What oil should I use for mineral oil PC???

[cryptotooth]

I asked a similar question back in February this year, but have been very busy with college since then; now finally have the time to build my first oil-cooled PC. I've got all my designs drawn up and have some parts here to use. I have a tank, pump, radiator and everything on the way, but now the big question is, what oil should I use???
I don't have access to the transformer oil I thought I did, as it's very expensive, and it has a horrible amber tint to it. I have easy access to baby oil which is very cheap at my local Tesco, and knowing some of the staff, they have agreed to help me get around 5 gallons of it.
Is baby oil the best thing to use? I'm concerned about the lifespan of the machine, as it has to act as a display at college for a few months. I've heard of people using "white mineral oil" but that's expensive and surely isn't much different to anything else I could buy?

I've tested some baby oil and it didn't short out when poured into the power supply and on the motherboard, but will components or tank degrade over time with baby oil?

Has anyone tried building a mineral oil PC? If so, which oil would you recommend? is baby oil OK? any cheaper or better alternatives?

I promised I'd document my experience with building an oil PC as there's little advice out there on what to/not to use, hence why I'm asking here.

there's a few different types of baby oil, some of which don't add much if anything at all. the simpler ones are basically oil and a wee bit of "make this not smell like diesel" stuff

interesting how YOU picked the BAD one to show an example, instead of the GOOD one... what are you, a politician with an agenda? Piers Morgan?

I just clicked on the first one I came to. Personally, I don't care, it ain't my money or stuff. I'm just trying to keep the OP from potentially making an expensive mistake.

But as said earlier....find someone else that has done this with 'baby oil', instead of pure mineral oil.
Maybe it works fine. Maybe it doesn't.

If it does....surely someone else has cheaped out and done this with baby oil. Let's look at his stuff and see what happened.

I found this video, and put a comment asking what type of oil it is, but have no reply yet. He says its been working for a year in the description and that's long enough for me. As for baby oil, I know that some oils have additives in them, and lets face it, pc cooling isn't actually a conventional use for this stuff. I thinik that Tesco's own (not sure if any of you guys have these stores) is the closest to pure mineral oil, and only contains two ingredients. parrafin oil and parfum, which is a vegetable oil and from what I read (and asked my science teacher) should be non-corrosive and non-conductive. It's only £1.50 for a bottle so I'll go and get a load tomorrow and dunk a spare pentium 4 in a tank with it. If it's 100% fine in a month I'll buy more. It's not going to be that costly of a mistake if it goes wrong cause I can fill a spare tank for £10 and it's a p4, they're like vermin in my house.

Sorry if this is getting a little annoying now. I'll go and try some of this tomorrow and let you know how it goes.

Don't worry about the annoying part. If someone wants out, there's always the 'Stop Tracking This Thread' button.
If the oil contains vegetable oil and paraffin, find out first how flammable the oil is. That's also a problem with finding suitable oil for this kind of thing. And for being safe, keep the PSU out of the tank.

found this on a website:
"Johnsons Original Baby Oil is less than 1% flammable mineral oil. Mineral oils contain hydrocarbons, a real danger to the stomach and especially the lungs." I
think the boiling point is 250'C so I don't think we can push it to the point where the blow the roof off with a computer before it shuts down.

"Baby oil is not flammable (very high flashpoint & doesn't easily sustain a flame), however it will burn when exposed to very high heat (such as flames)."
