Intel Core Duo 2.26 GHz Core Running At 100 Degrees Centigrade

Forgive me if this is in the wrong section.
I purchased a 13" MacBook Pro back in April. I've suddenly noticed that the CPU is getting entirely hot. I mean really hot, to the point where this thing might burst in flames.
Often, I have over 50% of CPU availability, so I know it's not the CPU working "too" hard. I have installed an app which has measured the core temperature at 100 degrees centigrade. I know this can't be normal.
I'm coping right now thanks to an application called smcFanControl (which is bringing fan speeds to 4000rpm), but if I'm out and about I cannot have this fan running that fast or I'll be out of battery in less than an hour.
Any thoughts, suggestions?

Computers run hot when they are doing work.
Your computer has a series of temp sensors that will shut it off when it exceeds the maximum operating temperature, this is called an overtemp. 100 degrees C is hot, but without the use of SMCfancontrol do your fans kick up automatically?
Oh, and 100 degrees is not going to cause your computer to burst into flames, I promise.
In Activity Monitor, what apps are taking up CPU power? Sometimes you can have a software problem causing some process to go nuts and it isn't at all hardware related.
Other times, your SMC settings (system management controller -- chip on your logic board that controls power, fan speed, and many other things) can become corrupt in which case your fans may not spin up as needed.
You can reset your SMC and retest, see if that helps. If it is a MBP with an integrated battery, do the following:
Power off the computer, plug in to wall power.
Press Shift + Control + Option + Power Button, for a second or two and release them all at once. If your battery wasn't fully charged, you'll see the magsafe light go from orange to green and back to orange. Then power back up and retest.

Which O/S upgrade is recommended for a MAC Book Pro17 with Intel Core Duo 2.16 GHz

Which O/S upgrade is recommended for a MAC Book Pro17 with Intel Core Duo 2.16 GHz
I am using os x 10.4.11.
Do I need to upgrade to 10.5.xx? Will this platform suport 10.6.xx? If 10.6 will work do I need to install 10.5 first?
Thanks...

Hi. Your computer can be upgraded to either Leopard 10.5 or Snow Leopard 10.6. 10.6 will be much easier to find and will be less expensive. Leopard is not required prior to upgrading to Snow Leopard.

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.
I use wireless to connect to the Internet and everything works fine when I sign on. After being on line for awhile and my remaining battery power at about 60%, I lose connectivity. I turn off Airport, restart it, and I am asked for my secure password. I enter the password but cannot reconnect. So, I shut down the computer for 5 to 10 minutes, restart, and everything works great again.
Has anyone experienced this behavior and do you have any suggestions as to what is causing the problem.
Thanks for any help you can give me.

I think I hit the wrong key ... so here it is again!
Thank you ... I keep seeing this i5 and i7 processor mentioned and it is also recommeded that I stream using it. Do you have any suggestions on which MacBook would serve me better? Or is there an upgrade of any kind that will help me?
Thanks again.

I take it that my Intel Core Duo (2 Gz) will not run Lion - correct?

Incorrect.
Where did you get that information?

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer?

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer? Thanks for the input.

Intel Core Duo is a 32-bit processor, so the latest Mac OS X version you can install is Mac OS X Snow Leopard -> http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
You are running Mac OS X 10.6.8, so you are already running the most recent Mac OS X version for your computer.

My new iMac 27 i7 quad core (early 2011) is slower than the iMac 21 core duo 3,06 ghz (late 2009).

hello i've just bouth my new imac 27" ( spring 2011) with quad core i7 3,4ghz 4gb ram and 2gb ati radeon graphics..
I've proceded with the migration assistent and just copied my old configurations, programs and datas from the old one ( imac late 2009 27" 8gb ram intel core duo 3,06 ghz, 256mb ati radeon graphics) to the new one...now they are twins with boot lion 10,7,2..what i've just discovered? that the old one is a litttle faster than the new one.
photoshop is opening faster
and more or less all the adobe suite..
is that a joke? how is that possible? i can think that the issue is all about the RAM (4gb new imac, 8gb old imac)..
could someone help me please?
thankyou.
Andre

As far as I am aware iMacs do not have upgradeable CPUs.

Core Duo 2 vs. Core Duo - Battery Power

Hey all,
I was wondering about battery power. Yes, they just upped the MB's so soon after they came out ut whatever, the only two things I'm concernend about are architecture, and battery power.
After I ran the fan augmentng firmware update I'm lucky to get 3:40 out of my MB. And they were advertised at what...5? The new ones are advertised at 6. So what do you all think, any real difference there?

Actually the battery power of a MacBook was advertised at around 4. I think you might have been getting mixed up with battery power, and how many times faster the MacBook Core Duo and the MacBook Core 2 Duo, are faster than the iBook.
The MacBook Core Duo is 5 times faster than the iBook. The MacBook Core 2 Duo is 6 times faster than the iBook. Also I am not quite sure about the battery life on the C2D's.

Mac mini Intel Core Duo fan very loud and runs at high speed all the time.

I purchased an "Open box" Mac mini Intel Core Duo, 1.66Ghz, 2G ram, 80G HD and SD a few days ago from Fry's.
It runs beautifully except the fan is very loud compared to any Mac my family has ever had. It is so loud that we were thinking of putting it under the desk.
The fan runs constantly, and I mean all the time, at a high speed. You can really feel the air coming out the exhaust vents. The case is always cool to the touch as is the exhaust air.
My aunt bought a similar Mac mini (But only 512Mb ram) the same day. Her's is very quiet. The case feels just slightly warm, not unlike other Mac mini's I've seen.
Should my Mac mini's fan be running this way?
Thanks,
llulua
BTW: The "open box" was sealed with a Fry's label and it said that this had a new warranty. Yet, checking the serial number, it said that it had about 260 days left. I guess Fry's is backing it?
Also, someone told me that perhaps the main wire from the fan to the logic board is disconnected.

eMac 1Ghz, iBook 500 dual usb, Mac mini 1.66Ghz Intel Core Duo 2g ram Mac OS X (10.4.8)

Since you have 2 gigs of memory, my thoughts are that when the party (Fry's or the origianl purchaser) upgraded the memory, they neglected to reattach the wire at the front of the Mini under the IR receptor at the right front corner that regulates the fan speed. This wire must be unattached in order to upgrade the memory, and is probably why the original person brought it back, because of the fan noise resulting from failing to reattach the wire. If that wire is left unattached, the fan runs continually at high speed to protect the CPU and system in general. If you do not want to use a putty knife to open the Mini, take it back to Fry's and ask someone who is Mac savvy to open it and reattach the small plastic receptacle at the end of the wire into its socket at the right front of the machine. When I go to Fry's, I am always concerned because the employees allow people to pry keys off of the Apple notebooks, so don't expect that their employees to know or care about anything Mac.

That memory specification is correct, but the maximum memory configuration for your iMac is 2 GB.

MacBook Pro Core Duo 1.83 GHz fans (0 rpm)

Working on a friends macbook pro core duo 1.83GHz 1,1 - It’s been shutting down intermittently; he’s been using a laptop cooler and it helped some. I installed iStat Pro and SMC Fan Control and neither the left or right fan are spinning (0 rpm). I figure dust bunnies preventing fans from turning; took the top case apart and much to my surprise it looks as though the fans never spun. Ever! Not a speck of dust inside either one. I powered it up and neither even tries to spin; trying to jump start them with a push does nothing. All connectors look solid, nothing burnt.
Any suggestions other than new logic board?

Depends. Are the fans simply not working? Are they connected to the motherboard? Is the motherboard not working? Have you tried
Intel-based Macs: Resetting the System Management Controller (SMC). There may be any number of explanations none of which you can know without taking it in for repair unless you have the repair equipment and know-how.

Trying to install 10.7 on a mac mini core duo that has a core 2 duo cpu

I have installed a core 2 duo cpu (T7200) in an earlier Mac Mini core duo machine. Runs fine, the system report shows the Core 2 chip. When I try to install 10.7 over 10.6.8, however, the installer reports that it cannot install this version of OS X on this machine.
It is possible of course to install 10.7 on another machine and clone that to the hard drive here. But that seems like the hard way, jumping through too many hoops. Surely there must be somewhere in the (list of) plist files to tell the installer that it is OK to put 10.7 on this machine. I've tried a few places but w/o success. Perhaps someone is a good system hacker who knows how to do this? Many thanks,
tony

I agree-- that is a method that is often suggested. I apologize for doing the Yes, but.... routine; I have several other Macs, but I'd have to back one up (or clone it), clear the hard drive, install 10.7 on it, and then go through your suggestion. In principle it seems straightforward. I might have to resort to that. I had hoped that it would be possible for a more software-centric way, of convincing the installer that the machine was OK; Have I missed something here?
I've tried several suggested methods, and the closest so far is to get an installation from a bootable usb stick that looks like it's installing and then I get a circle with a line across it. No error messages.
the machine is a 1,1 original that now runs fine with 2 gigs memory, a core 2 duo (T7200) cpu. and 10.6.8.
I have tried removing the lines in the plist files that require the 3,1 machines, etc. but that has not helped.
If my time was worth more than 10 cents an hour I should have thrown the sucker away and bought a new one. I have an i5 Mini that screams. any more suggestions are most welcome.
thanks

2.16 Core Duo vs 2.2 Core 2 Duo

How do these two machines compare?
2.16 Core Duo with the 256mb video card
versus
2.2 Core 2 Duo with the new 128mb video card.
I'm asking because I'm thinking of getting the 2.2 and giving the my 2.16 to my wife.
Thanks
Steve
PS I don't play games under OS X or XP

The difference between 2.16 GHz and 2.2 GHz is of course too small to notice, but the 2.2 GHz MBP also comes with the new Santa Rosa chipset with a faster front side bus, and reviews and benchmarks have indicated that the difference, while not dramatic, is significant.
The 2.2 MBP also has a new and reportedly better video card. I don't know enough about the extent to which more RAM compensates for the otherwise inferior nature of the older card.
More important, I think, is the fact that the 15" SR MBPs come with the LED backlit screen. My spouse has the older MBP and my screen is brighter and has more even lighting. The LED also weighs less, uses less battery, needs no time to warm up to full brightness and is said to last longer without dimming over the years.
To me, the LED screen is the big reason to get the new MBP. (They're even starting to show up on Apple's refurb page; I saw one yesterday for $1699).
