| 287940 | 2004-11-04 11:00:00 | Well, I was thinking of some sleep, then perhaps some school, then some fireworks. Then I'll get round to it, I promise. If my discman (electronically) works under oil I will test it with a motherboard. George |

| 287941 | 2004-11-04 11:03:00 | I would say about tea time tomorow when George's mum is trying to cook some food he will be doing some fast talking to explain the complete absence of cooking oil,though i'm sure she will understand when he explains he had to fill a container with it and submerge his discman.....to see if it killed it or not....... | metla (154) | ||
| 287942 | 2004-11-04 18:18:00 | Theoritcally you wouldn't need the fans to spin anyway? Because the cooking oil would be cool. So say you kept it at a cool temperature the need for fans is out the door. | MrBeef (342) | ||
| 287943 | 2004-11-04 18:24:00 | Mmmmmmmm.............wonder what he did with the fish ?:| The oil would slow them down a little. There is nothing intrinsically wrong with oil cooling for electrical & electronic equipment, but cooking oil is not usually used, and submersion is not common practice for electronic circuit boards. The fans will be overloaded because that won't be able to spin freely, and better results might be obtained by removing them completely and allowing thermal circulation to do the job. Otherwise install a slow speed stirring paddle. The biggest issue will be the ability of the oil to dissolve various substances on the board. Over time, paint and some plastics may be dissolved, especially in areas that get warm. Plug-in devices such as the CPU and video card will also be affected and of course all interconnecting plugs will have their contact area contaminated over time. On the positive side, it will probably last as long as the average experimenter's computer, anything from a few weeks to 4-6 months before it has to be junked. Special mineral oil as used for electrical cooling and insulation might be better in some respects but would cost more and might even be worse in the long run. It is a do it then dump it exercise I guess., But don't dump the oil down a drain! Cheers Billy 8-{) |

| 287945 | 2004-11-04 23:17:00 | George, I have done a bit of research on this and you will need some sort of oil with a noncorrosive element, ie anti-oxident properties. I would suggest you go to your local deli and get about 20 litres of extra virgin olive oil. Now you don't want those ones that are advertised on TV, you will need the absolute best quality, no additives, squeezed between the knees of Italian Peasant Virgins (extra Virgin). Just tell the person what you want it for and they will make sure that you get the good oil. I see you are from Wellington so maybe Moore Wilson would be able to help or certainly Dixon St Delicatessen. Look forward to the results. |

| 287946 | 2004-11-04 23:25:00 | At a trade show in Sydney many years ago, I recall seeing a tape deck (open reel) and an oscilloscope both doing their thing while submerged in a glass tank of freon. Smelled good too, even if it mainly served only to give a bit of unforseen zest to future sunbathing. | R2x1 (4628) | ||
| 287947 | 2004-11-04 23:26:00 | Does oil freeze? If it doesnt you could submerge your PC in oil then place it in the freezer. No need for fans when the ambient temps below 0 ;) | Pete O'Neil (250) | ||
| 287948 | 2004-11-05 00:17:00 | It would certainly work, at least for a while. I wouldn't trust any cooking oil to be acid-free. Best would be proper transformer oil. You don't need fans. The vastly improved heat transfer and convection will cool the parts aslong as the outside surface is large enough to keep the temperature reasonable (by radiation/transfer to outside air).You could blow air onto the outside of the box. But it's messy. Why not just a properly designed air system? You're only talking about a few hundred watts maximum. Air cooling is still used for kilowatts and hundreds of kilowatts of RF transmitters. That's because it works, and it doesn't leak. |
