MB 13" late 2007 - fan running really loud

Hi guys!
I've tried to find a solution to my problem around the web, but I didn't find anything what could help. My old MacBook from 2007 started to get pretty loud recently. What I realised, fan is turning on while I'm running internet browser (doesn't matter, Safari, Opera or Chrome). But when I watch a movie, even in 720p, the fan is quite. I don't have much apps on my MB, and I try to run CleanMyMac from time to time.
Is my MB just old (that is a pretty obvious answer), or I can do something to fix it?

There could be a few things going on to cause the symptoms, the fan and likely excessive heat.
If the hard disk drive is relatively full and has little or small available free space, the computer may be looking for places to put swap and temporary files the OS uses, to include those when the OS uses free space as Virual Memory. This would mean more read-write cycles to the hard disk drive, if there isn't enough RAM.
Also if the hard disk drive is getting older and worn, it may be slower and the processor among other things are adding up and generating heat so the fan runs more. An early model MacBook may be a candidate for a larger capacity hard disk drive, & if it doesn't already have it, an upgrade in chip RAM capacity to the max it can use.
There may be a reset, such as SMC (system management controller) that may help. In some cases, though the NVRAM/PRAM reset helps. I had to try both on my MacBook when it seemed the processor cores were alternatingly hotter than spec but without a load. In this case, I suspect my MacBook may need the thermal couple to the heatsinks removed and new thermal paste applied, so any heat may be transfered faster. I used a free utility called 'temperature monitor' that includes temperature monitor lite, a download. It works OK once you figure out the settings, and choose to install extra stuff for intel cpus.
So there are things that could be done, depending on the cause of the symptoms. Going through the long way may include unproductive steps when 'trial & error' is involved, so hopefully there is a shorter recipe.
Good luck & happy computing!

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.)

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.

Athough there is not much usages in the CPU , but the Fan runs really hard and loud , and i've ready try to reset the SMC ! i don't know what to do !

I suspect you didn't reset it right.
Turn off the machine, let it charge up and then try the SMC reset again.

Imac shut off and the fan is really loud...

I have an iMac 27" i7, 16 gb ram. The screen randomly shut off and the fan became really loud. Tried turning it off and back on, but still did the same thing. Tried resetting the PRAM, heard the chimes, but then did the same thing. Is it overheated?

Check it. Install an app like iStat Pro to check the temperature, and post it here. There are different temperatures (CPU, hard drive, graphic...). If you want, just take a screenshot of the widget (holding Command, Shift and 4 keys, and selecting the widget) and upload it here, pressing the photo icon at the top of the reply box.
Apart, you should run an Apple Hardware Test extended test, to check if there's any problem with the iMac > http://support.apple.com/kb/ht1509 If, after running it, it shows an error, copy it here, because the Mac has got a hardware issue

Satellite A300D - Fan running very loud and notebook is getting very hot

I was wondering if anybody could point me in the right direction as what to do with the overheating problem i currently have with my A300D. I have had the laptop for under a year so it is still under warrenty but i am not sure where to go or what to do in order to repair it.
The problem: Around two months ago I noticed the fan running very loud and also the laptop becoming very hot. Now it runs so hot the laptop switches itself off completly. The heat being fanned out of the laptop is so hot! burns your my infact.
Has any one any advice they could offer me.
Thanks
James

Hi James
You wrote that you have the notebook under a year so my questions is did you already clean it?
The notebook should be cleaned every 3-4 months and I do this every 3 months. Every time I do it Im wondering how much dust comes out and after this procedure the notebook is a lot of cooler.
Here is an interesting Toshiba article about this:

Compressed air spray is really useful and you should check it yourself!!! ;)

How can i download an older version of pages for late 2007 macbook running osx lion

i would like to download an older version of the pages for late 2007 macbook running osx lion

If you previously bought Pages from the Mac App Store, click here and follow the instructions, or go to the Mac App Store main page, click on Support under Quick Links, contact Apple, and see what they say.
If not, buy an iWork 09 DVD from a source such as Amazon or eBay.

Why is my fan running so loud?

I purchased my 13" macbook pro about 2-3 weeks ago, But have noticed just recently my fan running quiet loud and constantly. I have done two smc resets that didn't change anything, checked my activity monitor to find nothing wrong, and checked my exhaust rpm and temperatures which were perfectly normal. Does anyone have any other information that would help me fix this frustrating problem?

My iMac's fan runs quite loudly.

I only got the computer yesterday from Apple, but it was refurbished. It's an iMac 21" 2.7 1TB.

When you say that the 'fan runs quite loudly' do you mean that the fan is making an unusual noise such as a buzzing or clicking sound, or do you mean that the fans sound like they are running at full speed?
If the fan is making a buzzing or ticking noise then that could indicate that something is touching or rubbing against the fan. If you just purchased the iMac then I would contact Apple to arrange for a replacement.
If the fans sound like they are running too fast then it could simply need an SMC reset. To do this, power down the iMac and then disconnect the power cord for ~15 seconds. After 15 seconds plug in the power cord while making sure you don't press the power button. Here's an article that provides additional information on this condition and why it occurs.

It's fan sounds really loud...should i be worried?

I'm completely confused. The iMac is hot? It's cool? I don't think we know yet it's a G5.
Anyway, if it's an iMac G5, for the fans try an SMU reset.

If it's not an iMac G5, Google "SMU Reset" for your model.

MacBook fan running very loudly

I have been having issues with my MacBook overheating and causing the fan to run very loudly (so loudly I can't listen to music or watch videos on it very well). I have had the motherboard replaced twice this year alone by Apple and I still have coverage till November of this year. They told me if I keep it on a flat surface (like a desk), the problem shouldn't keep happening. More times than none, I only have one application running like Safari or Firefox with only one page open and still the computer is incredibly loud. Any suggestions? I really do not want to take it out to a retail store again unless I can get a new MacBook out of it since it'll be the third time the motherboard has been replaced.

Mac fan running too loud after update

I have a Macbook pro 13". (mid 2012)
Memory: 4 GB 1600 MHz DDR3
Processor: 2.5 GHz Intel Core i5
Storage: 500 gb
After updating to Yosemite 10.10, my macbook pro's fan is running too loud and producing a lot of heat. I reseted the SMC several times but it didn't help. Surprisingly, The fan also runs loud even if only 1 application is open.
Please advice me what should I do.
Thank you in advance!

I have the same model and I've had the same problem for a few days. I didn't really have problems with heat, but my fan was going crazy even though I was just browsing the Internet. Maybe you're logged into iCloud and have some activity going on. What worked for me was going to:
1. System Preferences
2 iCloud
3. Uncheck things like "Keychain", "Find my Mac", etc. (things you don't need/use)
For me, I unchecked everything and logged out of iCloud. After several minutes, my fan is super quiet and not acting up! Hope this helps.

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.

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.

Computer is unresponsive and fans are really loud.

Last night I walked into my room to hear my G5's fans blaring loud. I tried to move my mouse and the entire screen was frozen. I didn't know what else to do but to hold the power button in to force shut it down. I let it sit for a few minutes and then powered it back up. It made it all the way to my desktop but would not load my icons and the fans started blaring again. So I forced it shutdown again. After powering it back up 2nd time it won't go pass the grey apple screen. The fans are blaring loud again.
What is causing this and how can I correct it. I am able to get online via my Macbook Pro but I really need to get to the bottom of why desktop is acting crazy!!!
Thanks!!!

No.
That is why I always advise,
CLONE and run Disk Warrior on clone, then test that out.
And in the past and for PowerPC, Applejack.
If it is with cache files, those are of course temp files, and which SD doesn't copy, some of which now 10.6.x is better at clearing during a SAFE BOOT but for which people use to use AppleJack (and Maybe Leopard Cache Cleaner) and since we are talking PMG5 10.4/10.5 PPC.
To check all the files, TechTool Pro 5.x or Drive Genius 3 (never used DG, never needed to).
Have multiple backups.
All of these system and disk repair and maintenance? mostly so you can mount and backup any files you need to, and then proceed to restore from good backups.
Usually, people are lucky and they can continue to work. Disk Warrior used regularly and for preventative maintenance (rebuild but also scan files and folders).
HFS+ is not reporting errors (they can be just weak sector, more retries on read) and even ECC is not perfect either at stopping memory errors.
