Cpu fan is extremely loud

Hello,
I have a 5,1 mac pro and recently my 2nd cpu failed me and i took it off.
After that i have extremely loud fun noiz on the cpu heat sinks, if both of them installed or at one if its alone.
Is that because i run it without CPU on B tray?

Without a working CPU in that socket, the measured temperature is out-of-range. To avoid melting your equipment, the fans will run at top speed when a sensor like that one shows out of range.
Those CPUs are readily available. Get another one, or upgrade both to a slightly faster one, to get your machine back to "normal".

My fan is extremely loud when i stream videos...

my fan is extremely loud when i stream videos...is this normal? My laptop is only a month old

It isn't uncommon that your fan should run when streaming videos, especially flash.
Is you laptop properly ventilated ? ----> If it's resting on the bed, cushion, carpet or some other soft surface that could be blocking the vents, or which doesn't allow heat to dissipate, your laptop will heat up more than usual, and hence the fan will have to run faster.
Is your laptop on a cool surface that is ventilated? (like a wooden table)?
Are you running Lion? Ever since I upgraded to Lion my fan is almost always running, video or not.

My MAC fan runs extremely loud when I use Safari. What can I do to fix it?

When using safari my Mac gets extremely loud. No flash content, no video. It can be sitting there untouched just with safari open and out of no where the fans kick in and loud. What can I do to solve this issue?

To remove a forgotten Restrictions passcode you will need to either...

GS70 Stealth Pro bought last month Fan speed EXTREMLY LOUD

i took a video of the sound speed
idk whats going on its extremly loud is very scary. Is there any way i can fix it my self? because i need the laptop
also if i send it to msi in calli how long will it take? for this to fix it and send it back

i do agree with darkhawk, your laptop has got an defected fan, what it sounds like is it's being pressed and that middle part of fan is forcing the fan to spin causing that sound and also wouldnt be suprised if the fan blades are scraping against metal cover above and under fan part since fans have 2 metal plates so yeah.

My MacBook Pro (Early 2011) keeps freezing, the fan becomes extremely loud and the laptop gets very hot, what can I do?

Hi there,
I would be grateful if any one could help me. I purchased my MacBook Pro 13 Inch in August 2011, it was the "Early 2011" version, which was shipped with Lion (I have now upgraded it to Mountain Lion last year).
Up until a few weeks ago, it was running fine. But recently my MacBook keeps freezing (A circular rainbow appears on the cursor), slowing down, the fan gets very loud and I often have to restart the whole machine. This usually happens when I'm running programs such as Safari, Preview or Microsoft Word
I only use my MacBook for university work so I only have Microsoft Office and iWork installed, nothing else. I've only used 19gb out of the 320gb available. I've also reseted my MacBook to its factory settings but that hasn't fixed the problem.
I've checked my AppleCare status and it says:

I was wondering if anyone had any suggestions to how I can resolve these problems, as it is stopping me from doing my work?
Many thanks.

Call Apple and make a appointment, backup your use data off the machine to a external drive.
Don't bother with TimeMachine if it asks, too long and likley be corrupted and unable to restore, just drag and drop your Users folder to the external drive.

I'm wondering if anyone else has had problems with their imac fans being extremely loud when running at slow speeds? When the computer heats up enough for the fans to run at higher speeds they quiet down. New HD fan was just installed.

I have an imac that I've had for a couple years. The fans have always been loud when running at the slower speeds. When the computer heats up enough for the fans to run at a higher speed the fans quiet down. I had installed SMC fan control after multiple attempts with Apple to get the fan issue resolved. That seemed to keep the fans quiet enough. I've never had a problem with overheating. Recently the fans were becoming loud again even running at the slightly higher speeds so I took it to my local Apple store and they replaced the hard drive fan. I got it back and it's now as loud or louder than ever!! And, now SMC fan control won't "stick." The fans will speed up, but then gradually go back to the lower "loud" levels. I'm at a loss as to what to do next.

Thanks jared,
I'm still dealing with this issue through Apple. Some time after I posted this, I contacted Apple again. They did start a case up for me, as I was experiencing the same behavior on two different machines, with two different versions of Windows.
So far it remains unsolved. I've logged iClouds for Windows on my desktop, which is brand new, then logged for awhile after completely uninstalling Norton Security Suite, depending on the Microsoft security for some time, and finally logged after I uninstalled iCloud for Windows, restarted, installed a clean download, and connected using a completely different test account, which Apple set up for me. None of this made any difference. Looking at the logs, it seems every 10 minutes, iCloudServices.exe creates a new TCP connection to confirm I'm using less than 5GB on iCloud, (which I am by a good margin, using less than 2GB), it seems this connection is not closed, and when the next iteration rolls around 10 minutes later, a new TCP connection is created. I come very close to having 6 TCP connections created per hour, until I restart my computer. This works out to... 6 x 24 = 144/day.
Perhaps the article you posted will shed some further light on this. I'm thinking seeing the state of the connection through netstats, at the least, could help.
For the last week, I've been putting a hold on further logging, as Apple wants me to create a new user account on one of my computers, install iCloud for Windows there, and log it running in the other account. This however basically means I cannot use my computer for a fair number of hours, and I've been busy enough with work the past week that I haven't the time or energy to afford to set this up and run it. I've had need of my computers too much for the past week.

Fan Gets EXTREMELY loud on HP-dv7-6135dx laptop

Hey everyone,
I love my HP laptop and this is the first issue I’ve ever had with it. Sadly, it’s like my child, and I love it so. I am very worried about it. In the past few weeks the fan has gotten ridiculously loud and sometimes it’s to the point that it makes the computer vibrate never mind being annoying. I went in the BIOS settings and changed the fan from being always on to on and off so it does shut off sometimes now. I've tried spraying some canned air into the vent to clean it and it helps a little then is back to loud shortly after. The fan probably needs to be replaced but seeing as my laptop is out of warranty I don't know what to do. I could take it to Geek Squad or a local PC repair store. Does anyone know how much a fan replacement on a laptop usually costs? Is it hard to do yourself? This is very distressing. I haven't had any issues with overheating yet as I always keep the laptop on a desk and I have an oversized battery so the laptop always has airflow beneath it. I downloaded a program called Speedfan and had no luck with adjusting the fan speed. I just really want this to be fixed and not cost me an arm and a leg as I am laid off. Can anyone point me in the right direction as to what I should do. The fan wasn't always like this as I said this happened not long ago.
Its an HP dv7-6135dx Notebook
It's product number: LW174UA#ABA
I am running on Windows 7 Home Premium 64-bit Service Pack 1
The processor is Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz
The GPU is Radeon (TM) HD 6490M integrated with Intel(R) HD Graphics Family Chip (switchable)
Thanks Alot,
Timothy

Tragetica,
The estimates given could be accurate -- it depends on where you, the quality of the replacement parts, from whom you order, whether you do the work yourself. I use HP parts and I order from HP; I have that option. The simplest approach is to call and ask for help if this option is available for you.
Contact HP
Here is a good resource on figuring out whether you want to tackle the disassmbly:
Disassemble the HP Pavilion dv7 laptop
Here is the Service and Maintenance Guide for the dv7:

YouTube is a great resource - Watch, watch, and look around at what is available. There are videos on the subject that can help you decide whether you want to do this yourself. Even if you do not do the job on your own, you will be better informed when you take in or send the unit for repair.
Remember that a key factor in any repair is the repair itself and to keep from damaging anything else in the process. Be sure you have backups - more than one set and more than one kind - BEFORE you do anything that requires you to take apart your computer or to send it to anyone else for repairs.
Because you are having issues with the fan, I would suggest it is important to have at least the Image backup of your system done anyway -- just in case you need it. That fan may quit working and you want to have a means of recovery.

Fan noise extremely loud since BIOS update; S430

hey there,
I have installed the new bios update; so I am running version 2.5 now. I have noticed that the fan is running more frequently now and louder than before, although I am not working on any demanding tasks. so, it is not unusual that the fan starts running very fast when I am just checking my mails.
Moreover, I noticed that the battery life decreased and I can hardly make it up to 3,5 hours. Normally, before the update, the battery could easily make it up to 5 hours.
Is there anything I can do about this?

Hey moritzmoritz!
I wanted to clarify which version of the BIOS you are currently using. I see you are currently using version 2.5 (released in Jan. 2013) of the BIOS, did you by chance mean the 2.51? The 2.51 was released Feb 6 2013, the date your post. I look forward to hearing back from you on this. Thank you!

When i watch videos or listen to music my laptop heats up to much and my fan becomes extremely loud

thats about it

Hi Miss_FayeFaye,
Thanks for visiting Apple Support Communities.
It looks like your computer has been scheduled to shut down automatically at a certain time. You can check this setting in the Energy Saver section within System Preferences:
Schedule your Mac to turn on, turn off, go to sleep, or wake from sleep at specified times. You might do this if you want to be sure your Mac turns off when you aren’t working and turns on before you come to work.
Choose Apple menu > System Preferences, then click Energy Saver.
Click Schedule, then select the options you want to use.
To schedule a startup or wake time for your Mac, select the “Start up or wake” checkbox. Choose a day or group of days from the pop-up menu, then enter a time.
To schedule a shutdown, sleep, or restart time for your Mac, select the bottom checkbox and choose the appropriate option from the pop-up menu. Choose a day or group of days from the pop-up menu, then enter a time.
See this article for the steps:

Satellite 2410-404: Screen is lose and the CPU-fan too loud

Hi,
first off: sorry for my bad english.
Now: I have several problems with my laptop:
1. The screen/monitor is lose and doesnt stand, so when I want to work with my laptop, I have to lean something against the monitor, so it doesnt fall to one side. Any solutions to this?
2. My Cpu-fan is really loud and I already opened the case and cleaned it, but every few days the noise comes back (guess its not rotating very well and contacting every once in a while some part of the computer) and i have to reopen and touch it some times till it works normally.
3. Also I have lost my Windows recovery CD (OEM Version) . Do I have to buy a new one if I want windows reinstalled?
thanks for any help

Hi
1. I presume the lid cannot stay in the right position because the hinges are a little bit loose.
2. It sounds like something wrong with the fan rotation. In such cases the easiest way is change the fan.
3. You can purchase the Recovery CD form the Toshiba service partner in your country. Its not very expensive.
But you can also install the original Windows OS on your notebook and then you can install the Toshiba drivers and utilities. All Toshiba stuff you will be able to download from the Tosh driver page.

CPU fan on new 27"

Hi, I bought an 27" iMac from Apple 2 1/2 months ago, and most of the time it's very quiet. But sometimes the CPU fan gets very loud and the rpm is over 3,000. When it's quiet it's usually in the
938-940 range. I did a hardware test and there were no problems. Do I need to bring my Mac in, or am I missing something?

{quote:}1. Get a can of compressed air and make sure the vents on the bottom of the computer are not clogged with anything (do you have pets?).
2. Do the same for the circular vent behind the pedestal/base (above where the power cord enters the computer)
3. Do the same for the vent slit at the top of the back of the computer.{quote}
I would not clean the dust from my air intakes in that manner, because it will just blow the dust deeper into the iMac!
A better solution is to shut the iMac down, stopping the fans and then gently vacuuming out all the air intake ports.

The fan on my brand new Imac Quadcore is blowing extremely loud. Is this normal

The fan on my brand new Imac Quadcore is blowing extremely loud. Is this normal?

I have the same problem on my 2010 IMAC 27" I7. Even if the mac is running at idle it occurs. It was already at the apple store for repair.
Later they told me, they found nothing with the hardware test so its not their problem?!!!
the activity monitors shows also nothing special, even the cpu's are at idle. No streaming or rendering, just working on the web or some normal documents...
I runned smcfancontrol to check whats going on. It seems that the onboard temperature sensor is measuring wrong instantly so they SMC thinks, its to hot/or not and then spinning up the fans to full power.
SMC reset is not really working, or just for some hours.
Can anybody else help?
Thx

The Macbook Air fan is always working extremely loud? What can I do?

What can I do? The place around the fan gets extremely hot? The fan is constantly running?
Please help me

There are any number of possibilies... you could have problems with runaway applications, causing your machine to overheat and setting the fans off, you could have bad fan sensors, etc.
Open Activity Monitor (Applications>Utilities) and see if you have any apps that may be hogging the CPU. Call back.

Satellite A300-1DB CPU Fan is annoying, too loud

Hi all,
I bought a Toshiba Satellite A300-1DB today in a German (580 Euro) and i really like the notebook design and performance, but there is one big problem I can't bear anymore (and I just used it for 2 hours).
The CPU Fan on the left side of notebook is so annoyning: Even if I keep the notebook idle (CPU activity is very low, just under 10% and 1 gb ram used), the CPU fan keeps spinning for one minute really really loudly.
After that there is silence, such a beautiful silence.... for 2 minutes. And then the whole procedure starts over and over again. Just cold air comes out.
Thats drive me crazy, the CPU Fan in the idle modus is louder than my other Satellite A210-106 Turion X2-52 L with full CPU activity. I wish to have a CPU fan that keeps spinning in a low sound.
Do you have any ideas how to control the fan????
Otherwise i must try to replace it with another Notebook (I hope that they allow that, unfortunatly it isn't a Internet shop where you can send it back until 14 days)
Regards,
Dieter

I have managed this successfully using balanced power plan and using Battery optimized option for Cooling method. This setting you can find under Advanced power settings > Toshiba Power Saver utility.

CPU FAN SO LOUD!

So after installing all my new pc parts (FX-8350, MSI 970 Motherboard, GTX 750ti) everything is working as it should, but the CPU fan... (CM Hyper 212 EVO)
everything is default on the motherboard but ive put my ram speed to 1866MHz but that's not my problem. my problem is that when I'm playing BF4 (or anything CPU intensive) obviously the CPU is going to heat up right? but when it's under load, about %70, the CPU fan will be spinning at about 400rpm, at %70 load still but then suddenly it boosts itself right up to %100, and it's so loud! I've tried setting a fan curve on the hardware section of the bios,(as temperature increases, CPU fan RPM increases) but it just doesn't do that! and also while it's under load the cpu fan will be at %100 then drop back to 400RPM, is there anywhere that can tell me how to use the fan curves? thank you!
*SHORT*
CPU fan curves not working

Hi,
Try to change (within BIOS) from "Smart Fan" to manual control and set minimum value of 25% and max of 100%. Then you should be able to control fan within Windows using Command Center and if you need 100% you will set to it, else you can have it lower.
What is the actual CPU temp when it hits 100%?
