Unibody Macbook Pro .. Overheating ?

Hi there

Same here. I just made an upgrade from my older MBP (2.6 GHz, 4 GB, 200 GB) to the new unibody version (2.8 GHz, 4 GB, 320 GB). My old MBP is running at a consistent idle/moderate activity temp of 50 degrees celsius while the new unibody MBP runs at 65 degrees celsius at the same load. In both cases the fans are running at around 2000 rpm.

15 degrees hotter is simply ridiculous!

Hi all,

Maybe this has been covered before, but I didn't see it anywhere. Please point me to the information if it has already been posted.

The processor in the Macbook Pro is the T9600. Correct? If so, the thermal specs show that it is rated to 105C.

The specs are here: http://processorfinder.intel.com/Details.aspx?sSpec=SLB47#

Is anyone getting temps that hot?

There are multiple threads covering the overheating problem. Just two of them:

Folks, today while doing some normal computing stuff such as surfing the net using firefox and using aMSN, iTunes with an average of 50% cpu usage, I found that my computer temp "as shown on iStat" is 72C ! is that overheating ? or is it normal ?

Definitely not overheating. I would say that this is completely normal if you're using the 9600GT. Try using the 9400M for a bit; the temperatures should fall by about 10ºC. You're well within the working range of the machine though.

Indeed yes .. turned my 9600GT off entirely and now the temp is fixed fairly constantly at 50C.

My MBP averages around 40c doing light internet work, and bumps up to the 50s when I crank up VMware or other applications that start stressing the CPU/GPU. I usually keep my unibody MBP on the 9400M GPU because it tends to run cooler and gives me the option of just unplugging and moving around. Otherwise, I'd have to close all my apps and log out to switch the GPU when I want to use the laptop on my lap in the living room as opposed to being hooked up to my desk
