Is it normal for my CPU to be averaging 75ºC? sometimes 80ºC

I've a 3 windows from FireFox open, Thunderbird and the finder window.

iStat says the following:
HD 34ºC
CPU 74ºC
Enclosure Base 33ºC
Enclosure Base 2 33ºC
Enclosure Base 3 30ºC
Enclosure Base 4 35ºC
Heatsink B 60ºC
Northbridge 47ºC
 
Well, I don't see any temperatures there that would run the risk of damaging your computer. Had it been running long when you copied that data? Normally my iMac shows about 55ºC for the hard drive.
 
ah sorry forgot that. It's a 13" Macbook Pro running OSX 10.6.2 .

Maybe not damage, but they are very high for the usage he has. My identical MBP runs <50º normally and only get around 70º if I have some pretty intensive operations running that take all the CPU. Something's not right.
 
here's a screen shot of my iStat widget while running a flash based video and facebook.


Thanks guys for your replies.

Your temperatures a normal for a middle amount of CPU usage. I wouldn't worry about it unless it goes over 95-100ºC for long periods of time. When I'm encoding a movie for a few hours my temps are in the low 90s the entire time, and have never had problems. It's also designed to turn itself off before any damage can be done from overheating.

Make sure you're not blocking the rear of the laptop so air can come out.

Hey, do you have any idea what the max. operating temperature is for this CPU? I looked once and saw it, but wasn't able to find where it is just now.

I'm not sure the exact processor in the MBP, but the 2.2 Ghz T7500 in my MB is supposed to go to 100ºC. I would think that the MBP processor would be fairly similar.
