Linux

So I just installed the [stable] kernel and the problem still appears.

It's the same for me regarding screenlocking. My dmesg log seems to me normal. I looked into Xorg.logs and I found nothing special. Has anyone an idea which log to look at? pastie.org is somehow behaving strange so what's the official way to attach a log file?

My EMAC G4 has a very loud fan.

I recently bought my first apple machine - a used emac -
running OSX 10.5.8
But the fan is LOUD - not noisy - I mean it's sounding like an air-conditioning unit on medium and makes listening to any music uncomfortable.
I've read that if I installed OSX 10.4 then the fan would run quieter.
Is this the case?
Thanks for any help from a new apple user.
