core duo temp...

ok i downloaded it for the first time and i noticed the temp was 58 degrees. so i was like wow thats not bad...then i saw the C. celcius. so i changed it to farenheit (obvioulsy the metrics we use in the USA) and its 136.4 degrees. isnt that really hot? why does everyone go by C? does the lower # make everyone feel better? im confused.

MacBook Pro, 2.0 GHz 2GB RAM OS 10.4.6 - iPod video 30GB, Mac OS X (10.4.6), iMac G4, 1GHZ and 512 MB APPLE RAM. OS X (10.4.6)

🙂 CoreDuoTemp comes from France.

In Europe, Asia and Australia, we all use Celcius for temperatures. It actually makes better sense than fahrenheit.

ie 0c = freezing point of water
100c = boiling point of water
20-25c is a comfortable room temperature

Point is, doesn't sound good for the CPU to run over 100c !
(most people report that their MBP CPU temps peak at 90c at MAX CPU utilisation and then the fans bring that down to ~85c. Pretty hot, but within specs )

First of all, let me apoligize to everyone out there. Some Americans dont realize that we are the minority in using the standard system for measurements. And that there are many advantages to using the metric measurements.

To answer the question....the chip can handle 100C, or for you 212F. And yes that is a little hot (duh)...but it is built to withstand UP TO that much heat. Just like kitchen untensils are built to withstand certain amounts of heat.

Steven, the Centigrade temperature scale is used in much of the world instead of the Fahrenheit scale commonly used in the U.S.

But even in the U.S. the Centigrade scale is used in science and engineering.

Every computer chip has operating temperature specifications, a range of temperatures within which it will operate properly and meet specifications for its operating lifetime. The Intel CoreDuo used in the MacBook Pro is specified to operate safely at temperatures up to 100 C (212 F).

Your computer has sensor circuitry and associated software that keeps the CPUs from exceeding the maximum safe temperature.

Don't be put off by the "boiling water" temperature. Doesn't really mean anything. Your home heating furnace likely operates with a really hot gas or oil flame. But no matter how hard it might try, your furnace can't heat your house to such a temperature (unless it sets your house on fire). 🙂

Your CPUs cannot heat the computer's case to 100 C; the case may feel very warm but you cannot receive a burn by touching it for a moment. I use an aluminum tilt stand whether my computer is on my desk or in my lap, and am perfectly comfortable. Yes, I can use the MBP as a laptop and in a way that follows Apple's guidance on page 107 of the user guide.

My MBP doesn't have a heat problem. It operates very conservatively inside the temperature specifications. The portions of the computer that I need to touch to operate it -- the keyboard, trackpad and rest areas left and right of the trackpad -- stay comfortable for me to work on it all day (and I do work long hours every day). That's also true of my hard drive. It stays comfortably inside its design specifications for temperature.

My MBP doesn't need the "grease fix" as it operates very well as designed by Apple. I can easily generate temperature graphs that compare with those posted for computers that have had thermal grease reapplied, displaying temperatures lower than some of those. I feel no need to void my warranty by disputing the design and manufacturing specifications certified by Apple's engineers.

My MBP also operates within the specs of Apple, hence nothing wrong with it. The emphasis on the heating issue is not that the machines doesn't life of to the specs. The emphasis is that the machine gets darn hot, even with two fans. That's equal to bad engineering. This is not rocket science. How come that IBM/Lenovo can make much cooler machines, using less fans. A partially answer is that Apple uses an aluminum chassis, which lead the heat better than the plastics, making the case hotter. This however, does not explain why I cannot place my finger on the back left bottom for more than a few seconds.

I knew about the heat problems before I bought my MBP, as i thought i could cope with it, and I actually can (although I'm afraid that a table some day will be damaged or miscoloured due to the MBP). I love this machine, but I seriously wonder why they cannot/will not do it any better.

The fastest processor you can get in a ThinkPad at the moment is 2.0 GHz. The highest video is ATI X1400. These both produce less heat. Also, the Macbook is very thin, a stylistic decision, not an engineering one. My guess is the engineers had to figure out a way to make it work, and keep the general dimensions the same as the G4, so they had there hands tied so to speak. The ThinkPad, or whatever they are calling it these days, is somewhat thicker.

Try and see if there is a way to under clock your CPU to 1.8 or 2.0 GHz (the IBM options), and under clock your video. That might produce heat ranges around the same as what you’re seeing from IBM. My guess is if you find a way, you probably won’t do it 🙂

If that’s true, then the tradeoff Apple made to give you a more powerful machine (heat), you find acceptable too.

Cheers!
