k the idea is to use the heat of a chip to cool itself. the picture underneath will shows the set-up.

k so we put a peltier generator between a the cool block and the chip. there is a difference in temperature so it will generate power. we will use this power to let the fans spin. winch will cool the cool block to keep a temperature difference.

if the efficiency of the peltier is high enough we could be able to put a heat pump (like in a freezer and so) on it witch van have an "efficiency" of 300%+ . this means that we need 1 watt to pull 3 watts out of the cold side of the peltier generator. and we will end up whit 4watts at the cooler but a higher temperature difference. so we will use some of the power of the chips heat to do this and add some from the outside or if the efficiency is high enough we could just let it do without energy from the outside.

PS this isn't an idea for free energy it just uses the energy of the chip and heat pumps can have a higher efficiency than 100% because it are 2 different loops you don't make heat you just move it around whit energy.

if there are any other divices that convert heat directly or almost directly to electricity plz tell me.
i might test it in a year or so.

Except using heat to generate electricity takes a lot of heat. I see what you are trying to accomplish but what I want you to know is that the heat of your processor is just going to soar. There won't be enough heat production to the peltier junction to produce enough power to spin the fan at an effective speed and you will end up with nothing but a slight insulator between the processor and the heatsink. You will probably be looking at temperatures in upwards of 75C on idle from the processor before the peltier junction even puts out enough energy to rotate the fan blades.
Furthermore, since the fan won't start spinning until the heat gets excessive enough, there won't end up being a big temperature difference between the two sides of the peltier junction, which will further hinder it's ability to produce power.

Remember the rule: energy in >= energy out

What this means that in a passive collector, if it is perfectly efficient and captures EVERY bit of energy it will have the collected power to counter the power it captured.

So, essentially, expecting the heat provided to be enough to blow all of the heat off is impossible if you remember that you will not be perfectly efficient, you will have a drag coefficient in the fan's bearings, electrical loss in the fan's motor, and air resistance to overcome.

This is essentially the same issue as a perpetual motion device: It is impossible to add energy and not have it dissipate and keep the machine moving. What you need is a cooling system that taps through the subspace field and draws energy from the æther!

i have said that it wasn't a free energy idea it will be powered by the heat of the cpu.

i shall give you some simple math.

if 100 watts move trough the pentlier element (5% efficiency) than we will have 5 watts to spin the fan and 95watts must be dissipated whit the cool block.
the 5watts will be used in the eclectic engine 75 to 95% (depends on the kind of electric motor 95% is AC 3 line) lets say worst case scenario: 75%

25% will turn back to heat. so ~1.1watt. the rest will be used for moving the air. so the cool block must dissipate 96watts of the heat, 3.9watts of the 100watt cpu heat, will be used to spin the fans.

at the end we start whit 100wats and end with 100 watts.

the free energy thing you refer to is a motor that you would spin forever if you apply some start energy once. but i have learned enough physics to know that this impossible. mine idea is different there is an energy source that applies constant energy and that source of energy is the cpu.

you might be right but lets say we start up the fans or the heat pomp whit energy from the out side until the cpu is 60°c and a 30°C deference in temperature so the difference will stay and the fans stay spinning whit the applied energy of the peltier generator. so we need energy to start it but it will running further after the cpu has heated up and the outside source will stop giving energy.

maybe if we do more researches and get the efficiency higher of the peltier generator to lets say 20% would it be possible to let it work. or if we would use heat pomps or so.

The pentlier element is not very efficient, but overall... yeah you can lower the cost to cool the processor. Thermoelectric generators (Peltier) are devices that convert heat energy into electricity and probably the best direction for a project like this.
