Fan speeding up and down.. whistling

Hi,
I have a fan that's speeding up and down in the top of my mac pro. It's not the graphics card, but up in the top compartment and sounds like it should probably be replaced.
I know my mac should still be under warranty since it's really been under a year since I bought it, but is this something that's covered?
if not, is it possible for me to even take these out and replace them myself-maybe with something more robust? Where would I find a part number?
thanks,
Dave

Anything is covered and given the cost of a PSU or something.... AppleCare Backups UPS and of course monitor system temps and even fan speeds with something like iStatPro or Hardware Monitor.
I would consider trying to take it in while you can and before there is real harm. PSU failures happen. If was a corroded wire lead, but if it is something else....
I found AppleCare on Amazon to be slightly less.

Help MSI GE60 Fan keeps spinning to 100% and down every 10 seconds.

Hello,
I just bought an MSI GE60 and after 4 days of using, The fan keeps spinning up and down every 10 seconds even when nothing is running on the laptop. Have tried updating the BIOS and the drivers, but no change.
Every time i turn on my laptop this always happen. It goes on when my laptop is on. Even if im not doing anything it still keeps spinning up and down. I checked the temperature and its at 40+ C and my CPU usage is normal. Basically im not doing anything and it keeps doing this fan spin up and down.
Even when the cooler boost is on or off, its still does the same thing, the fan keeps spinning up to 100% and down.
Do you think this is a software issue or hardware? It is very annoying to hear the fan go 100% for 10 seconds then back to normal then back to 100% speed again and when i press cooler boost it doesnt do anything. So even tho the cooler boost button is off, it still keeps doing the 100% fan speed and back to normal again. It keeps repeating.
Can anyone help me solve this problem please? Thank you very much.

I have already tried uninstalling the S-bar and SCM drivers but still getting the fan noise. Also tried the no-battery and no-power reset for more than 24 hours but still having the same problems. The only thing that worked was changing the values in the RWeverything software. The only problem here is that it will work only until I shutdown the laptop. Once I do a cold boot I have to redo the RWeverything changes again.
@reprieve.nagrand
thanks for your case. Can I ask you a few questions more, please?
1. According to your model id your notebook came with just FreeDos, right? Could you please enter the Bios and go to System Information to confirm that you are using Bios 10F and EC version 14.04 (or 4.04)?
2. I urgently need a screenshot of your EC-Page within RWeverything after a cold boot without any modifications. Please try to make the screenshot at that time, when you can barely hear the fan anymore during the spin-on / spin-off cycle.
3. CoolerBoost: with a laptop that has been sitting idle for at least 20mins since last cold boot (no load, please!), can you turn on coolerboost by pushing the button somewhere to the left of the Powerbutton and let coolerboost run for at least 30 seconds. Then turn coolerboost off again and wait for the fan to slow down. Does the fan run continously after applying coolerboost or does it enter its off/on-cycle again. Please try it for at least 5 times and repeat it during other Windows sessions for two times. If this trick works, you are the man to make the video! Please help me out here. Please note, that the coolerboost trick will only work until there is load on the system again. If the fan speed picks up again due to load and slows down again, it will enter the annoying pattern, again.
4. While still reviewing the case and going through my notes, I came across an entry that I reflashed the EC-Controller with the same firmware one or two nights before the problem disappeared. This happened after uninstalling S-Bar and SCM earlier. So, if you are familiar with DOS-Flashing using USB-Sticks you could try to reflash the EC-Controller, than remove all power sources for at least 20 mins. If anyone else is experiencing the problem, please go ahead and report your findings. But please do the reflash only if you are familiar with such things and of course, please do so on your own risk!
Current status and work in progress:
As I haven't gotten hand on a video proofing that simply pushing the coolerboost fan button makes the problem temporarily go away, I am still stuck on there. The coolerboost solution works until the system load increases so much, that the fan level has to be raised. When the system load goes back to idle again, the fan level decreases and enters the off/on-cycle again.
The good news is I managed to customize a programm called fan control tools to somehow automatically apply the changes in RWeverything via a small GUI. This tool will also allow you to set fan profiles for Office, Games, etc. The bad news is, that this will trigger UserAccountControll at least once and it doesn't reapply after a cold boot or returning from hibernate, yet. I am now currently working on a solution that allows the new fan values to be set by Windows automatically using a batch file. This will apply the new values after a normal Windows boot, but not when returning from hibernate, though.
However, if you have found your remedy value for the fan issue within RWeverything, you can turn to Svet in the subforum "Notebook Modified & Private BIOS'ses & EC-FW". He will certainly be able to create you a custom EC-FW with those values written permanently in it.
My case:
The fan problem with my notebook has not (yet) returned. It has been running without S-Bar/SCM just fine. It can even process all fan profile alterations I have made. So, am I just lucky? While I do believe, that the fans of those notebooks experiencing the issue could be "somewhat odd", I find it hard to believe that my fan really suffered a mechanical problem. Without doing anything mechanical wise, my problem went away.
@Warner: I promised to present more videoproof of the case, but unfortunately I haven't managed to get a hold on a suitable video, especially since my unit has been running fine for the last weeks. Please be patient, if I have enough evidence I will post it asap.
One question bothers me though: looking at the EC-page of RWeverything, I was wondering if these are really all values, that the EC handles and checks. Are there any other values, variables that the EC manages and that are not displayed on the EC-page of RWeverything? The reason for asking this, is because I have a video showing the ECpage of RWeverything while the fan does his off/on-cycle and you can clearly see the RPMvalue correspond to the actions of the fan. As you pointed out, the boosts occur because the EC is missing a fan signal, I could clearly see the RPM value at offset 0xCD respond to the actions of the EC. If the controller looks for that value only, it should surely see the RPMs of the fan, as I can see them in RWeverything. So, I was wondering if the EC has other values not shown in RWeverything, that determine if the EC should enter the boost cycle?
While having another look at that video again, to me it appears as if the EC does this really on purpose. It tries to reduce the voltage of the fan to a point so low, that the fan simply starves. Then it boosts the fan up again. The only question is: why does the EC do that? Is there a leftover setting inside the EC - perhaps from another notebook - where such low RPMs were achievable?
You can find the video here in this zip-file: http://www.file-upload.net/download-7371226/MSI.rar.html
In the zip-file you will find three numbered videos, the first one is the most interesting as it shows the annoying fan cycle while the laptop is running idle. In the second one, the user put load on the system using prime95. The third one shows the system while it cools off again after prime95 has been stopped. Sadly, the video is too short as the system doesn't reach its lowest fan state again. The videos were taken in march in Germany, so the ambient temperature is around 20-21 °C or less (normal room temperature in Germany).

jku

Fans Power Up and Down

I just purchased a previously owned iMac G5 for my mother. The fans power up and down continuously. Is there a reason for this and how can I fix it? I also checked the Activity Monitor and didn't see anything.

Sounds familiar, I just spent 2 hours yesterday dealing with my mom's 2007 iMac with the same high-spinning fans, the CPU was going >3500rpm. It had already been to the Apple Genius bar once and they replaced the logic board and fans. However, it didn't go away, so here's what I did:
1. reset the SMC a bunch of times (shut down, unplug all cable, unplug powercord from computer, wait 15+ seconds, plug in power, plug in keyboard, restart.) Fans kept going high.
2. when the SMC reset didn't work, I ran the Apple Hardware Test from startup CD. A sensor error came up: 4SNS/1/40000000:Tp0P and the test told me to shut down, take off peripherals, restart from the Hardware Test and run the extended test. it passed. the only difference was the printer and ethernet weren't connected. So I played around with starting it up with 1, 2 then 3 cables, in different slots. Switching the USB printer cable to a different slot seemed to make the difference in my case. iMac has been running quietly with fans <1200rpm.
good luck, hope this helps.

M55 8810 fan reving up and down

Just picked up a Thinkcentre m55 8810 BQ4 desktop. Works great except for the fan. It will rev up to full speed, slow down, rev up, slow down. Sounds like a teenage driver at a red light with a manual transmission. Doesn't do this all the time but enough to make it annoying to anyone in the room. OS was upgraded to Windows 7, 32 bit from XP. BIOS is Lenovo 2JKT49AUS and SM BIOS is 2.4. Any suggestions? Thanks! Ed

G5 Power Supply Popped - Still works but fan speeds up/slows down nonstop!

Hi,
After applying a security update for Tiger 4.11 on my G5 1.6 a few hours later my machine made a bang/pop sound. It still powers up but once running it sounds like the machine is ramping up to speed and slowing down again. It does this continuously even when machine is running. Apple hardware test reports no problems but i'm concerned. Any ideas?
Thanks.
Dan

I had a similar problem (fans speeding up then slowing down). I have iStat installed so I was able to look at the rpm's of the fan (free widget btw). My CPU fans ranged from 2500 to 3200, oscilated all day long....up, down, up, down ...every few seconds. I noticed my CPU utilization was up, which was odd since my machine was somewhat idel. Looked at Activity monitor and saw my CPU's sometimes reached 90%. The application that was using the CPU's was the printmgr. Stopped the process and everything is ok. I know it is unrelated to the popping sound but you might ck the activity monitor to see what is going on.

MBP Fan Speed/Temp and one extra problem.

My 17" MBP fan is almost constantly running at the max speed (6000 rpm). The temp is at 75 C as well. Since i'm in school the loud fan speed it very annoying and I would like to know if I have a problem with either my temp sensors, logic board or fans.
My other problem is that I get two error messages saying that a usb port is drawing too much power and will be deactivated. I have 3 usb ports my two left ones do not work and only my right one functions.
Any help would be great.
~ Justin

One thing to do is to run the extended version of the Apple Hardware Test and see if anything shows up in the form of an error code. If you get an error code with "SNS" in it, that would indicate that a thermal sensor is either not working or possibly not plugged in. If a sensor is not working, the fans will run all out by default.
Another thing to check is Activity Monitor for an out of control process which is hogging the CPU. Open Activity Monitor and select "All Processes" at the top and "CPU" on the bottom bar. Then peruse the CPU column for any process hat is running amok. If you find one, then highlight it and quit it and see if that takes care of the problem. Sometimes a printer process will hang up and hog the CPU, but it could actually be almost anything.
Regarding the USB ports, you can try to reset them. Power down and remove both the power adaptor and the battery for 15-20 minutes. Then power up again and see if they work. If your USB devices are drawing too much power from your USB ports, you may want to try a powered USB hub.
Good luck!

Fan speed increases and windows 7 freeze on my Satellite A200

I am using Toshiba Satellite A200-24A (PSAE3E) from 3 years now. It came pre-installed with Vista. Last year i switched to Winows 7 Ultimate. Everything was fine.
4 months ago, i switched to Windows 7 Enterprise N. Hated to see no Windows Media Player in it. Now the problem is, during online video streaming (not always the case), my fan speed inceases, so do its sound, and my hard drive gets real busy. 10 seconds later, my window is freezed. Actually, its not responding due to excessive hard drive usage.
I read many articles over the internet, lots of toshiba users are facing the same problem when using Windows 7. But, i couldn't find any solution to it.
This problem started 3 months ago, then for sometimes, it stopped itself. now, it started again 3 weeks ago. If anyone can help me regarding this issue, i will me more than grateful.
Here are my specs:
Windows 7 Enterprise N. Service Pace 1
1.73 Dual core
Ram 3GB
Hard Disk partitions 75 GB + 75 GB

I presume CPU usage goes to 100% and result is freezing. Can you identify background process that can be responsible for this?
> I read many articles over the internet, lots of toshiba users are facing the same problem when using Windows 7. But, i couldn't find any solution to it.
Your opinion is too general. Lot of Toshiba users have a lot of different problems with Windows7. My notebook was also delivered with Vista and since one year I use Win7 32bit and everything works perfectly.
> This problem started 3 months ago...
This make the whole situation more complicated. What have you done 3 months ago? Have you changed some settings, installed some additional software that can be responsible for this?
Unfortunately it is not easy to help in this situation.

Since upgrade to 10.6.7, fans speed up and never slow down

I have an Intel iMac, 2.8 GHz i7, 8GB RAM
Just as the subject line indicates:
After upgrading to 10.6.7, when my iMac starts to heat up, the CPU fan RPM will increase but it will not slow down until I reboot - even if I allow ample time for the machine to cool down and let it sit idle for hours.
Right now, the CPU temperature is only 100 degrees F, utilization is at 1%, and the very loud CPU fan is still running at 4000 RPM.
I've reset the SMC multiple times, and this doesn't help.
The most telling aspect is that in the seven months prior, the fan would slow as the machine cooled off. Not so with 10.6.7
Anyone else experiencing this?
Thanks

Resetting the SMC was my first thought, but you have done that. You might also try resetting the PRAM/NVRAM:

After that if the issue persists, I would call AppleCare.

HELP! Fans speeding up and slow down

What is happening?
The fans on my Power Mac G5 are sppeding up for short periods of time and then they go back to low speed but it's happening almost every minute or so.
Any ideas?
Thank you in advance.
Ah! and I apologize for my english.

Check for dust buildup on the CPU cooling fins and fans. You can use a can of compressed air (the ones for electronics work well) to get some of the dust off. Just be careful to keep the cans upright, or else liquid can come out of them.
Otherwise, try setting the Processor Performance setting to 'Highest' in the Energy Saver preference pane. This will cause the fans to run at a higher speed, but their speed won't fluctuate as much.

BB connection speed up and down, missing dialtone

For the past 3 weeks, I have had ADSL noise on the line and when the phone was picked up the ADSL connection would drop.
An engineer attended and "fixed" the fault.
After a few days following the supposed fix, the ADSL speeds subbenly drop from 11 Mb to 3 Mb, and when you check the phone, it is completely dead. I then switch off the ADSL modem, and after 10 minutes re-start, the ADSL connection comes back on at the higher speed of 11 Mb and the phone is alive again.
An engineer visit yesterday did not discover anything, but about 3 hours after his visit the ADSL connection speed went down and the phone line (voice) went off again.
I have another vengineer visit booked for Friday. Are there any pointers that I should be relaying to the engineer?

not really just simply explain what is happening
Have you tried connecting to the test socket at the rear of the master socket and see if the phone works there

Fan speed issue and warranty question

Hello all,
I've been an staunch Mac supporter for the past 4 or 5 years, but something has happened to one of my last computers, and my current computer, that is making me rethink of which kind of computer to use.
My first problem was an iBook that had its system board go out. It was about 3 years old, the 800MHz G3, OSX 10.3, 14" monitor. I have the hard drive now as a supplemental backup.
Now, less than 5 months after purchasing a newer computer, a 2005 model year, Dual G5 2.0 GHz processor, OSX 10.4.11, the fans are blazing up at max speed, during every kind of thing the computer does, from rebooting, to surfing the net, to listening to music. A diagnosis from a Mac tech says that I need to get my system board replaced for around $750+. I purchased the computer for about $1000. I'm going to college, so I don't have much cash to throw around. I am the first person outside of the campus store to own the computer, and the Mac guy there said that I couldn't get a warranty for the computer. I feel like I have been screwed out of the money I used to purchase this computer.
I've done every kind of power management reset, from unplugging, to rebooting and holding a button combination, to talking with a Mac service rep on the phone, blowing air through the processor heat sinks, reinstalling the deflector and side plate countless times, and sacrificing a dozen goats(the last was a joke for the humor impaired).
Is there nothing Mac can do about this aside from saying, "throw money at the problem and it'll go away."?
Also, since I was the first person, outside of the place that had it for sale, to own this computer, wasn't I entitled to the AppleCare warranty? The cost for repairs on this computer, like I stated before, is going to be nearly 75% of the price I got it for. I just can't throw around that kind of money. What can I do? Is there anything Apple can do by letting me sign up for the warranty? I'd gladly pay the warranty plan costs if it would help me keep the computer and not have to spend even more money by getting a newer one. My parents have had the same windows computer for nearly 2 years without any sort of motherboard problems, yet, within a year span, a laptop AND a desktop Mac would have had to get system board replacements. This doesn't bode well for my confidence in the hardware quality and durability of Apple computers.
Aside from dealing with the noise and throwing money at the problem, what can I do to get this problem fixed!?

I know but it would be the first step before spending serious money, aside from gas which I know is serious also
I'm having problems with my Mac's fans too. I've used every resource I can think of to cure them short of spending cash. The dealer is supposed to be sending me a replacement power supply though.
All I practically got out of my first and recent visit to a Mac Genius was seeing someone without a bone to pick knowledgeably take my computer apart, recognize that I had a problem and give me plain options to try to fix it. I just bought this Mac three months ago. 90 day warranty expires tomorrow. I had a 2.0 that was great, die, just before this getting this one. For me the options are to start spending serious money to fix this or let it be and see what happens. But at least I know for sure now and am no longer flailing.
You might want to consider the free second opinion no matter how redundant his or her advice might be. That's a good machine gotten for a good price if it turns out you don't have a major problem.
The library I should think would have to stand up better in backing the things they sell. If the Mac is shot, yell, picket, protest, till you get satisfaction.

CPU speed up and down in Hardware Monitor...is this normal?

Just downloaded the newest version of Hardware Monitor, and the CPU graph is bouncing constantly between 2000 and 2667 mHz. Is this normal?
None of the temperatures shown seem abnormal...CPU cores are all between 30 and 33 degrees C, the stock 512mb RAM modules are the hottest things at 53-55C.

Basically the Core 2 series processors do tend to save a considerable amount of wattage by simple stepping down a little. I have to say that it's quite remarkable given it's only a 667MHz clock speed drop rather than the usual halving to get the same power savings.

TS1367 My PowerMac G5 will not start up. There is no startup chime, no display and the fans speed up and sound like and airplane after about 30 seconds. Can someone help?

I push the power button, and it turns on, but there is no startup chime, no video display, and after 30 seconds, the fans spin up. Any ideas?

G5 has these hardware issues:
-- bad capacitors on logic board
-- bad capacitors in power supply
-- badly soldered video chip
-- "There were several Mac models with flat panel displays that had bad displays.
     Most had serial numbers beginning with "W8"---the code for one specific factory.
     This affected PowerBooks as well. If that's the case, the rest of the computer
     is probably fine." by Allan Jones in
