Operating temperature - what does it actually mean?

When a manufacturer states an operating temperature, what does that actually mean?

Is it the ambient temperature that the device should work in or is it the temperature range that the actual device can stand?

Usually that's the maximum safe temperature that the component can operate at without receiving damage
Usually if the temp exceeds that maximum value (TJMAX) the cpu goes throttle and shut down to prevent damage

not sure if that's what you were after, but hope it helps

Thats the information I was after.

So just to confirm:

When it states an operating temperature of between 0 - 55*C it means that I shouldn't let any of the internal components get that hot: See fourth page

to be honest i think that just means the environment temperature or ambient temperature

So it is advised that your room temp is between 0 and 55 C

Ah right - so what would be the max temperature for the components then? At a guess...

Drake22 · 3 Sep 2009 at 12:03

max temp for 945G is 99°C

for processor seems 85C http://processorfinder.intel.com/details.aspx?sSpec=SLG9Y

as long as you are under 75 it ll be fine

i doubt any component will exceed 60 though

That's quite hight, I assume people don't usually let it get past 70 odd.

The reason I am asking is that I am currently modding my fileserver and I am trying to get it run fanless so wondering what the max temperatures are before the components start dying.
