New to Mining - planning on S9 and Mineral Oil Bath

[curto]

Guys,

Have a couple of S9s on the way - plan on putting them in a mineral oil bath and then trying to harness the waste heat to heat our hot water for the house through a heat exchanger.

I plan on using BraiinsOS (paid version).

My plan on the oil bath is to us a gear pump to move the oil around - inject it into the "in" side of the miners and suck out the hot oil from the top of the tank - my question is

Is there an advantage to leaving the fans on and have them running slowly to move the oil through the units - or am i better off just removing them entirely.

My goal is to run the Oil bath at around 50c or so

Since you have pump to move the mineral oil it's fine with or without fans.

I believe that leaving it there would help a little bit to cool down your miner but it consumes power. So it depends on you if you want efficiency.
I don't know if you could run it at 50c but as Bitmain normal ranges it should around 65c to 115c since you are using Braiins and not their stock firmware it would be fine.

Most fans aren't designed to run in mineral oil.
Buy a couple of fan simulators.

You will need a pump to handle the oil flow, these fans won't do any good when put under oil, and will eventually if not instantly die, you either get some fan simulators or use custom firmware that allows you to disable the fan check phase altogether.

Thanks guys for all the replies.

As i will be using Braiins OS it does allow me to disable the fan check so i will just leave the fans in place at this stage.

The Pump is plan on using a Mallory 5250 Gerotor pump - it will move 250 US Gallons per hour - as it is a 12v DC pump i will be able to control the speed of the pump to keep the oil at the optimum temperature for the rigs.
