Hot Hot Hot. My Powerbook is hot and the fan never turns on!

Hi,
I downloaded the istat pro widget in order to monitor the heat and fan on my Mac. Currently the CPU top is 141 F and the CPU bottom is 140 F. The front and rear fan are not on and it seems like they should be.
When are the fans set to turn on... can I change this?
Are my fans not working.
Give me your insight. Thanks!

Look here:
Apple Specifications
http://support.apple.com/specs/powerbook/PowerBookG4_15-inch_1_67-15GHz.html
Electrical and environmental requirements
Meets ENERGY STAR requirements
Line voltage: 100V to 240V AC
Frequency: 50 to 60Hz
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -13° to 113° F (-25° to 45° C)
My computer temperatures are constantly on the upper end of the scale, as well as frequently going over the operating specs listed by apple. I believe these are environmental conditions for operation, but currently my cpu temps are 120/114 according to istat, so this should give us some ammo for repairs, a recall, or something, as the obvious internal temperature is not within Apple's operational specs. Even my powersupply is 109f currently...
This has got to be wrong... Lets fix it apple!

My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

My mid-2012 MacBook Pro has the fan constantly running. As soon as I turn it on. My MBP won't even be hot and the fan is running. How can I fix this?

If you are still under warranty and/or have AppleCare, call them. Let them deal w/it.
OOW try the following: http://support.apple.com/kb/HT1411 Apple Portables: Resetting the System Management Controller (SMC)

When I'm streaming videos from my Macbook Air to my AppleTV, my Macbook Air gets rather hot and the fan works hard and is loud trying to keep the laptop cool. Is this harmful to the laptop? Is this normal?

My MBA fans start running when I play video too - the CPU's video processor is working pretty hard to decode the video. The fans job is to provide better airflow. The time to worry is when you play video and the fans don't run.

Late Macbook Pro getting hot and the fan is getting louder

My Macbook is getting very hot and the fan gets louder the longer I have my Macbook on.
It happens whenever and wherever I use it, I don't play games often as I use my Macbook for my Uni work.
Does anyone have any advice?

It would help if you indicated the EXACT model MBP that you have.
Perform a SMC reset:

If no success, open Activity Monitor to ALL PROCESSES and set %CPU to display values from high to low.
Download from the Internet a temperature monitoring app like Bresink:
http://www.bresink.com/osx/TemperatureMonitor.html
Post images of both for inspection.
Open the MBP and look for dust an debris inside it, especially in the fans. Clean it out if necessary.
Ciao.

Is it normal for the mac book air to run hot and the fan to be loud

I just bought my daughter a mac book air a couple of months ago and it is now running hot within two minutes of turning on and not doing anything. then the fan is loud running hard to cool it down. it does not stop. left it alone for 20 minutes. still hot and the fan is loud

It's not normal. Read Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
Power or other problems related to unexpected system sleep, shutdown, lights or fans also call for an SMC reset.
Read and follow the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

My macbook is extremely hot and the fan is worryingly loud, what is wrong with it and how do i stop this from happening?

For soem reason if I actually dare to use my macbook the fan kicks in and is so loud that I am unable to use skype or other voice programs without a headset because of its volume, also it gets very hot very fast, so hot that if I rest it on my knees it burns. I normally have it on a desk and the area is well ventialted. I have no print queues and rarely have more than two programs running at a time. Can anyone offer a suggestion of what is wrong and how I can fix this please? One of the main reasons I bought one in the first place was that they are so quiet when shown them in the apple store, but this is worryingly loud...

Thanks, it seems that it doesn't like to play games, which is a bit of a bummer as i bought this specifically because it was capable of doing that. To be fair, it is capable... I just need to get used to a sound like sitting by a washing machine on spin cycle... Wish they would make people aware of this in the Apple Store, its very misleading and not at all desireable.

My Mac Pro Lion 10.7.4 is getting hot, and the fan is making some noise.

Since I've got this Macbook Pro Lion 10.7.4 (October, 2011) the temperature of the backside is very hot, and today (July, 2012) the fan is making some weird noise. Does anyone know what is going on?

My MacAir purchased Sept 2011 gets exceptionally hot after charging for 10 minutes when the fan comes on. This also happens if I'm listening to music or watching something on YouTube after a few minutes. The machine gets hot and the fan comes on.

My Mac Air purchased in Sept 2011 gets exceptionally hot after only 10 minutes of charging with the fan coming on. This also happens if I'm listening to music, watching a video, or doing an online crossword puzzle. When I shut it down the fan continues for a few minutes before shutting down. I took it in to the Genius Bar and they claimed the heat was within specifications.. I've owned several Macs and Mac iBooks in the past and this has never happened before.. Has anyone else had this same problem or have heard of it?

Hi...
It should not get that hot under 'normal' use.
First try a SMC reset.
Also note that it's a known issue that when attaching the magsafe connector and then within a few seconds opening the lid or in reverse, it can heat up for no aparent reason. Closing and reopening the lid should solve that.
A workaround for this is to wait ca. 15-30 sec. after opening the lid, before connecting the magsafe.

My computer has been freezing and then emitting a consistent beeping until I shut off the power. It has been getting really hot and the fan gets really loud. This has been going on for months. What's going on?

I just had my macbook pro checked out and all of it's systems restarted to solve its beeping and freezing problem. However, it is still shutting itself down when I close the lid and becoming very hot. When I open the lid again the screen is black and I have to continually hold down the power button in order to turn it back on. Does anyone know why this is happening?

My laptop is getting very hot and the fan seems to always be on. The battery dies quickly too.

Mac Pro 4 + years old. Bottom getting hot. Fan seems to run constantly when in use, or when charging. The charge does not last longer than 2 to 2.5 hours. Unplugging seems to cool it off as well as shutting down.

Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Just updated to 10.7.2 and the fan on my 2011 mba wont stop running.

I updated my 2011 Macbook Air to 10.7.2, and now the machine is really hot and the fan won't stop running. Any idea how I can make this stop?

There is likely a program or process that is taking up most of the CPU. If you open Activity Monitor and sort by the % CPU column that will tell you which process it is. If its a program that don't need then you can simple quit it. If its something you don't recognize or something that you need to have running then report back and then the next course of action can be figured out.
I had this problem with the Dock. Deleting the dock preference file then restarting the Dock process addressed it. Your situation may be different.

This is a weird start to my question; but i went to a music festival today and I was in a mosh pit and it was hot, and my iPhone 4 turned off and I was wondering weather it was from the heat or something else? And what I could do to fix it? Thankyou :)

My Iphone 6+ gets very hot and the screen pops up a little

My Iphone 6+ gets very hot and the screen pops up a little. Is that normal any one experience this before?

I did yesterday. They inspect and repaired it. And gave me back my phone and claim that its was not assembled well at start. was an un aglinment. They have fixed it and aglined it according to them. I dont feel that that could be the reason. I have used it for half a yr already now then its un aglinment appears?
