Extremely High Temperatures

I have a new 2011 Macbook Pro 17".
With the i7-2760QM processor.
Anyway my CPU idle temp sits at around 65C, to me this is crazy. No idea why it should be this high.
In addition while gaming I am seeing temps as high as 100C.
What can I do to decrease this???
P.S.
Running bootcamp

It would appear that it's not really "idle". My MBA when it is not doing anything out of the ordinary indicates a CPU temperature of 35°.
65° is not normal but it is far from "extremely high".
Gaming, Flash video, any processor-intensive activity is going to make it warm in a hurry, but playing HTML5 video in YouTube typically brings mine no higher than 45° or so.
It is possible an SMC reset might fix the problem, also read the following to identify a particular process that may be taxing your Air's resources:
Runaway applications can shorten battery runtime
Edit: I don't know why you posted this in the MacBook Air forum, I was about to verify the temps on my MBP but Mrs. Galt is busy with it

Satellite P300D-10V - Turn off by high temperature

Hi!
I have a TOSHIBA Satellite P300D-10V and I have a problem with overheating! When I load my CPU with 2,2 GHz for a long time, it turn off by high temperature!
What must be my solution about this problem?
"Normal" temperature for my laptop is around 70 - 75 degrees cslsius! Is it normal for this CPU?
I have used another laptop with Intel CPU and there is no such problem! My Toshiba is in use for 2 years! OS Windows Vista Home Premium 32bit
REGARDS!

Hi alexander79,
First of all you should know that cleaning the fan is not covered by warranty!!! Of course you can do this from an authorized service provider but for this service you have to pay, its not free!
More detailed instructions you can find in this how to article from Toshiba:
[How to clean the cooling system of a Toshiba notebook? |http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=40]
As you can read, the notebook should be cleaned every 3-4 months and believe me, you will be very surprised how much dust come out ;)
Last but not least its also important that you only use display drivers from Toshiba.
I had also a problem with overheating and this was caused due a wrong display driver (I used the drivers from nVidia page). They are not pretested and dont have an overheat protection The result was overheating and turning off.
After installation of Toshiba display driver the problem was solved.

Extremely high memory usage on ideapad u310

Hi all,
I've got a problem with my ideapad u310 touch running windows 8.1. When doing completely nothing (just staring at the desktop with no programs running) my laptop uses ~55% of ram. I find this extremely high, when i open a few chrome tabs and listen to some music, maybe open a powerpoint it even rises to 80+%. My Medion erazer laptop(also running 8.1) with 4GB ram uses ~65% with the same usage and ~35% while doing nothing. I deleted almost every lenovo programm except energy management and OneKey recovery and i disabled as much programs as possible on startup but there's almost no difference.
Now, I don't really care about the high percentages but what I do care about is that it gets extremely slow when 80% of the ram is in use. Does anybody know what i can do about this? I already tried the refresh windows option but that didn't help. Or am I just stuck with a device that has very very very poor multitasking performance.

hi spromper,
Welcome to Lenovo Community Forums!
Opening Task Manager will show you which application utilizes the RAM.
Also Doing a clean boot will help on freeing up RAM

Extremely high memory usage after upgrading to Firefox 12

After I upgraded to Firefox 12, I began frequently experiencing Firefox memory usage ballooning extremely high (2-3GB after a few minutes of light browsing). Sometimes it will drop back down to a more reasonable level (a few hundred MB), sometimes it hangs (presumably while trying to garbage collect everything), and sometimes it crashes. Usually the crashing thread cannot be determined, but when it can be, it is in the garbage collection code ( [https://crash-stats.mozilla.com/report/list?signature=js%3A%3Agc%3A%3AMarkChildren%28JSTracer*%2C+js%3A%3Atypes%3A%3ATypeObject*%29] ).
I was able to capture an about:memory report when Firefox had gotten to about 1.5 GB and have attached an image.
A couple of things I've tried. I have lots of tabs open (though the Don't load tabs until selected option is enabled), so I copied my profile, kept all my extensions enabled, but closed all my tabs. I then left a page open to http://news.google.com/ and it ran fine for several days, whereas my original profile crashes multiple times a day.
I also tried disabling most of my extensions, leaving the following extensions that I refuse to browse without:
Adblock Plus
BetterPrivacy
NoScript
PasswordMaker
Perspectives
Priv3
However, the problem still happened in that case.
Don't know if any of this helps or not. I'm looking forward to trying Firefox 13 when it comes out.

hello, thanks for reporting back with detailed information.
from a brief look at your extensions i don't recognize any known (to me at least) memory leaking ones. in the last weeks there were also reports about the java plugin causing high memory consumption in combination with firefox 12 - in case you have it installed in firefox > addons > plugins try disabling it for a few days & test how firefox is behaving with many tabs.
& although probably not related to the memory problems you could update your graphics driver to get better results with hardware acceleration in firefox - this is the latest driver by intel for your model & os:

Poor battery life and high temperatures on MacBook Pro Retina 15"

I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
I took it in for service and they told me it needed a new logic board and replaced it. When I asked why they were vague about the reasons, they said "it just needed one, it failed some test". I now have the computer back and it runs the same way it always did. I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing.
"The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor. Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy. I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two. I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life. I will have to time again.
Anyway most people (including the sales guys) are telling me no way this is not normal. When I play with demos in the store browsing the web they are not getting warm or hot to the touch. My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
I installed iStat Pro so I could check the temperature and fan speeds. I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy. I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing. (I also may have viber and skype open but that shouldn't matter). CPU usage is usually running between 2-10% as this is all happening to.
Furthermore, straight from the specs:
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading. Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated. I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing? Especially with only one screen activated (be it it the internal or an external)?
What should I do here? When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info".

Yes I have.
Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink. I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
Seems like a lot of heat for doing nothing. Not only that but I have these problems with no external monitor while on battery power too.
I don't know what to do. They already replaced the logic board. Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

Mbp late 2014 very high temperature at internet videos

Hello,
I bought an MacBook Pro 13" about 3 weeks ago. After some time, I noticed that the Macbook got very hot while watching videos online. I installed "Istat menu" for reading the temperature sensor's values. When i watch videos online (e.g youtube/facebook) the temperature goes up to about 90°C in only a few seconds-a minute. Since you can track apps with higher energy consumptions in yosemite (10.10.1) i looked into the activity monitor and it said the webbrowser (tested with safari and chrome) consumed up to +300 units. If i set the fan to turn on max RPM and hold the MB completely up, i get the temperature down to about 60°C, until i close the youtube/facebook tab completely. Amazon prime video in 1080p works without getting hot at all, even when the Macbook rests on a blanket. Sometimes even spotify (not even playing music, just running in the background) causes high temperatures, but AutoCAD and other programs work "regularly", without the MBP getting hot..
That circumstances really disturb the useability, because almost cant watch videos at all!
I ran the "Apple hardware test" (pressing "D" while startup), which did not give any problems/errors.
Is this a Yosemite problem or a hardware problem?
sincerely ttopueth.

Neither. Some videos will produce temperature in the 90°c range. That actually is 'normal' and is not dangerous to your MBP. There are thermal shutdown provisions that will prevent the MBP from committing Hari Kari. If you wish, get a cooling pad to lower the temperature a touch.
Ciao.

MacBook Pro (mid 2012) reaches quite high temperatures. Is this normal?

I'm currently using a mid 2012 Macbook Pro with the 15" high resolution screen add-on (it's the model that was released alongside the new retina versions). The processor is a 2.6 GHz Intel Core i7.
I've seen a lot of claims about MacBooks running at high temperatures, but I've hardly seen numbers as high as mine. I've had my MacBook reach 100 °C (212 °F) up to 105 °C (221 °F) in some situations (such as when compiling software). I've seen 105 °C being reported as a critical temperature at which the system might decide to shut down to protect itself, so I'm worried that this might be an unnatural temperature and that it might be affecting the lifespan of my PC.
I've also experienced cases where, while being on charge but idle (or running non-intensive tasks such as text editing or watching non-HD videos), the PC would at some point begin spinning the fans to very high speeds and reaching temperatures between 85 °C (185 °F) and 95 °C (203 °F). The aluminum body of the computer gets very hot (especially near the hinge where the screen is attached) and in some cases my fingers can feel the unconfortable temperature even when just typing on the keys. I should note that this is happening during the summer, during which the temperatures outside float around 32 °C (89 °F), but I'm still worried it could keep happening later on during the year.
My warranty is expiring in a month so I'm wondering whether I should get my pc checked before it's over.
What do you think about these temperatures? Is there anything I should worry about? Should I contact Apple?

You can ship your MBP for examination and servicing by contacting Apple, but you will be without the MBP for a period of time. First determine you warranty status:
https://selfsolve.apple.com/agreementWarrantyDynamic.do
Create a time line of MUST dates for shipping and/or a trip to an Apple store.
In the interim, lets see if we can do something positive. In addition to what I suggested earlier, run an Apple Hardware test:

You may have to use OPTION D to start it.
Ciao.

High temperature after suspend to RAM with linux-3.9.2-1.

After the update to linux-3.9.2-1 my laptop works on higher temperature after resuming from suspend to RAM. Works fine with linux 3.8.7-1.
Normal working temperature is 47~49 degrees Celsius and after resuming it is 59~61. It's not just a false temperature reading. I can actually feel the laptop warmer, and the CPU fun spins up.
I can't see any CPU high load. I tend to believe that the temperature rise has to do with the Intel GPU driver (i915). My CPU has an integrated GPU.
Intel(R) Core(TM) i3-2350M CPU @ 2.30GHz
VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
cmdline:
i915.semaphores=1 i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 aspm_force=true acpi_backlight=vendor intel_pstate=disable
Anyone noticed something similar?
Ways to debug it? Apart from kernel GIT bisect.

I got the impression myself, that all the i915 downclock tweaks have been getting counterproductive over time as the driver got better.
Be sure to give the new pstate another go. I had problems too with the upgrade to 3.9.x and the powersave governor. Enabling "performance" in cpupower only and letting intel_pstate manage the idling on its own had an awesome effect. I only have rc6=1 and "sna" accel along with it on a similar cpu. Resuming with fan off.

Used - 1.82 GB
VM size - 198GB
The page ins and page outs have 0 bytes/sec in the parenthesis even though the numbers are so high.
Any help anyone could provide would be greatly appreciated!!!

You difinately need more ram. 2gb is the bare minimum to run just the Lion OS, anything extra will slow your Mac to a crawl. Upgrade to 8gb from either Crucial http://www.crucial.com/ or OWC http://eshop.macsales.com/
And you will be a happy camper!

File size extremely high for .avi after render PE 9

I'm very new to PE and have tried to learn quick to redact info (faces etc) in .avi files for a government agency. I was able to open the file (in the trial version) and make the track matte by dragging the original file to the timeline then dragging it again to the video 2 timeline for the top layer, Question 1) is this the same as copy and paste or am I doubling the size already? Anyway, I was able to get the matte and everything done. Now, to Render and save... I choose computer/avi again (I need to keep it the same) and it took 1 hr 45 min to render it, that seemed long to me but maybe not... but mainly the file size was then 100,883 kb! Starting with a 29.7 kb file. This is what my question is about....could this be right? I can't use it if this is what I get. So, here are the particulars as I got G-spot and looked it up, as per serveral suggestions I saw here. I'm trying to understand the CODEC info but I fear I have a ways to go before I can figure out what I did wrong. (This is my test computer, the future work would be done on a newer, better computer). The videos I would be working with come from various sources and will vary in length but will probably all be a kind of avi.
Intel Pentium processor 1600 mhz
221 mhz, 2.00 gb ram
Microsoft windows xp sp3
video:
length: 0:27.261
frms: 817
Kbps: 28770
pic: 720x480
codec: dvsd dvc/dy
I appreciate any help you can give

Thanks for you response and the information was very helpful. I was able to choose and output that gave me a good file size and I do want DV-AVI (I don't remember what I chose but it worked) but, I don't see an option for DV-AVI - is that a general DV output selection, because there seem to be numerous (AVCHD, NTSC, DV STANDARD) acronyms (I have tried to understand what each is) which do I want?

For the use of Track Matte Keying, with say a Gaussian Blur, or maybe Moasic Effect, if you have not altered the In & Out Points, then just dragging the Asset to both Video 1 and Video 2 will work fine. If you HAVE adjusted the In & Out Points, you can just click-drag from the Source Monitor, where you set those In & Out Points, and all is good. The Copy/Paste is just another way to do it.
As you are doing an "overlay," the output File Size will not be affected in any way. You are also limiting the Blur, or Effect on Video 2 to just the area "exposed" by the Track Matte, so the pixel count will not be altered.
As Steve points out, the output CODEC in the AVI will determine the output File Size. File Size is basically determined by the Timeline's Duration and by the Bit-Rate of the output file. With DV-AVI, that Bit-Rate is pretty well set, and your Timeline determines the Duration. At ~ 13GB/hour, a DV-AVI will be pretty large, but that is the nature of the beast. Also, and as Steve points out, if you are going to do additional editing, and will be Importing that file into a New Project, DV-AVI is about as good, as it gets.
Good luck,
Hunt

Extremely high latency from 4am - 12pm in Baltimore, MD

Lately for the past month I have been getting extremely high latency 1500ms+. I am directly wired to the Actiontec router using a new cable on a confirmed working lan card. I believe the problem maybe at the POD card. How would I go about proving to Verizon without going through numerous transfers of people that don't have a clue?

I had the same problem since Mid-June. Seems like it's anywhere in North Eastern United States. I myself is located about 20 Minutes from Washington DC. I get the latency right around 12~50 ms on first hop to Google or verizon.net on a good day with trace route test. The people in Verizon tells me that's normal but I don't buy that because my neighbor gets around less than 20 ms, never higher. It gets progressively bad around prime time and onward. Around 12 AM it can reach from 100~400 ms on latency to Google or verizon.net server.
I am a late night gamer and need that low latency badly. Seems like most of the people I have talk to from FSC (Fios solution Center) had no idea what is the difference between Bandwidth to Latency. They just call it "Speed". I have spoken with these people for almost every night for a month and a half, when I get a hint that they have no idea what they're talking about, I just hang up and call another one up or just request a supervisor to speak with.
Here is my trace route result, I have highlight the part that are unacceptable.

Trace complete
I'm going to list the things I have done so that perhaps if you are having the same issue, maybe you can anticipate or maybe save you time with this issue.
Replaced Router
This will be my 3rd Router in my possession. The odds of having 3 bad routers are astronomical but yet FSC will try to keep sending you more.
Replaced coax cable (twice), ONT, and splitter.
Once again, the problem still persist. To get these fix, I had total of 4 dispatchers. From the word of their mouth, they stated it's beyond their level and when it comes to latency the tech at verizon server will be the best people to help you.
Reset ONT by unplugging it for 5 minutes or more to pull up a new Gateway IP.
Appearently, someone were able to fix their latency issue this way but the results are mixed. Either it's a permanent fix or temporary fix or it made the problem even worse.
Optimizing connection/wired connections
I have a gaming PC, when they ask to clear the cache to solve my problem, it's an insult. Not only it's irralavent, in order for the computer to bog down because of cache overload, I must possess a computer that is less than of Pentium 2 back from 1995.
Anti-virus and FireWall
If these were actually the source of my problem then the high latency should be constantly bad.
Potentially hacked or other connection to your router.
While this problem can be an issue, I can see who uses the internet and even turned off the wireless. There's no way an uninvited person can slow down my connections.
The server that I am connecting to such as website and gaming server is not guaranteed by the verizon.
Yes, that is true but what are the odds of having google, verizon.net, altavista, gaming server from Steam, etc are having the latency issue all at the same time? It is as if they are blaming traffic problem on I-95 for having bad congestion on I-66. It's not relevant at all!
Verizon in-home Agent
Must I continue?
I will now list the solutions that others have found. Please keep in mind that these problems may not be relevant to you.
1) Bad PON card
Good luck convincing the verizon that this is the issue. For this to be the issue, people from your neighborhood must experience the same problem. Sadly, the problem is the latency and most people will be completely unaware of the problem as long as they are "online". There were cases where group of people resolved the problem but unfortunately the problem came back again the next day because the network tech at Verizon decided to switch them back to the old one.
2) Faulty hardware on rack
As far as I have been told, couple claimed that this has been the issue and was permitted to move their line into another rack.
3) Switching Gateway IP
One have claimed that certain Gateway IP they have been assigned are bad. For example, the house you're trying to drive away from has a huge pothole so you have to go around it by taking a detour.
4) Resetting the ONT by unplugging the battery
There has been claim that doing this for 5 mintues clears it up. What this actually does is it allows you to get a new Gateway IP and re-establish connections.
5) They blocked my IP
Yes, this can happen. I have been blocked once or more perhaps because sometimes I like to purchase and download games from Steam. When I do download, it does so for about an hour to 3 hours depending on the size of the game. Whilst this is going on, my room mate watches movie on Netflex and perhaps download music on the side. Also I watch On-Demand (requires internet). Also not to mention sometimes torrent and other P2P downloads. Check to see if you are blocked.
6) Last but not least, Verizon is purposely gimping our latency to squeeze budget.
There has been talks and speculations that since many primary account holders are not advance users. In otherwords, many would settle for just being "online". This supports the claims for having such a low standard for latency management in verizon. If so, Verizon must stop advertising their "fast" gaming gimmick that they display on their commercial.

High temperature problems with macbook pro 13"

hello all
it is my first macbook pro i am new on macOS, i i bought it since 5 months at Appel store
MacBook Pro
Retina, 13-inch, Mid 2014
Processor 2.6 GHz Intel Core i5
Memory 8 GB 1600 MHz DDR3
Graphics Intel Iris 1536 MB
Software OS X 10.9.5 (13F34)
however i remark when i play on Facebook game like criminal case or show video on youtube it seems that my laptop gets high temperature and my battery runs out quickly, is it normal behaviour ? i need advise there are any application can show me what internal temperature of my laptop ? what can i do to resolve this situation

is it normal behaviour ?
Yes. Videos are processor-intensive actions, and gaming is even more so.
There is nothing you need to do, other than provide adequate air circulation so that the MBP can dissipate heat properly. The aluminum case is specifically designed to do that, so it's normal for it to feel quite warm. Don't use cases or "skins" because they will impede heat dissipation, and don't be tempted to install some clever hack to make its exhaust fan run faster. That will just draw more needless dust inside.
If the MBP gets too hot it will reduce its processor load automatically, and if that fails to reduce its temperature it will simply shut down on its own.
You should consider upgrading to Yosemite. It's completely subjective but all my portable Macs seem to run cooler with Yosemite than they did with Mavericks. Their battery life is much greater though. That's not subjective, I measured it. If the battery life is greater they are almost certainly running cooler.
Back up your Mac prior to upgrading OS X, as a precaution against the unexpected. To learn how to use Time Machine read Mac Basics: Time Machine backs up your Mac - Apple Support.

Extremely high 3g traffic since updating my iPhone 4 to iOS 5

Hi!
Since I updated my iPhone 4 to iOS 5.0 I recogniced that my device is generating extreme high amounts of traffic on 3G.
Sometimes 60MB each day (= 1,8 GB traffic per month, but only 1GB data option, could get expensive)!!! Before updating I had this traffic in about a week or so.
I have already shut down ALL sync services, I am not logged in to GameCenter or other services.
Before updating to iOS 5.0 I also used Twitter & FANCY and so on, these apps generates a lot of traffic when using them several times each day.
Now I have already deleted Twitter and FANCY and some other apps and anyway the traffic generated by the OS itself is really huge!!!
Anyone has the same problem or anyone can help me finding the reason for this high traffic in iOS 5.0??
Also some location services are permanently running and are killing the battery within a day... Why are they always turned on?
Now I turned off all location services and the battery life is still bad - only 1,5 days with low usage (former 3 or 4 days)...
Please help!!
Thanks in advance,
Wolfgang

Hi Urs
I searched a lot and maybe found a part of the reason for this high data traffic.
I'm synchronizing my contacts, calendar & reminder with iCloud & my mail with Hotmail.
When push is activated for Hotmail, that doesn't matter, but when push is activated for iCloud, the amount of data nearly explodes. So I turned iCloud to manual and let Hotmail on push.
Contacts, calendar & reminder are synchronizing when opened (I think this is enough).
Also I do a backup on iCloud and than I deactivate the function (I do not delete the last backup, I only deactivate the option for automatic backup).
It seems, that the backup functionality also generates traffic when not on WiFi - especially at night!!
The battery life has been getting better, when I deactivated the support for automatic time zone changes (location services were always on).
The battery finaly got MUCH BETTER since the update on iOS 5.0.1.
My traffic is actually higher than on iOS 4 but not so high as before I deactivated some services...
I hope this info is a little help for you!!
Let me know if this works for you, ok?
Best regards,
Wolfgang
