It's sorta difficult to measure as well, since the absolute baseline for any cooling performance is highly depended upon ambient temps, but as far as cooling goes, oil cooling is only 2nd to LN2 or Phase...
This is just not true. Oil cooling - immersion in oil bath - is not superior temperature wise to TEC's or to chilled water loops. Oil may equal water cooling temperatures but it has a lot of tradeoffs and would end up costing just as much or more.

The only thing oil cooling has going for it at all is it eliminates the problem of condensation for sub zero cooling by direct die phase, tec or chilled liquid. But in that case the oil is not providing the cooling - it is providing the moisture proofing.

Other than moisture proofing the only other thing oil cooling offers is an exotic look.

Actually it can be an effective radiator. It all depends on just how large a reservoir you are talking about. A 55 gallon rain barrel should work. Anything with a large enough surface area should work. It just has to radiate enough heat for the temperature to find an equilibrium. I am not saying this is an efficient or desirable thing to do, just that it is possible to use an enormous reservoir in this manner (have seen pictures of a guy who used a backyard swimming pool as his reservoir)

but u can use a TEC in a oil bath and not wory about condensation and u can run crazy clocks as long as u have a good rad to cool it down u can trow a TEC on the cpu and gpu and get crazy clocks and not even have to think about condensation or have to worry about preping to fight condensation

There is this thing called a period. It has a use. Its use it to break up thoughts. Use the period please.

Commas and semicolons are cool too, but for now we will take small steps.

It's almost impossible to make a 100% silent pc.
I have looked into this ''100% silent pc'' before and so I can share a little.

A 99% silent pc
1. Use a ''Tech station'' or ''OC bench'' of your choice. The idea is that heat can be naturally dissipated without fan assistance much more easily into the surrounding (vs using a case where a fan is needed to exhaust the hot air)

2. CPU Heatsink: new Danamics LMX performs excellently in a passive fanless mode (http://www.nordichardware.com/Review...&skrivelse=565). It can handle i7 920 at stock frequency at full load (at a cool 75C).
Or use Scythe Orochi as a less expensive and more readily available alternative.

3. Passive Graphic card: something like Sapphire HD 4670 Ultimate 512MB Passive or Gigabyte 9800GT 1GB Silent Cell. Not very powerful but not a too whimpy card either.

4. Ditch all HDDs and use SSDs

5. Fanless PSU: Silverstone Nightjar 450W (use two if necessary)

6. A motherboard without a chipset fan is quite common

7. For DVD-Rom, unfortunately this is no substitute for it. It remains the only component with moving mechanical parts.
