MacBook Pro 17in 2.16Ghz Duo OVERHEATING???????????

All of the Core Duo MacBook Pros I've used were significantly hotter than my MacBook.

It seems the new Core 2 Duo MacBook Pros are cooler, but if you've got an original Core Duo one, then I wouldn't be surprised if it was hotter than your MacBook. That seems to be normal.

Have you run all software and firmware updates to it?

It is normal , in fact I went to the apple store close to my home and touched every MBP over the tables. All of it works hot.
Yesterday ,I updated my MBP with the new firmware and appears to be cooler than before .
Right now I'm writing this lines with my computer over my lap and nothing happened with my skin in half hour.
Sorry for my English but it is not my primary language ,if someone find a mistake try to forgive me.

I noticed the same thing with my MBP- and read in the manual that it is not meant to be sitting on soft surfaces like pillows, sheets, clothing because it blocks the air vents on the bottom side of the book.

On hard surfaces, my darling runs at around 52C and 61C when I'm working on multiple programmes....otherwise, when sitting on my pillow- it gets very hot- around 62C so I try to avoid resting it on places where the air flow might be blocked.

Download this program. It will go into your Sys Preferences and run automatically. It monitors the temperature of your computer and adjusts the Fan speed to cool down the processor. Set the base speed to 1200 RPM, lower Threshold to about 47 degrees Celcius and upper Threshold to 70 degrees.

These are the settings I use and it really works.

Problem solved!

I think I will give it a try.

I recorded a temperature of 84 C just last week.

For those who don't know the metric system, water boils at 100 C.

Sorry to tell you guy, its true the MacBook Pro is a HOT running son-of-cpu. I’ve actually burned of the chrome letters at the bottom of the screen. Using a widget I’ve monitored my 15” 2 GHz to temps over 160°. Try to keep the MBP off the carpet or bed; they insulate the computer like the Pink Panther. Keeping it on a hard surface keeps a little airflow beneath and cools it down. If you’re hardcore like me and need that puppy to push until it dies look into getting laptop cooler or a docking station I know there’s a company developing a workstation for your 17”. The name of the company is Book Endz here is their website. http://www.bookendzdocks.com . I’ve seen their products on a number of sites; they’ve been around since Black G3. The docking station doesn’t have a cooler but it does have a hard surface to get a little air flow.

A side issue: Experts in portable power state that Li-Ion battery packs should NOT be exposed to temps over 130 degrees F.

Which begs the question: For extended sessions on AC power, should we REMOVE our battery packs?

After reading this Discussion, I try FanControle and smcFanControl.
It's both works fine.
Although smcFanControl is much easer to use and unlike FanControl, It does not crash the system (that's what I heard).
Looks cool too.


Wow my hands are very cool now.....

MacBook Pro Mac OS X (10.4.8)

I downloaded this program yesterday and my MBP 15in is running noticably cooler, HOWEVER my battery heath, which was around 97-99% is now 25%!!! Any thoughts? is this a problem at all related with the fan software??

hi Clint,

removing the battery pack will dramatically lower the temperature but...the processor speed will drop to 1Ghz. I personally often use my MBP without the pack and the reduced speed does not prevent me to use Aperture, Safari and iTunes at very decent speed. With the battery pack, I am usually at 60 to 85 degrees celcius and without it, I am typically around 40 to 55C...
I am also using SMCfan, pushing my fans from 1000 to 2000 before rebooting under Bootcamp/Windows (the fans values are kept and still valid after the reboot). No battery pack + boosting fan speed (from time to time) makes my MBP an even cooler machine now !

Bye !

Thankyou very much for the link to this tool. Works great.

Actually got a heat blister on my leg from the computer running so hot during finals week at university. Was chained to my computer for a few two many hours I guess.
