Mac running hot

Hi all, I have a new Macbook Pro 13 inch and I replaced the HD and memory from the base model to a 320gb 7k drive and 4gb ram.
Everything is fine and fast, all memory is good, but I find the CPU temperature is up quite a bit.
The mac is running at 126degrees normally and goes upto 170 when doing surprisingly non intensive tasks.
Is this about normal or should I expect to see it at around 100?

Faster drive do generate more heat but a new 7200 RPM (assuming that is what the OP means) may generate even less heat than an older 5400 RPM. I have verified this in two installations I have done.
My house runs around 75F and my 15" MBP runs around 98F to a max of 111F when surfing the web via its WiFi. The only way I can approach 176F is if I am doing a very CPU intensive task such as compressing video and other simultaneous tasks.
An increase of 20F caused by a new drive and RAM tells me something is amiss. It may be that your drive is very poorly speced but I would swap back the old drive and double check. Maybe your new RAM is defective in some manner.
One reason the MBP gets such amazing battery life is that it uses very little electrical energy, and this means it produces very little heat. All the heat in a computer comes directly or indirectly from the electrical power source including the air friction heat generated by the spinning HD.

Mac running hot and loud ... even when sleeping : /

Hello,
My 2.8 GHz Intel Core i7, Mac OS X (10.7.3), 8 GB Memory has become a
'earsore' ... a few months ago the fan started coming on more and more often and became progressively louder. The only way I could get the fan to power down was to put the machine to sleep or power off.
Now, putting the machine to sleep doesn't turn the fan off until minutes later, and now I notice when I put the machine to sleep overnight it is still warm in the morning.
What's most perplexing is that I have AppleCare and had a technician come out to my office a few weeks ago and replace one of the fans and cleaned out the intake panel at the bottom of the monitor.
The problem went away for a day but then came right back.
I'm going to contact Apple again, but wanted to find out if anyone has any insights beforehand.
Thanks.
Ramone

Have you tried resetting the SMC? Please follow the directions below closely, if it doesn't work the first time do it a second time. If that still doesn't handle the issue then contact AppleCare (I'm assuming the machine is covered by AppleCare) so they can begin troubleshooting it.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Why is my mac-pro ci7 running hot while working with imovie and eyetv?

Hello,
I am creating short videos of ps-3 gameplays. For recording I use eye-tv and my mac is connected through a HD-Haupauge with my Playstation. When transferring the recording-file from eye-tv to i-movie and getting started to work on the video, my mac runs hot. I have to underpin the mac, so that there is enough space for cooling, which doesn't help that much.
What could be the reason? I bought themac last year in summer. I am not sure about my operation systems number.
Thanks for any reply and good advice i hope to get.
Kind regards

2008 Mac Pro 3,1 RAM burning up - running hot

Problem: 2008 Mac Pro Tower running hot.
Possible causes: Power Supply? Fan not working? Machine has 667 mhz RAM not 800 mhz.
PSU was chirping like a cricket a few weeks ago. I pulled it out, air cleaned it (and the entire Mac, vacuumed all the dust) and left PSU out for 12 hours to static discharge, etc. When I put the PSU back in, it was working and the chirping was gone.
Successfully used the MAC for a few days, no probs other than 2 DIMMS went bad. I went away for 2 weeks, tried to start-up the Mac yesterday and it wouldn't power on at all, no light. I unplugged it, tried different outlets, power cords, etc. Then I removed any changes that I had made previously (i.e. installed diff HD and 2 new RAM DIMMs to replace the ones that burned up) before going away. I removed PSU and let it sit while I cleaned the 2 DIMMs that had seemed to overheat before I went away. Put it all back together (PSU, old DIMMs which were cleaned and left HD #3 out) and it powered up. I then noticed that I was down from 32 GB RAM to 16 GB very quickly. The machine had also "shut down because of a problem" during that time then restarted and ran for a bit. I repaired the 16 GB RAM by cleaning it, brought it back up to 32 GB again and within minutes it was back to 24 GB. I pulled the RAM cards out and they were hot. The last 8 GB to go were likely the only DIMMs I haven't cleaned yet. I don't know how long that fix will last. Seems like we have a pattern of over heating.
Any ideas? Is it the 667 mhz RAM? The PSU? The fan? (How do you test a fan?)
Thank you for your time.

First the RAM must be made for your computer as determined by Apple:
https://discussions.apple.com/docs/DOC-6413
Thus you have an early 2008 Mac Pro if it is a Mac Pro tower and not a MacBook Pro notebook.
The RAM must be either preinstalled by Apple, or from a place that sells lifetime warranty early 2008 Mac Pro RAM.
Just because you got PC6400 DDR2 ECC 800 Mhz FB-DIMM with 256 bit wide memory architecture, as the specs call for,
does not mean the RAM is compatible. Only RAM stated to be for "early 2008 Mac Pro" is compatible with those towers.
http://www.macsales.com/ (OWC) http://www.datamem.com/ and http://www.crucial.com/ all sell RAM by stating the time of year and model name.
Do not buy ValueRAM. If after doing that it doesn't work, some directions for other interior repairs exist on http://www.ifixit.com/ and http://www.xlr8yourmac.com/
Check to make sure the circuit your machine is on is giving off the full amp called for by specs and that current is not split to other devices, and you have either a UPC or surge protector power cord that can handle that ampere. If there is any chance the machine was plugged in during a lightning storm, your power supply may be fried even with a surge protector or UPC being there. No surge protector is 100% lightning foolproof.

My Mac Book Pro is running hot AGAIN

Hi All, recently i rang Apple Support as i have Apple Care and a very helpfull man led me through TWO different procedures to solve my problem of my Mac Book pro running very hot in the area underneath at the rear.
both procedures involved me switching it On and/or Re-Booting and pressing three and/or four different keys on the keyboard !.
Whatever it did certainly did work..
However it is now running hot again and i have been trying to find on the Apple Support site, what i need to do to do this process again !
I was hoping to avoid phoning the Apple Care number again when i dont really need to, but I CANNOT find the support articles i need.
Can anybody help please
Tim

That is what i cannot understand, SANJAMPET says do this reset stuff when shutting down, while the apple folk say do it while switching ON ????
Why two diferent methods ?

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.

Mid 2013 macbook air: battery drain / running hot

Hi there,
For the last couple weeks my MBA starts to run hot and drain battery fast if I've been using it for a few hours.
I use it a lot on most days and connect to powercord only once it drops down low, like below 20%.
Have just seen other posts who recommend doing that at 50% battery and will now do the same.
However my question is: have i ruined my battery in the meantime?
AND/OR is there something else i can do to get battery running like it used to, and stop the loud fan switching on all the time because it's all running too hot?
I've copied in an etrecheck in case that helps diagnose more....
thanks heaps for any help!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator.

7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.

Windows Vista 64bit on boot camp running hot?

I have just installed win vista and seems to be running quite hot?
I hardly use Microsoft OS anyway its just for apps but that seems to be running hot and not comfortable with it.
any idea?

Mainly this is because Windows cannot control the fans which causes the computer to heat up. It's a well known problem.
Some solutions include the use of fan control software for the Mac such as SMCFanControl to set the fan's idle speed to a higher level before booting into Windows. Another solution is Input Remapper.

Imac 27 runs hot as ****, won't sleep, and cpu runs wild in w7

I have been having audio issues with the imac 27. plugging headphones or speakers causes cpu to run crazy, the mic in the triband trrs jack does not work, and the imac runs hot, and will not go into power saver mode.
When I came in I found my nephew who was listening to some music on the imac, and I felt the back top of the imac and it was hot as ****. I almost burned my hand. I realized then that he had plugged his headphones in.
Unplugging the headphones or speakers can solve some of these problems.
But, this is not an acceptable fix.
Please contact Apple and urge them to fix these sound card issues.
If anyone does not have these problems in w7 with the imac 27 even after the latest bootcamp and imac updates, let us know right here. I think this affects every one of the late 2009 imacs and maybe some earlier ones too running windows 7.
Here's the post I recently ran on the headphone jack issue.
Not only does the cpu run crazy but the imac 27 gets very, very hot. Since I unplugged the headphones, it runs much, much cooler.
Certainly, some Mac engineers should take care of this problem, it seems it is universal on all the imac 27's and from what I gather, the smaller screened cousins too.
Also, we certainly want a stereo mix option for audio in or out, or what is called "what you hear" or wave out. Imac is supposed to be much geared to multimedia apps.
Finally, the mic jack part of the trrs set up MUST be fixed! A lot of manufacturers are going to headset combo jacks as they call them, mic in and stereo out on the same tribanded plug. But, the old single jack for mic in and single jack for stereo out are two tiny parts of the hardware and super inexpensive for the manufacturer. Why in the **** to go to the "advanced" triplug if the **** thing doesn't work.
Mac has a great reputation. I hope they remedy these problems right away.
Anyone whose imac 27 or 24 whose headset plug is working correctly. Let us know! I don't think anyone's is, but I think that few people understand that their cpu is running so much faster with the plug in, plus few even understand the combo jack and the triband, or trrs audio jack! Out of 4 audio technicians I talked to, not one of them knew what a trrs jack was or that you even have a mic in jack as part of the headset jack!
When I told one senior that it worked on the Mac side, he didn't believe for a while, thought my sound might be recorded from the onboard mic, but I proved it to him by tapping iaudibly on my iphone mic headset and and it showing up in garage band clearly and listening to big difference in audio.
As for a usb audio adapter, I am in a neon light environment and find that those adapters are more sensitive to electrical interference. Besides I want to use the headset jack as it was meant to be used!
Thats it.
Again, if anyone using an imac 27 and windows 7 64 or 32 doesnt have these problems, let us know! We are all anxious for a fix!
Best to all!

Yes, I have been dealing with this problem since early January. I just can't believe that apple would not have the necessary driver for the sound card in the Imac 27! That's like trying to run a race and not bothering to tie your shoes! How can they not have something as basic as the sound connections working???
I was encouraged to buy a top of the line imac 27 because Apple had told us that bootcamp would enable Windows users to use the machine just as if it were a native windows machine, then they don't give us the **** drivers to use the trrs mic jack. And you can't use the external speakers without the cpu going wild and heating up like a pot bellied stove.
This is really disheartening and now I am really thinking I made a big mistake. I wouldn't mind migrating to Mac gradually, but I have lot of scientific and other programs that require windows. At this rate there will be thousands of other mac buyers who will never make the same mistake again.
As you can see I am quite angry about this, and getting more angry with each day Apple ignores every imac purchaser who expected to use Windows on the machine! Is the software for a sound card driver that difficult?
Having a computer which doesn't have sound that works correctly, is like having a car without seat, you can still drive it but isn't very **** comfortable.

MBP running hot, full fans and sluggish with both Safari and Firefox

Hi guya,
Im having problems with my kate 2007 MBP.
Im sure lately it seems to be running slower and slower and more and more sluggish - I was hoping my Mac wouldn't be subject to "slowdown" like every PC ive ever owned has.
The biggest problem is that if i use either Safari or Firefox to browse the web, they quickly start using 80-100% of my processor causing everything else to run sluggish, the computer to get hot, processors to run up to 90 degrees and fans on full.
Perhaps i multitask more than some people - I can tend ot have a lot of tabs open in Firefox, but sometimes Safari or Firefox show this behaviour with just one tab open.
I do multitask by having about 8 programs open at once and I jump from job to job, but in its early life the MBP used to deal with this - now i feel that i type faster than writing appears on screen, i have to wait ages to work in programs like indesign, and forget trying to run a game like The Sims...
Does everyone else have the 100% processor problems with Safari (and yes im on version 4, and the latest version of firefox too) the only browser which doesn't give me these problems is Opera - I can have many tabs open and it uses very little CPU, I just dont like use Opera as much as Firefox which is my browser of choice.
But why would my OSX run differently to anyone elses? Is there a problem with my Macbook, is there a problem with OSX (does it need installing again?) Is it just time for me to buy a new Macbook Pro - or if I run firefox on that will i get the same problem? Ive got nearly 30gb of spare HD space and maxed it out with 4gb of Ram - so neither of those are causing a problem either...
Any input would be great...

Have you tried restarting the comp? Sometimes a simple refresh will cure the sluggishness.
Try running repair permissions from your HD and afterwards run +repair disk+ from your software install DVD.
Regarding your comp running hot, make sure it is properly ventilated while in use. The MBP is not a laptop. According to the user manual it states in part:
+"Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings."+

Dead USB port running hot

I have a mid-2010 white unibody MacBook. It's been running fine, with the exception of a problem with the dashboard after the most recent firmware upgrade about a year ago. I just learned to work around it. But then Friday I got an error saying the the USB port was drawing too much power and was shut down. Sudden and random, as it had never happened before and showed up as I woke it up from screensaver mode. Nothing was plugged in. I have a Magic Trackpad and a Logitech keyboard connected via Bluetooth. Disconnecting them doesn't affect the error. I've tried rebooting and resetting PRAM & SMC. I'm trying to reinstall Lion, but I don't think it's a clean or fresh install. Has anyone encountered a USB port that dies but runs hot? The CPU seems to run a lot warmer than usual, buy about 20° F.
Any help is appreciated!

Take a look at this discussion:
https://discussions.apple.com/message/22922870#22922870
I recommend you make an appointment at an Apple genius bar and take the Mac in for a free diagnosis.

My PowerBook G4 runs hot after installing iTunes 7.1

Only Safari and iTunes open. The iStat Pro shows the CPU bottom and top around 55 degree Celcius (but the temp haven't changed since then...crash between 7.1 and iStat? but I can feel my PB runs hot)
Anybody got the same problem?

Ditto here.
Mac OS 10.4.9. iTunes 7.1.1 (5)
Airport Extreme Base Station "chained" to 2 Aiport Express Remotes. All connections are fine. Have internet on remote Macs. Airport Admin utility displays all three airport units, but I'm now unable to broadcast to the remote Express hooked up to my stereo in adjacent room. Have done this many times in the past without problem, but not in past couple months, so can't say if it broke with 7.1 or 7.1.1, but I get this message from iTunes:
The remote speaker "Living Room Speakers" is not compatible with this version of iTunes.
Prior to restarting iTunes (and being sure all Aiport station firmware was up-to-date, I was getting the message that no speakers were connected (double-checked all speaker and stereo connections), but now just the "not compatible" message.
