Approximately how long can a laptop computer run at its maximum temperatue?

[mobjo23]

My Dell laptop has a max temperature spec of 105 degrees.
It doesn't state how long the computer can run at this temperature..

well they will say all day everyday, but it really should not. high 90s is already too hot in my mind. sure it can peak at 95C for a it, but the cooler you can keep it, the better.

It will run until it dies... however long that may be...

When the CPU gets too hot it attempts to lower the temp by reducing the clockspeed so there will be a performance. How much will the temp drop depends on how well heat is being vented from the laptop. Thermal paste that has gone bad (dried up) will be inefficient at transferring heat to the heatsink which the fan blows on to move heat out of the exhaust vent.

Actually, thermal paste that has dried up will no longer transfer heat. Instead it will be come a heat insulator trapping the heat the CPU generates and makes the laptop nice and toasty on the inside.

Additionally, the excess heat trapped within the laptop can damage other components over time. Not just the CPU.
