Default Re: Undervolting GTX280 - The Way To Be Cool!

the GPU draws power (Watts). Power = volts * amps.
and one thing is for sure.. you do not want a lot of amps thru those small copper lines on the PCB..

take the following formula (law of ohm)

U = I * R

P = U * I ( <-- here you have it. lowering voltage (U) will increase amps (I) on the same load (P) )

P = ( I * R ) * I
P = IČ * R ( also this a dangerous factor. as it is mentioned to reduce heat. therefore lower resistance (R) the higher the amps (I) will be )

does this make sense ?
