MacBook :: All Of A Sudden Crashed - Fans Are Full Blast All The Time
Jul 1, 2014
I have a white MacBook and its three years old. It all of a sudden crashed last night and when I switched it back on the fans were running full, the time set to 1-1-2001 12:00am and there is an X through the battery sign. When I click on the battery charge symbol it says " No Batteries Available" although it clearly does as it runs without needing a charger. And then there’s the fan.
It started running at full speed (like I was playing a game or something) and it just runs like that all the time. I have restarted my computer and shut it down several times and the only problem fixed is the time. Also when the screen is shut it doesn’t go to sleep or even show signs that the lid is shut? I haven’t done anything to dislodge the sensor so I don’t know what the problem is.

My menu icons kept flashing on and off for a while. I left the computer by itself for a bit and returned to find the fans blowing at full blast and the cursor wouldn't move. So I pressed the power button to turn off the computer and restarted
My console log showed this repeated about every 30 seconds for about 30 mins
I think the icon flashing was a result of having a film dvd in an external drive like in this thread [URL]
I've ejected a film DVD that was in a Lacie external drive and verified my internal and external hard drives to check for any errors. All were ok.
I'm not too worried about the menu icons flashing but I am bother about the fans blowing like this. The fans have blown at full blast and crashed the computer about 12 times in the last 4 months when I have been away from the computer. So i'm a bit bothered about leaving the G5 alone. I haven't been able to replicate this fan issue - its random. Erasing the HD and installing Leopard doesn't seem to have stopped if from happening (I had the same problem in Tiger)
I have attached a screen capture of my Stat widget below
The slots and backside fans are always stuck at 76rpm and 51rpm. Also CPU A is normally at a high temperature than CPU B. I think the highest i've seen that temperature at has been about 75 but i don't look at it often. These stats were just when I was importing a CD into itunes fans were quietish.
I'm thinking about getting Apple to have a look at my G5 while the Applecare is still valid (it should run out in May).
Can anyone look at their Stats and see if their slot and backside speeds are stuck at similar rpms.

My mac has always been fine only getting up to about 70*c when encoding. Now it gets past that when doing nothing, and fans going full blast! Tried every mac temp. software. Looked in activity monitor, nothing major running, biggest thing is "activity monitor". I can just have it sitting on my counter, on hard surface, very hot fans full blast. Its a new MacBook White early 2009.

I just bought a new dual 2.0 ghz power mac G5 about 2 weeks ago. I set everything up and dowloaded all the updates for everything, and then about a week into using it the problem started. I left for work and when I got home that evening after the computer had been asleep all day, it sounded like the computer was taking off from a runway. It would not respond at all to the keyboard or mouse so I had to shut it down by holding the power button on the front of the unit and then start it back up. I called tech support but they had me turn the option off that puts the harddrive to sleep when possible and then turn off my screensaver. Well it was fine again for about a week and then it happened agin yesterday, not once but twice. I looked on apple discussion boards and there is alot of this happening. Well I took one guy's advice that seemed to know what he was talking about. I restarted holding the command-option-o-f keys down, then prompted the computer to reset the v-ram, and two other things he suggested to reset that I cannot remember. Then I restarted, trashed the energy saver prefs and ran a repair disk permissions task inside OSX. Well that is where I am now, and it has not done it again, but I am still trying to find out what exactly is going on here. I just spent $2000 on a machine and it appears messed up and Mac has no answer.

My step-son works for a company that uses a variety of computers in their test dept. and when they upgraded the test equipment they gave the old stuff to employees.My step-son is a dyed-in-the-wool PC guy who doesn't care for Macs so when he saw a G5 PPC sitting there he took it home and gave it to me.
It's a 2.0 GHz dual-processor with 8x AGP video. I checked it out and the only thing "wrong" with it is that someone has set up the fans, all of them, to run full-speed all the time.First, how did they most likely do that and, second, how can I return the fans to their normal operation. This can't be good for the computer and it's so loud and annoying that I'd rather use my G4.It's a great computer otherwise, I hope they didn't do something permanent that would require a new motherboard, that's not in my budget.

My G4 iBook's goes full blast when ever I open it (waking it from sleep mode) or when I turn it on. I don't remember this always happening. The fans are really loud, it bothers me. Not the end of the world, but if there is a simple solution I'd like to do it. Also the fan dies down pretty fast so I don't think its a huge deal, but if its going to lead to a big problem I want to fix it now.

Noise of fan continuously running may also be the hard disk.

I've got this weird problem with my late 07 SR 17'' MBP, after I plug in the Magsafe charger the fans start spining and in like 3 minutes they reach 6000 rpm (both of them) and stay that way until it's finishing the charge. I did the same exact tasks with my laptop charged and plugged in, and the fans stay around 2000 rpm, as opposed to when it's charging staying at full speed.

So today I opened up my MBP to clean it out and stuff (it had a ton of dust... A wall of it had built up where the fans blow out)All is fine and dandy now except for one thing. Since I don't want to open my case up for the second time today (right fan wasn't plugged in all the way first time I started it up... oops x( ) I'm asking here since everything else seems to be fine.
What I did:
Opened everything up all the way down to the heatsink.Applied correct amount of Thermal paste.plugged everything back in (right fan wasn't perfect at first, but fixed and stupidly didn't double check everything else while I was in there)
And now both fans are running at 6k (full) constantly. I tried resetting PRAM and SMC with no luck. I'm about to grab my disk 1 and run the diagnosis to see if that turns up anything.Are there any plugs that I might have accidentally not plugged in all the way or at all that would cause this? Also any other suggestions if everything is plugged in correctly?

Also, I have iStat Menu. No apps using all my CPU (Mostly <10% usage right now) and temp is mostly <40c right now. All temps have a temperature so I'm assuming all heat sensors are fine.On a great note: My computer is so much cooler now! Even before this at 6k rpm I'd get down to MAYBE 45c if I was lucky.I also have Fan Control installed and it's not having any effect

Occasionally, my Mac Pro's (8-core early 2008) fans will go to full speed after a shut down. I did the procedure of unplugging everything and letting it sit for 15 mins, and that seemed to work for a day or 2...but last night the problem was back. The only solution is to hold down the power switch for 10 seconds. I just reset PRAM -- we'll see if that has any effect.

I have a 2010 MacBook Pro, with the following specs; OSX LionIntel i7 2.8GHz (dual core)8GB RAM256GB SSD HDDIntel HD graphics..The issue that I have been having is a sudden, unexplained increase in boot-up time. Yesterday and for the past two years, my MBP took circa 15 seconds to boot up, but today it has been taking approximately 5 minutes. I have the latest software update.My hard drive space is running low; I only have 4GB of space left, could this be a contributing factor? When I switch on the laptop, it get to the picture of the Apple logo, without the spinning gear below, hangs there for approximately 4 minutes, and then eventually continues to the user log-in screen.

Brand new 2009 octo, with the 2.2x ghz CPUs. Turn it on, start NO apps. Let it sit idle. Within a few minutes the fans ramp up to FULL jet engine speed. I can't hear people on the telephone. And never stop. Let me reiterate that I am running NO apps. My load averages are in the zeros.

I've got a little problem with my iMac 24" 2.8 GHz Nvidia Geforce 8800GS 500GB. When I start it up, the fans start blowing at full speed. I checked the apple support page for support and found my problem with all the symptoms being correct. The support said I had to reset the SMC by shutting down the iMac, then removing the power cord and all the other one's, wait 15 seconds and then put the power cord and the other one's in respectively. I did this almost 10 times, but my iMac still won't stop making those annoying noises. Maybe it has to do with the SMC fancontrol app my brother installed lately.

My PCI bay fan is running at full speed no matter what. The temperature sensor reads correctly in OS X, so I don't think it's a bad sensor.
Is there any way to set the fan speed manually, say in openfirmware?
It's a 1.8 DP June '04; I've ran ASD 2.5.8 to calibrate and test the mobo, which passed.

I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.

I have a 24" mid-2009 iMac, bought in June. It's behaving oddly over the past week or so. It fails to wake on sleep on the first attempt, but always succeeds on the second. When I say fails though, I mean that it *does* wake up, but goes back to sleep again after a few seconds. The other issue happened today, when I woke it up, in a cold room, the fans started up at full speed (I assume). It sounded terrifying to me as my iMac has never got that loud - not even playing games. I restarted it and it was the same, but died down after a while.

Exactly the same issue on Macbook Air and new iMac both running Safari 5.1 and Lion 10.7.3Â
When I open Safari it does not open a page, it just shows a spinning beach ball and shortly after the fans kick in and the activity monitor shows 1 webprocess at 99 - 100% or sometimes 2 web processes at 50/50% all coming from the User. When I inspect the process it says it's "Parent Process (Safari 450)"Â
When I quit safari the web processes stay at 100% and will only stop when I quit them in activity monitor. I have reset Safari but no joy. Firefox etc works fine. The only update I ran was a 1Password update but they say it's not them.Â

Last summer my MBP 2.3 GHz C2D was heating up so much, you barely could touch it. So I decided to give it a little hardware checkup. Finding the fans completely stuffed with dust
But after a while i recognized that the fans went on high rpms (around 6000) already at startup and did not lessen anymore. I do not have any high capacity processes running and the temperatures are not just not warm buth rather chilly, so no need for high fan speed. Now I want to solve this problem as well but seemingly nothing will work.

For the past couple of weeks I've noticed that my old white macbook is running hot, and browsing has been kind of slow. I don't see anything out of the ordinary in the processes, but Heatsink A is reading -1. Should I just pull the machine apart and see if something isn't connected anymore? I installed a 7200 RPM HD a few months ago, but this problem is more recent.

the other day i wake up and open my macbook pro and immediately heard the fan making noises ive never heard it make before. i checked istat pro. the fans were going at 2000rpm. this is when i started to get concerned since i would never hear the fans at that speed before. the difference was day and night. it sounds like the one or both of the fans are hitting something. i always hear the noise when i start up or wake up from sleep and after a while (30 minutes to an hour) it usually goes away but has come back once without me turning off or putting the computer to sleep. its a refurbished less than a little more than a month ago. im hoping its just some dirt that made it through keyboard and will eventually go away because i dont want to send my machine in to get manhandled by apple repair. has anyone had something like this happen before?

My roommate just lost his data, so I realized I needed to back up. I plugged in an external hard drive (it was an internal that we put into casing bought from OWC, if that matters). I wasn't thinking about Time Machine but it displayed a message, so I said yes, backup onto the hard drive. Then while it was backing up I was just reading a document, the machine crashed. I swiveled my desk to get something and this caused the external hard drive to fall, for a second it was dangling from the USB. (I'm not sure if that's relevant but.)
I first restart (held down the power button), since nothing was happening. At that point the hard drive was making a weird rhythmic clicking sound. Then it wouldn't start up! I tried this twice. Blank gray screen. I reset the PRAM (was that a bad idea?) and when it started again, I get a folder icon with a blinking question mark, over a gray background. Then I freaked out because this was what happened to my roommate, so I haven't touched the computer since.
What could have gone wrong? What to do now? (Local help centers only open on Monday..) Is it worth it to take a train for an hour to go to an apple store right now?

So I got my mac fixed and I picked it up from apple store, when I was restoring I messed with the external as I was restoring and stopped it in the middle. So I don't have a snow leopard disk or any disk with me. If I borrowed a leopard disk could I restore? I want to restore completely from the day my computer crashed.

I have an imac 7,1 - intel core 2 duo, 2,4GHz, that is 20" from mid 2007 with an HARD DISC: Western digital : WD3200AAJS - (320GB) that died.so I bought a NEW HDD: Western digital: WD10EARX - (1TB): Caviar green series I changed step by step the HDD and reconnected everything and all went well, until I re-started the iMac. After approx. 2-3 min the HDD Fan began to increase in speed and since then I have tried everything that I found on the net and nothing worked to slow down the fans.
That is the external temp sensor is set in the same way as it was on the old HDD. I reset the SMC and the PRAM several times, actually oppened and checked all cable conections three times. I installed the SMC fan control - no difference, the HDD fan control demo version - no difference. THUS the problem is that the FANS do not stop working as if the comp is on fire. Â

My iMac seems to be a lot more noisier (a low humming noise, maybe the fans), than it was when I purchased it in a couple of months ago. When I first got it, it was the quietness and boot time which I was impressed with more than anything. Now it's noisier and boot times have doubled. I have noticed that the fans for for HD and CPU constantly spin at 1200rpm or more, with no applications open and as soon as I switch on my iMac.
