Thermomagnetic generator to autonomously power watercooling system ?

[Studentman]

Hi,

Improvements of a technology that can generate electricity out of a temperature difference can maybe make it feasible to generate electricity from the difference between de cold water and the warm water in a watercooling system for GPU or CPU ?
I did som calculations, but would like to ask you specialists what the temperature difference of the water before and after the GPU or CPU is ?
And what is the volume flow of the water typically ?
I have no experience using these things, just looking for possible applications of a fascinating technology

Do some research on sterling engines. Also, check out peltier modules. (They can generate electricity from temperature differentials)

The short of it is: not possible. You'd be hard pressed to power a fan \ pump even with say, a wood stove & a bucket of ice. Much less possible with a 65W CPU and a cooler that gets to room temp at best.
