Hi!,
I know you guys said that you had no experience in cooling those but would you think it is possible to put them in cooling oil? Is there any parts that would not like such treatment.
Might be a silly question but… it may be my best option.
We do not know enough about that to give you much meaningful advice. A quick online search indicated that some oils can corrode some metals, and we’re not really prepared to give you detailed descriptions of the various component finishes. There aren’t any especially exotic parts on the board, so I suspect that you should be okay if you’re using a setup that works with other electronics in general.
How much current are you trying to get out of this thing? If you do give the oil cooling a try, please let us know how it goes.
