Intel Atom Baytrail heat related questions.

[therr6]

I have a couple of questions about the Intel Atom Z3735G.

1. In the data sheet, it says that the Tjunction max is at 105*C. Does this mean that the Chip will shut down to prevent damage at this temperature?

2. The data sheet says 2.2 w @ 70*C. Does this mean the cpu will be at 70* c at 2.2w?

3. The data sheet says the cpu will throttle itself at 100*C, but the bios may change the throttle set point to 90*C. The data sheet says this its not necessary, so will operating the cpu at 90*C hurt it?

4. Under load, such as playing a 3d desktop game on my Z3735G, the cpu temp increases to about 58*C. Is this too hot for the chip, or is it a safe temperature?

5. Will operating the cpu at 58*C for about an hour kill a transistor, and what would happen if a transistor failed in a cpu or graphics core?

See my answers below:

1. The maximum processor temperature is 105C; the processor will shut down to prevent damage.

2. Correct.

3. If the BIOS throttle set point is different in BIOS then it will throttle at 90C. This is possible only if the BIOS has options to change this settings.

4 and 5. 58C for the processor playing games is an actual safe temperature. The processor has been designed to work at high temperatures
