What is the maximum temperature Core 2 Duo should have?

Question

My laptop CPU is "Intel(R) Core(TM)2 Duo CPU T6500 @ 2.10GHz". I use Ubuntu 10.10 and I get the CPU temperate via 'sensors' program.

During normal operation it reports the CPU temperate ~50 centigrade. But if I run some long running CPU intensive program the CPU temperature shoots to 80 centigrade. And due to fear of burning CPU I do not run the program completely.

And here is specs page from Intel: T6500

Solution

As you can see on the specs page you linked yourself, the Tjunction is specified as 105°C. That means unless your CPU runs at this temperature you are save, and even then the CPU is going to shut itself off if it gets too hot.

Nothing to fear here. Typically in notebooks, the CPUs get rather hot under load which is desired as cooling them down takes much energy and produces much noise, so notebook vendor dent to fully use the thermal budget.

+1 for not being blind like me and finding the TJunction on the chip, haha.

I am not much of electronics guy, so I was confused what Tjunction temperature actually means. Follow-up query is, if I can run my CPU at 90°C for like an hour?

I am planning to use 'pause' within my scripts to let CPU cool down time to time.

You can run your CPU at full throttle. My CPUs got up to ~80-90°C under full load, and I ran them for weeks straight at full throttle. So it's just a question of good system design to keep your system inside the tolerable temperatures. There is no need to keep the CPUs at 30°C. That just costs power and noise.
