What a min, wtf? You dont want to use AF because:

???

How many times are you going to need to throw away AF? Keep it in a milk jug and wait a whole month.

distilled + AF + iodine. I dont see how it can get cheaper and easier than that?

Let's step back for a moment.

There are two kinds of antifreeze, Propylene Glycol and Ethylene Glycol.

Ethylene Glycol is toxic but has no nasty chemical taste, so dogs have been known to drink it out of antifreeze-spiked puddles and get sick. It's bad for rivers, streams, lakes. It may reduce algae slightly in a WC system but only because it's toxic, not because it's antifreeze.

Propylene Glycol is non-toxic and recognized as safe for use as a food additive by the FDA. Propylene glycol makes fake fog at theatrical/concert performances. While I wouldn't want to actually drink the antifreeze-packaged version of propylene glycol, it likely wouldn't even make you very sick. It won't reduce algae in a WC system because it isn't toxic to the algae.

It seems clear that the only generally-available chemical that is proven to reduce algae in water circulation systems, AND is proven to not harm pumps, is anti-algae solution for use in fountains and other commercial water features.

Or just run pure distilled water and plan on swapping it more often. You can get it VERY cheap - under a buck a gallon. No mixed metals so no corrosive issues. If you see a new civilization growing in the tubes, just flush it, clean it, and THEN get some killer stuff.

Sounded like the cheapest solution yet so I went with that. Though, I am also conducing an experiment on my 5% baking soda and 95% distilled water idea.

I have two small plastic containers each with 250 ml of distilled water, a copper penny and a very small amount of dish soap. One also has a table spoon (~1/2 fl. oz) of baking soda. I will be monitoring them for two weeks to track any degradation of the copper penny or any other reactions.


I completed my water cooling setup yesterday.

(I have an AMDXP 2600, overclocked form 11.5x166 to 10x200. Ambient is 25C. All non-ambient temperatures are as reported by CPU sensor. I realise it is HIGHLY inaccurate and inconsistent but it is all I have.)
I had been idleing at 48C-50C now I am idleing at 30C-31C.
At full load, as made by a 100% CPU utilazation and normal length S&M FPU test, I went from ~70C to 34C!

(Now at 11x200 with ambient at ~27C.)
~34C idle and ~37C prime95 full load blend test. (Working on S&M test now.)

I am very pleased with the effectiveness of my water cooling.

All told I spent about $95 including all parts, tubing, fittings, shipping, gas, and taxes.


Now I have two questions:

[question 1]Assuming I had the correct mounting hardware would the stepped MCW6002 work with socket 478, 757, 939, and 940 CPUs?

[question 2]Would there likely be any appreciable cooling disadvantages?
