I am sort of new to this whole extreme cooling concept as I dont have an OC'd processor to cool, however I do think of better ways to cool PC's. My idea consists of just a peltier (wherever/however you use it), and a small hemi-sphere just enough to cover the heat face of the peltier. Now if you could affix this to the peltier in an airtight fashion, we may gave something. Now if I am right, the only way for heat to transfer in a vaccum is via radiation. If we had the sphere made out of heat absorbant materials, wouldn't that allow the heat to be (slowly) transferred to the outside without allowing it to spread to other components. On top of this we could have this near an outlet of the case and blow the heat out. This would effectivly allow the heat to slowly come off the peltier, so the fans could keep up.

The main goal in cooling is to move heat away from the CPU.

Moving heat "slowly" is not going to be better than moving heat "quickly".

[DJ Switch]

If you understand the logic, heat is also to be controlled. By allowing the heat to SLOWLY radiate outward, the fan has enough time to blow the heat out via a tube. UNtil you understand a concept to the full extent do not comment.

[Since87]

I understand the principles involved fully enough to know that you don't have a clue what you are talking about. Whether I fully understand your faulty concept, has no impact on the fact that your concept is faulty.

I'll comment when and where I feel like it. (At least until a moderater bans me.)

good idea, but pelteirs put out too much heat for this kind of a method

Okey DJswitch, with radiative cooling done correctly(with treated surfaces) it contributes only to 10% of total when doing convection cooling. So cutting away 90% of it, I find it very inefficient. I also noticed that you have 1024MB of RAMBUS memory, I think thats also a bit inefficient.

If you create a vacuum on the hot side of a peltier and power it up one of two things will happen. Either the ceramic of the peltier module will not be able to withstand the pressure of the vacuum and will crack, or the peltier will catch fire from the huge amount of heat, which has nowhere to go. Radiation relies on having essentially a large temperature difference and also on the colour of the material radiating. Peltiers are a) white (the worst colour for radiation) and b) not high-temperature devices (typically they stop working at around 85C hotside temperature). Peltiers require significant active cooling, a radation-based approach is not going to cut it. Slow cooling of components only works when they produce heat slowly; peltiers and CPUs do not produce heat slowly, if you try to remove the heat slowly it will build up at the bottleneck, in your scenario this is the peltier itself.

I maybe wrong but does heat transmission require a media to transfer across?

If so then a vacumm with not conduct heat. Heat is the by-product of excited atoms. The heat may be tranfered for one atom to another. But not across a vacumm.

May be wrong here.

Radiation works across a vacuum, it's the principle behind the sun being able to warm us - space being a vacuum after all. The thing is the sun has a temperature of approximately 6000K at the surface which aids it greatly, a peltier, well, doesn't.

Thanks

Stand corrected.....

I thought that the heat itself is not "tranmitted", the light heats up objects on earth/space that transforms the heat into light?

The light is radiation. So you get radiated transfer of heat from the sun to the earth via the light.

I suppose if the surface of the pelt got up to 6000K you might get a few hundred watts radiating off it steady state. You'd have some problems before you got to that point though.
