Heat extracted from 470 k or 4750>
Normal usage ( winword, e mail , excel , internet , music etc..) -----
cpu > 54 -57 degrees celcius
hdd > 45 - 49 degrees celcius
Hard usage ( gaming , dvd, burning dvd's , encoding etc..) -------
cpu > 60 - 64 degrees celcius
hdd > 47-52 degrees celcius.
At first glance this numbers might seem a little high ,
however I touched the left pad at normal usage and couldn't barely feel any heat .
I have also talked to a service guy at chiligreen .....
He told me that 50 - 70 degrees would be normal ....
@ 75 - 80 the laptop will have a safety feature and will automatically shut itself off.
Maximum cpu tolerance is 150 celcius if I am not mistaken
Don't take my word on this though
