Won't boot, loud fan noise after kernel panic?
So I got that kernel panic screen yesterday, turned it off, and now when I try to turn it on, the screen remains black and the fan comes on really loud. After about 30 seconds it stops. I tried inserting the original disc, but it won't go in the whole way. I've been using the laptop pretty heavily lately, but haven't damaged it that I know of. The battery has been dead for a while now - relying completely on the adapter.
Any suggestions would be appreciated!
I have a similar problem. My son was using the computer at the time so I don't know if he saw the kernel panic. The screen is black and the computer won't boot. The fan runs loudly and doesn't stop. The battery is relatively new, about six months old. I've tried plugging in an external monitor but there's no signal.
I have tried two different power adapters. One has showed orange and quickly went to green, then the light went out. The second adapter is third party but it seems to be getting power to the Mac. To complicate matters further, there is a DVD stuck in the drive. If the Mac is dead, I'd like to at least get the DVD out of the drive!
Thanks in advance for any ideas.

Mac Pro loud fan noise after 2-3 hours
Hi. I bought a Mac Pro quad 2,66 with 5 Gb ram for about a year ago. Everything works well, but after 2-3 hours the Exhaust and CPU fan starts to raise and when checking iStat it stays at about 3000 rmp for Exhaust and CPU. The noise is bad...This happens even if the Mac is not in use (any programs running) The temperature inside the Mac is low - about 30 degrees (Celcius) and the fans do not slow down until i restart the Mac. I have tried the Reset of the SMC. There is no difference after resetting the SMC....
Any suggestions??I have been dealing with a Mac Pro for the past 6 months in my sound studio having a constant vacuum from the fan. I assumed this was normal and a purchasing oversight I made. It was far from silent, infact it was so loud it sounded (on recordings) like a car was constantly in the room idling. Very annoying.
I took apart the mac pro thinking there would be maybe dust (as people suggested) in my video card - as that appeared to be where the sound was coming from. I removed the card, and there wasn't really a build up of dust.
I did however put the card back into a slot (it was on the bottom slot closest to the ram - maybe it couldn't breath?) and turned it back on and for the first time since October 08 I have the computer I paid for and not an oversized noise box.
So there is obviously something dodgy about this ATI card Apple. Its actually really quite annoying and dealing with a nuscense noise for 6 months on a computer you drop thousands and thousands for is just ********. -
27" I Mac, constant loud fan noise after replacing hard drive. Help
Having constant problems with noise since replacing my HD, which failed miserably. Best Buy installed a 1T Seagate, sounded like airplanes taking off, took it back and they installed a Western Digital Cavair Green 1T. Noise starts out soft, gets increasingly loud. Can hear it running in another room. Hate this- any suggestions. I've already done the reset thing twice, no help.
Is it a late '09? Is the noise the fan? And was your first HD a Seagate as well, with the correct temp sensor cable? Here's an explanation. Surely Best Buy would know that but maybe not. A 1TB Seagate is listed as working in the article, but it has to be a HD with the temp sensor inside, not attached to the outside of the drive.

Keyboard creating loud fan noise after coffee spill
After a coffee spill my keyboard has been creating my fans to run very loudly. The temp. is still pretty normal at 40C. When I have the computer on and disconnect the keyboard, the fans return to normal. I've tried cleaning everything inside and removing the fans and putting them back in. Is there anything else I can do? Thank you.
Go to the Apple Store after you have made an appointment with the Genius bar. Liquids are the kiss of death to keyboards. Sorry to give the bad news.

Loud fan noise after re-install
After I had to re-install - I am able to hear my fan all the time. The support technician told me it will go away after awhile.... but how long is 'a while' - it's been a good three weeks.

Thanks - now that I have the Console and Activity Monitor... what should I be looking for?
In the Activity Monitor, I have bunch of stuff but they are all 0.0 in the CPU column....

Thanks
If you click on the CPU tab, it will "flip" the column from max usage to min usage. Be sure the top item is the one using the most CPU clicks.
If there is nothing unusual there (on my computers, Safari takes the most CPU time, about 10%.
You can also click on the items on the lower graphic area to see a short history of things.
If the noise is the fan, you are looking for a process that is taking up many CPU cycles, causing overheating. If nothing is there, it may be a bad heat sensor or something making your fan run at top speed all the time. It could also be that a fan bearing is going bad.
The console would also show up any errant process. If you click Console Messages and look at the recent ones, you would see if something were very wrong.
The other thing is to note if your computer is getting hot, meaning that the fan is really needed.
If nothing shows up, you may need to take the computer into an Apple store for service, since if the fan stops working, you will certainly overheat the computer and possible damage some silicon. -
I left my office only to return to find that my Mac mini had turned off. I tried to turn it on, the light comes on, and the fan comes on (very loud). But that is it.
I have had it less than a year with no trouble.
Anyway I have tried resetting the PRAM. Any ideas?
Thanks.Reset the SMC, as per > Resetting the System Management Controller
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
If that does not resolve the problem..?
Run the Extended Hardware Test, as per > Using Apple Hardware Test
If that does not work or you encounter a hardware problem, contact your local Apple Store or AASP using > Apple - Find Locations and have the Mac Mini checked out. -
Mac Pro will not boot, constant loud fan noise and nothing else
hello,
earlier tonight,i put my mac pro on sleep, then later on, when i wanted to take it off sleep and use it, it made the loud fan noise, which it always does but goes away, but this time it the fan wount slow down and the loud noise stays and i dont see anything on the screen. im guessing the fan noise is the ATI x1900 card...
any help please..i just bought it 2 months ago...Hi, here are the steps I would go through. I would unplug the Mac Pro completely from everything and look at the video card's fan intake to make sure it isn't plugged and just make sure everything "looks" correct. I would then plug the machine back into one monitor/keyboard/mouse (leave all the other peripherals disconnected. Once that is done push the power button. Does anything happen? If not then if you have another mac and an external hard drive, make a copy of the OS on the drive and see if you can get the Mac Pro to boot off that drive. If the video card doesn't work then it will not show anything when booting off an external drive. If the external boot does work then I would suspect that you have a bad hard drive (or it crashed). At that point I hope you have a back up of all your data and such.
Mind you these are steps I would go through. What a nightmare. One other thing to check, make sure your monitor didn't die.

Lenovo G560 - Issue with won't boot and black screen after HDD upgrade
Lenovo G560 - Issue with won't boot and black screen after HDD upgrade.
What happen: My laptop was working fine, no blue screen issue, no funny business at all. I bought a new SSD Intel 120 GB and thought it would be a good idea to replace the HDD. I shutdown and disconnected the power adapter, waited a couple of minutes and removed the battery. I opened up the back case and replaced the HDD. And put all the screws back and put the battery back in.
Problem: The very first time I turned the power on, nothing happens besides a black screen. I pressed the dvd drive it works and opens up and closes. I waited for about 30 mins and still has blac screen. When I mean black screen, no bios menu, no logo, just a black screen with the fan sound on.
I have tried these:
1. Unplugged everything - battery, adapter, and pressed the power on button for about 60 seconds, nothing, the laptop turns on with the LED display on for both on and battery LED's. But nothing but black screen, no sound of windows loading just the fan and black screen.
2. I tried putting back my old 2.5" and nothing but black screen.
Thoughts and suggestions?
Solved!

My 2008 Macbook Pro makes a loud fan noise.
Hello -
I bought my 15" macbook pro back in October 2008. I was very happy with my purchase due to the machine's performance. But over the past year I have noticed an increase in the fan noise. It almost sounds like it's hitting against something at a very high speed, hense this irregular fan noise. The noise also increases drastically when I am working on Photoshop or InDesign. I also partitioned my hard-drive to hold windows so I can work on AutoCad.....noise increases also as I work on my machine.
Why is this happening? Could this loud fan noise damage any internal component to the machine? Should I bring it in to Apple immediately?
Thank you!Some of the applications that you mention are somewhat CPU intensive which creates heat and results in fan speed increase and hence additional noise (to state the obvious). However if you are experiencing excessive noise when CPU loads are modest it could be that your fans are failing as all mechanical devices eventually will or you may have 'schmutz' inside that is the cause of the unwanted noise.
I suggest you open the MBP and see if there is any dust in the fans that may very well be affecting their performance. After 4 years, this is not an uncommon situation and it could be the solution to the problem.
If not, then you may consider getting replacements from iFixit or Powerbook Medic and replace them your self. It is not rocket science in this instance. If you suffer from chronic fingerfumbilitis, then have the Apple store do it for you.

Loud fan noise on mountain lion, Mac Pro early 2008
Hi there,
I've recently installed mountain lion 10.8.5 lon my Mac Pro , early 2008, 2,8 GHz, 24 gb ram, 2x ATI Radeon 2800 XT.
To give it a clean shot i clean installed it on a sep. Partition, no upgrade from my previous Snow Leopard.
The Machine usually works quiet, i've measured via Isat Menu:
exhaust fan: 681 rpm
HD/expansion: 1100 rpm
After running Mointain Lion, latest update version, i get a much louder fan noise than in snow leopard:
exhaust fan: 845-950 rpm
HD/expansion: 1500 - 1800 rpm
The activity monitor shows no significant CPU usage, only the kernal has over 90 threads constantly running.
I've heard that this is a known issue but it's never been resolved. SMC and PRAM reset did not work at all.
when i go back to snow leopard everything gets back to normal. Yosemite is even harder on fan noise than mountain lion
so i've rolled back to mountain lion.
Any idea ?
dezzono one here with the same problem on an early 2008 Mac Pro ?

Added Ram to Mac Mini & Now There is Loud Fan Noise
Hi everyone,
Today I bought a Mac Mini Core Solo. I brought it home and opened it to add an additional 1gig of ram. I now have 1 stick with 1GIG and 1 stick with 256mb of ram inside of it. After adding the additional ram I closed the case and turned the power on. It picked up the new ram but it is now making a really loud fan noise. I'm nervous that something has gone awry. Any suggestions for as to what is wrong? Did i do a big bad?
I'd appreciate any advice!Sounds like a connector to the fan was pulled loose when you dismantaled the mini to get at the memory slots.
See the pictures here...

Open her up and check that the wires from the fan a re seated onto the motherboard correctly. -
Macbook pro retina start to make loud fan noise and work slow
I bought macbook pro retina display less than one years ago. For some reason my macbook pro has been making loud fan noise for about five mounth. Whenever macbook pro makes the noise, all the programs start to run slow. Typing, opening safari, and etc takes forever. It takes 20min to 40min for the noise to stop. At first, the macbook pro made noise once or twice in a day, but now it's making the noise frequently; It happens every 2-3 hours. It got to the point where it start to annoying me. Is there a way for me to fix this issue? If not, can I use one year warrenty to fix this problem? Thank you.
If your Mac works slowly when fans turn on, it's quite possible that there's a process which is eating the CPU and/or RAM.
Open Activity Monitor (in /Applications/Utilities), select "All Processes" above "Show" (in the toolbar) and then, order the processes by CPU usage. Do you see any process which is consuming more CPU or RAM? If so, tell us the name.
Additionally, you can reset the SMC > http://support.apple.com/kb/HT3964 -
Hi there,
I have a Imac G5 Rev2 and I read a lot of topics about loud fan noise. I bought an Imac about 4 months ago and the fan noise is a bit louder than when I just got it. What do all the users mean by "loud"? It is only once, when I was running the hardware test, that I heard my Imac did the "airplane" (very loud) fan noise. When I am using applications using a lot of CPU, I hear a louder fan noise but not the "airplane" noise.
Then what is the most reliable program to check the temperature of the iMac G5?
Which range of temperature is normal for the iMac?
Thx in advance for ya replies....I have a Rev b just like you and light use the temp of the cpu is 65-68º C while the hard drive is about 53º C. This is the temp as I am using two browsers, with iTunes and MS word open and running.
For a temp program you can try Temperature Monitor at this link:
http://www.bresink.de/osx/TemperatureMonitor.html
You can also try the very handy iStat Pro Widget (Of which the temps I gave you above came from). It has a lot of very useful data, from CPU to Memory usage, from CPU to Hard Drive temps---and even the speed of all three fans. You can find that here:
http://www.apple.com/downloads/dashboard/status/istatpro.html
Hope this helps. -

I had the same problem, one of my fans was making a loud noise even when my computer was just idling. It can occur because you dropped the computer, thus damaging one of the fans, or the fan broke down partially. I took mine to the Apple genius bar and they ordered a new fan for me and installed it in under a week (all covered by warranty). This is likely a hardware and not software issue, the only way for a fix is taking it to a genius bar. -
Updated to Mavericks and loud fan noise
Just done a clean install of Mac OS X Mavericks, updated fine, everything went well.
however most of the time, my macbook pro fan noise would go really loud for 5-10mins even in idle or if im on the internet just browsing.
this has not happened ever on mountain lion.
its really weird.
Does anybody know how to fix this? or is this a bug and would i have to wait for a software update?Hello all,
I am having the same issue, constant loud fan noise in my Mac book pro. Below are the specs:
"MacBook Pro
13-inch, Mid 2010
Processor 2,4 GHz Intel Core 2 Duo
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 320M 256 MB
Software OS X 10.9 (13A603)"
And CPU is 90% idle.
I tried to reset the SMC using the steps:
1. Shut down the computer.
2. Plug your Mac in, if not already plugged in.
3. Press (left side) Shift-Control-Option & the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.
Inaddition, i have reinstalled OS and reset PRAM memory but the problem still exists.
It really feels annoying with the fan sound. Could someone give a fix.
