MacBook :: CPU Runs At High Temp - Wants To Reduce The Heat?
Mar 10, 2009
I'm using iStat and it says that my CPU runs at temps around high 70s, low 80 degrees Celsius for about 10-15 minutes at a time (also says the same for Airport card). It usually takes a while for it to cool down. I always place my laptop on flat surfaces. It does this even during light internet surfing minus flash or any other multimedia...now WITH multimedia use, it reaches the 80s no problem and I just quit the process cuz I don't want my laptop to explode one day.
I just wanted to know if this was average and what temps everyone else is usually running at?
I'm afraid that if it runs at these high of temps for a long time each time like that, then it may do some damage somewhere...
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 wondering if there are any ways to lower system temperature on MBP? My machine would get hot (particular the left side) even though I am just doing simple tasks like surfing and word processing.
What is your heat sink temp when the cpu is running hot, like 90+ degree C?
I recently performed the excess thermal compound removal procedure. Now I am worried that my cpu and heat sink are not in 100% contact, due to the very small amount of paste applied.
My heat sink sits at around 50C under normal load (cpu temp ~ 60). But at high load, cpu up at 90+ C, my heat sink is still at around 50-60C. Is this normal?
I don't see anyone else mentioning temps this high. My specs are below. I followed the directions in a post here in the forums and his directions did work, and I used the modified latest drivers from laptoptogo (258.96), and I was able to overclock the gpu on the windows side. I'm using Vista 32-bit (I know, but that's the only Windows OS I have). I didn't even OC it much, just 550 on the core and 1200 memory, and all was well. The framerate noticeably improved and I was able to play SC2 on mostly high settings (including shaders) with FPS ~ mid 30s and lowest mid 20s. I was a happy camper until I checked my temp via the Nvidia monitor, and noticed it went up to 92C at one point! At first, I thought this was because I was playing on 1080p on my HDTV, but I played again and it went to 88C on native screen.
A couple notes: I did not modify fan speed (allowing the native algorithm to run). I have a Core i5 15-inch MBP, 2.4GHz, high-res matte screen, 320 GB HDD, Vista 32-bit under bootcamp. Playing in native res. How come my temps are running so high? I know YMMV but I haven't even OC'ed it half of what people on this forum are doing successfully with stable temps in the 70s. Also, could it possibly be the fact that I'm using the latest drivers and maybe I need to use the older driver people are mentioning on this site? Is it possible I need to monitor my temps with another program other than the Nvidia one?
I had my computer idling and noticed that the fans sped up to full blast, so naturally I tried to figure out what was causing it to heat up. I quit pretty much every app I had running, no diff. I unplugged my iPhone, no diff. Even shutdown the computer, fans went right back up as soon as I loaded up OS X. So I looked at SMC Fancontrol (which I never really even use) and the temp was at 88 C!!
I have nothing open, completely turned off the computer and rebooted it to make sure that nothing running would be causing it, and it's STILL running hot as hell! Is there anything I can do to see what's causing it to run so damn hot? I really don't wanna put a crap-load of wear on my fans and CPU here.
I'm using a 2.2 ghz SantaRosa MBP running the latest version of Snow Leopard.
Today I tried to "empty the trash securely". There were 73 items. After 5-8 minutes I selected "stop" because the Fan was at 5400 and the Temp was 78 degree C. This is the first time I have heard the Fan. Also, it seemed as though it was stuck trying to empty. That is when I noticed the temp/fan issue.
MacBook Pro 2.16 Intel Core2Duo with 2 GB 667MHz SDRAM runs very quietly when being used. When left with lid closed overnight but still logged in, each AM the the fan is running loudly at high speed and the case is hot. As soon as I open it and it starts up, the fan quiets down and the case is cool in a few minutes. The temps range (when open and quiet) from 90-125 F for various components and the fan speeds are about 2000 RPM. Why should it run hot when closed and asleep.
Macbook Air won't shut down and often the fan runs at a very high rate without stopping. I do notice it seems to get hot on the bottom more than in the past. Any suggestions as to what I should do, I can't keep holding the power button down to shut off the computer.
I only started noticing my fan running a bit on the fast side this evening after installing the new Safari 4.0.5 update. I looked at iStat Menus for temp and CPU. And I was seeing about 190 degrees F for CPU temp with lid closed running ext display. Also there was a constant usage of the cpu (about 30% User and 20% System). There's not one particular process I can see in Activity Monitor that acting out of the ordinary and using a lot of CPU. Just stuff like coreservicesd, WindowServer, launchd that are shuffling around and using about 1-4% of CPU.I ran repair disk permissions and verify disk. Verify Disk found errors and said I need to repair my Macintosh HD, which I have now done successfully.
Macbook Air isn't a year old and I don't leave it plugged in ever. The battery might last 2 hours and gets very hot. In addition the fan runs at a very high speed. The computer won't shut down in a normal way. I have to hold the power button down to shut it off.
I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.
Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.
My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.
I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.
The fan runs so loud and so high it sounds like it's an airplane that's about to take off.
Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.
I purchased my PowerMac G5 in 2003 and no problems till now. My problem is that on startup, the display first shows gray screen with a globe in a white box flashing in the center of the screen. This continues for about 90 seconds --- then the globe in box icon changes to a small file folder icon with alternating face/question mark flashing in the file folder. At about the same time, the fan speeds up dramatically. The fan continues to run at this high speed for about 90 additional seconds, then the fan returns to normal speed, and the startup continues normally to the blue screen. Once startup is complete, computer runs okay. The whole process takes about 4 minutes.

I purchased a used ibook from owc in January and have had it back to them twice for repairs. Lately, it stopped booting up again and they told me to use [URL] to take the mobo out and ship it to Arizona to have the solder refloated. I did and got it back, put it together and it would boot up, only to run for 15 minutes and shut down. Thinking I missed something, I dissasembled it today and reassembled it. Now it turns on with a blank screen, the fan runs on high, and it will go no further. I tried to reset the power manager, reset the p-ram, the hard drive is only a few months old and my brain is getting fried with frustration.
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.
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
Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)
How does the Antiglare screen look? Does it look cheap and flimsy like the matte screens on the pc laptops?This is my first Mac and i'm looking at going all out and getting the top of the line 15". I know I definitely want the HD screen, i'm just not sure which screen looks better. What about a 5400 vs 7200 rpm hdd? Is this upgrade worth it?
I went to Apple store yesterday. I want a new MBA badly. Only problem is the memory of current model is 2G only not expandable. The guy in the shop has no idea when new MBA will be released.
I was looking at new 13" or 15" Macbook Pro, I like it, and wonder since I don't use DVD that much, is it possible to take the drive out and reduce weight a lot?
I have an Mid-2009 13 Inch Macbook pro. I decided to upgrade my memory to 4 gigs using thirdparty memory. However, I have noticed that the amount of Wired memory usage has gone up a quite bit. My Wired memory usuage usually goes as much as 900 mbs and this is outrageous because I don't particularly open any major applications. My Kernel Task right now sits at 397 MBs, which is huge as well.
I find that with one firefox or chrome browser open, I can easily use over 90% of my 4 gig ram and that's when watching you tube becomes very difficult 9freezes a lot.I understand that I never had this problem with Windows, or even when I run bootcamp.
Here is a print out of my processes:
Active Memory: 1.91 GB Free Memory: 1.02 GB Wired Memory: 853.4 MB Used Memory: 2.98 GB

I am having trouble getting a mail pdf attachment to be accepted by my server. I am looking for a way to reduce the digital size of the pdf (report) so that it will be a size acceptable to my server (tds). How can that be done? What steps should I take?
Info: MacBook, iOS 5.1.1, also have a new desktop MAC
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.
Been having this clicking sound on my 13"MBP lately. I was told it might be the motion sensor being too sensitive. Anybody know how to reduce this sensitivity?
i was playing with my MacBook Pro earlier today and used some kind of finger swipe that made everything on my screen including the homepage zoomed in and off center. I have to scroll from side to side and up and down to see the whole screen and he or I can't figure out how to change it back.
I scanned some documents with my printer/scanner and don't want to have to rescan every time. I made them too big, they are 20+ megs, and I know with JPEGs one can just "flatten" the file. Can that be done with scanned docs too? If so, how? Do I need a special app for that? I have Preview and iPhoto, plus the MS Office package for the Mac.
