I support many PCs in a factory-type environment with very poor air quality. The air is full of salts and other chemicals that corrode everything and destroy electronics quickly. I am plagued with PC/hardware failure year-round but especially in the humid spring and summer months.
Earlier this year, I decided to remove the air from the environment by submerging a PC in mineral oil. It has been running constantly and flawlessly for 3-4 months now.
Under normal load and a room temp of around 24C, it operates with a CPU temp around 45-50C. Because the enclosure is small, everything in the PC runs at about the same temp. This is a little high but should not be a problem (at least I don't think so).
In the past couple weeks we have seen high summer outside temps of 35+C and the inside temps are not much slower. The PC is still performing fine but the overall temps are significantly higher with everything running 60-65C. While this is technically OK (but not ideal) for a CPU temp, what about everything else. 65C is pretty warm.
I also notice the core/package temps are up in the 70+C.
I am not a trained PC tech as PC support is not my main responsibility and I do not have much experience with temps/cooling. Is this sustainable? And are there any components, besides CPU, that I should be concerned with?
My fix is to radiate the mineral oil out side the enclosure (currently a cereal container) but would like to avoid that if possible.
Any advise would be greatly appreciated.
