27'' iMac fan running very loud?

I recently had to have a logic board and a video card replaced under Applecare, (get it, I have always needed my iMacs fixed). I have 'Carbonite' installed as backup. My activity monitor (when Carbonite is running) is showing that Carbonite is really working the 4 cores of the processor. Between 75 and 99%. My fan NEVER ran really loud before on this iMac, or my last two iMacs. I have used Carbonite as a backup for the last three years. The reason for the logic board and video card burning up MAY have been that the fan did NOT come on.
I'm going through a lot of phone calls with Carbonite to see if they have any answers. In the meantime I'm disabling Carbonite. So far the loud fan is not coming on.
Does anyone else have the problem of a very loud fan running? And why do you think that is?

Hello, let's see some temps & fan speeds please.
Get Temperature Monitor to see if it's heat related...

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!!! ;)

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.

Hi Brandon: This is a shot in the dark, but check out the troubleshooting tips in the Apple article below.

FAN RUNNING VERY LOUD

I am wondering if anyone has had or heard of the fan in a 24" iMac suddenly running quite loud? My computer is a year old and today I turned it on and it sounds like a desktop DELL!! The fan is so loud. Is this an ugly monster rearing it's head? or is this a minor issue that might go away?
Please help.
Cheers

It probably means the computer thinks it is overheating. Maybe it is overheating. As Miriam suggests, intense computational activities generate heat. Possibly dust has accumulated on the inside, or where you are positioning the computer is blocking the flow of air. If the software that controls the fan is not working properly the default mode is to run the fan at full speed. Have you run disk utility to verify your drive to check all seems okay?
Alternatively the computer just thinks it is overheating. There are also hardware analysis tools that come on the disc with your Mac.
There's third party utilities that report temperatures, but Apple says you shouldn't reply upon these, and take your computer to a service center.
This isn't one of those liquid cooled CPUs is it? There was a post about one of those overheating recently and the guy found the coolant had leaked and left a puddle under his computer.

Mac Mini Fan Running Very Loud

Hello,
The other day whilst play Rome: Total War I noticed the fan on my Mac Mini (bought new in 2012 with fusion drive, quad i7 2.3GHz, 8GB Ram) was blowing a gale. I downloaded MagicanPaster to monitor the Mac Mini and this occurred every time I played RTW, or when I exported a file on iMovie. I know a bit about computers, but not anything about technical stuff so wanted to check that my Mac Mini was behaving within "normal" parameters. The MagicanPaster reported the following whilst exporting an iMovie file:
CPU
- 15% system usage, 58% user usage
- 260 Processes
- 1632 Threads
RAM
- 300MB Free
- 2.3GB Inactive
- 2.5GB Active
- 1.2GB Wired
Hard Drive
- Read 75MB/s
- Write 656 KB/s
Temperatures
- CPU 97oC
- Disk 32oC
The Temperature of the CPU is my biggest concern, but like I said I don't know if that's just what happens when using iMovie.
Thanks for any help,
Ashley

I have the same Mac mini as you do but with 16GB of RAM. Normally in a room with an ambient air temp of 41℃ the average temperature of the four CPUs is around 55℃.
You actually keep your room 'normally' at 105 degrees fahrenheit, the equivlent of 41℃ ?
No the room temperature is more like 74℉ but the ambient air sensor in the Mac mini "sees" a temperature of 41℃ in its immediate vicinity which is inside the Mac mini enclosure. 105℉ is more like the Outside Air Temperature during the summer here in Texas.

My Macbook Fan Is Running Very Loud...

My fan has been running very loud for the past week and I'm not sure whats wrong with it.

Welcome to Apple Support Communities
If the fan is working all the time, it looks like a sensor problem.
Run Apple Hardware Test > http://support.apple.com/kb/HT1509?viewlocale=en_US&locale=en_US Plug the MacBook Pro to its charger, choose your language, tick the box to run an extended test and start the test. If at the end of the test you see an error, copy it here.
It's probable that this is a sensor problem, but if the problem doesn't happen during startup, it would be a process which is consuming your CPU. Open Activity Monitor, select "All Processes" above "Show" in the toolbar, and order processes by CPU. Do you see any process which is consuming more CPU than the others?

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.

My fan is running very loud

My fan is running very loud...Not sure what the problem is..Does anyone have any suggestions?

If it is your fan, the cpu is working very hard.
1. check with Applications/utilities/Activity Monitor, <all processes> , click the %cpu column, what process is running more than 50%?
2. install the widget iStatPro (free), clik the Dashboard: iStatPro will let you see the CPU usage, the temperatures, and the fanspeeds.
If there is a process that is "eating" the cpu, in activity monitor you can quit that process. Check in System Preferences/Accounts Login Items tab, if it is there, delete it there. Restart the system.

One of my fans is very loud, while the other one is fine, is this an issue?

Hello there, Snake97.
The following Knowledge Base article provides a great step for fans running at full speed:
iMac: Fans run at full speed after computer turns on
http://support.apple.com/kb/ts1433
In order to correct the issue, reset the SMC. Your iMac should now start up and operate as expected.

My powerMac G5's rear fans are very loud?

Hi, I recently got a mint condition Dual 2.0 GHZ PowerMac G5. The computer boots perfectly, it's very fast even though it's got only 512MB of ram and so far, it has never crashed, I'm even posting my question with this computer, however, the rear fans are very loud, they're revving very quickly, and if I want to put it to sleep the fans are still very loud and it won't wake, I have to restart the machine. Does anybody how to fix it? I already reseted the PMU, I cleaned the entire computer with air, updated all the way to 10.4.11 since it had 10.4. Another thing I found was that when I opened the case to clean it, I noticed that a plug was loose, right near the ram. I have no idea where it should be connected or what is it for and I don't know if it's related with my problem, but I uploaded a picture of the cable to see if anybody knows where it should go.

Thank you for being quite helpful, and like you said, I checked the diagnostics on system profiler and I also got that it passed on diagnostics. I also checked my computer using techtool deluxe, it said that my CPU was working properly so I'm pretty much in doubt now. What do you think I should do next?
OK, your comment above in the singular is puzzling, and going back to your post with the System Profiler snip shows Number Of CPUs as 1. You should see the following, if both CPUs are recognized:
Machine Name:        Power Mac G5
Machine Model:        PowerMac7,3
CPU Type:                PowerPC 970 (3.0)
Number Of CPUs:    2
CPU Speed:              2 GHz
So the question is why is one of the CPUs not showing up? The system log listing points to a mismatch, which may simply mean that a thermal calibration needs to be run, but if the problem is only dealing with thermal calibration, both CPUs should show up in System Profiler. Since I haven't used Tech Tool since the days of Classic Mac, I am not familiar with how it reports things like a "missing" CPU, for instance.
Not sure whether we are dealing with a truly dead CPU here, a "wrong" CPU, or what. You can compare the EEE numbers against what should be compatible, for instance (see the DV Warehouse discussion of EEE numbers on any of the 5 CPU product pages, plus the listing of some G5 CPU modules for more information).
Finally, you can actually narrow down your model (there are two iterations with the same reported 7.3 designation) by inputting the serial number to the Chipmunk site model lookup and know for sure.

Follow the developers instructions for each app and uninstall. Then restart in Safe Mode and then restart normally and retest.
OS X does not need third party apps to run well, and WD's software is total garbage and should be ignored. Their external HD's are pretty poor too, the enclosures WD uses tend to create a lot of issues with OS X. I would recommend buying higher quality EHDs, something like OWC Mercury Elite Pro series.

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?

Your profile was way out of date so the updater I gave you will not be suitable.   This thread does prove the need to keep up to date.
The 4GB is sufficient for your apparent needs though it may be helpful to apply the updater below for the newly advised OS.   It may take some time; it is a biggie!
Mac OS X 10.6.8 Update Combo v1.1   Then check things out.
If that doesn't help check out the number of operations that are running in the background.   If you have the iStat Pro app located in your dashboard, that will help.   It's an excellent app - and free.   See if they're all necessary.
Apple - Downloads - Dashboard Widgets - iStat Pro
Almost certainly others will chip in soon but hopefully I've set you on your way.
