MacBook Pro :: CPU Load And Temperatures?
Jun 6, 2012
My 2009 13" Unibody MBP will overheat if I so much as look at it, or so it seems!. The issue here is that the fan will come on really loudly and the bottom of the machine will become unbearably hot under the following conditions:
1. CPU load = 20%, temp = 76 C, browsing the web
2. CPU load = 33%, temp = 77 C, watching an online video
3. CPU load = 35%, temp = 82 C, watching a movie on lovefilm
3. The lid of the laptop is closed, and I am carrying it in a bag
4. I am charging it with the lid closed.
5. Using an external monitor I have to keep the lid open and on battery use, otherwise it overheats and the fan come on loudly. Obviously if I shut it down there is no fan noise, however it still gets hot when charging.

I'm using iStat Pro and I'm just wondering what "too hot" is as far as temperatures go, specifically CPU, HD? I play CS Source and Warcraft 3 occasionally and it tends to get very hot. Up to about 176 degrees F.

I've recently uninstalled Fan Control and smcFanControl from my Macbook Pro, after trying them for a minute or two. I reset my SMC by using the method on Apples website (Clicking Shift-CTRL-Option-Power Button at the same time). It haven't worked it seem, as I have tried running some games and even at 85-90C degree, its not increasing its RPM. I don't wanna go any higher as I don't wanna risk the CPU overheating.

I have a recently purchased brand new 17" with no upgrades. Do you have a list of what the average temps should be? I tried searching the Apple site and using Google, but no luck.

I have a 2006 blackbook. Recently i feel like it is reaching uncomfortably high temperatures, which says a lot since it always gets hot. i'm using snow leopard but i don't feel like it is due to sl. Here are the temps that istat gives me (in farenheit)

So apparently every time I restart, iStat pops up annoyingly and tells me its now a paid program, and I don't want to pay for it. Are there any alternatives to see my CPU speeds and temperatures, also my memory usage in the top bar? I want something that I can always see.

i have a 2.4 ghz alum macbook and i was wondering at what temperatures does your fans start to actually spin up. i'm at 70C right now and it still hovers at +/- 2000 rpm just wondering if this is normal i used smc fan controller for a little bit but i decided that i would just leave it to apples default and use a laptop cooler if i really need the extra disccipation.

lately my macbook has been getting a bit noisy and hot the fans seem to kick on alot 3500-4500rpm range and @idle my CPU is ranging 68-75C (iStat), right now as im typing this she's at 77-80C. Functionality aside everything is pretty stable, including playing the occasional WoW.
Anyone else have any issues like this? I've booked a Genius Bar appointment just in case.

this is my first iMac, so Ive this questions;
In these days it's very hot here, 32� (90F) and over, and my room is exposed at sunlight all the afternoon, and its not very big.
I hold the window closed, but its always hot in the house, 26� (79F) or more.
If I hold the iMac turn on (with minimum brightness) for 10 or more minutes he starts to be heated, and now for example, that is night and I've 24�(75F) in my room, I've these temperatures:
It's normal?

I bought my first Mac a few weeks ago and so far I'm very happy with my decision to switch from Windows to Apple. But there is one thing that worries me..the temperatures. Here's a screenshot from istat pro. Are these temperatures normal (especially the temperature of the power supply)?

I have an octo 2.8 which I use at 3.2 overclocked, and I have been running handbrake for 20 hours straight, utilizing all 8 cores. So the machine has been working full capacity for 20 hours, and I check CPU temperatures with Hardware Monitor, and they are 55 degrees. These CPU's are ok up to 100 degrees or so. So how can they stay that cool even at full load? I wish I could overclock them even further but RAM's can't be overclocked further so I need to stop at 3.2 Ghz.

I just bought a iMac 27" i5 version with the 2-TB Hitachi HDD.
Under browsing:
Fan-speeds:
ODD: 998 rpm
HDD: Always 1100 or above
CPU: 939
Temperatures:
ODD: 46C
HDD: 57C
CPU: 43C
The only thing what bothering me is the loud HDD fan. Really annoying.
So, what for iMac have you and what are the fan-speeds and temperatures of your iMac? And of-course how did you solve these high fan-speeds? (If you did)

Just wondering if anyone with a new 21.5" iMac would be so kind enough to post the system temps from a app such as iStatpro. I'm interested to see how hot/cool they run.

I just had the original HD on my iMac fail suddenly. Apple was great in getting me a replacement quickly. My question concerns the normal operating temperature for the iMac's CPU before versus after the replacement of the HD.I use smcFanControl just to monitor the CPU temps. During the two years I used the original HD, the CPU temp never exceeded 140F. Within two days of running the replacement HD, the temp has been up to 152F several times.
I have great faith in the engineering that Apple put into the iMac, but on the other hand, I did just have the original HD die on me. Recognizing that this could have happened for a myriad of reasons unconnected to CPU temps, I nevertheless wonder about the correlation between HD health and CPU temp.

I noticed my computer was getting hot to the touch, and warming my computer room significantly.. So I checked my temperatures for the system and noticed everything seemed normal except for the Northbridge Chip (127 C) and Northbridge Heat Sink (62 C). I am running no applications, CPUs are basically idle.
I am concerned that this temp is WAY higher than it should be, using Google, I found that many users were concerned that 80 C was too hot for the northbridge when the 2009 Mac Pros came out. What should my course of action be?
Is there a hardware button to reset everything back to factory without reinstalling Mac OS X?

I have a problem where finder (under any condition even after a fresh restart) does not load the folder contents on my computer. Sometimes it loads after multiple restarts but somtimes it doesn't. I cannot browse through files anymore as nothing appears. Nothing also appears on terminal either. Here is a screenshot.

My MacBook would not load web pages, do I restarted it. Now it will not load anything at all. The screen comes on, but the color wheel spins, then all applications disappear. There is only the background picture and the arrow, nothing else. I already shut it down, removed the battery and then turned it back on, nothing still.

I just received my MBP yesterday. Installed a new HDD right from the get go.
Though, I read something disturbing about load cycles of an HDD which is not native to a MBP. Apparently the load cycles can get really high which decreases the lifespan of an HDD.
Now, obviously I don't want that to happen and took a look at my load cycles. The MBP has been on for about 3-4 hours now and the load cycle is at 224.

I have a dvd-r that has a bunch of IVR video files and some text files that I use for school. For some reason when I put this dvd into the macbook It prompted me as if I had inserted a blank cd. I knew it wasn't blank because I have used it on my old windows laptop. Knowing this, I put the disk into my windows laptop, ran it, and pulled up the content. Then I tranfered all the files from the disk to a external hard drive and pluged that into my mbp. The Mac could now see all the files including the IVR fomated files(??) but did not know which program to open the IVR files with. So I drug the IVR files in to my VLC player and it reconised them but showed them as being 00:00 long and played no content. This was confusing because VLC usually could play these files. To be sure that it wasn't just VLC, I downloaded Real Player ( IVR native player) and tried playing them in that but got the same 00:00 play length and no playback. What I want to know is why didn't my mbp reconise the dvd-r and are IVR files just not compatible with OSX or is there somthing else I could should do?
