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 Notes: Post #4, http://www.overclock.net/cooling-experiments/136098-liquid-nitrogen-cooling.html http://www.crazypc.com/articles/condensation.htm http://www.xtremesystems.org/forums/showthread.php?p=2404473 http://www16.big.or.jp/~bunnywk/ln2/ln2_e.html http://www.tomshardware.com/2003/12/30/5_ghz_project/ http://www.overclockers.com/tips422/ http://www.theinquirer.net/?article=30925 http://www.tomshardware.com/2003/12/30/5_ghz_project/page2.html http://www.madshrimps.be/?action=getarticle&number=4&artpage=1768&articID=429 http://www.beowulf.org/archive/2001-June/003919.html http://www.abc.net.au/science/surfingscientist/behind.htm http://www.xtremesystems.org/forums/showthread.php?t=125155 http://www.xtremesystems.org/forums/showthread.php?t=102575 http://www.techwarelabs.com/articles/mod/condensation_prevention/index_4.shtml http://www.xtremesystems.org/forums/showthread.php?t=125155 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.
