17" MacBook Pro fan runs almost constantly

Fan runs way more than it use to and the screen becomes pixalated when waking up from screen saver or switching between desktops. The fan seems to run when searching the internet. Is the video card going out possibly?

Very real possibility.

Try a SMC reset:

My MacBook Pro fan runs while sleeping

My MacBook Pro fan runs constantly, even while sleeping.
The problem started about 2-3 months ago, but was pretty rare. When I noticed the problem, I would restart the computer and it would stop for 1-2 weeks. More recently it has become more constant, and now it always has the fan running when it's sleeping.
Any ideas on what I should do? Thanks!

Mine too. If you're worried you might like to try a laptop cooler like one of these:

Not sure how well they'd work on a Macbook as there aren't any vents on the underside but it couldn't hurt and they're quite cheep.

HP Pavilion dv6 2122eo fan running almost constantly

On my now 12 month old HP dv5 2122eo running windows 7 64-bit home edition, the fan runs almost constantly, and has done so since purchase, even without any load on the pc.
Installed programme Core Temp to see temperatures, and the fan runs even at a temp. of 41C. Bios has a function to disable fan from running all the time, but even after disabling this in Bios, the fan still runs almost constantly. Would be grateful for any help/suggestions. This seems to be a problem for this pc when searching for solutions on the Web.

Andrew,
You can't control the fan speed/function directly on HP laptops. If you haven't updated the BIOS then try that. Also, here's some other stuff to try.

MacBook Pro fans running constantly?

I have had a MacBook Pro (2011) running OS X Lion then OS X Mountain Lion since last August. For the past couple of months, I've had a problem with the fans on the laptop. I made my first trip to the Genius Bar because the fans seemed like they weren't even working. The fans got extremely loud, making strange buzzing / humming noises, and the laptop got very hot. Apple replaced the fans free-of-charge, and I was out of there. Not one week later, the fans started up again with a new problem. When the fans started going, and the laptop became very hot, the screen would shut itself off at random times. So for about 3-5 seconds, the keyboard / display would shut off, with the laptop still up and running (I could still hear the fans.) I went back to the Apple Store last week to get it fixed. They kept it for 3 days to run a full diagnostic, and they discovered... nothing. The paper they gave back stated "No Trouble Found" and I went home without a solution. I've been looking up my problem, and it seems a lot of people have it. So I checked out the Activity Monitor, to see what came up... I would post the numbers on here, but they're rapidly changing... What does that mean? My friend and I both got our MacBook Pros at the same time, and his has no problems, so I compared what we both used them for. He mostly uses his at home for photo editing and Safari. I use mine all-day, every day for school work. So am I overusing the laptop? Also, when I charge the laptop, I don't shut it down, I just close the lid and plug it in... I actually rarely shut down my laptop altogether. Can this be the problem? Sorry I'm writing so much, but this problem has become really annoying, and I want it to be fixed before school starts in a few days. I'm pretty much writing every possible reason that has come to mind why this has been happening...
Please answer, ASAP

plane928,
have you tried resetting your MacBook Pro’s System Management Controller?

Macbook pro fan running slow

macbook pro fan is running slow and hot. it fluctuates between 212 and 375 rpms. heat rises up to 104c. do i need to replace the fan?

Before I suggest advice, I urge you to keep your machine under 160F at all times. I don't want to sound like an alarmist, but you can seriously damage your machine with that kind of use. Some solders melt at 225F, weaken at 190F.
You may have to replace the fan - or you may need to clean the inside of your machine and fan. It's hard to tell without inspecting your machine.
Or you may find that you need to get a different browser, and become more aware of temperature; laptop machines are much more sensitive to termperature issues than desktop Macs. Some day, you'll thank me for that advice.

Mainstage 2.1 makes my Macbook Pro fans run full bore.

Upgraded to V. 2.1 and Snow Leopard. Now my Macbook Pro fan kicks in at full blast whenever I play any patches or run backing tracks. Cpu hit looks low and memory usage is average. This never happened before. Any ideas as to what's happening?

My MBP fans have always run at full capacity when using MS 1, 2 or 2.1. They start out running normally but then start to rev up after a couple of minutes. You could try running some fan control software to manually adjust your fan thresholds but ultimately, does it really matter if the fans are running hard? Seems to me that they're running hard because they need to....MS is still very hard on system resources even if the meters say otherwise. It's the only app I run that causes the fans to run flat-out.

MacBook Pro Fans Running Fast

My mom's 2007 17" MacBook Pro keeps running its fans. Both fans run at 3400RPM minimum when it is awake. There is no fan-controlling utility installed. Is it normal for them to be running that fast? Also, the temperature (147˚F) seems a bit high.

Yeah, only running Mail and stuff. Actually, 3500RPM is my iMac's maximum fan speed.
I'll try the SMC reset.

Macbook Pro fan running constantly and CPU running slow

So, I have a Macbook Pro 2010 2.3 i7 that has started running really slow and the fan is running constantly.
In activity monitor it shows a kernel_task running constantly at around or above 200%.
I have tried all the regular tasks. PRam reset, SMC reset and nothing seems to fix it.
I have also tried a system reinstall to no avail.
Maybe I'm on the wrong track, but from what I have read, the kernel_task might be trying to slow my CPU down because it thinks it is being overworked?
Maybe the fans are also being activated because it thinks the computer is too hot?
Anyway, if anyone has any idea as to what I can do to figure out what is going on, let me know. Thanks

Why is my Macbook Pro fan running constantly?

I have a question as to why my MacBook Pro 15" fan is running constantly? Can anyone give advice? Thank you!

Welcome to the Apple Support Communities
First, try a SMC reset > http://support.apple.com/kb/HT3964

MacBook Pro fan running constantly

My 3 month old MBP's fan started running constantly a couple days ago, even when I close the lid. My usage is about 90% internet - no CPU intensive games or really anything else.
This happened about the same time my two small children were trying to play with the computer - they had gotten into the Guest account and somehow the computer was locked, so I did a hard power off. Since then (roughly) this fan problem has been present.
I can't find any software settings that would cause the fan to run constantly. Any suggestions? The machine is running very smoothly overall, and has been a bit cooler on my lap (as one would expect I suppose). But it's annoyingly loud and I'm worried the fan will die from overuse.
Any suggestions?

Just putting the Macbook Pro Retina to Sleep by going the Apple Menu command did the trick. So another thanks for the question and Ralph's pointer to Apple's Knowledge Base article http://support.apple.com/kb/HT3964
And let me say what a bizarre OS or fan glitch that, I guess AS OF DEC 21, 2013, still UNFIXED BY APPLE?
Like Jodi, my MBP is, hmmnnn...3 - 4 months old. And her post was over a year and a half ago. Also, bizarre that Apple has a Knowledge Base article dated from Oct. 2012 so it's clearly known about it for x amount of users...
Even if they solved it in Mavericks, they should still patch and support OS 10.8

MacBook Pro fan running constantly with no utilization

Just got my boss's MacBook Pro (Retina, Mid 2012) model back from Apple after a GPU related repair (which appears resolved). They replaced logic board amongst other things.
As soon as I turn it on I hear the fan, quietly running. If I close the lid, it runs for about 20 seconds then stops. This is not loud; they are not running full blast (that is a much different sound). But I can hear it in a quiet room. Owner of the laptop was complaining about fan noise before; I assumed he was stressing the CPU but now I can see what he was complaining about.
Activity Monitor (with 'All Processes' selected), sorted by CPU, shows nothing running more than 1-2%, and 'Idle' at the bottom is showing about 99.65%. So there are no runaway processes. The room (ambient temp) is about 66F (not overly hot). The laptop is on a tile counter - no obstacles to airflow. Same issue occurs on battery and wall power. Over a several hour period, I never hear the fan stop.
I did an SMC reset (ctrl-opt-shift-Power) and this seems to have no effect (this seems to be the magic bullet for most of these issues, after tracking down runaway processes).
So my question is - does anyone know what the design is - could it be that the fans are designed to run all the time on this model, but they are (supposed to be) super quiet and not audible at low RPM, and maybe these fans have been become noisy, therefore I'm hearing it? Was this a specific design issue for this model of MacBook pro (with NVidia GPU)?

Update. I downloaded a nice free program called "Macs Fan Control" from MacUpdate. It shows me that I have two fans "Left Side" and "Right Side" and they are both running at the minimum RPM; the window shows Min RPMs as 2160 and 2000 (left/right), and the 'current' is 2161/2005 (changes all the time but very close to the minimum). Max RPM shows 5940/5499 (left/right). "Control" is auto, meaning the program is not trying to control the speed.
I tried setting the minimum below the values above (eg, I tried changing the minimum to 1,500) but it would not let me. I tried setting the minimums above the values shown, and it allowed me. There is obviously a 'safety' feature in the fan program to prevent slowing down the fans to a value below what is considered safe.
I then installed the same program on my MacBook air. I cannot hear any fan on my MacBook air, but - Macs Fan Control shows a single 'Exhaust' fan running at minimum value of 1200. If I press my ear hard against the bottom of the MacBook air, I can just about hear a faint, faint noise.
So my theory now is - the fans are always running on every MacBook (Air, Pro, etc) - the issue is, how fast they run. And, it would appear (from my MacBook Air experience) that the fans are generally quiet.
I then used the program to speed up the left side fan; the noise grew significantly and was unpleasant. At 4,000 RPM it was a deep, throaty sound. I then slowed it back down, and did the same to the right side fan; at 4,000 RPM it was a gentle 'whoosh' sound. SO ... this tells me the left side fan is messed up (bad bearings, etc). I PRESUME the two fans are the same, and should sound 'similar'. Would others agree with my assessment?

Macbook Pro fans run max speed constantly.

I have one of the pre-aluminum body Macbook Pros, a 2.2 Intel Core 2 Duo with the 15" monitor. For the past few months, both my fans have been running full blast (6000+ rpms) from boot to shutdown. I've tried reseting the SMC, PRAM, and even the misleading "Repair Drive Permissions," but my fans stay full blast. Using Activity Monitor and the Terminal command to check CPU usage, When I have Firefox open everything runs with about a 89%-90% CPU idle. No strange printer problems sucking up my CPU, not watching youtube videos, just high fan speed. I'm hoping it's not a logic board issue. Any suggestions?

Hey, just dealt with the same problem...I think it is finally solved!
Online people offered all sorts of suggestions about the activity monitor, printer queues, etc. Nothing worked. Then I remembered that when I updated to Snow Leopard, it warned me that ONE OF MY APPLICATIONS WAS INCOMPATIBLE.
I searched everywhere (e.g. application support, preferences) and deleted EVERY SINGLE SHRED of that application (Viruscan from McAfee), even the plist files. Finally, no more fan running hot for no good reason!
Hope you can remember which of your apps was incompatible, if not, you may want to delete non-essential applications you have downloaded. Good luck!

MacBook Pro - Fans Run Constantly

Since I installed Leopard to my MacBook Pro anything I do on my computer the fans come on and stay on really loud. The computer gets really hot for every basic task and when I am on battery it drains the battery very quickly. What can I do should I go back to tiger? Is this going to damage my MacBook Pro? I really appreciate any help I can get.
Thanks,
Omar

I think I've found a solution but its more like a work-around.
I've found this on MacFixIt: http://www.macfixit.com/article.php?story=2007110110052021
It basically says: +The temporary fix for this issue is to use Activity Monitor to kill the CrashReport process, the mds process, and others that are spiking in processor usage. See this tutorial for more information on doing so. In some cases, simply killing a process and allowing it to restart will alleviate the issue.+

The fan runs almost constantly but is not hot

My macbook pro is making a fan-funning sound almost constantly, even when the computer is not hot. I have tried shutting down and restarting, to no avail. Any suggestions?
Thanks.

As leroydouglas mentioned, the fans are always running, the idle speed is about 2000 rpm, if your fans are running at high speed when the machine is not working hard you can try a Systwm Management Control reset:

MacBook Pro fans running when plugged into Thunderbolt displays

I just got a sweet setup at work - a new MacBook Pro and 2 Thunderbolt displays. However, immediately upon setup I noticed the fans on the Mac Book operating constantly, even when I was just surfing the net or working in one Microsoft program.
I just spent a few hours working on the laptop - not plugged in to the Thunderbolt displays - and the fans did not go on at all. Within minutes of plugging it in to the displays, the fans started up again. So I think it may have something to do with the Mac Book being plugged into the Thunderbolt displays.
Can anyone help?
Mac Book Pro, Version 10.7.2, 2.4 GHz Intel Core i7, 8 GB 1333 MHz DDR3

Hello,
I'm so sorry for the slow response! I ended up calling Apple because I was still mystified and no one was responding here.
The nice gentleman at Apple told me the following. The MacBook Pro can handle two Thunderbolts max. If the CPU is constantly running hot, then it could be an issue in the long term.
We went through the software update process for the Thunderbolt displays again, and it turns out that the software was NOT updating!!! It's not the usual "click install and the computer takes care of it all" sort of update - unfortunately I don't remember exactly what we did, but you have to go to the Applications folder and actually install something.
You'll know if you haven't followed these steps if, when you go back to check for updates, the Thunderbolt display update keeps popping up.
Since installing that firmware update, I have been using my MacBook with only one display. In the next week, I will probably plug it in to the second display and see if there are fan issues. If so, then Apple told me to call them back and see about further troubleshooting.
I hope this was somewhat helpful. If you are still unclear, I'd say call Apple! They were really helpful! Good luck!
