What's a safe G3 operating tempreature?

[Gwailo]

I just got a little utility called ThermoInDock that I'm using with my iMac DV Sage (640 RAM, G3 450MHz).

It reads a relatively constant 40C unless I don't touch it for a while then it goes down to about 36C.

What is the safe upper limit range (from dangerous, to damage causing) that the G3 [in an iMac] can safely operate?

PS I got it at www.macosxapps.com check it out it's pretty neat and I assume it's accurate.

Tip: I've had one iMac overheat once, to cool it down I got an airduster with a straw and if the temp gague (in Classic) went above the red line I just shot some *AIR* (i.e., not frozen propellant into the vent by the handle. Brought it down to 30C in 3 seconds haha.

If you bought the thing new, it should say somewhere what the operating temperatures are (meaning temp of room, not CPU itself).

Ambient temperature where I live can get to 40 C at the height of summer. The CPU must typically run somewhat warmer than ambient temperature, so maybe add 10 C to maximum ambient temperature.

All very rough and based on intuition more than anything, so take this for what it's worth. (Problem with free advice is you often get what you pay for...)
