2009 17" Macbook Pro fans running at max speed aafter hard drive upgrade.

I recently picked up a 17" 2009 unibody MacBook Pro with Intel Core 2 Duo 2.8ghz, 4gb RAM, SuperDrive and a Samsung 1TB hard drive. The system did not come with the original hard drive and I don't have any other hard drives to test and verify that the new larger hard drive is the cause. I have tried a clean install of Snow Leopard, Lion and even Mountain Lion but no matter what my fans always running at max speed (5k+ RPM). I have looked at iStat and the temps of any of the components in the machine never show more than 42*C so the fans should never be running at full blast. Oddly enough smcFanControl shows 0* temp but fan speds for both left and right are always 5.5k+ and very noisy. Using HDD Fan Control I am able to get at least the right fan to run at a controlable speed but its silence is drowned out by the left fan that still runs on full blast. I have already done multiple SMC resets and PRAM resets with no change in the condition. These noisey fans are driving me insane! I have run every available update as well. Is there a chance that the hard drive or something elses temp not being supported or detectable by OSX is causing the fans to default to the fail safe constant high speed?!

I will have to try that when I get can find the original discs because I have been unable to boot into the diagnostic utility with my Snow Leopard, Lion, or Mountain Lion discs.

Well your just a regular pirate. There is no Mountain Lion disks, it's not even out of Beta and avaialble to the public yet
We thought you were just mistaken but now your tech handy enough to boot a Mac off a Linux live USB, so that means you've been bad and downloaded MT Lion off a P2P network or something.
If your beta testing 10.8 your bound to secrecy and not allowed to be discussing it and posting this sort of question on this forum, but the other one.
If you know anything, OS X must "talk" to the hardware or else the default setting is to race the fans. Linux doesn't do this by default as it's designed for generic PC's which a Mac may appear to be one it's not really. Apple only supports OS X and Windows 7 on Mac's, not Linux.
Obviously something on your machine is SEVERLY messed up in hardware, likely a dead sensor, you bought a used lemon that someone didn't want to pay to get fixed.

Macbook Pro Fans Running At High Speed

My MBP 17" CoreDuo 2.16ghz came back from having the Logic Board replaced at the weekend. All is well except that now the fans run at high speed all the time.
I have installed SMCFanControl, and the current readings are 45 / 113 degrees and the fans are running at 5500 rpm. I took the machine back to the Apple store but when I was there the fans didn't go above 3000rpm (typical huh?). It's nice that the case is now a lot cooler than it used to be but the fans seem very loud to me.
The question is, is this normal? I am not running anything very heavy duty at the moment. Any ideas?
Thanks
Matt

I tend to agree with Ned on SMC fan control (that it arguably causes more problems than it solves).
I had a similar problem with mine recently having the fans run constantly and at full speed. My temperatures never approached yours, but it would fail to go to sleep etc.
I would start with the advice Ned gave you. This is the same path Apple Care led me down in trying to resolve the issue.
Ultimately though I had to do an archival install of the operating system. It is non-destructive so it wasn't a big deal. I just had to slowly re-install patches and observe behavior. Oddly I was able to patch back up to 10.4.9 without the issue re-occuring so the root cause is still a mystery to me.
edit
Patch gone bad maybe? I tried re-applying the 10.4.9 combo before attempting the archival install route with no success. I know that has been suggested many times. Apparenty it solves many issues, but it failed to solve mine.

Macbook Pro Fans Running At Full Speed When Macbook is Very Cooool

Ok, So now i'm pretty sick of the fan noise.
I've done PRAM reset, Power Management Reset to no luck.
So i decided to do some experiments.
As soon as the computer starts, Fans spool up to 6,000 and stay there. CPU Temp 42 Degrees Celsius.
Now My CPU temp does pretty well staying there. In Activity Monitor, No Processes of what so ever. Computer idles at 99% and only 1% being used by system.
So i decided to put the computer in the fridge. As soon as the temps went down 5 Degrees, to like 30 to 35 Degree Celsius, Fans idled at 2000 and as soon as the CPU temp is 40 Degrees, Fans spooled up and kept going all the way back to 6,000.
See as the temp drops on the computer, the fans do slow back down as the CPU temp drops from 40 to 35.
I called apple and the apple tech i talked to said that it seems the fan specs might be set out of whack. Meaning, the temps as which the monitor spools up the fans is set to low. He said it should be around 50 to 60 even 70 Degrees Celsius's before fans should spool up. He said the problem isn't the monitoring system since it does appear to be slowing down and speeding up the fans between 30 to 40 Degrees but it's spooling the fans up and to low of a temp than needed. He told me to take it to a Mac Genius sometime soon.
so before i do that, any apple geniuses what to take a stab on whats wrong and why it's doing this?

My fan runs continually, BUT, with several monitors watching core AND fan exhaust temps I have noticed something strange. The core indicates 28C while the exhaust jumps from 42C DOWN to -128C and then the fan races. While this is keeping the book cool as a cucumber it is driving my wife and now me up the wall. NO I don't have any hung processes. NO the CPU is not caught in a cycle requiring massive computing power. Regardless of the temp the fan runs at the 6200RPM max. Zapping PRAM and resetting the System Management will soon be followed by gravity resetting through my 2nd story apartment window. One way or another this needs to stop!

Fans are running at full speed after hard drive upgrade. Used same brand drive.

My Western Digital 500GB hard drive crashed. The date on it is Aug. 2010. I swapped it out for a Western Digital Caviar Black 1TB. All plugs were identical including the temp sensor cable. My fans now run at full speed. What gives? BTW. This is th 3rd WD hard drive to fail at my office in multiple iMacs. I have a 21.5 iMac i3 3.06ghz. I have tried the SMC reset,.. no luck. Reset the PRAM,.. no luck. Hard drive and computer function perfectly, it just sounds like a loud annoying PC.

After a little more research the only thing I found for 21.5" mid 2010 imac were three part numbers for three sensor cables which are a function of vendor:
922-9215, Hitachi
922-9216, Seagate
922-9622, Western Digital
The strange thing here is these are vendor specific and not model within vendor specific. So you started with a WD drive and replaced it with different model, but still a WD drive. So you would think it would require the same sensor cable.
Maybe the drives are different enough for this to matter. Or maybe you should check the connections one more time. Be it model of drive or connections, whichever it is, the sensor cable is the source of your problem.

Mac Pro fans run at max speed with no load

I recently picked up a Mac Pro 12core and it's been working amazingly well for the past few months... in the past day or two though the fan has been ramping up to maximum and staying there. When this happens there are no processes taking more than 4% CPU and the system is never less than 99% idle. Resetting the SMC controller solved the issue for about 8 hours overnight, but when I started using the computer this morning the fan ramped up about 15mins into using it.
The temps (in degrees C) around the mac pro: (collected with iStat Server):
CPUs: 23,22
Ambient: 23
HD Bays: 23,25,24
Mem Banks: 22,21,25,25,25,27,27,22
Northbridge: 27
Power supplies: 33,36
As you can see, nothing is hot... I'm not exactly sure how to calm it down. Nothing is working any differently than it was, it's just VERY LOUD now where it was whisper quiet, haha

I did order it from the Apple Refurb shop and I think it'd fall into that timeframe (got it early November), but I was kinda hoping for some things I could try on my own before shipping it out?

Macbook Pro fan running at high speed but is not experiencing heavy usage

My computer is 3 years old and I've had no problems.
A few days ago the fan started whirring incessantly after the computer had been on for only 10 minutes or so, even when experiencing minimal usage.
This could be just a coincidence but the issue started about the same time I installed the latest security update, I'm on Yosemite.
Can anyone help?

The first thing to try is a SMC reset.https://support.apple.com/en-us/HT201295 Also check for run away apps. https://support.apple.com/en-us/HT203184 You could also make sure the back vent is not getting clogged.

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:
http://www.amazon.co.uk/s/ref=sr_kk_2?rh=i%3Aaps%2Ck%3Alaptop+cooling+pad&keywor ds=laptop+cooling+pad&ie=UTF8&qid=1344763538
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.

Often I will leave my office and return to find the fan running at max speed and the computer is unresponsive

I also have a MacPro3,1 (2009) I believe and just started experiencing similar issues as described here.
I have scheduled sleep and start cycles and often I will leave my office and return to find the fan running at max speed and the computer is unresponsive or I find the computer booted in to disk utility mode.
I also often loose ethernet connectivity and have to try renewing DHCP lease several times before it will finally work.
Has anyone found solutions for this. I have looked at the console errors right before shutdown and don't really see anything fishy. Here are the last couple of lines before it looks like it shutdown.

Xcode is the latest one, by the way?

You may need many other updates to retain compatibility with Lion. I suggest you reinstall Snow Leopard. Unfortunately, you will need to erase the drive first. Be sure to backup your data if you haven't done so already.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

My MacBook Pro no longer "sees" my LACie external hard drive

Hello,
I need you help with this one. My MacBook Pro no longer "sees" my LACie external hard drive. In the System Profiler (under FireWire) the drive is listed as:
FireWire Bus:
Maximum Speed: Up to 800 Mb/sec
Unknown Device:
Manufacturer: Unknown
Model: Unknown
Maximum Speed: Up to 800 Mb/sec
Connection Speed: Unknown
Can anyone help me to correct this issue? Thank you in advance for your help!!
Nat

I was finally able to resolve this issue. I went to LaCie's site and went to the support area to find troubleshooting steps for my particular drive. It turns out that the problem was corrected when I swapped the power supply cord of the "troubled" drive with another LaCie drive that I have and that seemed to resolve the problem. Thank you Tony for your help. I appreciate you guys!
Thanks,
Nat

I have a macbook pro, and i want to transfer my hard drive from my macbook, but the display drivers and such are different. How do i do this?

I have a macbook pro, and i want to transfer my hard drive from my macbook (500g), but the display drivers and such are different. How do i do this and is it possible?
The Macbook Pro has Mac OS X 10.4.11 (70g hard drive)
The Macbook has Mac OS X 10.6.8 (500g hard drive)

The MacBook's hard drive lacks the necessary hardware drivers to boot the MacBook Pro even though it has a much newer OS on it; that's why simply moving it into the Pro doesn't work. Presumably you have a very old MB Pro, because only the very first MB Pro model (produced January to May 2006) was ever offered with an 80GB hard drive. Are you sure you want to move your big drive into such an old machine? The MacBook must be newer, because the first MacBook was introduced just as the first Pro model was discontinued.

iTunes > preferences > advanced.
point iTunes media folder location to the external
on the same tab, ensure the copy files ... when adding option is checkmarked
okay out of preferences
highlight the content to be moved (i.e. the movies) in iTunes and right-click
select consolidate files from the pop-up menu
wait for the process to finish
when done, you may delete the original files from your boot drive. you may also want to point iTunes media folder location back to your local iTunes folder.

no. airport express does not support the airdisk feature. you'd need an airport extreme (or time capsule) for that.

MacBook Pro Fan running fast after Mavericks update

Hello All! I have a 2009 MacBook Pro 13 inch and I have noticed that after I updated to Mavericks my fan has been running really fast and my computer getting warmer than normal. It's always on a table so there is nothing blocking the port in the rear. Any ideas on how to fix this?

Hey emilyiow,
Thanks for the question. I understand that you are experiencing issues with your MacBook Pro in relation to the fans. Sometimes, this symptom can indicate that the SMC needs to be reset. For more information and instructions on how to do so, check out this resource:
Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
http://support.apple.com/en-us/ht3964
After performing normal troubleshooting, these symptoms may indicate that an SMC reset could be necessary.
Fans
- The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
Additional information:
Using Apple Hardware Test - Apple Support
http://support.apple.com/en-us/HT201257
What to do if you get an error in AHT
Confirm that the power adapter is connected if you're using a Mac notebook.
Confirm that all external devices are disconnected from your computer.
Record any error code given so that you can give the information to a Mac Genius, Apple Authorized Service Provider, or Apple Technical Support Specialist.
Thanks,

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.
