Fan noise with PB12inch?

My PB's fan seems to come on and stay on all the time now.
I've looked at the activity monitor to try and see what's making it do that but I'm not really sure what to look for. I've tried shutting off apps in the background, but the only thing that helps is letting it sleep for a few minutes and then it seems to quiet down.
Any suggestions or similar experiences? It gets louder than I ever remember it getting in the last 2 years - is that a sign of impending doom?

I occasionally have this same problem. I'll sometimes find the screen asleep and the fan still roaring. Here's what worked for me.
Open Activity Monitor (Applications/Utilities) and click on CPU below the window showing the processes running. In my case, the graph on the lower right showed the CPU maxed out by the user (green) with minor activity by the system (red). In the process window above, click on the column heading %CPU until the processes are listed by the percentage of CPU they are demanding. In my case, the faxjobmgr was demanding 85% of the CPU. I have no idea why. I've only used the fax feature half a dozen times on this machine and certainly not within the last few weeks. The machine has been restarted numerous times since I last sent a fax. Anyway, this seemed to be the likely suspect. I double clicked on the faxjobmgr line and a dialog box came up with a bunch of statistics and a "quit" button at the bottom. I clicked quit and the fan immediately began running slower and within a few minutes had stopped altogether. The graph in the lower right showed minimal activity.
Now, in the time it has taken me to write this post, the fan has come back on at about half-speed and the Activity Monitor itself is the single largest demand on CPU. I'm going to run a real-time experiment here and use the above described process to see if quitting the Activity Manager affects the fan speed. Here goes....
Bingo! within 45 seconds of quitting, the fan stopped. Go ahead and try this at home.

IMac g5 fan noise with update to 10.4.11

Has anyone else experienced this?
I have never had any problems with fan noise with my iMac, though I know it's a problem, till the recent update to 10.4.11. After restarting, it sounded like an airplane. Never heard that before. I shut it down and restarted, and it doesn't sound like a plane anymore, but the fan is noticeably noisier than ever before, a constant whine/hum.
Besides the energy saver fix and resetting the SMU and canned gas in the vents, any other suggestions? This is annoying, it's been running pretty perfect for three years till this. Thanks.

The questions are certainly not dumb - almost anywhere is cheaper than Apple for RAM, I recommend [macsales.com] and [smalldog.com] or [newegg.com]. I don't think that going back to 10.4.10 will help, you should really vacuum the vents to get dust out, and make sure that there's nothing hogging your CPU and making the fans noisy, look at Applications>Utilities>Activity Monitor to see if anything is using an unusual amount of memory or CPU.
If you do want to install Leopard, I would suggest making a full backup of your system,I use SuperDuper! to clone my system to a firewire external drive. You should certainly upgrade your RAM if you install Leo, but I don't think your machine will be any quieter with a new OS.
You need to remember that your machine is several years old, and that things get creaky with age (I certainly have). Since you have the iSight, it's not a simple matter to open it and clean the fans off. If you are really disturbed by the noise, you can take it in to an Apple service place and have them clean and oil the fans, which should help enormously.
Sorry I couldn't offer more help, but fans will, and do, get noisy.

Fan noise with Tiger

Hello to everybody!
I have an imac G5 powerpc bought in 2005. It's still running under Tiger.

Fan Noise with Bootcamp 2.0

Hi,
I'm currently running Tiger with Bootcamp 1.2. In MacOS, the fan noise is total silent. However, running Vista with Bootcamp, the fan noise is to the max [pretty irritating]. I'm just wondering if there is an improvement with Leopard and Bootcamp 2.0?
Thanks,
Simon

nvm, figured it out. Fn + Shift + F11. I guess for a shot of an active window it would be the same (without F11) plus F12.

2009 Macbook Pro fan noise with Windows 7

Hello Apple community,
I'm not sure if I should post this in the bootcamp section or not.
I've recently installed Windows 7 on my mid 2009 MBP. I used OS X Lion to create the bootcamp partiton. Everything installed ok but now my MBP's fan is getting noticably loud whenever I use Windows. I've used OS X Lion, and then Mavericks before installing Windows 7 and the only time I heard the fan that loud was when I was playing a video game or doing something hardware intensive. Once I quite the game the fan would stop being so loud. The fan is not consistantly loud, it subsides for a breif period of time only to go full speed again shortly. But it is loud enough most of the time for it to cause me some concern.
Does anyone have any idea about this issue? Is this a consistant problem with MBP using Windows 7? Should I do an update to OS X Lion? Any adive would be greatly appreicated.
Rados

Thanks for replying turostar.
I did as you suggested. I have noticed an improvement in terms of the noise. It isn't as loud for as long a time but every now and then the fan will kick start to make noise again. Is this to be expected?

Loud "rrrrrrhhhh" fan noise with Powermac G5 start up

My G5 has been making more noise at start up. It sounds like one of the fans is making a grinding "rrrrrrhhhh" noise. My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?
Also having issues with the superdrive tray catching on the sliding door:
http://discussions.apple.com/thread.jspa?threadID=1245256&tstart=0

Hi Sopestone-
Have you opened it up and cleaned out the dust? It is quite possible one of or more of the fans has been impeded by said substance.
Try running the Apple Hardware Test and see what results you get.
As far as the tray opening, take a look when you have it open and see if you can see something obvious. It is possible for you to adjust the physical position and relationship to the external door. It is also possible that dust has been sucked through the door and fouled the mechanism.
Luck-

Black screen and loud fan noise-- With Log Info

I am running 10.5.8 on a second gen iMac and am having problems with the fans running super loud, the screen goes black and it cannot be woken up. I have cleaned it out (no dust or dirt) and checked the caps (visually anyway) and they look fine. I am guessing that my power supply is going, but want to check the log (as recommended on the iMac forums) but cannot figure out how to get there. Below is from my log files from the past week.

Shutdown cause 110 is always a thermal problem, which means that your power supply has bitten the dust. It needs replacing, and hopefully, that will be all you need. If you are handy, go to [http://www.jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php] for instructions on replacing it.

No fan noise with new intel iMac?

My daughter's iMac G5 sounds quite loud when the fans kick in,but I haven't heard my intel iMac fans even come on. The loudest noise the thing makes is the hard drive writing occasionally. Is there any way to make sure the fans are working?
iMac 17 Core Duo Mac OS X (10.4.5)

Did as you suggested and still cannot hear any fans. My first G5 unit was the same way till the logic board fried and was replaced. Now it sounds like a jet engine every time it starts to work hard. I hope this one doesn't turn out the same way. My first unit is in the shop right now for it's second logic board and a new power supply.

Correct fan regulation with a T420s in Kubuntu 11.10 Beta2 - Needed only kernel parametres.

My brand new T420s (Manufactured September 7) is a model 4174P4G with a working Win7 fan regulation. There an idle machine has a fan RPM of ~2000 at a CPU temperature of ~40 C in a 23 C room. Those figures are the same whether I choose to use "NVIDIA Optimus" or only the "Integrated Graphics". If I use the "Discrete Graphics" in Win7, idle temperature of the CPU lies between 45-50 C and the fan runs at ~3500-3600 RPM. This is due to the Nvidia GPU, which also lies at ~45-50 C while idle.
Booting a USB stick with the Kubuntu 11.10 Beta2 Live DVD while doing nothing with kernel parametres, produces a cool fan exhaust with "Integrated Graphics" and a slightly hot one with "NVIDIA Optimus". I did not test much with "Discrete Graphics" since the open source driver failed to work, and the closed source Nvidia driver wouldn't download - from the ubuntu server.
Doing nothing with this modern kernel (K/Ubuntu use a 3.0-something-homebrew) the idle machine had a fan doing 4000 RPM - constantly - while the CPU sat at ~40 C. That is to say, the fan is not regulated (This was observed by the command "sensors" from the lm-sensors package. Modprobe the kernel module "coretemp" if you want to see more info from "sensors"). I can only presume it is an unintended consequence of two choices the kernel developers have made.
To 'revert' those kernel choices we must boot with the kernel parametres --> pcie_aspm=force i915.i915_enable_rc6=1 <-- OBS: Both the parametres must be present to get a working fan regulation.
The parametres deal with PCI Express Active State Power Management and Intels GPU driver. Why the fan is effected by such a double combo? Someone should ask the (probably ACPI) kernel developers about that. As a nice side-effect we also get a much improved battery run-time. That is actually where I stumbled upon the parametres, in discussions about power regressions with newer kernels.
Anyway, using this, a boot with "Integrated Graphics" gives even better thermals than Win7. I was idling at ~37 C and a 1850-2000 RPM fan. With "NVIDIA Optimus" there were short periods of 2000 RPM and long bouts of 3500 at ~45 C in the CPU.
/MTJ

UPDATE: I was a bit hasty with my comments about the USB ports. I've now actually _installed_ Kubuntu 11.10-final, and plugging in a simple USB mouse does not break fan regulation. Neither does the USB harddrive. BUT, the HD connection raises the temperature somewhere (hidden motherboard sensor?) and that is enough to kick the fan into its 4000 RPM state. Unplugging the HD and idle waiting, waiting... will eventually bring back the sane fan RPMs.
Btw, waiting seems to be the (ab?)normal name of the game in Linux. Win7P has a much quicker fan regulation. Here the fan ramps up its speed even with minimal workloads - like typing this message in Firefox, and it takes a looong time to fall back.
@ homeyclaus, Hi.
> I get nothing of the sort with a vanilla T420, all-intel graphics ...
Machine better at thermals probably (slightly thicker, no nvidia card to generate heat etc), and the BIOS is different from the "s" and "si" models. But constant 4000 RPM and fan noise with these models has been an ongoing saga even in Windows. See the massive "T420s Fan noise Issue" thread - takes a full day to read through it, and "T420 fan noise ?" at:
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T420s-Fan-noise-Issue/td-p/443569
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T420-Fan-noise/td-p/417971
Could be a number of things, but ultimately it is a job for the Lenovo BIOS hackers. The EC (embedded controller) is responsible for regulating the fan, and the ThinkPads have a long history of being shipped with bad EC code. See the (not updated for newer models) thinkwiki page:
http://www.thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_issues
> I did notice that my previous laptop with an NVidia GS8400 discrete chip did run the fan pretty high though.
You and me both ;-) On my previous machine (Acer) from 2005 I had to undervolt both the AMD-64 CPU and the NVidia GPU, install extra passive cooling - copper fins, plates and thread - and build an electro-'mechanic' manual fan regulator to get the noise down to a bearable level. But I had fun doing it as well...
> Are you running the NVidia closed-source X server?
Nope. Haven't gotten to experimenting with that part yet.
> How is the system handling the switch-over from discrete to integrated graphics?
Handling? Win7P greeted me with something like a 1024x768 screen before I could configure the Intel card. Once done, I saw no difference (except less system heat) from running in Optimus mode - I'm not a gamer or 3D artist. Linux desktop works fine with its OpenGL effects when I set "Use VSync" to get rid of window tearing. I might never need to switch on NVidia again!

Santa Rosa Macbook fan noise fix, sort of

I don't know how many of you guys noticed this, but when I got the new Santa Rosa MB it was definitely louder than my previous C2D Macbook. Even when idle doing nothing.
I found out that the lowest rpm on the new Santa Rosa goes at 1800, which in a quiet room at night is way to loud personally.
In order to fix it just download fan control 1.2 and then put the lowest RPM setting to 1000. For me that instantly made the MB super quiet again.
Hope that helps to those that wish more silence out of the Santa Rosa books.

I made an appointment at the Apple Store I got it from (4 days after I purchased). I told them about the weird clicking noise and they took it to the back (store was pretty loud) and came back in a few minutes and offered to exchange it since I was within my 14 days. The new one is way quieter and only makes fan noise with intensive processes (as expected). Doing some research after the fact, I believe my issue was the ticking/clicking one described here: http://www.appledefects.com/wiki/index.php?title=MacBook#.22Mooing.22fan_noise.2C_Ticking.2FClicking_Fannoise Overall, they handled it pretty well (I was prepared to field an inquisition about this manufacturing flaw, luckily I didn't have to and they recognized the problem pretty quickly), and I'm finally enjoying my new MacBook.

Fan noise when screensaver starts

Hi
I've been reading about this issue but don't find any post that relates fan noise with screensaver.
I had fan noise problems similar to some posted... things got better,but now it only becomes unbearable when the screensaver starts.
Any ideas ?

I'm experiencing the same issue since I've replaced the standard Nvidea for an Ati Radeon HD3870 video-card. When the screensaver starts the noise of the fans increases. Don't understand it since it's just the solid colors effect.. :-s

G5 Users: Are you experiencing Fan Noise?

Simple Question,
Often read complaints about fan noise with G5's, since normally people only write when they have a problem, am curious if this is a given problem with the current desktops.
Please let me know if you experience this problem
ever? frequently? Please specify if your running the fall 2005 models.
Many thanks,
xandra

Mac Medic, do you have a dual processor (quad) or a
single processor? On our quad, the intake fans
bottom out at 1000 rpm and exhaust fans at 1250 rpm.
I haven't seen them any lower than that. I think
Apple set some minimum fan speed values and the 2.0
and 2.3 ghz models can get down to 600 rpm. The
fans really don't start ramping up until the
processors hit 125-130 degrees.
I have a 2.0GHz. I believe Apple has the fans set to run a little higher on the quads. The quad's CPU cores are running cooler than mine at idle. The coolest mine ever get is around 113F. Highest is around 137F, but fans stay around 600RPM all the time.

Latest reports on MBP 13' 2011 fan noise?

Hello there,
I'm very close to get a new MBP core i5.
however I've been a little discouraged by the numerous reports of overheating and consequent loud fan noise.
I've developed a sort of a phobia to fan noise with my current Macbook and I'd hate to find myself in similar waters.
I'll be using it with Logic, FW devices, external monitor on day long sessions.
Anyone with similar set up care to share their experience with fan noise on this specific model?
all the best

Problems with new Yoga 2 Pro (battery, fan noise, yellow, screen orientation, on-screen keyboard)

I purchased the Yoga Pro 2 on Thursday October 17. I love the computer for so many reasons, (especially since it replaces my 4 year old Compaq that was 6.5lbs!) however, I am also having a few issues with it.
It is the i7/8GB/256GB model from BestBuy. I am experiencing the same yellow issue as is mentioned by many on here. I didn't realize it, though, until reading these forums and then comparing to my old computer and my ipad and iPhone. A little disappointed, though it looks like Lenovo may be working on a solution.
But the real reason I originally came to look at this forum is because of 2 things: my fan and battery.
The fan (on the right side of the keyboard) is always on! I didn't expect this, and am wondering if mine is a lemon or if others are noticing the same thing. It's pretty noticeable, especially in a quiet room. I was showing off my new computer to a friend and the very first thing she said was that it was loud! She was using a MacBook pro, which wasn't making any noise at all.
The second thing is the battery... I am attaching 4 photos all taken within a few minutes of each other. If you cant see them, they are all of the battery meter on my screen. I am listing the time of day (to show how much time passed), percent remaining, and time remaining:
10:04 (88%) 306 hr 15 min
10:05 (88%) 8 hr 48 min
10:09 (86%) 4 hr 54 min
10:29 (81%) 5 hr 12 min
I feel like my computer just cant make up its mind!!
Another issue I had... I turned on my computer to show it to a friend (same friend who said it was noisy) and the screen image wouldn't flip when in any of the modes. This means I showed her the stand mode with an upside down image. Even in tablet mode I couldn't get it to flip. I turned the computer off and then on again, and luckily it decided to work, but it was frustrating, and I hope it's not something that becomes an issue.
Also, when I have the computer in tablet mode, the keyboard automatically pops up when I click somewhere to type... but this doesn't happen in stand mode or tent mode. Is this normal? I would have thought that the keyboard would appear in any of those modes, since the real keyboard is not accessible in any of them. And of course now that I am testing it out while writing this, none of the modes (including tablet) is having the keyboard come on screen. Of course, I know I can always choose the icon on the task bar to bring up the keyboard, but it would be nice if the computer did it automatically since it knows there is no other keyboard accessible in those modes. Is this an issue anybody else has had?
I really do enjoy using this computer, but some of these issues really need to get worked out if I am going to keep it. I'd love to hear if anyone is experiencing anything similar, and if there are any good fixes!

I just got a Lemontine Yoga 2 Pro i5/8GB/256GB from lenovo.com and the silver one from BestBuy in the same configuraiton. The silver one has no issues except for the crazy number of hours remaining on the battery which is fine, doesn't bother me. The fan noise is very quiet, and you can only hear it if you put your ear up to the vents in a quiet room.
Now the Clementine one...It was heating up pretty good. I put my ear to it on many occasions and can hear nothing at all, the fan is either missing LOL or doesn't work. I had an issue where I left the thing on for 4 hours, but sleep is configured after 5 hours. When I tried to use it, it showed me the screen brielfy, then blank. Tried hard reset, called Support, nothing. Support says its dead. Ok, an hour later, it turned on. I'm guessing it was too hot and was in some mode to protect itself, like a smartphone that is left out in the sun for some time, it won't power on till its cooled down.
I'm still in process of trying to get a hold of Lenovo to swap it, but since they no longer sell this configuration, I doubt they'll be able to get me a new one.
The silver one from BestBuy us solid though, love it, best in class in my opinion...actually got it from Future Shop sorry...from Canada, but they're essentially the same store.
