OS X :: Won't Work With Temp / Overheated And Shutdown
Mar 20, 2010
Alright I am wondering what temperature the computer has too get too in order to shut itself off. what I mean is, at what point will the compute shutdown or crash before it overheats? I think my mac mini (07 model) is getting too hot and it shut off a few mins ago (not gracefully shut down more like someone yanked the powercord out ) and I think that the shutdown may be related to heat problems.
idle temps: (celsius)
ambient:54
CPU:72
CPU heatsink:60

Fan RPM:5100rpm

I did nearly six hours intense work on my MacBook Pro yesterday (Photoshop, Indesign, updating software and numerous other tasks).
I don't have a temperature gauge in my menu bar, so I don't know how hot the MacBook became, except it was quite hot to touch at the back.
Can this happen?

So...basically what is going on is that after a while, depends on how hard my computer wants to run and make itself hot, it will completely shut down. . .not sleep, power off.

I downloaded a program to monitor my late 2008 unibody Macbook Pro's temperatures. Just a few minutes ago while playing music/playing an ONLINE game real briefly it warned me that my CPU temperature was too high. (167˚ F) Is that too high of a temperature? What should the "range" be?

I was just adding some Quicklook plugins when my temps started to soar. I have restarted, repaired permissions, removed said plugins, and tried other accounts. Nothing is lowering the temps. Weird thing is is Activity Monitor is showing NOTHING using the processor nearly enough to jump my temps to 85 C with nothing running.
I'm "controlling" the issue for now by ramping my fans to full speed. Even with this I am hovering around 70 C...a good 10-15 C above what I am normally at (and was at 30 minutes ago).
*Note: Normally running fans at 6000rpm would give me temps in the mid to low 40 C range

I have a MacBookPro5,4 2.53GHz with one fan and only the 9400M. After updating to 10.6.3 the operating temperature seems to have risen from about 43 degrees C to about 48. It has been getting warmer here in Japan so the ambient temperature is different but I still think this rise in temp. is due to the update. I have smcfancontrol installed and set to 2500rpm instead of the normal 2000, but it seems to be not enough to keep the temp. under control, as it did before the update. Any relatively hard use of the cpu and the temp goes up to 60 degrees.

Just had to replace the logic board on my PMG4 DP 1.25GHz machine. For the life of me, I can't remember the operating temperature before I swapped the board. Currently it's running at 130F - 140F. This seem about right for the other folks running these machines?

I've just been watching something on BBC Iplayer (using opera) and the CPU temp is up to 65 (with ambient temp 33). Is this normal? (finished watching and it's now at 60.) Also, the last few days I noticed the mouse button not working properly, sometimes I need to click twice for it to actually work, and if I was holding down the left button to drag, it kinda lost it's connection (so while dragging and moving things around the desktop they'd stop while the cursor still moved as I was still moving the mouse... and the mouse button was still pressed in all that time). I'm thinking it could be to do with temps as it has been really hot here lately (but then shouldn't the fans kick in?).
I've done an archive and install but it was still the same last night (mouse 'click' seems to be working ok right now). I 'think' the temps have been going up to 69, but I didn't make a note for sure. Should I do a clean wipe and install in case one of the programs is conflicting or something?

I just started using the aluminum MBP 15" and used to have 13 Macbook aluminum. and as far as i can tell the 13" did not get as hot as my 15" I just installed a fan and temp controller and even with running the fan higher then default os 10.6 temps reached 165 F I freaked out and cranked up the fan to 5000 RPM and temps dropped so far. So, How hot are these MBP supposed to get until it no longer safe?? And its not even close to being where the MBP is: sitting in my office on a desk where its cold and i have to drink tea to stay warm.

im running at cpu temp of 82C with my fan running around 2000 rpm with the mbp in my sig. Is this a normal temp to fan rpm ratio? Why is bothers me is that im use to my Mb flaring up its fans every time it got hot.

Does the macbook run cooler with an SSD instead of a traditional hdd? My 13" is running quite hot so I'm looking at ways to reduce the heat.

So I just installed the new 200GB OWC Mercury Extreme SSD (SandForce Chip) in my 2008 Penryn (non-Uni) MacBook-Pro.
Seems pretty fast and all, but iStat is displaying a temperature of 263 degrees?#!#$%@@#
I know this thing can't be operating at 263 degrees, though I placed the temp monitor at the exact same location it resided on my prior 5400 RPM hard drive. Not sure what the problem could be.

It just froze on me about 20 min ago. All I was doing was listening to iTunes and browsing the music store. I looked at the temp of the computer and it seems kinda high, I don't know too much about this.

I've notices a really strange behaviour with my 13" MBP. The fan simply doesn't go faster on high loads, which results in a CPU temperature that is far beyond the operation specification Intel provides.
Seems as if the SMC controller is kind of broken. I tried to reset it, but that didn't change anything. A PRAM reset also didn't work.

I'm nervous to install the Firmware update 1.3. As I've heard from a lot of people the update has crashed their mac. I know it has to do with the fans and temp. My Mac book pro is running at 135 F at 2000rpm is this ok? Is it too overheated. Should I install the firmware I'm so nervous to install it just in case it breaks. Here's the rest of my specs...
Model Name:MacBook Pro
Model Identifier:MacBookPro3,1
Processor Name:Intel Core 2 Duo
Processor Speed:2.2 GHz
Number Of Processors:1
Total Number Of Cores:2

I just got a new macbook pro unibody a few weeks ago, and when i go to shutdown the mac, my cursor is stuck for a good 20 or so seconds and then i can finally move it to shut it down. This does not seem normal to me and am wondering if this is an isolated event or it happens to others? Is there a fix for it? Such as a new driver, reinstall, etc.

several months ago when my ibook g4 was just over a year old it began suddenly going to a blank screen when the battery was fully charged and the computer was unplugged. Sometimes i would hold down the power button and the computer would come back from seemingly having fallen asleep. other times i would have to plug the computer in and hold down the power button for it to come back. to do this it would make this whirring fan sound before going from a black to a gray screen and then finally re-starting up from the beginning. a box would then appear telling me that my date and time were set wrong and that this could cause some functions to behave erratically. this despite my having frequently changed the date and time zone back to my own and locking the settings. the computer keeps switching the date back to 1969. and now when i put a dvd into the computer it just spits it back out and won't play it. long story short...i am beginning to hate my mac. what's the point of a laptop if you have to leave it plugged in for it to work. apple tech support has done nothing to help me and has refused to admit that the g4's have a problem despite my having read about tons of people having these exact same problems after a year. i read something about how in denmark this consumer group proved that there was a faulty part attached to the battery coming loose and that they were suing apple.

I've been hearing a lot about macbooks overheating, and was just wondering what are the ramifications of it overheating? Does it act slower, or over time does over heating lead to long term defects or something? Are there sings I should look for or something I should do if I sense my mac getting really hot?

Earlier this evening my Pro (OS X Lion) overheated seemingly randomly. I gave it time to cool down but had to restart it. Not too long after restarting, it started blaring a klaxonlike horn at me. I didn't know what to do so I just shut it down. It's working better for now, but we'll see.

Don't know what to do. Do not have apple care, mac was bought through school and is 4 years old. Is there anything that can be done to save it?

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
