From what i can read of this and from own experiance the "voltage" referred to is actually dropped to change the clock frequency not the actual working voltage of the cpu, having said this i would need to see the data sheet for the ARM device used in the N900 to be able to fully understand why someone said overclocking is "lowering" the voltage.
Voltage is not the reason you get heat on any electronic component it is actually the current being drawn that creates heat.
Please understand ohms law for this.

Ok then overclocking does not make the N900 get any hotter.
And i can fly to the moon and back in 30 seconds lol.

From that wiki page you gave me the link to ,
http://wiki.maemo.org/Overclocking#U...voltage_tables
i read this....
Undervolting and voltage tables
See: http://talk.maemo.org/showpost.php?p...9&postcount=81
Extract from the post:
CPU power consumption (without constants) = leakage + capacitance + switching = voltage^2 + frequency + (voltage^2 * frequency)
One factor reducing CPU lifetime is the current it is running with.
CPU dynamic power consumption = capacitance * frequency * voltage^2 (wikipedia
ynamic_frequency_scaling)
As can be seen from the formula lower voltage plays greater part in CPU consumption than frequency. By reducing the voltage the damage of overclocking can be reduced and the battery life time extended.
So it goes to prove someone just don't know what they are talking about.
Also read the other post from that wiki page
http://talk.maemo.org/showpost.php?p...9&postcount=81
It is indeed all to do with current and to understand current and voltage you need to be an engineer of some description even to understand ohms law.
Matan is talking out is rectrum i am sorry to say.

Do you accidentally push the send button or...?! Gettin ridiculous 
Useless to ask people to read the whole thread when one user is repeating his quest dozens of times. Hmm.. deja vu!
