hire a engineer to build me cooling system like a fridge/freezer

[bliblz69]

I am plan on getting a professional to design me cooling system for my 2 KD5'S has anyone design or  made a cooling system like a fridge/freezer like system that works and remove's the condensation problem.

Does anyone know what is the maximum temp ratio these run at or has anyone figured out how low they can put the temp without running into Condensation problems ? Does anyone know of any company that would give out design plans or make one for me ? For just 2 miners I want to see what is the maximum hash rate these KD5'S can perform at when overclocking them.

1. Goldshell KD5
2. qty 2
3.  Max 3 - 45°C the machines vary from 65°C - 80°C with exhaust fan 99°C without
4. Phase 1 240v 50hz

i have 8.5 kw solar system.

I do plan on getting more miners in the  future.
Though just need help with my first two so the chips don't break in the long run.

or is  immersion cooling the only way to go with cooling miners down? What is maximum temp you can reach with immersion cooling ?

I have seen  some vids the machines only drop from 80°C - 70°C then 40°C I guess that is ideal but I want to do more to see what is the maximum it can do without breaking the machine of course.

Kd5 mines what coin?

btc good

any other coin this belongs in altcoin section.


Now pretend it mines btc.

what is the watts?


okay looked it up 🆙 it uses 2250 watts so lets pretend you are asking about the s17 which uses same watts.

two units use 4500 watts.  and that is about 21000 btus of heat.

If you are doing two units I would figure you need to feed 1100cfm in and 1100cfm out.

do you want to feed it cold air you can from an ac like this. wait for link

outside > air ac > box with two miner > vent outside

so above is costly due to power user for the ac

it will not have condensation issues.

it will cost power an ac will burn $$

the refrigerator idea is worse

has anyone figured out how low they can put the temp without running into Condensation problems

Condensation is not the problem. The problem is that the chips NEED to run fairly warm and yes, even what most would call hot. These days all miners have a pre-heat cycle for good reason -- being power devices the designers knew they will get HOT so the circuits have been designed to accommodate changes in bias that happen when electronics warms up. As a result, they don't run as fast when cold and some will even refuse to start.

Liquid cooling. I had a post about it that was deleted. Look up Mineral oil for cooler of electronic components.

Side hack. It does not lead electricity very well. If people don't like your idea then keep on busting it. You put your Antminer in an aquarium for test. Mineral oil.

Bet it's gonna be a mess. Use an outdated machine.

Remind you income is pretty high on the KD5'S. At writing time. $162.30/day. Per machine. Manufacturer estimate.

As has been pointed out countless times in other immersion cooling threads - and there are a LOT of them here if folks just take a little time to look -- mineral oil is a horrible fluid to plunk electronics in for prolonged time. It attacks PVC wiring and anything nylon or rubber by making them very hard and brittle. The sulfur content in it attacks copper as well.

There's a reason that there are commercially available alternatives to it - silicon-based oils and other purpose-designed dielectric thermal transfer fluids do not attack metal, plastic, or electrical components.

Refridgerator idea is shit, go with air cooling or immersion cooling.

[spectre71]

5500 watts equals approx 18.767 BTU's. Typical 24,000 BTU window unit would work or mini split system ideally. But the cost of the split system is conserable

he is better off with a wall ac set up correctly much cheaper

he then needs some venting out of the room.

two of these.

ac into room >>>>>air flow>>>> two miners using ebay vents >>>air flow >>> window

I would consider liquid cooling.

Not immersion, but heat-sinks screwed to aluminum plates to which there is aluminum tubing brazed on the opposite side.

The cooling medium should be distilled water.

With pumps moving water through the tubing attached to the heat-sinks you can use a small fan-cooled radiator adjacent to the PC. Or, provide a small refrigeration unit and a thermostatically-controlled re-circulation valve to control the temperature at the heat-sinks.

This is how electronic equipment is cooled on navy ships, etc. where computers, radar, etc must be kept clean and dry in an equipment enclosure onboard ship.

This would have the benefit of avoiding dust-laden air being blown across your computer's electronics.
