Fan runs loudly and upgrades

So mac isn't really famous for having upgradeable products, but is there anyway or anywhere where I can change out hardware on my imac? I have a 20" G5 and I use it for Photoshop and Z brush and it works fine for that, but if I play a game the game play tends to jump. I'm not great with computers and I'm new to mac so I don't know if or where I can change the graphics or video card.
Also, the fan seems to run really loud at times? Does is seem this way with anyones else? It's done this before and I had to get the power supply changed... twice.

See if the following Knowledge Base Article is of any help:

Will running games that make the fan run loudly and the computer heat up damage my machine?

On my Macbook Air running Yosemite 10.10.3, with 4 GB RAM, 251 GB storage (170 GB free), a 1.6 GHz Intel Core i5 processor, and Intel HD 6000 1536 MB graphics card, when I play games such as Batman Arkham City, I experience very smooth gameplay with high fps. The only thing that worries me is when I play, the laptop heats up very much and the fan runs pretty loudly. Even with old, less intensive games like GTA SA, the computer gets pretty hot and the fan runs loudly. Is this damaging the computer, or can I continue to play these games?
Thanks.

Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost. When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.

Finder makes fan run loudly and continuously.

I've had my MacBook for only a few months now and I am having a problem with the fan. It starts running loudly when I am doing simple tasks, such as viewing a webpage which contains no flash, video, or similar content. The fan does not stop running unless I put my computer to sleep or restart it. I have found that by relaunching the Finder, the fan almost instantly slows down back to its normal state. This concerns me as this has been occuring more frequently over the past two weeks. Is there some sort of fix to this instead of having to relaunch the Finder every time?

Fan runs loud and continuously

Hi- The fan on my Macbook 2.1 Intel Core 2 Duo 2.16 GHz runs continuously and loudly from about 3 minutes after booting up. Activity monitor shows nothing unusual, only Firefox and Activity Monitor using any CPU (very small percentages). It has been a noisy fan for awhile, but used to come on only after prolonged use. Any suggestions will be welcomed. Thanks -Howard

If you have not already done so....reset the SMC....

NEW HARD DRIVE - FANS RUNNING LOUD AND RED LIGHT

I've just installed another hard drive in the lower bay of my G5 1.8. I took one drive out and inserted the new one, leaving the original hard disk with the operating system on where it was.
As soon as I pressed the "on" button the machine powered up but with the fans on very loud and a red light on inside the machine.
The G5 starts up fine. The new hard drive is recognised.
Any ideas what's gone wrong as it wasn't behaving like this before?
Thanks in anticipation

Hi gravenors, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
You could try checking that the clear plastic air deflector has been replaced correctly.
If it seems to be in place, but the fan and red LED are still on, please post again - as there are further things to try.

Mac mini Intel Core Duo fan very loud and runs at high speed all the time.

I purchased an "Open box" Mac mini Intel Core Duo, 1.66Ghz, 2G ram, 80G HD and SD a few days ago from Fry's.
It runs beautifully except the fan is very loud compared to any Mac my family has ever had. It is so loud that we were thinking of putting it under the desk.
The fan runs constantly, and I mean all the time, at a high speed. You can really feel the air coming out the exhaust vents. The case is always cool to the touch as is the exhaust air.
My aunt bought a similar Mac mini (But only 512Mb ram) the same day. Her's is very quiet. The case feels just slightly warm, not unlike other Mac mini's I've seen.
Should my Mac mini's fan be running this way?
Thanks,
llulua
BTW: The "open box" was sealed with a Fry's label and it said that this had a new warranty. Yet, checking the serial number, it said that it had about 260 days left. I guess Fry's is backing it?
Also, someone told me that perhaps the main wire from the fan to the logic board is disconnected.

eMac 1Ghz, iBook 500 dual usb, Mac mini 1.66Ghz Intel Core Duo 2g ram Mac OS X (10.4.8)

Since you have 2 gigs of memory, my thoughts are that when the party (Fry's or the origianl purchaser) upgraded the memory, they neglected to reattach the wire at the front of the Mini under the IR receptor at the right front corner that regulates the fan speed. This wire must be unattached in order to upgrade the memory, and is probably why the original person brought it back, because of the fan noise resulting from failing to reattach the wire. If that wire is left unattached, the fan runs continually at high speed to protect the CPU and system in general. If you do not want to use a putty knife to open the Mini, take it back to Fry's and ask someone who is Mac savvy to open it and reattach the small plastic receptacle at the end of the wire into its socket at the right front of the machine. When I go to Fry's, I am always concerned because the employees allow people to pry keys off of the Apple notebooks, so don't expect that their employees to know or care about anything Mac.

Imac (Intel based) fan runs continuously and loudly.

Have done a SMC reset, and the fan is still running loudly and continuously. Only 1 application open - firefox. This has been an ongoing, continuous problem.
Thanks in advance for any help you might offer.

Have had the same problem .. have reset the PRAM & SMC, doubled the amount of RAM. Fans runs & Activity Monitor shows most of RAM is used up with nothing open. Running Snow Leopard 10.6.8 on a Mac Book with 4g of RAM, Apple Support showed no hardware problems. ????

Mac Mini fan running loudly after Safari upgrade

Mac Mini 2GHz is around 2 months old. All been fine until yesterday. When running Safari (it seems) and not necessarily heavy usage fan starts runningvery loudly. In the previous 2 months NEVER heard the fan or at least it's been very quiet, so am quite concerned. It appears that this has coincided with updating to the very latest Safari release 3.1.1.
Anyone else having similar problem and/or advice?
thanks
D

The new Safari release supposedly has some issues with Flash media files and with Windows Media files -- and will require updates of the helper programs that display those formats.
Does the fan run loudly when you visit sites with such files? Or does it also run loudly if all you visit is sites with no video files on them?

XServe fans running fast and loud

Good morning
I have searched the information base and tried a few suggestions without success. Hoping for another solution here.
I have an Intel based XServe (2008) (OS 10.6.8) whose fans are running faster (and therefore louder) than they have previously. This follows on the heels of a power outage (two of them actually) here at school, though the server is behind a UPS. The system identifier light is also blinking in a particular pattern - 4 flashes and a pause repeating.
The server is up and running, teachers are connecting to it just fine, the RAID is intact and online, the drives all look good according to Disk Utility. So, functionally, everything looks OK - the fans are just running faster and louder than before - noticibly louder than the other Intel XServe in the rack. The server is at the top of the enclosed rack with a space below it as it has been for the last 4 years.
This summer I took all the XServes out of the rack, opened them up, and blew the dust out of them (including a moth - truly a bug in the system), so the all the airways are clean and clear.
I have tried the suggestions I could find on this forum:
     restarted a bunch of times
     shut down and disconnect everything (including power) for a period of time
     reset the PMU/SMC or whatever it is called doing the front panel buttons with the blue lights on the lower row
     reset the PMU/SMC or whatever it is called by holding down the power button while disconnected from power
I have installed iStat Pro and the temperatures are averaging around mid- to upper- 30°C and the fans are running around 3000 RPM . The temperatures aren't signifcantly different that the other XServe, but the fans are running about twice the speed.
I had to reformat the RAID earlier this weekend and copy over the data files from backup and reassign permissions, but the server was running quietly after that was all finished. It seems to be post-powerbump that the fans became noisy.
Sorry for the long post, but I tried to include all the pertinent information. I would have tossed in photos and videos if I could have!
Any suggestions would be appreciated.
TIA
Greg

Did a little more searching about setting up LOM on the XServe and I think I have it figured out now.
I assigned a unique (different) IP address to Network 1 in the LOM dialogue box in Configure Server menu of Server Monitor since I only have Ethernet 1 enabled and linked to a switch using a unique (different) IP address for network traffic between the XServe and my clients.
I can now see (via Server Monitor remotely) that I have a dead blower in my fan array which, upon closer inspection, is also evident in the iStatPro display (one fan running at 18 RPM). Hence the blinking system identifier light and the other fans running faster and harder (and noisier).
Oddly enough, I have a replacement fan array in a box of XServe spare parts. I now have a weekend task.
Thanks for all the information to be found and the people participating in this forum. Love it.

Is it bad to have the fan running loud all the time

the fan on my macbook runs loud and long at times. is this bad for the machine?

Is it possible to have 2 threads running at the same
time at different times eg 1 repeats every 20
miliseconds and the other 40 for example. Yes.

Macbook Pro fan running constantly and CPU running slow

So, I have a Macbook Pro 2010 2.3 i7 that has started running really slow and the fan is running constantly.
In activity monitor it shows a kernel_task running constantly at around or above 200%.
I have tried all the regular tasks. PRam reset, SMC reset and nothing seems to fix it.
I have also tried a system reinstall to no avail.
Maybe I'm on the wrong track, but from what I have read, the kernel_task might be trying to slow my CPU down because it thinks it is being overworked?
Maybe the fans are also being activated because it thinks the computer is too hot?
Anyway, if anyone has any idea as to what I can do to figure out what is going on, let me know. Thanks

My fan makes loud and very strange noises.

Hi again,
My fan makes loud and very strange noises. Is there any cure for that?
Thank you!
Markus

Hmm... that is strange. There are a couple reasons that I can think of.
First, go to System Preferences -> Energy Saver -> Processor Performance. See what its set to. If it is currently set to Highest, your fan could be going more often. Turn it down to Reduced or Automatic. Note if there is any difference.
Secondly, are you all up to date on software updates? The last step was to see if it was a software issue. If it isn't, then you probably have a defective fan. AppleCare?
Now, you would open your PowerBook. Look in the Apple docs (Support - Manuals) to find how to do it for yourself, or take it to a shop or Apple Store and have them do it. Safest option.
Look at your fan. Has it come free of the anchor and is hitting against the wall or fan surround?
Lastly, try keeping the PowerBook in a open, ventilated area. The fan will power up less if the computer stays cooler. For a possibly irritating but possibly helpful option, purchase a product that lifts the PowerBook off your lap or desk. I think Rain Design makes a good one.
Good luck!

15" MacBook Pro runs hot, fan is loud, and incredibly low battery life

My 15" MBP was bought in March or April (can't remember) from Singapore Apple Store. Here are the stats:
MacBook Pro 15-Inch, Late 2011
Memory 8 GB 12222 MHz DDR3
Software Mac OS X Lion 10.7.5 (11G63)
Also I'm using about 1/2 of the available 750 GB of storage.
Here's what's up:
1. The fans boot immediately after the computer is turned on and never stop, making everything much too loud...like a plane is taking off or something.
2. The computer is WAY too hot. Right now I'm running Astrill, Chrome, Activity Monitor, and System Utility, and when I put my hands on the thing it feels like my fingers are going to melt.
3. The battery life, even at a full charge, is about an hour overall, which ***** for so, so many reasons.
Here's what I've tried:
1. I took it to the Shanghai Genius Bar, but I think that the language barrier is impeding my ability to really say what's wrong. I backed up, and they wiped the hard drive, re-loaded the OS and put all my old stuff back on the computer. They also deleted SOMETHING from the Preferences part of the library, but I don't know what it was. Everything runs much faster now, but the fan, the heat, and the battery are still having their issues.
2. I've checked the "all processes" CPU usage. There's nothing unusual (as far as I can tell), so I'm at a serious loss as to say why the computer is running so hard. Even with all the processing running as you see below, the fan's still blasting and I've lost 50% battery life in the past 40 minutes.
3. I've tried the fix that requires deleting com.apple.desktop.plist and com.apple.desktop.plist.lockfile. It changed the way the desktop looked and absolutely nothing else.
PLEASE, PLEASE, PLEASE help me! I'm a graphic designer and often run the CS6 Suite. (Currently, however, I am NOT running any Adobe programs and I'm still experiencing the problems.) It's really important that I am able to run Photoshop, Illustrator, and InDesign at once, and it CAN, but with the heat problems I'm having without ANY of the graphics stuff running, it worries me.

Just took another look at iStat Menus (I've only had it for a couple of days - I used to use the old iStat Pro widget) and it seems as if you can make fan speed defaults and use them instead of relying on your MBPs sensors to take care of the fans... see...
Might want to use that 'medium' speed (there by default as I know I didn't add it) and keep an eye on your temps. If you start heating up to much, go back to the 'Default'.

Updated to OS 10.7.3; fan runs constantly and battery life dropped to under 2 hours when 100% charged. How do I get back to 10.7.2, I don't have a backup prior to this upgrade. This is a newer Macbook Pro 13", no modifications.

Help! This new version of Lion is making me miserable. The fan runs constantly, the computer is hot and battery life has dropped to under 2 hours on a fully charged battery. I updated yesterday, nothing but misery today. Even running the mail program alone make the fan run like I have everything open. Using Pages, iPhoto, and iTunes simultaneously makes the computer blistering hot.Yesterday, I could use all three without any trouble. Any suggestions to either jettison 10.7.3 or how to fix without any expense? I haven't modified this computer at all, it is as it came from the box in August 2011: 2.3 GHz Intel Core i5, 4GB 1333 Mhz DDR3.

I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster. I was going to take my computer into an Apple store until I found this thread. I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button. Nothing happens on the screen and the computer did not turn on. I then released all the buttons at once after holding them down for 10 seconds.
After that, I simply turned my computer back on and everything seems to be working fine. The fans are not blasting anymore. I have a newer MacBook Pro where I can't access my batteries. The SMC reset may differ for other types of laptops.

Fan runs loudly and upgrades
