I have 4 pcs mining rigs. Each of them has 12 GPUs RX570 4GB.
Total 48 GPU. I want to use air conditioner for cooling.
What should I do ? is it safe to use air conditioner ?

cold air and hot air in the same room is a problem ?
I dont care about the profitibality I just want to know is there any problem if i use air conditioner ?
The cold air dircetly to the rigs or somewhere else direction ?

if there is anyone use air conditioner, please help me. I want to be set up a proffessional system.
7kw air conditioner is enough ?

most of us like to vent the hot air out of the room.


7kw air conditioner is not what I need to know

how many btu does it do?

you have 48 card that can pull 150 watts each that is 7200 watts 1 watt of heat is about 4 btu

so you produce about 28,000 to 30,000 btu.

you ac would need to cool more then 35,000 btu.


I would also like to mention you won't be able to use your 48 cards past nov or dec of this year. They won't work on eth or other algos.

it will help you to understand all those cards will become useless for mining very soon.

24000BTU air conditioner.
4200W power for 48 GPU+ mobo.
The room seems cool. No any heat problem so far. I feel cold air in the room.

But i fear if any type of hardware failure hot air and cold air in the same room.
I dont want to use ventilation system. I want to use AC.
Should i send the cold air directly to the rigs ?
i use wall mounted split AC.

It's not necessary to point the cold air direct to GPUs, but there's no specific problem of doing this if you want
It's better if you study the air flow of your room with your rigs and make the best choice with your air conditioner

The only problem to GPUs and board in general is to blow cold air if the board is too hot, but it's for long time, can do some micro ruptures on solder, but I don't see this problem in your room and rigs
So make some tests and watch the temps, no problem

Do not believe the watts the miner reports, that is the power load of the core only, gpu whole is 130 watts or more and x 48 = 6240 watts, each watt is = 3.4 btu, so 3.4 x 6240 = 21200 btu, so 24k btu seems okay even though you think your 48 gpus use 4200 watts ehhe

24k ac consumes around 2200 watts. Not worth unless each card earns 5 usd per day ehhe, but if you want to keep it clean, tidy and cool, that is the way. 33% more electricity spent, a good exhaust will consume around 150 watts, 10 times less.

Where I live it can get really hot during the summers and in my experience, AC doesn't do much for the rigs. What you need is a good exhaust to vent out the hot air outside.

nowadays it is not practical to mine cryptos and using aircondition, I've been a miner since 2015 and mining in a tropical country, in my experience a good ventilation is enough to cool down your gpu's. If you are living in place that has good temperature, no need to use an AC, and by the way if you are using AC it will give a not good outcome with your rigs, because if you are not doing some good config in your AC system, it will cause static in your machine.

I dont mine ETH. So, the power consumption is low. 48 GPUs eats only 4200W
The income isnt important. This is my hobby. I want to see everything well running, clean and tidy.

The AC system is the inverter one. The power consumption is 400W-2200W. It changes all the time.
Static will be problem ? or any other problem ?

My rigs are running on the same room with the AC for a few days. There is no any problem so far.
The AC doesnt blow the air to the rigs directly. The room is enough cold.
I set autofan option in HiveOS. The temparatures of the GPUs are 59c-66c.
I dont want GPUs are so cold. 59c-66c is enough for me. In this way, the AC system eats lower WATT.
The important thing is the GPUs has no dust, no overheating.

when people are mining with air conditioned rigs. you sell your coins and RUN!  :D

Even if you are mining to get some coin - whatever it is. You can always mine ethereum - get more cash this way and then convert it to whatever coin you want to have/keep.

If air condition does not blow directly into rig then it is ok.
Also GPU can easily run at 75*C. The Max temperature for most GPUs is 90*C and this is too much usually.
Also fans in GPU should not run on 100% so if they are running at 60% then you are all set :)

I had air conditioner that wat takin 5kW and cooling with power of 15kW.
Rigs that were in that room were taking about 25kW, so air conditioning was cooling but had not enough power. Room temperature was 30*C.
They were running or a 2 years in that conditions and they have totally no problem and running even now almost 3 years. GTX 1070 8GB.

It looked like this: https://youtu.be/F9_2WBalUF8

And you are right, it is clean and without dust.
Currently i have air cooled GPU farm and the dust is there :)
Actually dust is not bad, the worse are those flying worms which always get somehow in :)

When I saw the topic title at first I was afraid that Bitmain introduced some new device which is mining-enabled (like their LTC-mining router)  ;D

When air conditioning you should also watch out on the humidity of the room. That's something different than regular air flow generators.

You have really good set up :)

1- Your total power 25kw at the wall ?
2- Your AC has 15kw cooling capacity and eats 5kw ?
3- I see you have pipes on the ceiling. do they blow cold air from AC or is it for exaust fan for the hot air ?

I live in a really hot region with %70 humidity in summer seasons.
The dust is a big problem for me. Fan of the GPUs fails after everal months. And yes ! I sometimes see some flying worms in the rigs area.
I cannot stay in the rigs area when the rigs has any problem. So, i decided to use AC.
I dont think about AC price and its eating power because we can use the electricity bill for taxes.
Mining is my hobby. I dont need the profit from it. Of course, i get money but i always tries to mine different coins in different algos.
I want my stuff clean without dust and working in good conditions.

That is the thing people dont understand, with temps around 40c or more, during summer or in tropical places, air conditioner does not work unless is totally sealed off and it does double than 3.6 btu per watt. The ambient air will make ac useless if otherwise.


Exactly, but we are not quite there yet hehe, crypto has to rise a lot yet, remember the $20 per card per day? hehe, this week, crypto reached $1 per card per day again, so there is a lot to go before that.

the trick or the gamble here is if you keep the coins of that 1$ a day per card mining and sold that coins at 20$ a day per card mining, works like you also mined a 20$ per card back then too.


that scenario will send some mining devs in heaven limbo just like claymore and wolf hehe

we were never at $20 per card lol what are u talking about, maybe $20 per rig you meant.  Im not talking about mining eth back in 2016 and holding to resell for a profit of $20 plus or more per card.  I don’t remember a sustained $20 output per card for daily ming profits

Vega on monero was around 20 usd per card and gtx 1080 on dgb was crazy too, around 15 usd. Polaris got as high as 10 usd per card on peak, january 2018.

I got into mining when it was LESS profitable than it is now, waaaaay back in 2016, and even then It boggled my mind how much I was earning. I told everyone I knew to get it, alas almost noone listened.

2 pcs 24000BTU air conditioners set to 23c and maximum fan speed.
Both of them eats total 3400W power thanks to inverter technology.

26 pcs  RX570 4GB + 96 pcs P106 6GB
11 pcs rigs work well.
The rigs cleaned from dust. There is so small dusts now but it is no problem.

There is no high temp problem although i live in a really hot place.
I like my new system so much.

Using AC for in the mining room is OK .  i have setup some humidity and temperature monitors which triggers notifications via mail and i can go and fix the issue .Just make sure the AC setup is suitable for your need.

Is very much okay, just make sure the cool air is dry air and no problems at all. The good thing is almost dust free, the bad thing is cost, I mean, a very good exhaust fan uses 150 watts, the ac that resembles the exhaust fan in efficiency uses 3000 watts, that is 20 times more. Pro miners would use those 2850 watts to add more mining rigs ehhe.

Generally you shouldn't point an air conditioner DIRECTLY on exposed computer parts which is basically what most open air mining rigs are. Reason why is because depending on the humidity some of the water vapors can go on your GPUs and damage them.

However will this be an issue? As long as they are running the water would evaporate almost instantely and not cause damage. However if the rigs crash one day and GPUs are cold and you got a AC pointed at it, you might find it completely wet one day.

This thread however brings back memories. Back in the Litecointalk days, there was a fellow that had so many GPUs that he actually had to use an air conditioner to cool his place..... in the winter.  Crazy times.

Almost dust free wit air conditioner. I like dust free option. Everything works well.
Nothing wet so far. I point the cold air to the ground.

I have no any idea for winter times.
But i need air conditioner for summer times.
it s too hot till October in my place.
I wanna keep using air conditioner in winter. The outside temp in winter is around 15c - 20c here.

I will send some photos for you people.

In general, this is a pretty funny topic, no, seriously. Air conditioning mining is ingenious. Although what I'm surprised, I often began to hear something someone started to mine on Game Boy or on the first pc from Apple. I won't be surprised if tomorrow I find out that some enthusiast has started mining on smartwatches. And with regards to the air conditioner, you just reminded me of my problem. I have small children at home, and they often spill something on him and this is a quiet horror. I'm already so tired of calling these guys airconservicingsingapore.com (https://www.airconservicingsingapore.com/chemical-overhaul/) , I think they already consider me as their employee. The air conditioner should be moved away from children.

So far i found air conditioner best cooling system, my place is very hot in summer 45-50C outside and very dusty. Here vents dont help much when temperature gets above 40C. Luckily my electricity is very cheap thats why air conditioner works best for me

Consider air conditioner if you have free electricity, they are the best for cooling and don't listen to other ideas about well ventilation or some fan modding, air conditioning works best

You should choose an air conditioner or several air conditioners depending on the amount of heat that your mining farms give off.
If your mining farms consume 3 kilowatts per hour, the air conditioner will consume 0.8-1 kilowatts per hour.
I don't know what aircorn is, but the calculation principle is basically the same.

dont use air conditioner for mining, you only burning electric for 1-2c cooler for 600watt full ac

better using in&out fan/exhaust consume only 50w both of them....

I had the experience of using 35 RX570 video cards and analogs in a 30 square meter room without air conditioning.
Several holes in the wall measuring 10x12 centimeters were used for ventilation.
For 3 years, more than one video card did not break, although in the summer it was very hot in the room.
The summer temperature rose above 35 degrees for several weeks. This summer was very hot

I use a commercial AC to cool down my 42 GPUs and since march everything has been perfect!

To be more specific it's the Mitsubishi 24,000 BTU Wall Mounted Air Conditioner Air Handler
Model: PKA-A24KA7.TH

I am planning to add more GPUs so that way I am sure the temperature and humidity are controlled plus it works during winter, the outdoor unit can do up until -40°C.

It cost me 7,358.40 CAD and I have professional technicians I can contact quickly if something wrong happened.

What will damage your GPUs the most is the heat, I am planning to keep healthy my GPUs for years to come and I don't have to bother anymore with a ventilation system which you have to constantly adjust manually based on the outside temperature.

It's been amazing up until now but for someone with high electricity cost it might not be financially wise. Here in Québec I pay 0,10$ per kWh which is pretty low and our electricity comes from a green and renewable source.

But why?  I live south of you in much warmer part and run hundreds of gpus even in the heat of August when it can get to 110F and no issue with over heating on just ambient air temps.  And before you say it hurts the gear.  A lot of my gear is now 5 years old and still running.  Out of over 300+ gpus ive lost a total of 4 units in all these years.  I think either you dont know how to set up the gear or you are imagining probelms that dont exist (or you have terrible air exchange with the outside).  Either way i pay about 1/2 the power cost you do and have a lot more profit because none is wasted on AC.  My power is all hydro. 

Do as you please but there is no need for AC. 

False

What most kill GPU are the moist.

Never use AC units if you want your GPU last years.

I have 56 GPU in a a room at 34C all year since 2017 (somethimes the room get at 40C) and all perfect, so far 2 MSI armor and 1 Powercolor fail but thats a problem with the heatsink (in this models they dont touch the memory, only the GPU) i fix then reballing the memory that fail.

Just put all the cards on a "Hot Room" and "Cold Room" and you will fine.

Miner container is the best example.

AC removes moist, it dehumidifies the air.

also 24,000 btu is enough if you are in a cold climate but if you are in a hot climate you'll need x2 to x3 of that 24,000 btu.

My Mitsubishi commercial AC also has the benefits of a variable speed inverter scroll compression which means:

Conventional compressors typically only run at one speed and can only cycle
between on and off – not an effective method for delivering cooling in a
server room. The P-Series is equipped with Mitsubishi Electric’s quality-made,
durable variable speed inverter scroll compressor that can adjust its speed to
provide precise cooling as needed. This means:
• a consistent, precise temperature is maintained at all times;
• increased energy efficiencies, resulting in cost savings;
• when a server room expands, the P-Series can adapt to the increasing heat
load without requiring the installation of additional equipment.

My AC cost me around 3,50 CAD per day (2% of my average daily revenue) for continuous sensible heat load of my minage room. I will soon add more GPUs and will capitalize even more on my AC daily cost even though I spent many hours to set my node validator on RocketPool for the upcoming ETH merge.

the data sheet you posted stated it is twin rotary and not scroll compression.

a non inverter will be having the same performance as an inverter at maxed out capacity.

the only good thing about an inverter is this because it is better in adjusting than a typical thermostat which is an on-off switch.

but i'll have a different strategy if i were you, i'll use a non inverter windows type 12,000 btu for the first 50% setup of the rigs, as the mining expands i'll add another 12,000 btu. the benefits are..
- non inverter AC are cheaper.
- if an AC has a problem you can run your farm at 50% (backup model)
- window type are just square boxes, 12000 btu AC is still small enough for a single person to remove and install, so if you are a one man army like me, you can DIY (change capacitor, clean, install etc.), no need to call anybody and waste time. non inverter AC are lighter than inverter AC BTW.

have a spare AC so you can continue mining while an AC is in maintenance.  

have an air filter sheet that you can place over the evaporator intake, this will reduce your maintenance times for cleaning the evaporator.

You need buy a dehumidifier if you want remove the moist, not a AC conditioner. See how DATACENTERS remove the moist.

https://www.cielowigle.com/blog/dehumidifier-vs-air-conditioner/

if you want to dehumidify without air conditioning, dehumidifier will work but if you have an air conditioning then you don't need a dehumidifier., what you need to buy is a humidity measurement tool so you can decide if you need both or an AC is enough, chances are AC is enough.

the water dripping from the AC unit..that's water being removed from the air.

Philipma1957 I believe that more new coins are coming into crypto as we speak so they will have less DAG requirements? What about Ethereum Classic mining algorithm? When it was upgraded even 3gb GPUs can mine them, rx580s are 4gb I'm sure they will have some usefulness

I don't like using AC in my farm because they consume more power than my mining rig, not good if you don't have extremely cheap power solutions it's better to buy two exhaust fans, they are different in size depending on how big your farm is

The problem may be that air conditioning cannot be installed in some rooms, while ventilation cannot be installed in others.
For example, if I put the air conditioner in my garage and leave it on at night, then the thieves will guess that there is a mining farm there.
Such moments should always be kept in mind.

Same with ventilation lol.

Security is another section/chapter/topic in mining.

And I have natural ventilation, but I always try to do so that there is no unnecessary noise.
This situation is highly dependent on your neighbors and the crime in your area.
If there are more than 100 video cards in the room, then many miners prefer to use security.

Is cold air from your AC safe for your desktop pc?  Yes, it's absolutely safe to have cold/hot air in the same room.

General rule of thumb is that your AC unit should be at least as many watts as your rigs.  So if you're doing Eth with those 570s, that's roughly 80w x 48 = 3840w.  Add in some overhead for the CPUs, and make certain that your cooling is redundant because at some point one of your AC units will go down.

That is interesting, I have never heard of that, as far as I know, 1 watt = 3.4 btu, so if your ac is 12.000 btu then you could cool down up to 3529 watts. Anyway, I'm not against using ac, people need to calculate if is worth and this topic comes up a lot when profit is very high. When profit is low or negative nobody talks about ac ehhe because there can't be any margin of error and if there is then you are screwed --> out of business hehe

this is a really good setup, natural ventilation = lots and lots of space

real estate is far more expensive than AC'ing your rigs, but if you have those already or renting it for cheap..then you win.


12,000 btu cools 3529 watts if nature favors you, if not then that 12,000 btu might just cool down around half of that (rule of thumb of the other guy). the (+/-) ~40-50% margin of that is huge. climate has a huge role.

I saw before miner strip down ac and build cooling directly to gpu heatsink, and it successfully turning down lot of heat in modified cooler, this most effective way using ac for mining compared standar cooling down the room, which is worst for miner only down 1-2c for massive wattage

Yes ambient temperature plays a big role here, for example I have ac in my room and that is a 12000 btu, when is at 40 degress celsius, that 12000 is close to nothing because little by little that 40c degrees air comes inside, my room is not totally insulated, so ambient temperature will always come inside little by little and when the temperature ambient is at 24c then I can even leave my window opened hehe, if you plan ac then you need to totally insulate that room but still as the ambient temperature rises, less efficient will the ac be.

I don't use AC for cooling I have friends who use AC and this doesn't stop the rig from mining it's just that I prefer using old cooling method which is getting the heats out of the farm or room with breeze, before building a rig make sure you find where easy breeze pass through in your home
