Macbook Pro 4.1 Fans Running Constantly
Apr 21, 2012
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

I need the thoughts and advice from your seasoned Mac people - I have 2 MBP's - 1 15" aluminum, one last years model 17" Unibody (with Black around screen). The 15 has run great since day one. The 17" was ok, but now is locking up and causing me to reboot, fans seem to run on high all the time, and it is very slow to react while using the OS, it gets worse until it locks up. I have upgrade to Snow Leopard thinking that that might fix it, but it has not.
When I got it, I restored from the back up of my 15" using carbon copy cloner. I only imported users and data such as pictures and music. Do you guys think that this is a hardware issue or a or should I back all my stuff up and then blow everything away and reinstall from the ground up with a fresh SL install?
When I called apple they tried to sell me apple care and told me that it was out of the full warranty and if I send it I would to pay for what was not under warranty. SO I am hoping that someone has seen this and has a fix that I can do without having to take it in.

My PowerMac's (G5 Dual 1.8GHz procs) fans seem to run at a solid 4k rpm's regardless of what I'm doing, even with CPU usage set to low. I've taken the whole machine apart, cleaning it with canned air and such, but the problem just won't leave me be. The air coming out of the machine is ice cold, and the temperature readings I'm getting are about 86 degrees F for the CPU's and 70 for the HDD, so I'm not sure what gives.. Slot and Backside fans are running at 255 rpm, but the others are all 4k.

What is wrong with this picture? The fans are running out of control constantly. This machine is sooo loud. The power supply was just replaced, which did little/nothing. Reset all ram/etc.

I noticed that my GPUs fans (either ATI 3870HD or 4870) in my MP 1,1 are considerably louder nonewithstanding nothing CPU/ GPU taxing is running. Anyone else noticed this? Are the GPU drivers not finished yet or is it due SL keeping them under load for Open CL/ Grand Central?

Both my left and right fans are constantly running at 2000 rpm. They have not done this before, but over the last week I have noticed this issue. Heat does not seem to be an issue in triggering the fans. I'm so confused on why they're are constantly on now.No CPU hogging processes or high temperatures.

My fans are constantly going on my g4 powerbook and the noise drives me nuts. I do all sorts of work - graphics (CS2), music recording, multimedia... but even when I am just not doing anything intensive the fans are on.
The fans are at full speed now and the temp reads 37C / 98F. I've used an icurve since I got the machine.I've put up with this noisy sound for a couple years now. One person said I need to clean the air vents, like dust is causing the noise. Does anyone know about this?
its a g4 titanium powerbook 867 mhz 768 RAM (ancient I know but it still works!)

I've had an iMac for just about a year and over time I guess I just didn't notice but the machine always ran very quietly. At the same time the back of the computer would heat up so bad that it would nearly burn my hand if I left it there. Well last week I decided to upgrade to Lion from Snow Leopard and when I did the install failed and froze up the hard drive. I took the computer in to the apple store and they determined that it had to have a new hard drive installed because the old one (only a year old) had a physical malfunction (was broke). So anyway I have my iMac back and get it started up, backed up from time machine, and then finally get Lion istalled - and now all of the sudden I notice that the fans in the computer are CONSTANTLY blowing - I can hear them spinning and can hear the air venting out of the back of the computer - and the computer is STILL really hot on the backside of the screen. Â
So now I am wondering if the originial problem was the computer heating up and if that may have broken the otherwise good hard drive? Also now that I have a new hard drive - should I be concerned about the fans being on ALL the time? I mean they never go off. Even when I leave the computer for hours and come back to it and the screen is asleep the fans are STILL buzzing away at top speed. Here is the stats on the computer at the time that I'm typing this note - there are no other programs running than Firefox and Mail. Also - I don't know what the optical drive is exaclty - but if it's the DVD drive (superdrive) - there is nothing in the DVD disc driveÂ

My parents have an older 20-inch white Intel iMac that has run great through the years. But about a week ago it just started spinning the CPU fans up to 3500-4000 RPMs and it won't bring them back down. Istat shows that the CPU temp is around 90 degrees and the computer remains cool to the touch.
So it isn't overheating. My parents keep it off most of the time because they don't want to ruin it, but they're planning on using it in their business they're trying to start up. We've done some web searches and nothing seems to fix it.

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.

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.

For a couple of days the fan of my (15" late 2011) MacBook Pro has been constantly running and the Mac has become sluggish. The CPU temperature is 156 °F. It seems that the problem would be caused by "coreservicesd" process taking a huge percentage (57%) of the Mac RAM.
I am running OS X 10.9.3 with 8 Go. RAM and 500 Go. HD

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.

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?

I've just purchased a new Macbook. I'm very happy with it aside from the fan noise, which seems a little loud to me. Now, before I bring it into the Apple Store to have it looked at I just want to check and see if maybe I'm just being overly picky. I downloaded iStat, based on some Google searching I did on the subject and my fans are running around 2000 rpm, which I understand is normal. But in my apartment, which is admittedly quiet, I can hear my fan running constantly. It isn't extremely loud, but it isn't totally quiet either. I'm just wondering what level of noise I should reasonably expect out of my Macbook.

The fan is almost constantly running, it shouldn't be. The Activity monitor at the moment is showing that 45% of CPU is idle. About a third of my drive is free. I have 500 Gb of SSD, so there are no moving disk heads. The screen is turned up to a level I want to work with. I am running the regular stuff -- Word, Firefox, Mail and other Apple apps, all usual stuff. The MBP sits on a clear glass desk so heat can disburse through the glass, but the fan is still running. The MBP is about two years old. Lion.

I have a 13" MacBook Pro Mid 2012 model. Specs: Processor 2.9 GHz Intel Core i7, Memory 8 GB 1600 MHz DDR3, Graphics Intel HD Graphics 4000 1024 MB, Software OS X 10.9.2 (13C64). A couple months ago I went to turn on my computer and I had a blinking folder with a question mark. I diagnosed the problem as a burned out SATA cable. I looked up the serial number of the cable I needed to order, ordered it, and in a couple weeks it arrived. After installing the new cable, I turned on my computer, and voila, no more blinking folder.
However, I noticed that the fan was really loud. Once logged in, I noticed the displays were laggy, and all video I tried to watch was very choppy. I decided to download iStat menus to see what was going on with my computer. Once I checked it, it showed that the cpu was 100% clogged up with 0% on idle. But the crazy part is that 89% of the CPU's tasks showed up as system, and under system, mainly kernal_task.
I restarted my computer, resetted the PRAM (which every once in a while would work regarding the clogged CPU but never the fan), but nothing has worked. Before this problem I was editing video projects for my broadcasting class on Premiere Pro with minor lag spikes. Now, I cannot even render a 5 second clip. I was reading somewhere that my heat sensor may be out, causing the fan to run, but I didnt know if that causes my CPU to clog up...

So I got my macbook pro yesterday and I've been doing some basic stuff on it. While I was installing World of Warcraft, the computer jumped up about 101 degrees celcius. I know I shouldn't trust istat pro 100% but still, my fans are running super loud and the computer is very hot to touch. I'm not running any heavy programs or doing any gaming. I had Aol Instant Messenger on, and WoW instaling in the background. I'd like to also add that when opening various programs I get the spinning beachball very often.

So I know there are a few other discussions regarding this subject but none of them are providing me with the info I'm looking for. I am looking to get a few responses on other MacBook Unibody's (Pros welcome too) temperatures when running intense programs (games, video conversion, etc.).
So here's why I am concerned. When running VisualHub in particular, my fans and temp go up absurdly. According to iStat, my fans are over 6000 rpm and my CPU temp hit 92c the other day. I shut it down bc I was having visions of my MB melting in front of me. I have even gone as far as propping up the back to allow for more air flow but that hasn't made any difference as long as I use pretty much any video conversion apps. Games (like Spore) make it hot, but not like this
I can find links to the previous MacBooks temps (which I had and this was never a problem) but nothing on the Unibody's. So please everyone, do share. Please include what apps you were running or if your MB's ever shut down from overheating.

A lot of times, when I close the flash intense web sites, my fans won't stop running until I go into activity monitor and force quit flash. This is very irritating and kills my battery life. I feel like I am constantly playing the sims 3 even if I am not doing anything. Also, are there varying levels of how much flash you're using? For example, if you're on youtube is that just as bad as being on macrumors and looking at flash based ad banners?
