Macbook Pro CPU Core's temperature measurments

I have a late 2011 15-inch Macbook Pro OS X 10.8.4 with BootCamp installed.
In OS X environment, the CPU core temperatures are around 40 - 44C, while in idle or with a minimum Safari browsing the net.
When in Bootcamp with Windows 7 Professional, in the similar operating/application condition, but the my Macbook's CPU Core Temperatures are always about 52 - 55C (10 degrees higher than in OS X).
While doing heavy stuffs such as Virus Scan, Time Machine, Data Backup, Video Editing etc ... on both environments the CPU core temperatures could go up to upper 80's degree C.
Is it normal ? if so, is there any explanation for 10 degrees warmer while in BootCamp/Windows ?
Thanks

MacBook Pro (Intel Core 2 Duo 2.4) Failure To Open

I cannot turn on My MacBook Pro (Intel Core 2 Duo 2.4) When I took it to a technician he said he needs Bios for my MacBook Pro. Where can i get it? Please help

First suggestion is to never go back to that Technician, he knows nothing about Apple computers.
Mac computers do not use a BIOS, they use a Firmware, EFI, and there is no way to get into it.
You can get a Firmware reinstall disc, CD, from Apple for your system but I seriously doubt that is why your system is not booting.
From the type of Intel CPU installed in your system it is more then likely a late 2007 or early 2008 model that is more then likely one of these described in this article.

MacBook Pro 15 core i5 and Windows 7

Hi, in new MacBook Pro 15" core i5 4GB ram. I have installed BootCamp with Windows7 (bootcamp driver 3.1).
In "Computer Property" Windows7 Pro 32bit see 4 GB ram but only 2.18 are usable?
Task manager confirm this.
Any suggestion?

There are two problems that are limiting how much of the memory in the machine windows will use:
1) Windows in 32bit mode will only address _up to_ 3GB of memory. With 4GB of memory in the computer, windows 32Bit will use _at Max._ 3GB of it. The only way around that is to migrate to windows 64 bit.
2) Any system needs (like shared memory for low end graphics cards) subtracts from the maximum the computer recognizes. The i5 processor based Macs list two graphics cards in them (Intel HD Graphics & NVIDIA GeForce GT 330M). The Intel HD graphics uses a fair amount of shared (system) memory, so it will pull what it needs from the "3GB" leaving you with less. I'm sure there are other system needs that are pulling the number down further, hence your 2.1GB usable. On the Mac side you can probably choose which video card you use through system preferences. On the Windows side, Microsoft announced a while ago they wouldn't support this kind of system configuration (multiple dissimilar graphics cards), so my guess is in Windows 7 both graphics cards are "on" (because Win 7 doesn't know how to turn one off) and the Intel graphics is pulling the required memory from "shared" memory, even though it's not being used. This problem with running windows on a MBP with two video cards has been known for about 2 years and it sounds like Win7 didn't fix it. Having both cards running under Windows has also been known on older MBP models to generate a lot of heat and cause the battery to drain quickly.

Macbook Pro (2GHz Core Duo) won't boot while ANY internal DVD attached

15" Macbook Pro 2GHz Core Duo (2006-7)
Hi all -
I'm having trouble with this macbook pro... it runs perfectly fine, as long as I do NOT attach any DVD-drive/Superdrive to the logic board (internal drives). However, if I attach the correct drive (confirmed working part) to the logic board... when I go to power it on, it attempts to start but almost instantly dies/turns off. You can hear the HDD start to spin up, but nothing else. If I hold the power button (like using the reset technique), it repeats that rapidly with a strange sound like the power is disrupted. Winding up sound... quickly, and repeatedly. Never powers on though and no screen response.
I'm assuming something is wrong with the connection site on the logic board, so I'm wondering what else I can do to have an internal optical drive. I notice a plug-in port (smaller) to the left. Is that a usable port with the right flex cable?? Or somewhere else on the board perhaps besides the connection site for the HDD? Thanks in advance.
J

I actually don't know. It might be worth a close examination of the logic board socket with a good light and magnification. A poster on the PowerMac G4 forum found a tiny resistor in the RAM slot that was causing problems, and later found a missing resistor on one of the RAM sticks. Everything is a lot tinier on a MBP socket, but if you can spot any kind of foreign object that might be causing a short, you could attempt to blow it out with compressed air.
I believe there is a kit that allows you to replace the optical drive with a second hard drive. Don't know if the second socket is for that or something else. Just a speculation--I really don't know but it has to be there for a reason.
Good luck!

Where can I find directions to replace the internal HD on a MacBook Pro (Intel Core 2 Duo, 08/08)? Considering the age does it matter ATA-300 or 150?

Wireless N upgrade for Macbook pro Intel Core Duo (Purchased 8/2006)???

Firstly, I am a little angered that apple has not come out with any directly supported options to allow people with my macbook pro to upgrade to the new wireless N capability.
Therefore I have found a 3rd party option that is being offered by fastmac (http://fastmac.com/ncard.php) that will allow for wireless N wifi.
My only concern is if having this installed (professionally by them or by an authorized reseller, say compusa) would cause my entire applecare warranty to be voided or just the part that covers the wireless card. I could deal with having the wireless card voided as it would be under warranty by fast mac...

Your warranty is not voided by installing the Airport card. However, any damage that may be caused by the installation of the card would not be covered under the warranty.
Secondly, the Airport Extreme card that supports 802.11n is available as an upgrade kit for Mac Pros. Some Apple dealers may be able to obtain and install the card for you in your computer.

But it's covered by Apple's warranty - if you ask, they should erase & reinstall OS X then if it still panics without adding any 3rd party software, there has to be some problem with the computer.

My computer is a MacBook Pro Intel core duo, and I need to know if I can run the new Lion OS?

My computer is a MacBook Pro Intel core duo, and I need to know if I can run the new Lion OS? The Apple web says must have Intel Core 2 Duo. Please advise. Not knowledgeable enough to know if not having the 2 between Core and Duo is a stopper. Appreciate any guidance.

The difference between a Core Duo and a Core 2 Duo is a show stopper when it comes to running Lion. The Core Duo is still only a 32 bit chip, but the Core 2 Duo is a 64 bit chip. You need the 64 bit chip to run Lion.

Powermac G5 Dual Core 2.0 GHZ or Macbook Pro Dual Core 2.0 GHZ

I have a Macbook Pro Dual Core 2.0 GHZ that currently has 1 GB of RAM in it. For the most part it runs fine, but I do come into problems with it sometimes while I'm doing video editing which is my main usage for my computer. I currently run Final Cut Studio 2. Would it be worth it to sell this computer and get a Powermac G5 Dual Core 2.0 GHZ or 2.3 GHZ and upgrade the RAM to 8 GB to help my video editing run smoother? The reason why I am considering this is because I would like a computer that would work better with my video editing at a cost that I can afford. I also would like to have a firewire 800 port for my external hard drives. I rarely use my internal hard drive, so that is no factor in my decision. Currently I cannot afford a new Mac Pro, but will be buying one in about a year. I'm just trying to decide if this would be a good switch for right now. Thanks for your help.

Although I don't own a Mac Pro, rumor has it that they run video chores significantly more efficiently than do the last generation G5's. I bought my 2.3 GHz, w/the 7800 card, for $600, last November on eBay. The case wasn't cosmetically perfect (a rather nasty looking crimp on the front handle) but it has performed well running my video (EyeTV and recording) and academic (I teach math & Mathematica) needs. I picked-up extra memory (it now has 6 Gigs) pretty cheap (around $75, IIRC), from Kingston. I also took the advice of many here and got a WD 640GB HD that made a significant difference in both boot-time and opening applications. However, if you're going to get a new Mac Pro in a year, it's almost like throwing money away - the G5 will probably have its' depreciation rate decrease once the software vendors no longer continue supporting pre-Intel machines. That being said, my G5 is more than sufficient handling my present version of Mathematica - I don't think that paying $3000, or whatever it takes to get a new Mac Pro, would balance the marginal increase of utility I would get using Mathematica. If I were a video guru, I might feel differently. I thought I could give you a definitive yes, buy the G5, because I really love mine. Unless something happens, I plan on having it for at least a few years. At about $250/year, if one figures that I'll have owned it for a total of 3 years, that's less than 70¢/day. But I also value the opinions of many of the posters who have commented on the new machine's speed, compared to the 2.5 GHz Quad, say.

MacBook Pro CPU Temperature Issue

Hi,
My MacBook Pro is becoming excessively hot, even with light usage. Currently, I have Google Chrome, Sublime Text 3, MAMP and Mail open. Google Chrome (36.0.1985.125) is the only app that is capably of heavy CPU (and MAMP, but I'm not developing any intensive scripts at this time), however I only have one or two tabs open. And neither one of them are intensive websites. Usually just PHP docs, and localhost. The average CPU activity is 1.4% System, and 2% User (it sometimes peaks to 2% System, and 5-6% User, but nothing massive).
Right now, the temperatures are averaging at 85C (and yes, that is degrees celsius). It regularly exceeds 90, and sometimes reaches just over 100C or so when just on YouTube or Facebook. I'm not sure if this is maybe related to an inaccuracy in the temperature monitor, but I use this to get the measurements. The MacBook Pro's casing does feel hot, almost painful at times when I touch the aluminium area just beyond the keyboard and below the screen for a few seconds.
The current environmental conditions for the MacBook Pro are:
- flat wooden surface (desk) to sit on
- 18C ambient room temperature
The MacBook Pro is a 15" Early 2013 with an i7 Quad-core, 8GB RAM, 1GB NVIDIA GT 650M (MacBookPro10,1) running OS X Mavericks 10.9.4.
Here's what I'd like to know:
- Is this normal?
- Would if help if I removed the cover and removed any dust (if any)?
- Do I need to take it to a repair shop?
Thanks in advance.

Make an appointment with the Genius Bar at the nearest Apple Store. Have them check your machine. Back up what you want to keep/restore before you go.
You can try another monitor solution that will tell your CPU temp, fan speed, and battery information. It is iStats, a Ruby gem that has been posted a few times in the community. The following image is from a just-powered on 2014 MBA. In the following, if you use Ruby Version Manager, the sudo is unnecessary. It may complain slightly, but does install correctly, as it works fine on my 10.9.4 machine.
$ sudo gem install iStats
$ iStats -h
$ iStats
$ sudo gem update iStats # periodically keep it current

My macbook pro cpu temperature is too high??please tell me correct fact and information

i mistake deleting my activity.......re question...
I'm using macbook pro retina 13inch 2013 late version.
my macbook has NO external graphic card, just iris graphic.
when i was playing diablo3 or watching movie by using bypass ip address, my cpu temperature was maintained 90~100 celcius degrees.
And at the same time, my cooling fan was maintained 5800~6000 rpm.
There are two questions.
One, is my macbook temperature too high or normal level ?
Two, i know that 6200rpm is maximum speed of cooling fan. Why did fan run 5800~6000rpm, not maximum?

When processor intensive activities are taking place, temperature may reach the maximum level.

MacBook Pro Retina Core Temperature

Hi,
I've just bought the new high end Haswell 15" Macbook Pro Retina and have been installing all my stuff.
I noticed that it was feeling very hot so took a look at iStat which showed the CPU at 12% yet all the cores at 60-80 degrees.
Is this normal? Seems very hot to me considering I wasn't really straining the system.
Cheers,
Luke

It's on the Sensors menu of iStat...... since posting that I've seen the cpu tempreture get up to 90 but the fans don't seem to automatically speed up, I ended up manually putting them to maximum which cooled it right down very quickly
