Most fluid CONDUCT electricity.

This is a REALLY stupid idea.

 

You are right. This is a strange question.

 

Not sure about the conductivity, but it sure is easily flamable......

Mineral oil, vegetable oil, and straight crude oil is not conductive but I wouldn't use crude for this project obviously. In the end all I need to know is if synthetic has any additives that would conduct electricity. I'm going to call the company today and find out.

My plan as of now is to make a Bar&Shield themed case for my computer. Clear lexan tank, black trim, chrome highlights, some decals etc. and SE-SynthIII oil in the tank. If possible I'm going to round the edges and smooth out the design.

Anyhow I'll post i once it's all done for anyone who cares to look at, since I brought it up on here.

I'm not sure about the Synthetics, butI do know that the mineral based oils are used in wirings systems all the time for cooling. Think about all of the transformers that send electricity to your houses that use oil for cooling effects, or the small capacitor boxes that are tucked in those flourescent lights over your head right now if your in an office/warehouse/garage/etc.Even those capacitors have oil in them. Heck,my Chevy S-10's tranmission has electrical components sticking out of it that lay down into the transmission fluid---Ask me how I know---Tried doing a filter/fluid change without a manual, and the trans pan hit agear shift control module causingthe truck to only move forward in3 & overdrive with no 1st or 2nd gear. Come to think of it, aren't some transmission fluids Synthetic. Don't take my word for it. Do your research first, but I think it should work.

 

You should be able to test any fluid yourself with a multimeter set to ohms, if you get no reading when you insert the probes in the fluid then there is no electrical flow thru the fluid in question.

 

Dude! Crazy idea..I like it! Don't let the Cromags get you down. Party on! Loved the video. Reminds me of times that I've tinkered with thermoelectric coolers on an old junk PC I had. Good luck, but I would stick with the mineral oil. I mean, at least its clear.

multimeter test sounds like the way to go, sounds like a very very cool idea.

 

As has been mentioned transformers and oil cooled welders are submerged in transformer oil and are I.R tested with a 1000v megger test (one part of my job).....though internal cables have to have oil resistant insulation.

 

It is an interesting concept.

Does the oil have enough thermal mass that there is no need to remove waste heat from the oil?

If you made the tank / reservoir smaller to use less oil, at what point does the remaining oil become too hot? In other words, what is the minimum quantity of oil to ensure passive thermal transfer?

It would be an unholy mess to swap video cards though.
