I hope now everything is clear. Still need answer about my Clearco ST 50 oil as a coolant.
Thanks,
If you mean ST 50's compatibility with electronic components, so far I've seen zero issues.
As I posted in the original immersion cooling thread we have high voltage power supplies putting out over 10's of kw waste heat each that use it. Components in those range from epoxy encased diodes, various wiring with PVC (most common general wiring used everywhere), polyethylene, and silicon jacket wiring, nylon connectors, transformer varnish and potting epoxy, silicon rubber seals on electrolytic capacitors. Zero changes in their properties seen after so far >60k hrs on the oldest individual systems.
What I would be careful of is silicon rubber glue or sealant aka RTV joints - That tends to gel then crumble so use other ways to seal and bond things.
Based on that *if* I was to go with liquid cooling for a large installation I would definitely use the Clearco fluids. Again, because at least the ST50 is proven to not harm components/wiring, is water thin for easy pumping and great flow properties, has great thermal transfer specs and very high ignition point. Also, while certainly not cheap it costs about 1/10th what Novec costs and more important to me does not evaporate/require a vapor-tight system. Ja if there is a leak you have to contain/clean it up whereas even at a moderate 75F or more Novec will quickly go away on its own but there is also a chance to capture the fluid and filter/re-use it.
Have I yet put any of my farm in it? No. Why is because I am at my power available limit and normal ventilation works fine.
Do be aware that as an industrial fluid it is NOT sold to private individuals. Clearco and their distributors will only sell to registered companies.
