CPU Fans Really Loud

I have a Unibody Macbook Pro 2.4 GHz w/ 2 GB ram. When I watch streaming video using flash (either through a browser or with adobe air program) my CPUs get slammed and the temp shoots up on the CPUs to over 80 degrees C. Both fans rev up and usually run at about 4000 rpm or higher. They are quite loud and since I am a law student trying to watch video in class this is severly annoying.
Have other people experienced this? I had a Powerbook G4 that was never this loud. the computer is obviously still under warranty, should I take it in?

It sounds as if your fans are reacting exactly as they should to cool your computer. If the sound seems excessively loud, it wouldn't hurt to take it in for evaluation. A chill mat might also help.
Good luck!

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.

MacBook air running slow and fan really loud how to fix?

MacBook Air running slow and fan is really loud and using lots of battery. How to fix?

Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

Fan really loud

My son's imac has been shutting down on its own and not wanting to start up. Then it'll start up by itself and the fan is really loud. I followed the steps to reset the SMU but it didn't help. (turned off computer, removed all cables, including power cord.... waited 10 seconds, held in power button and put in power cord at the same time) I don't have the extra warranty protection right now, because the lack of funds won't allow right now. I'm planning on purchasing it in a couple weeks. Anybody got any suggestions? HELP!

Welcome to Discussions - Apple Care has to be bought within one year of the original date of purchase, so you had better do it before then. If you have a G5 iMac, it sounds as if your power supply unit is faulty, see if you qualify for one of Apple's Repair extension programs.

HP DV7-7010US FAN REALLY LOUD AND BATTERY NOT DETECTED..

Hi everyone, I have an HP-DV7 7010US, I got the laptop just about a year ago and recently the fan will spin really loud, like a roaring sound will come out and it will make it really uncomfortable to even use the laptop. I called the HP support and my warranty just ended a couple weeks ago, so I was wondering if anyone knew any solution or had any guides on how to DISASSEMBLE this laptop so I can get a good look for myself. I have tried to look allover the internet and there are no guides or videos on disassembling this exact model... someone make one please! I cannot get 1 last screw out and not sure on how to pop out the keyboard like the previous DV7 models.

Well, the keyboard DOES come off before the top cover because there is one screw hiding under there that connects the top to the base ! (Guess which screw is NOT going to be re-installed !)
Step 4 of the keyboard removal procedure say "Press on the back of the keyboard through the opening in the optical drive bay until the keyboard disengages from the computer." Well that opening is covered by the numeric keypad ! Use a small, very thin bladed screwdriver to pry up the edge of the keyboard. It will pop out.
The base part number has been superseded. From the HP Partsurfer Part 681970-001 is no longer supplied. Please order the replacement, 707999-001. I do not know what differences, if any. there are between the 2.

Fan really loud after coming in from the cold

I came home from school today and left my backpack in my car which had my MBA in it to talk to my neighbour for a bit. It's approximately -22 Celsius where I live right now. When I came inside, I woke up it up, as it was previously sleeping, and it's fan (or at least that's what I think it is) was really loud. Ever since I got it, I haven't heard the fan once, and I was horrified when I heard it, so I quickly turned it off. I later found out that I have to let it warm up to room temperature before turning it on. It's been about 2 hours now and I just tried to turn it on again, and I'm still hearing the fan. What should I do? I'm worried because I don't want to harm my MBA, but I also need to use it to work.

Ooh, you should never do that, you need to let your macbook warm up to room temp. before turning it on.
you risk condensation forming inside a rapid warming macbook as the fan shuttles WARM air in the room over the COLD logic board
its not the fan you should worry about, its doing that and causing condensation and corrosion to form from quick temp. fluctuations inside the cold macbook.
DONT do that again, it leads to corrosion.
FAN NOISE:
A: you notice it more in a quiet room (the typical case) which is normal, all is AOK
B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.
C: fan rotor is going bad and making a whirring or buzz noise (rare).
D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)
A and D are normal
B and C are not.

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%?

Issue: bootcamp gaming fan really loud

Computer: MacBook Pro Retina Display 15" (2013)
When I play game under BootCamp Window 7, my fan becomes very loud.
Is there any way that I could reduce the fan's sound?
Will it help if I have an external fan (regular home standing fan or usb fan) that cooling the computer?

leonhart1981,
if your fan is becoming very loud, it’s because it’s doing its job — your Windows 7 game is creating heat inside of your MacBook Pro, and your fan is doing what it’s supposed to do to prevent your MacBook Pro’s components from baking. An external fan is not likely to significantly reduce the noise of your internal fan, unless you’re saying that you prefer the sound of your external fan to the sound of your MacBook Pro’s fan — the need is to get the heat outside of your MacBook Pro’s case, and your MacBook Pro’s fan is a far more efficient tool for that job than an external fan would be.

Fan really loud gaming

when playing games (any really) on macbook pro 13' early 2011, my fan kicks in and starts going crazy. even during relatively easy games such as minecraft. i was just wondering if this is normal? oh and my hinge is really loose, if i touch it (lightly) it will almost crackle and pop, just wondering if i could fix this?
cheers in advance (hopefully) :]

Fan is most likely normal, happens to me too.
You might want to have the hinge checked at an Apple Store or Authorized Service Provider.

Is the Time Capsule suppose to sound like a whirring fan - really loud all the time?

My newly purchased time capsule is sounds like a loud fan! Is that normal?

No. It should be nearly whisper quiet when operating. It may be that you have a defective unit and I would recommend returning it for a replacement.

My fan is running really loud, low cpu (i think?)

My fan has been running really loudly for a day now. I have tried turning it off and on again, putting it to sleep, cleaning out the dust.
On my activity monitor "opendirectoryd" is running at 94.5 percent and I have no idea what that is and if it is causing the problem?
I have looked at answers on other forums for the same thing but none of the remedies have seemed to work. Can any one help please?
I also put in some code that was on a different forum into 'terminal' but have no idea what the results mean. I have copied it below:

Hi..
Try Resetting the System Management Controller (SMC)
As a rule it is not a good idea to run Terminal commands unless you have a better understanding of what the results should be.

The fan gets really loud sometimes

I just bought my Mac a couple weeks ago, not more than a month ago, and I haven't really downloaded a lot onto my computer. But sometimes the fan comes on really loudly, like it's having a hard time cooling the computer. Granted this happens usually when I'm on a site or using a program that is graphic intensive, but it only started doing this sometime this week. Could there be something wrong with the computer?

Your MacBook is behaving as it should. The fan will come on when the CPU is working overtime.
You can run Activity Monitor in the background and see what processes are consuming CPU cycles when the fans come on.
It is Abode Flash more often than not on a website that gets the CPU working hard and the fans going.

Really loud Fan

Hi,
I have a 2010 MacBook Pro and bought it in the summer of 2011. Last august the fan started making really loud noices. I have checked my CPU usage and Itunes was a laggy factor which was resolved when i shut itunes off. I am still wondering why my fan goes crazy. I have also reset the SMC.
Could there be another way to stop my fan from goingg so hard?
Thanks,
Slengel5

Run an Apple Hardware Test. Your MBP may have a bad sensor:

You may have to start it with the OPTION and D keys.
Ciao.

Fans running really loudly?

Recently when i was using my macbook pro, the fans seemed to go into overdrive and started making really loud noises, the noises sounded like it was rattling slightly. I didn't have any strenous programs running, just pages and google chrome, but the sound persisted until i put my computer to sleep, then it stopped. Right now it is queiter, but what should i do to avoid this in the future?

If your fans are going crazy when you aren't loading the system, then something is wrong. Try an SMC reset. And to make sure some background process hasn't gone wild, run Activity Monitor (from Applications > Utilitites) and select All Processes - anything suspiciious running over say 10%? (You can sort by CPU% by clicking on the column label.)

Does anybody have problems with the Macbook Pro Retina 15' fans being really loud even when playing flash games like candy crush or tetris?

Hey guys,
So after a few months of using the MBP 15' Retina, I've discovered that the fans are incredibly loud even when playing flash games like candy crush or tetris.. are any of you guys having the same problem? Like all of a sudden from be quiet to unbelievably loud just as the games load. So yeah, hopefully someone has the same problem as I am having.
What I was thinking was that the MBP Retina 15' is such a beefed up laptop, it shouldn't require that much CPU to run flash games that are not even THAT graphically intensive to which making the fans that loud..
Thanks!

Believe it or not, Flash REALLY isn't the issue.
It's hardware makers making devices with less processor performance and requiring software makers to fit into a certain requirements of such. Namely iPhone, iPods and iPads.
Flash is designed to give a lot of features and work across many operating systems, browsers and platforms as a write once solution.
Flash has a certain level of processor performance requirement, which hardware makers like Apple want to build less powerful machines using less expensive processors.
Apple has removed Coverflow 3D effects from iTunes and discontinued the 17" MacBook Pro, leaving only the 15" as having a more powerful 3D capable graphics capability.
So Apple is obviously on a anti-heat/performance quest as they further thin up their hardware, trying to kill Flash by punishing Mac users who want to run it.
Flash runs without a fan sound on my older Mac with dedicated GPU and older OS X verison, no sweat.
Head to your System Preferences > Energy Saver and if you have it, uncheck Automatic Graphics switching, this will use the dedicated GPU and shorted battery life, but if your on power should reduce the heat and fan noise.
Another option is to use SMC fan control and set the fan default speed slightly faster, this will keep the machine slightly cooler and not trigger the higher fan speed as often.
If your running 10.8, you will need to System Preferences > Security > downloads to "Anywhere"
SMC FanControl is over at MacUpdate.com.
