Science Fair - Liquid Nitrogen Project

[L.C.]

http://www.hardforum.com/showthread.php?p=...#post1031393252

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.

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

 

 

 

Notes:

Post #4, http://www.overclock.net/cooling-experimen...en-cooling.html

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?

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.

I hear liquid nitrogen tastes good

you can do some cool stuff with liquid notrogen. Me and another guy used to throw small amounts of it at each other using our bear hands to dip into the flask. Shocks anyone watching but if you know how to handle the stuff then its fine

Dry ice is fun too. I read somewhere you can make instant icecream with it D: Edited September 4, 2007 by LiDDiS
