PPC QUAD Owners -- Got Bad Fan Noise w/Logic (or just in general)?

I'm having a terrific noise problem with my Quad's (now) overactive fans. When I first got the Quad this was not a problem. Seems to have started after an update from 10.4.3 to 10.4.4 or 10.4.5. With respect to Logic, the fans go into hyperdrive (blowing relatively cool air) after I launch Logic, even when it's sitting idle with a bare-bones autoload song loaded (no plugs at all). When I quit Logic, the fans start to calm down but it takes sveral minutes to settle down completely.
Even accessing the dock or loading up this forum on Safari will cause the fans to rev, but Logic is the thing that seems to trigger this behavior the most -- and the worst.
Anyone else with a Quad is experiencing the same thing? Particularly with Logic running?
I'd be grateful if anyone can offer offer troubleshooting advice. Here's some info:
- reinstalled the system software numerous times, no change
- all Apple RAM installed (6 G)
- running 2 monitors, but with only one connected, no difference
- using wall current or UPS current makes no difference

Thanks for the continued feedback/replies. Will be living with the computer/hair dryer combo for another week as the Apple store techs in my area are all booked up until after Labor Day. Gotta say, tho, that the $100 to be a ProCare member gets ya good attention from those guys.
Would still appreciate hearing about other Quad owner's experiences with their fans/noise level of their systems, just for comparison sake.
Tele, glad to hear your fans are well-behaved. Wanna trade? ;-)
Thanks again everyone.

Fan noise after memory Upgrade

Hello,
I have a Mac Mini and I upgraded it to 2GB of memory and now I got a fan noise constanlty going. I have tried to reset the SMC and I left the machine without any cables plugged in for about 45 minutes after my second attempt.
I had upgraded the machine before and this never happened.
Any clue as what I got to do or what may be wrong?
Thank you for any help!
Mac Mini 1.66 GHz Mac OS X (10.4.8)
Mac Mini 1.66 GHz Mac OS X (10.4.8)

To quote from a post by "damfair":
There is a fan speed regulation wire at the front of the Mini that needs to be unattached to get to the RAM slots - if this is left unattached, the fan continually runs at full speed. Could this be the source of the constant fan noise?

Quad Idle Fan noise?

I own several powerbooks and recently bought my first PowerMac.
The Powerbooks are silent.
The Quad makes fan noise. It's not very loud, but the fans are clearly running. I can feel cool air from the front vents. Normal?
I have installed a second internal drive (Hitachi) and 4 gigs of Crucial RAM.
The machine was silent until I loaded on Photoshop, FCP and several other programs. But I really haven't used any of the programs yet.
Since I have not done any serious work on the machine yet- so I am not sure if this normal idle noise or something else.
Should an idle Quad be fully silent?
Thanks

My Quad is much noiser than I expected. My PowerBook can barely be heard. My iMac (since replaced by the Power Mac) was Rev. A and suffered from the known noise problems but was quieter than the Power Mac. Are these fan speeds typical? (Obtained from Marcel Bresink's Hardware Monitor utility.)

Our brand new quad core imac will not start up. We hear a drive and fan noise but the screen remains black. Any suggestions?

The computer shut down on its own while we were gone and will not start up again. When we press the power button we hear drive and fan noises but no chime and the screen remains black. Any suggestions?

A pretty common thing for computers that have been shipped is a RAM chip becoming dislodged just enough to cause what you are describing. Try re-seating your RAM chips. Basically just pull them out and push them back in. Take a look at this article if you need some direction on this: http://support.apple.com/kb/HT1423

Mac Pro 2x2,8 Ghz - Fan Noise - Please help evaluate

Hi Guys,
Since yesterday, I'm the proud owner of a Mac Pro 2x2,8 - Really happy - really nice machine.
However I'm slightly irritated by the posts I've read all over the internet, saying that you can't hear the fans of this machine at all in idle.
As you may have guessed, my box is not silent at all - it is quite quiet compared to other noisy PCs, yes, but no match for the previous iMac 24" which it replaced. You could hardly hear the iMac versus now the Mac Pro... you notice it's there... sitting under the desk - audible.
I realize that fan noise is highly subjective, and I'm using the Mac in a completely silent environment. No AC, no nothing. I've tried the following: removing the hard drive and silencing the graphics card... Upon bootup the Mac would quickly "turbo" it's fans and then go to it's normal state. The loudest fan (which is drowning out all other noise) is the one at the bottom front (CPU?).
Looking at istat, it's in normal parameters (500rpm or so) and doesn't move up or down...
Comparing it to other devices, it would sound like a PS3 when having played 1 hour (fan speed at level 2-3) or an (quiet) xbox in idle mode (dvd not spinning). I know... geeky comparisons
Now, again - not close to my interpretations of "whisper quiet" "can't hear it at all"... "only hear it when I put my ear to the grill" "sounds like it's cooled passively"
Which makes me think that either
a) people out there are deaf /
or
b) my Mac needs a closer look by a genius
Would really appreciate your opinions.
Thanks,
Tom

hey tom,
you might have the same problem i have. I have the 2.8 octo 2008 mac pro. and it used to be whisper quiet. I was amazed. But recently as in the last few weeks the graphics card fan has become audible. I put in an e sata adapter last week and while inside the mac pro I took a look at the fan to see if it was dusty or visibly distressed. Nope. Couldn't find anything wrong with it. So now i'm just dealing with the noise. Which is too bad cause I really really really don't like fan noise. But the air conditioners on most of the time now so I really can't complain about a little fan noise compared to the ac's grumbling.
but i'd like to know if others are having this problem
thanks,

Why do I have fan noise after OS 10.7.5 update?

I used to have moaning sounds coming from my Mac Pro (Quad Core, early 2008) when I was in motion graphics programs, or in NetFlix. But ever since I updated to OS 10.7.5 3 days ago, the fan moaning is incessant. Help! I just spent $200 on an old geezer "official Mac" technician, who came to my home office and spent 2 hours doing DiskWarrior!
I am so busy right now, I can't stop to take the tower to a local authorized shop. Will the noise sink my CPU? What is causing it? Is it a glitch in OS 10.7.5? Or do I need new fan(s)?
Anyone hear complaints of sudden incessant noise other than mine?

I used the following:
Copy and past the following in terminal followed by your password when asked for:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
Note that if you've got anything listed in the Spotlight control panel in Privacy, it will be deleted.
To turn it back on (which I haven't tried yet since I don't use Spotlight):
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
When Spotlight is frantically reading everything and indexing it, a lot of CPU % is used, and the HD is being exercised too. That generates heat and could be the cause of the increased fan noise when your Mac Pro speeds up its fans to try to protect itself. 10.7.5 seems problematic in this respect and since your noise problem started after the 10.7.5 update, the two might be connected. Apple tends to run a Mac Pro's fans very slowly to keep the machine quiet, so any speedup would be noticeable.

My Powerbook G4 make some fan noise. Please help!

From last night my PowerBook G4 makes fan noise. It sounds like fanning sound when the computer is overheated during hot summer. But my room temperature is aroung 70 degree.
It happens when I open many windows but I need to open them to trade some at TDamertrade.com site. To check other sites too.
I would very appreciate any suggestions I can try to fix this fan sound.

It is possible that you are having these issues because you installed the MacBook Pro SMC Firmware Update 1.3 by mistake:
*http://support.apple.com/downloads/MacBookPro_SMC_Firmware_Update_13*
I remember when this was released that PowerBook G4 owners were seeing this update via their Software Update application. Sometimes I just install those updates without closely reading what they are for exactly. Anyway, I know it says for high work loads, but you would be surprised how easily the fans will turn on high just from simply web browsing.
I suggest that you first try resetting the PMU:
*If the computer is on, turn it off.*
*Disconnect the AC Adapter and remove the computer's battery.*
*Press and hold down the power button for 5 seconds and then release the button.*
*Reconnect the battery and AC Adapter.*
*Press the Power button to restart the computer.*
If the above works for you (great), if not, try resetting PRAM and NVRAM:
*Shut down the computer.*
*Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.*
*Turn on the computer.*
*Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.*
*Hold the keys down until the computer restarts and you hear the startup sound for the second time.*
*Release the keys.*
If the above works for you (great), if not, try archive and installing:
*http://support.apple.com/kb/HT1710*
If the none of the above worked for you (not so great), do the following:
Go to your closest  Store next week after making an appointment with a Mac Genius:
*http://www.apple.com/retail/geniusbar/*
I hope that I helped you solve your problem, but do post back if not and I will help you narrow down what is going on even further. Personally, I feel that I am better than going to see a genius because most of them are just trained for Intel machines these days out in CA, where as, I know all the way back to PPC and Mac OS 7. Best of luck.

Removing Fan noise from lighting

First, thank you for your responses... Secondly, I know these problems should be thought of in advance and not to rely on post so I would appreciate help rather than criticism...
There is noise from the fans of the lights. A single person is speaking to camera in an inside room. I have reduced noise (set noise print –> reduce noise) in ST Pro, which got rid of fan noise (-45db), but distorts the voice so it sounds like he is speaking underwater. I added an EQ filter, but can't get this to sound very good...
I have Soundbooth CS5 and FCS. Thanks for any help.

STP noise reduction has a tendency to do that rather quickly. The only thing that helps is to reduce the amount of noise reduction which defeats much of the purpose.
First first adding some parametric eq to reduce the bad frequencies and then do a noise print and noise reduction, using less reduction, no lower than about 54dB.
You can also go into the spectrum analyzer and try to carve out the bad frequencies. This is more difficult than in Soundbooth's version, which is were I generally head off to for that sort of work.
Recently I've been trying Isotrope's RX noise reduction and find it miles ahead. Where I was using it I found I had to back up and reduce background in a lot more shots I'd previously just skipped over. It's one of those things that can be too good. It's spectrum analyzer is also quite good.
Good luck

Intermittent fan noise

I've got a G5 quad, been running fine. Over the past 3 days the fan has intermittently come on. It "revs" up very briefly sometimes, other times it comes on strong for several seconds. Any ideas about what's happening. Environmental temperature hasn't change for several weeks.
Thanks

I have 2 Power Mac G5 and both have increased the fan speed since I last turned the "on" with the side covers opened. I tried resetting the SMU and PMU button on the logic board a few times, as instructed by Apple support with no success.
Annoying noise but I learned to live with it. Computers work fine, sleep mode and all. The only problem is the loud fan noise. Is there a software or something that can be done? I even thought about disconnecting the fans leaving without, but I suppose they will burn.

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.

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.

Macbook pro- OSX lion 10.7.2 fan noise

I just bought a macbook pro laptop, upgraded it to the Lion version, it is now 10.7.2, with processor of 2.7 GHz intel core i7, memory of 8GB, 1333 MHz DDR3. Whenever I am on a program like imovie, safari, iphoto, charging my smartpen...etc.... the fans goes off like crazy. It lasts for a very long time. Sometimes the noise get so bad, it goes from loud to louder...... I don't know what the problem is.
I am a new mac user, I have no idea how to install, delete, clean softwares. Please help?? Thank You ...

Thanks a lot for replying, but what exactly does the istat widget program do?
Also, the fan noise seems like a normal noise every time I launch a program, but it's getting to the point where I am frustrated(annoyed) of the fan noise. I would've thought that upgrading to a Mac book would cause less fan noise because of it's high processor. Sometimes I feel like I should go back to a Dell or HP because of this problem, but at the same time, I love my laptop. ;)

TA25225 Display Flickers in my 21" Imac Intel. This happened after the fan noise in my machine. I also reported the problem and gave to the service centre, but the problem still persist. Please help. I purchased it 3 - 4 weeks ago

Hello,
I purchased my imac intel 21" 3-4 weeks ago and in the 2nd week i faced an issue with the machine. When i switched on in, there was a fan noise and a white screen. The machine had hanged. I reported the problem and gave to the service centre. After testing for a week, they said that there is no problem with the imac. Again i faced the same problem after receiving it from the service centre. They again tested the machine for 3-4 days and reported as no problem with the machine. Couple of days back, I received the machine from the service centre, and on the same day when i switched it on, there are flickers in the display. Please help me solve the issue. I am from India. The service here is very bad.
Hope for a resolution
Thanks

Hello RedDevil07
Yes I agree with seventy one. It's common sense to do this, especially now. I would also contact AppleCare and report this issue with them, it will get documented and you will have a caseID that you can refer to when talking to them in the future should this issue go one.
Be polite with AppleCare and your AASP. Hopefully everyone is being honest and trying to help you and not what might appear to be the opposite.
Patience is a virtue, but I thoroughly understand your frustration.
Let us know how it goes, we are here to help in whatever way we can.
I encourage you to contact AppleCare to report this experience and get their recommendations. There is an expectation that you should have that AppleCare is there to help you as a customer. I am sure they will too!

Mac Pro will not boot, constant loud fan noise and nothing else

hello,
earlier tonight,i put my mac pro on sleep, then later on, when i wanted to take it off sleep and use it, it made the loud fan noise, which it always does but goes away, but this time it the fan wount slow down and the loud noise stays and i dont see anything on the screen. im guessing the fan noise is the ATI x1900 card...
any help please..i just bought it 2 months ago...

Hi, here are the steps I would go through. I would unplug the Mac Pro completely from everything and look at the video card's fan intake to make sure it isn't plugged and just make sure everything "looks" correct. I would then plug the machine back into one monitor/keyboard/mouse (leave all the other peripherals disconnected. Once that is done push the power button. Does anything happen? If not then if you have another mac and an external hard drive, make a copy of the OS on the drive and see if you can get the Mac Pro to boot off that drive. If the video card doesn't work then it will not show anything when booting off an external drive. If the external boot does work then I would suspect that you have a bad hard drive (or it crashed). At that point I hope you have a back up of all your data and such.
Mind you these are steps I would go through. What a nightmare. One other thing to check, make sure your monitor didn't die.
