Does anyone have the dimensions for the S19j Pro, excluding the PSU and fans? We're setting up an immersion cooling system with multiple tanks and won't be using the fans for operation, plus the PSUs will be kept outside the tanks. I need the bare case dimensions to figure out how many S19j Pros we can fit.
Sorry, but I really think you still need the fans to circulate coolant through the fins. Merely having a pump in the tank will cause most of the coolant to follow the least path of resistance, ie flow around the miner. Unless you have some other way to jet coolant through the fins, you need the fans.
It would be a shame to build your system to size without fans, and then find out you need them.
Fans are useless when immersed in a fluid and will actually impede pumped flow... Considering the OP has not said *what* kind of fluid they are using (I hope to god it's not mineral oil) as long as the fluid is rather thin it's quite possible that positioning the miners vertically would give enough flow through them using convection alone with pumping only needed to circulate the fluid to the heat exchanger.
