Hello, I am currently engaged in an High School chemistry project. I was wondering if you guys could help me out. The project itself is not required to be related to chemistry at all; it can be a physics/biology project as well. After some brainstorming, I have narrowed my topic down to CPU cooling. I plan on researching water cooling and doing my project on the different coolants and the proportions of the actual coolants' chemicals to hopefully come up with a valid conclusion. For those of you who aren't familiar with water cooling, it's basically a bunch of tubes inside of your computer that are filled with a coolant. This coolant is what runs across the surface of the CPU and dissipates heat through a radiator. So far, all of the research has led me to the conclusion that the study of this 'heat transfer' is basically centered on thermodynamics. I, however, have absolutely no idea what some of this physics jargon means. I am in the middle of teaching myself some of it from the basics, but was wondering if some of my questions could be answered here. One of my questions relates to the actual testing process. I have 5 old pentium 2 300 mhz computers. I am trying to figure out the most efficient/effective way to do the testing. I plan on tesing each of the coolants on each of the (identical) computers twice, yielding 10 data points for each different variable. The computers will be running for 1 hour, and data (regarding CPU temperature) will be collected at the 0,5,10,30,and 60 minute marks. With the cleaning and setup involved, each different coolant will take 3+ hours to test (2 hours testing = 10 data, 1 hour cleaning, setting up). Does this seem viable? My next question; is there any linear relationship between chemicals that demonstates the heat dissipation properties? I am trying to think of how I will be able to calculate/predict how much heat is going to be dissipated if I change the mixture (ie water + bleach) and/or proportions. I have looked over some thermodynamics literature, and here is a summary of the information that I have gathered; Well there you go! I'm a physicist! Haha thank you for any and all of your help! I am aware of the danger involved with the CPUs overheating; if I run the water cooling pump for a few minutes before I turn the comp on, it will be fine. Thank You!!!
