I have a computer outside its case. All the components are attached and working properly, the problem is that fans dont seem to do a good enough cooling when demanding programs such as high end games are run, so the fans go crazy sometimes and the room with the computer gets increasingly warm especially with the door closed. I cant afford a commercial liquid cooling system so I thought I'd try to build my own.
So my plan is to buy these things:
A small refrigerator. A plastic box big enough to hold the motherboard and the components attached to it. Enough oil to will the plastic box almost full.
So I'm going to submerge the computer in some form of oil. I'm not sure which kind yet. Since oil is better at absorbing heat than air is, while preventing freezing and water vapour on the electrical components it should be the perfect solution to keep the computer cool and running smoothly. Even if I overclock it as much as I can.
The only two components that need to sit outside the fridge is the cd-rom and the HDD. I'm not sure the cd-rom station is even necessary since the oil computer is going to be on the same network as my main computer so I can just transfer any files or share the cd station in my home network. But the hard drive being the only mechanically moving part might not fare too well in oil so I'll leave it dry on the outside of the fridge.
I'll bore a small hole somewhere in the fridge from where all the cords can come in/out.
Questions: What kind of oil should I use? I saw a video where they used mineral oil, but thats probably too expensive and they thought vegetible oil would go ranchid (which it doesnt even after years in room temperature.) Do you have any tips I should keep in mind to avoid destroying my computer as much as possible?
