I have seen all the other liquid filled, and other extreme dry ice cooling, but I have a few ideas to get feedback on.

I am looking at building a normal watercooled system.
But I want to create a smoked, or mist effect inside my PC.

Would dry cause condensation on normal components?
(Dry ice, with mist being slowly blown into the PC case)

Would the mist help cool passive components?

My other idea was to mount a radiator at the top of my PC, then place dry ice above the radiator.

Would the fall of cold gas be enough to cool a radiator without any fans?

Will dry ice on a radiator cool the water to sub-ambient?

I know that Dry Ice would be a temporary solution, but that is all I want it for.
Basicly I want to get a little extra boost when benchmarking, or showing off the PC at LANs.
The rest of the time it would run as a normal watercooled PC.

/Edit:

A few more questions:
Is there any other ways to prevent condensation besides heavy insulation?
Are there any chemicals or materials that can help prevent condensation?
(For example how does a anti-fog mirror work?)
