MacBook :: Overheating And Shutting Down On YouTube - Fans Not Running?
Jul 5, 2012
My Macbook's been overheating and shutting itself down the past two days, usually when on YouTube. Having installed the Fan Control system preference, I can see the fans aren't running at all. My first thought is that they might be broken, but this happened for a little while last year, too, and the fans started working again after a while. Also, it's been miserably hot in my area the past week, and I wonder if that's contributed to it, too (even though the laptop's in an air-conditioned room). Anyway, should I wait and see if the fans begin working again, take it to a repair shop (warranty's expired, so I'm not keen on that), or maybe buy a cooler pad?

Over the past few weeks my blackbook has been shutting down more and more frequently from what I can only believe is overheating. I just checked my computer upon startup with SMC fan control - it starts up at about 70 C and at about 3500 RPM. Yet, after a few minutes, the fan immediately drops down to 1100 RPM or and fluctuates between 800-1400. I try to force the fans to spin with SMC Fan control, but nothing happens. I've looked all over the web and I can't find anything definitive. I know that macbooks tend to overheat. What can I do? I'm at college and I really need to find a fix for this as soon as possible.

I'v just noticed, after installing iStat menus, two different CPU usage measurement graphs. Core 2 duo, so apparently one for each core or chipset, whatever . But the weird thing is, that sometimes, while watching movies, burning dvd etc. (sample "high usage" situation), when the CPU temp. goes around 60 celc. and fan spins at 6200 rpm, one of the "core graphs" shows nothing, like the core is shutting down (screen attached). It's annoying, because the whole system slows down, I can't do anything, and after like 5 mins it gets back to normal (after closing for example the movie). Any solution for this or should I just get used to it?

My Macbook is 1.5 years old (13in, white, 2 GHz). About two weeks ago, it would randomly shut off. It would restart fine, but shut off sooner. Sometimes, it wouldn't even restart. Now, it's at the point where when I power it on, it rarely restarts past the white apple start-up screen.
My thought is that it is overheating. Are there any more ideas? What can I do to save my macbook?

I've got an early 2005 model Power Mac G5. Bought it from a hospital and it's really clean inside. Lately it's been shutting down spontaneously without warning. I thought it might be an issue with overheating, but I'm not that familiar with normal heat levels for a CPU. I installed iStat nano and checked the temperatures. I took a screen shot of the widget. Temperatures are in Fahrenheit. Can anyone tell me if I'm on the right track? What do I need to do to solve this problem?

I don't know if it is a fan or a drive that starts up and runs really fast and loud, then the computer shuts off. I always thought it was the fan, but now am not sure. I have moved it to a place where it is exposed to more air, but that has not seemed to help. Does anyone have an idea or solution to this problem? The nearest Mac dealer is about 80 miles away, so if I can fix this on my own, I would like to try.

I've googled to see if I can find a solution to this but not had any luck - wonder if you could help. My Mac Mini is 1.5Ghz PowerPc G4, 512Mb RAM, running Mac OS X Version 10.5.8. I bought it second hand a couple of years ago and in the past while it's really been playing up a bit. It first started overheating and shutting down when I was doing really resource intensive stuff - for example, opening a large amount of RAW image files. However, it's now started taking to shutting down when I'm doing normal browsing, using Spotify etc The machine also tends to hang a lot, and I can't really stream videos very well either. The vents at the back of the Mac definitely aren't blocked and there's plenty of space around the machine to let the air circulate.

How do I turn on the fans on my iMac to keep it from overheating? I used to be able to turn them on when I plugged in the computer and turned the computer on simultaneously but that stopped working.

my MacBook runs like ****. It's constantly hot (CPU is always above 70*C), it can't get through one youtube video with out stuttering and overheating, it can't run my external sound card (Audio 4 DJ) in conjunction with anything else, and it can't play AVI files without freezing and bugging out. It's a 2nd gen Black MacBook with 2ghz processors, 2 gb of ram, and an upgraded WD 320 GB HD. Is this thing about to take a dump on me? Is the motherboard on its way out? Is there any chance of fixing this thing? It seems the only thing my computer is good for theses days is doing light browsing on the internet. (read light browsing = no flash and no html5.)

I have brought a new iMac 27'' the i5 model. I have noticed that the fans never change speed no matter how hot my processor gets ? Is this normal ? I have ran prime 95 and istat pro to check the temps and fan speeds. Nothing changes apart from the temperature.

I have a G5 dual 2gig and in idle mode it seems to a be slightly overheating as my fans start to blow harder and I get my mouse sticking I am running the latest version of Tiger with 3.5gigs of ram I did post in the IDvD, Logic Pro, and the Final cut pro forums the impact of an upgrade of 8gig of ram on my system whether my apps would run better and the system as a whole.
But I have not been able to get any feed back on this that was clear and I was asked to try here on this forum so here I am. I deeply love my G5 and what it can do I am just wondering if it is working at its most optimum I do regularly do my house keeping i.e. repairing permission and occasionally using Tech tool Pro to look over the system but nothing out of the ordinary jumps out. I have a screen shot of my activity monitor and cpu monitor but I do not know how to attach it.

Since then, I feel like my Macbook is overheating when even it isn't using heavy apps.
Right now, using just Safari and the Mail on, CPU and Heat Sink A is nearly 60.
Can it be from the new components ? I upgraded the Memory and the Hard drive.

First of all, let me give you a rundown on everything I have done: I have reset SMC. I have reset PRAM. I have disabled Java in all browsers, and I have deleted Java. I have erased disk completely, taken it to the Apple store and have OS reinstalled. I have repaired the disk. I have repaired disk permissions, and I discovered Java had a value of 80, should be 0. (This caused me to disable most Java programs.) I have verified the disk and disk permissions.
After the restore, I have only reinstalled a few programs: (Upon reaching this problem again, I deleted some programs):
Opera Browser - Deleted, did not allow me to disable Java.
Caffeine - Deleted, not well known.
StarCraft II - By Blizzard Entertainment, too uptight to create this kind of problem.
Komodo Edit - Deleted
Skype
LogMeInHamachi - Deleted
Files:
A folder with some HTML and CSS and a few pictures - Deleted
A screenshot of my computer on my desktop.
I have no music in iTunes. Nothing. For example, right now, I am listening to YouTube and typing this. A message pops up with message: Are you sure you want to shut down: Sleep Restart Cancel Shutdown (Shutdown is blue).

Both of my fans are running at the max 6200 RPM and have been for well over an hour. My CPU is over 65% idle, and none of my processes are over 20%. My HD Temp is 38 degrees and my CPU temp is 72 degrees. I don't think my fans should be running this high considering the computer is doing so little work.

I own a Macbook pro 17" core duo 3.06Ghz. I am very happy with the machine, but since a few months the fan's are louder and on much more often then ever before. (the first half year it was always silent) I remember there was some reset for this.

Like 3 days ago I shut down my macbook pro normally. I closed the lid and I noticed that the sleep indicator light was on. I opened the lid and the light went off. I closed the lid again and the light went on again. I got closer to the computer and the fans and drives inside were still running. The only thing I did was to hold the power button down until it shut. This has happened to me 3 times already. I'm kind of worried because I got the computer 2 weeks ago and I'm really happy with it. My computer is a 2010 13' Macbook Pro running Snow Leopard, not sure what version it is.

I've just bought a second hand macbook pro, the battery is dead which is easy to replace i guess but worse the fans are running constantly at around 6000rpm.I've tried resetting the smc and pram but that hasn't helped.I tried to run the hardware diagnosis but that freezes when it gets up to testing the logic board and i have to pull the power adapter to turn machine off.I only have the second of the two install dvds and machine is running os x 10.5.8

So my macbook is running slow lately, and it keeps on automatically shutting down applications. E.g. skype. Could this be a trojan?

I shutdown my mac air because it was running slow. When I restarted it the apple logo and the spinner just kept spinning. I shut it down overnight and now when I restart it acts as if it is starting then a grey screen rolls down and a dialogue box says I need to restart. It is a 2010 macbook air.

Twice my macbook pro has shut down on me spontaneously. I recently got the logic board replaced. What could this mean? What do I need to do differently?

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.

My fans have always been running at 2000 RPMs. I downloaded an app from the mac app store which caused the CPU to overheat, and in order to control this I read that it was wise to download smcFanControl. I downloaded this and added 2 settings, 2.4K RPMs and 2.8K RPMs. This worked to cool down my laptop, and once I realized that my CPU is at 36 degrees Celsius, I set the fans back to the default settings at 2000 RPMs. Now, my fans are constantly running at this speed according to smcFanControl and iStat. My core is cool, not even warm, yet all I can hear are the fans spinning fast to push hot air out of it, when there is none (I've put my ear to it to hear and feel the heat, there is no heat coming out).
I've had this laptop for less than 24 hours, it's a:
15' Macbook Pro late 2011
Intel Core i7 Quad Core 2.4gHz
7200RPM 750GB HDD
Also, this was not occurring prior to downloading smcFanControl (I've turned it off, deleted it, nothing works) - Even after turning off the laptop, the fans stopped, automatically after turning the laptop on the fans came back on. Some extra information: When I put my ear to the bottom of the laptop, it sounds like a vibration.

I was just wondering if it's okay to run the MacBook with the max fan speed (6200RPM) at all times? It's really hot nowadays and my MacBook runs at about 60 degrees Celsius idle. If I run a few CPU intensive apps, the temperature usually rises to 70-80 degrees. This is with the fan running at max speed. So what I want to ask is, will it be okay to keep the fans running at max speed at all times? I'm going to get a notebook cooler soon so that should help with lowering the temperatures a little lower.

It's the 2008 model MacBook Pro with the 9600m gt 512 card.
So, I just noticed that when I have my MacBook Pro in High Performance mode it emits an high pitched noise when the fans are running around 6.2k RPM and the CPU and GPU is around 63c. The noise follows the speed of fans, and at idle the noise is gone.
I have uploaded a video of it on youtube here: http://www.youtube.com/watch?v=HioRgTNpNRA

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.

I have a new macbook, see stats below.
Up till last week everything was fine, I could run 'Second Life', photoshop, email, a browser, download stuff, play Itunes AND watch a movie all at once without any trouble.
But recently the computer has gone a bit weird.
It started getting very hot, much slower and turning itself off.
