I'm looking for a cheap dielectric fluid other than Mineral Oil. $60 for 6 gallons isn't horrid, but cheaper is sometimes better if quality can be maintained. It must be a dielectric liquid. Any suggestions? Thank you.
Flourinert is the traditional fluid for this application. $60 is not just cheap... is REALLY cheap. Or an alternative: Water as shown in some video somewhere I cannot find. Submerged oil has taken the search engines over... long story short, they tried distilled water, the computer stopped working... once dried it came back... and btw, they tried this with a Pentium... not Pentium II or Pentium III or Pentium 4... Pentium original. Just to clarify my intent of this comment is mention it could and has been done but I do NOT! recommend it. Water will short the system as there is no such thing as a perfectly clean computer. Also, many cooling companies sell non-conductive anti-freeze based chemicals for water cooling... But the end result of this all is just use oil... or pay a few thousand for flourinert (if you don't know what it is, google it.)
And water is one of the best solvents. Once pure water is exposed to the world it will pick up chemicals from surfaces and from the air (carbon dioxide, oxides of sulphur and nitrogen, dust) and start conducting. Mineral oil or vegetable oil. Mineral oil should last much longer.
most any oil is dielectric, upto and including motor oil. For electric applications transformer oil is what is generally used in..well transformers, it's hard to source though, although I remember a modder getting a sample batch for free. 6 gallons seems like a lot though, plan on using a fishtank?
Yup I plan on trying the experiment here: http://pugetsystems.com/submerged.php I am not skilled with a dremel or anything like that, so at this point, I can't make my own tank. It just seemed like a fun quirky experiment to try with a computer I was otherwise going to junk with the purchase of a new computer this holiday season. Thank you for your answers.
