hi all, i'm curious what rule you follow with this one. if your done for the evening with your powerbook, but the fan happens to be running, do you close the lid/put it to sleep/shut it down, or do you wait it out for things to cool down via the fans before you power the machine down?

it seems, especially when closing the lid to put it to sleep, this might cause damage, or at least some kind of wear-and-tear, from heat that should be dissipated (hence the running fan) but is not, since the fan is turned off when the laptop goes to sleep. thus the heat remains longer than it should, to gradually warp and melt the tiny bits of solder and other delicate innards of our beloved pbooks.

is this something that anyone else has thought about, or something they perhaps know the absolute answer to?

The fan is to ensure that the heat dissipates as fast as it is being created. Putting the machine to sleep means that the heat is not being created anymore and therefore, it's not a big deal whether the fan is still running. The fan does not keep things *cool* by any human measure of temperature. It's still hot inside the laptop. The processor itself is very hot. It's not even remotely hot enough to melt solder though.

My vote is that you will be fine putting it to sleep.

I close the lid when I want to - regardless if the fans are on or not.
As already said: sleeping doesn`t create more heat.
