Cerulean is me.

There is a science fair every year at my school (or some place in the state or something). All students in highschool I think are required to participate once at a minimum.
This year I have to do mine (I'm a junior incase you are wondering).

My interest has always been extravagant cooling. So this is what I wanted to compare and contrast; 5 different cooling methods (Fanless, Fanned, Water Cooling, Dry Ice, Liquid Nitrogen). Overclock at increments of 250mhz, starting at 1GHz (except starting at 2GHz or greater for Dry Ice and Liquid Nitrogen). Then record temperature readings, etc.



Sponsored:
Liquid Nitrogen and Containment
Dry Ice
Copper Welding/Taping



Materials at Hand:
1x Water Cooling System
1x+ Fans
1x Harddrive
1x DVD-Drive
1x Mouse
1x Keyboard
1x Monitor



Materials Needed:
1x Copper Pipe (for storing of liquid nitrogen and dry ice)
2x Copper Heatsink (one heatsink to be welded to the copper pipe)
1x Roll of Insulation (rolling around copper pipe to further prevent condensation)
1x Roll of Heat/Electric Tape (taping insulation)
1x Copper CPU Heatspreader (place between CPU and heatsink for protection against potential cracking)
1x Plastic Spray
1x Central Processing Unit (CPU; preferably a good choice for overclocking, regardless of heat generation; maybe a late 90s or early 0s model)
1x Motherboard
1x 400W to 500W Power Supply Unit (PSU)
1x Large, Thick piece of Styrofoam or Computer Case (for motherboard mounting)
1x PCI Video Card (=< $10)
1x Roll of Wiring (start button)
1x Button (start button)
1x Thermal Sensor Device



Software Acquired:
Windows XP Professional



Software Needed:
CPU-Z

Basically, you coat the mobo with silicon sealant. Then use a dialectric grease between the CPU and the socket. You can braxe a copperblock to a coppertube. The tube and block are pressed onto the CPU from above and wrapped in neophrene. Pour in the LN2 and heat that baby up.

Question:
There was also this solvent or material that I picked up a few days ago (shame I didn't write it down) that helped to prevent condensation..something I could dip the heatsink into for a few moments before setting it aside for future use. Anyone know what it / some might be?



Other Mentions:
I am wide open for recommendations, suggestions, additions, etc. Even though it might not be necessary, your name will be written down on my credits listing. I'll try include photos whenever I can and is possible.

Another method you can perhaps compare with: Ionic Cooling

Hmm, Ionic cooling does interest me. However I am a bit tight on funds. D: I'll keep it in mind though.
