Electric conductivity of oil?

[Makhaira]

Plenty of attempts have been done using a variety of oils. From memory, the main issues are:

1) You need to seal around the chip area to prevent shorts
2) Some oil conducts
3) Some oils are corrosive
4) All oils will make an almighty mess when your case leaks.
5) Other than total silence (achievable with a large passive WC setup), there are no real benefits over WC.

Not so much the oil temperature but just heat, oil is really only exceptionally hot around the piston crown, skirt and bore, oil is cooler in the head for example but a lot of heat is generated there in itself.

Electronics can cope with several hundred degrees, they just need to be industrially insulated.

Sorry to drag this up again, but no they can't, at least not the kind of devices you find on a motherboard. Industrial rated silicon based ICs are typically rated -40C to 125C, to get significantly higher requires some pretty exotic packaging. High temperatures also significantly reduces bandwidth and increases leakage currents, so you are likely to see operational problems well before the actual chip is damaged in ultra small feature size devices like modern CPUs.

Vegetable oil is a much better idea OP..

Used engine oil is an absolute NO no. way too much carbon particles in it, not to mention how corrosive it is!

Not to mention the solder which would liquify and make the components drop off the board!
