Macbook Pro Fan issues

I have a Macbook Pro 2.33. It recently starting making some noise. I suspected it was the fan. I went on youtube to see how to replace a fan. I found several videos on how to do that. I opened the laptop, powered it up and found that the fan on the right side (which is the one that makes the noise) does not run at start up, only the fan on the left. Eventually, it runs and starts making noise. First, is this normal? Or do both fans run when the machine is turned on? If both fans are supposed to run when the machine is turned on, then I know that I have to replace the fan. I know how to do that as I have already removed the defective fan, cleaned it up a bit and re-installed it. The fan does spin, but it is still not working correctly. Also, where is the best place to get the replacement part.
I thank you in advance for your input.

Both of my fans run all the time and I have no issues, so I surmise that both should be running all the time.
Try iFixit, or EBAY or if you want to pay top dollar, Apple.
Ciao.

Macbook pro fan issue

Hello there, I have a 2009 Macbook Pro, which apart from this issue is still running as strong as ever.
I've had this issue for awhile, but for whatever reason have only sought to finally fix it now...
Whenever I finish using the Macbook, I usually just gently close it, I don't turn it off or swich it to sleep or whatever.
The issue is that when I open it again, if at least a few minutes have passed, 9/10 of the time it ROARS to life for 1 or 2 seconds and the fans run full blast and then shut right off again. Its not a huge problem but that volume and speed they run at for that couple seconds is alarming.
Obviously it hasn't always done this, but it's had this happening for off an on a year probably.
Is this normal with an older macbook? Should I start hitting sleep before closing it? Or possible a issue with the CPU or fans?
Also, I used to use SMC fan control for gaming sometimes but I haven't had it installed for ages, if that helps.
Any help is appreciated, thanks!

"Is this normal with an older macbook? "
No.
"Should I start hitting sleep before closing it? "
Shouldn't be necessary
"Or possible a issue with the CPU or fans?"
See below, first.
"Also, I used to use SMC fan control for gaming sometimes but I haven't had it installed for ages, if that helps."

Retina MacBook Pro fan issue

I've noticed when playing games or doing anything graphic intensive, only 1 fan goes on? as far as I know the RMBP 13 inch has a left and right fan but I only ever hear the right fan. I downloaded "macs fan control" and only my right fan shows up there. Is this an issue that needs resolved?

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.

What is causing my Macbook Pro fan to run constantly?

Hello. Recently my Macbook Pro fan has begun to run constantly at high power. I've checked the activity monitor and even when there is little RAM or CPU this occurs. I am wondering if the issue is the hard drive because the I am seeing spikes in disk activity at random times even when I am not using the hard drive. The computer is actually heating up when the fans are on at full power, so this also leads me to believe it could be the hard drive. I have already tried resetting the system management controller. Any other ideas? What should I do about this?
Thanks a lot.

Try raising the the the machine with wood, or , plastic botttle caps t get it up an inch or so, that way there is more air flow under the MBP to help with the air flow to help keep the cooling more een. Hope this helps.

My Macbook Pro fan is always running and slows don't my computer, What's the issue and is there various ways to try and solve the issue?

Hey Unknownflavour,
There an be a few different reasons why your fans are running. I'd read up on the function of your MacBook Pro's fans in the following document:

Macbook Pro Fan Trouble.

I recently sent my Macbook Pro Fans to get replaced. The problem was that my fans started to work even when the computer didn't need it. They would accelerate up to 6000 RPM and I would only be running Safari and iChat. Then the computer's fans would start to slow down and then speed back up. I sent in the computer for repair to get the fans looked at and they replaced them. Well the problem is still persisting. Should I call them about it again or is this normal? I only ask because I don't know if it is or not.

I have the same trouble with mine. I took it in for repair as it had a logic board issue, and they gave it back to me yesterday, but when I started using it, the fans ramped up to 6000rpm constantly for the entire day.
This morning I installed Fan Control to see if that would help, but it appears that Fan Control is not actually doing anything. The fans have been stuck around 4400 rpm at 35 degrees celsius even though I told Fan Control not to run at anything above 2000rpm until it gets to 40 degrees.
Is there a mysterious apple setting that says don't go above 35 degrees, or if you do ramp up the fan speed to max until it gets below it again, because according to Fan Control that is what is happening. It is not logical to be wanting to keep a powerful modern laptop at that temperature when the fan noise is so high. 45 degrees would be a fine operating temperature.
BTW, I checked the Hardware test and there is nothing to report from it.

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:

Can't install windondows 8.1 on my macbook pro - format issue

Can't install windondows 8.1 on my macbook pro - format issue
Running latest version of Mavericks.
Followed the exact bootcamp proceduce.
Have official window 8.1 version on cd.
All goes well until I have to format the 65Gb partition. Disk=0 and partition=4
Can't get over it. Altough I formatted it via a hint found on the internet with "dislpart" in NTFS. Wich also went weel and give the labelname "BOOTCAMP". But still no luck.
I have two questions:
1/ How to start my mac again in normal mavericks mode?
2/ How can I overcome the windows installation issue?
Tried already a lot of hints found on the internet.

First, make a time machine backup. You will need to erase ands reformat your hard drive. I had the same issue. The issue is that you can't install Windows using bootcamp without having the hard drive formatted as Mac OS Extended (Journaled). Do this from disk utility or recovery mode (hold down command and r at startup). Then you have to restore the backup to the hard drive. Then make a usb installer drive with bootcamp and then partition and install. Here's a tip: after you install bootcamp and are in the Windows desktop, go into the installer drive and then go into the bootcamp or support folder, then find a installer that contains the Apple bootcamp drivers. Also, you will need to convert the disk to an iso file. TO MAKE THE USB DRIVE FROM A DISC, USE THIS LINK

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.

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.

Macbook pro shutdown issue

Macbook pro shutdown issue when I push the power button it immediately goes into sleep mode

Hello Marrio22,
Thank you for the question. With OS X Mavericks, the power button has new functionality:
OS X Mavericks updates the power button behavior on Mac computers.
Using the Power Button to Sleep & Wake
Tap the power button in Mavericks to put your Mac to sleep or to wake it up:
Tap the power button once to put your Mac to sleep.
Tap the power button again to wake your Mac.
Press the power button for less than a half a second to sleep or wake your Mac. This duration is similar to pressing the Space bar or Return key to wake your Mac. The power button works this way across all Macs using OS X Mavericks, including both notebook and desktop computers.
Accessing the Shut Down Dialog
Press and hold the power button for 1.5 seconds, to bring up additional options:
Forcing the Mac to Turn Off
Hold down the power button for 5 seconds to force the computer to turn off. Important: You may lose unsaved documents if you force the computer to turn off this way. Use this method of turning off your Mac only if it has become unresponsive for an extended period of time. Normally you should shut down the computer by selecting Shut Down from the Apple menu, or from the shut down dialog pictured above.

Do you think my macbook pro fan could be broken?

Earlier today when I opened my laptop the screen was black and it appeared to be shut down. I hit the restart button and when the screen came up it said that I had "shut off my laptop due to a problem", though I did not manually shut it down. It was working 100% fine yesterday, so I'm not sure what could have happened to it. I know it wasn't my battery, because I had a full charge prior to shutting it and upon restart I still had a reasonable charge. I was more or less ignoring my laptop's unusual pop-up until I noticed that my computer was feeling much hotter than normal, so I checked iStat pro to look at temperatures. The CPU temp was around 82 degrees or so when I checked, while I was playing a videogame, which doesn't seem too high but the area around my keyboard felt much hotter to the touch than normal. What is really concerning me is that iStat says my fan is running at 0 rpm, even while I was playing a graphic-intensive game. The CPU is down to 65 degrees since I have stopped playing the game, however I have heard that your laptop will shut itself off to prevent overheating, and I'm wondering if this is what happened to my laptop sometime between yesterday and today. Does it sound like my fan could be broken? There isn't an apple store very close to me and my warranty just ended so I'd rather work it out myself if possible. I don't believe it is a faulty sensor either as iStat gave me temperature readings for everything. If you think my fan is broken, do you have any advice or know how much it would cost to fix/replace?

Good detective work.
I don't believe that 80ºC is extreme for occasional use, but over extended periods of time, this can stress your machine. I beleve you should visit your local Apple Store. They can determine if the fan is broken.
In the meantime, I could avoid:
- CPU-intensive activities like 3D gaming for extended periods of time.
- Using your notebook on your lap. That can raise its temperature thirty or more degrees.
- Dust or dirt can choke the fans, increasing temperatures and even the risk of fire.
Replacement of a fan is not very expensive, if it comes to that. You can also do it yourself:

Macbook Pro Fan Speed

Hi. I was having some trouble with my temperature of my MBP, but I somewhat solved it using Temperature Monitor and smcFanControl. I turned the fanspeed to Higher RPM in the smcfancontrol menu, and my temperatures are down from ~95 celcius to ~65 celcius (when playing Minecraft / other extensive tasks.)
Now, I would like to bring them down more (should I?) because I feel 65 c - 70 c is still really high...
So, my only question is: In smcFanControl, the Higher RPM setting is 4000 RPM, should I change that to 5000 RPM? I know it would help, but, can the fans handle that?
Thanks in advance
Could 70c (max) shorten it's lifespan?
(sorry I just am extremely extremely paranoid)

I am seeing a lot of negative talk about third-party software to control fans:
Istat menu 5 is good.
It conforms to apple's SMC; this means that it will never allow the fans to go slower than what SMC is asking, thus your computer will be safe using this software.
In contrast I have a Macbook Pro fan controller for bootcamping Windows 7 called MacFanx64.exe (64 bit) that requires you to understand command prompt.
It's nothing difficult, you just need to make sure that you enter parameters properly.
The only way I see one of these damaging any hardware components would be if you accidently told the fan to spin faster than the max speed.
I would agree that for OS X you aren't going to really need this because the engineering on the SMC isn't terrible, but if you happen to have SMC screw up like it sounds like you had, there's no way to know it unless you feel it getting really hot like that which I'm sure isn't great for your MBP.
Therefore having a monitor system is helpful because you can see the temperatures constantly.
Now for Windows 7 bootcamp it's a whole different story.
There is something wrong with the drivers that control SMC for bootcamp because the computer will get hot fast even in idle.
I was marking temperatures around 60-70 C just in idle - the fans still stay at 2000 rpm.
If someone finds something better than MacFan for Windows 7 bootcamp let me know.
Moral of the story, if you pick a good third-party application you're not going to harm your computer.
Think of it like a second line of defense.
Last but not least, if you're still having this problem do an SMC reset.
Apple has instructions on how to do it, just note that you need to pay attention to whether your MBP has a removable battery or not when doing SMC reset.
Cheers

HT202179 MacBook Pro Fan is very loud overnight. How are they replaced?

MacBook Pro Fan just started to make a lot of noise.This is a MacBook Pro 15 inch 2.4/2.2GHz purchased June 2007. Is this something that most people can replace or does Apple need to fix it or is it time to get a new one base on age and potential repair cost?

Your Mac uses measured temperatures to determine fan speed in a feedback loop.
Racing fans are an indication that your Mac is overheating, or a temperature sensor is not working properly. Replacing the fan will not fix the problem.
Your appointment for an evaluation at the genius Bar of an Apple store is free, in warranty or out. There is no obligation to have them do any work for a fee, but if you choose to, charges are generally flat rate for guaranteed repair, no surprises.
If you recently replaced components, such a RAM DIMMs, with parts that do not have Apple-approved temperature sensors, that can also cause such problems.
