affordable and effective immersion cooling fluids available in stores

Hey everyone, I’m starting this thread because I couldn’t find any solid answers after digging around the forum. I live in a pretty underdeveloped country, almost fourth-world status, so getting stuff off eBay or Amazon is a huge hassle. Plus, shipping from abroad is a nightmare with all the duties and bribes driving the prices sky-high. So here’s my question: what liquid coolant can I buy locally that’s reliable for immersion cooling? I’ve searched for transformer oil, and it runs about 7 bucks a liter here. I’m still looking for food-grade mineral oil. As for distilled water, there’s no way I’d risk immersing my ASIC in that. Got any recommendations from those of you who know your stuff? What about ATF? Could coconut oil work (I’m skeptical about its viscosity)? I’d appreciate your thoughts or if there are threads I missed that you could point me to. Thanks a lot! Cheers!

Distilled water in a huge no-no. DI water will attack the copper components in the miners and PSU's.

in theory, it should be possible, as pure water is dielectric. But, as you say, NoNoNo.... mineral oil food grade, but i don't know where i can find it here. there are oils, but vegetal, and quite viscose in my opinion. I would look for liquid silicone, or something like this. There is transformer oil available, but how good is it? i read different opinions about it for immersion cooling, but i am biased about using it. There is repsol dielectric oil available and dialax from shell. but, is there any suggestions for liquid more widely available? or maybe a mix of available components? My main problem is that during the day, the ambient outside temperature, since more than 3 month, does not go under 35 ºC (95ºF), so i have huge problems with my air cooling. My asic for the tryout purpose is an avalon 166pro Thanks for reading me
