problems cooling your amiga.

Fill an Amiga with cooking oil?! Insane! :crazy: :crazy: :crazy:
-
It might work, but doesn't oil react with plastics and break them down over time? I'm thinking about the plastic in wiring insulation & IC packages.
Also, cooking oil tends to "polymerize" over time - i.e. get gummy. It's a real mess then.
Neat idea though.

Madness.

Yeah, someone did this on hardforum a few years back, then actually cooked up some fries in the same tray he was cooling his rig... LOL

Only mineral oil have solvents (who degrade plastics).

That's true, but it takes medium time to do it (a couple of months). But even in meantime there is a major problem: all vegetable oils have some degree of acidity. So they will corrode exposed metals (like chip pins, nude wires, solder pads, connectors, etc). :pancake:

There's also that old classic, the fried egg. (http://www.phys.ncku.edu.tw/~htsu/humor/fry_egg.html)

Thus one should use Motor oil.
-
And when you change out the oil you can use it to fuels your diesel vehicle.

Motor oil have solvents! You will destroy plastics inside a computer using it.
-
Not all motor oils contain solvents!
In any case, the best possible oil I can think of for this application is Öl Held, from the company Hirschmann GmbH. Of course, this is too expensive, so I'd probably opt to use distilled deionized water.

most of us know about water cooling..
maybe replacing it with oil will be better ( no short )

Short? Do you not understand water is an insulator? The only problem in using water is electrolosys.

@AMC258
yes u are correct. my mistake.

Could someone provide a source for this information? I've always thought that water was a conductor, hence don't use electronics around the bathtub, wet floors, etc.
[EDIT] Ah, I think I understand. Pure water is not a conductor, it's the dissolved metals and minerals in water that make it a conductor. That's why you guys are talking about using distilled water as an insulator. Have I got it now?
-
Yeah, that's it. Water itself doesn't carry any loose electrons as H2O is a stable compound, therefore it doesn't conduct electricity. The problem with water is that it's an excellent solvent of minerals, so very quickly in contact with PCBs etc., it will dissolve some minerals from dirt, surface coatings etc. which will provide loose ions and electrons, and then it'll start conducting. Even a beaker of pure water left open to the air will quickly become impure as it absorbs molecules from the air.

@Daedalus
IIRC I read on slashdot, thats what happened after 15 minutes or so to a computer submerged in pure water (was running fine and then it broke). They also mentioned it being somewhat corrosive.
