Frequently Asked Questions
Can the A1566i run without immersion cooling?
The immersion variant is designed specifically for submersion in dielectric coolant. Running it air-cooled may result in thermal throttling or damage.
Is immersion cooling practical for home miners?
Not typically. Immersion cooling requires specialized tanks, coolant, and heat exchangers that are practical mainly for commercial operations.
