What is Air Cooling?
This method of cooling is exactly as the name implies. In order to control the temperature of mining equipment, ventilation fans and ambient air are used. Increased airflow over the mining rig in this area helps to dissipate heat. Although most mining rigs come with inbuilt high-velocity fans which force airflow across their internal components, it is often necessary to buy additional air cooling containers.
When it’s cold outside, the mining equipment is cooled using a mixture of ambient air and hot recirculated air.
Chillers and air handlers, which consume a lot of energy, are frequently required to improve the efficiency of air cooling.
What is Immersion Cooling?
Using this method, mining rigs can be cooled without losing money, and it is a rapidly developing technique. Immersion cooling is the process of completely submerging, or immersing, the mining rig in a thermally-conductive liquid with better insulating qualities than regular air.
There are two basic approaches to immersion cooling namely single and double phase immersion cooling.
The parts are submerged in a dielectric fluid in a single phase, which is typically an engineered fluid or oil of some kind. As the fluid is pumped and circulated around a tank to help remove heat, the heat produced by the IT components is absorbed by the fluid.
On the other hand, the double phase entails sealing servers inside a bath of specially designed fluorocarbon-based liquid. The liquid undergoes a phase change from liquid to gas upon boiling. The liquid form of the vapor is then recondensed and recycled through the system.
Regardless of the method employed, immersion cooling is extremely efficient, and about 40% of the heat is captured and used to power the mining rig. It also boasts a capacity for heat rejection that is roughly ten times greater than air cooling.
Air Cooling VS Immersion Cooling Technologies
Although air cooling is frequently employed, everyone agrees that immersion cooling will eventually replace it in Bitcoin mining.
For a number of reasons, immersion cooling technology is more effective than air cooling when it comes to cryptocurrency mining. They include:
- Hash Rate Increase:
The importance of hash rates in cryptocurrency mining can not be overstated. However, installing ventilation fans as part of air cooling often lowers hash rate. Immersion cooling, which is used with a variety of mining equipment, including Antminer S19 series miners, dramatically increases a hash rate by switching out fans for immersion ware. There is also less energy lost when there are no fans or air handling.
- Longer Antminer S19 Series Miner’s Lifespan:
The lifespan of mining equipment is something that miners are constantly looking to maintain and extend. Additionally, the heatsinks of each ASIC in Air crypto mining farms are filled with airborne particles that are drawn into them, which causes overheating and a reduction in lifespan. Additionally, equipment corrosion and contamination are frequent side effects of air cooling.
Immersion cooling is recommended to address these shortcomings. For longer periods than air cooling, it enables ASICs to operate at full capacity. By removing contamination, overheating, and corrosion, it also extends hardware lifespan by 4-5 years.
- Noise and Dust Reduction:
As the miner puts in more work, heat and noise levels in standard air-cooled mining rigs rise. On the other hand, immersion cooling bitcoin miners provide absolute noise reduction. This is due to the fact that the fans, which are the main noise generators, are taken out before immersion. Bitcoin miners that use liquid cooling are also dust-free. With less frequent cleaning required, equipment will last longer.
- Efficiency in Power Consumption:
ASIC fans and facility fans are significant energy consumers in mining. By switching to immersion cooling, miners can reduce their reliance on this energy-guzzling machinery and save up to 50% on energy costs. Additionally, compared to air, the liquid is a much better heat conductor. Because immersion cooling requires little energy input, it is a more effective cooling system.
In addition, the reduction in electricity consumption allows miners to invest in more mining equipment if they wish.
- Cost Optimization:
Although air cooling containers are less expensive, their high operating costs quickly render them unprofitable. On the other hand, immersion cooling has the lowest overall cost of ownership.
Immersion cooling clearly wins when the cost of upkeep and the cost of new equipment are taken into account, along with the decrease in electricity costs. This cooling technique offers a staggering 80% cost savings for a doubled efficiency.
It is clear from a scale’s readings that immersion cooling containers are preferable to air cooling systems. In addition to its many benefits, immersion cooling also offers a tidy, peaceful, stable, and comfortable working environment.
How Hot Does An Antminer S19 Get?
Maximum PCB temperatures for Antminer S19 Bitcoin miner devices range from 75 to 85 degrees Celsius. The table below displays the specific model’s detailed information, including Antminer S19 XP, Antminer S19a Pro, Antminer S19a, Antminer S19j, Antminer S19j Pro, Antminer S19, and Antminer T19
The ideal Antminer ambient temperature range is from 15 to 35 degrees Celsius.
The miner’s intake air temperature in particular needs to fall within this range.
The intake air temperature may be too high despite the room’s relative coolness due to dust accumulation or other factors. If you must, please clean the miner.

What Happens When Antminer S19 Series Miner Overheats?
It is not a surprise that miners frequently use creative solutions to keep their machinery from overheating.
Some of the Reasons to Avoid Overheating in the Antminer S19 Series Miner Include:
Decrease in Hash Rate
Before we continue, we must define what the hash rate is. Hash rate is a gauge of how quickly a cryptocurrency miner’s computer can perform intricate calculations.
This is inarguably the most important feature in selecting mining equipment because it often determines productivity.
When the machine overheats, it makes an effort to reduce workload, which essentially lowers the hash rate. The hash rate will remain below average until the miner cools.
Lower Power Efficiency
It is well known that mining for bitcoin uses a lot of energy. The electricity used by Antminer S19 series miners is already discouraging, but when a machine overheats, it gets worse. Due to the lower hash rate caused by overheating, more electricity is consumed while fewer results are produced. The two factors together reduce output and revenue.
Maintenance and Lifespan
A major disadvantage of overheating is the random shutdown it causes in miners. Mining machinery will not only shut down if it overheats, but it will also malfunction more frequently. Last but not least, the lifespan of a miner from the Antminer S19 series that overheats constantly will be drastically reduced. For instance, if exposed to high temperatures, a miner from the Antminer S19 series with a lifespan of three to five years can degrade in a matter of months.
This relates to the earlier ideas. Electricity consumption and maintenance costs make up the majority of mining costs. Miners need twice as much money for upkeep and electricity when they frequently overheat. As a result, Antminer S19 series minerF are frequently less profitable.
Overall Reduction in Efficiency
This conclusion is made because equipment overheating can have an impact on power consumption, cost, and even equipment lifespan. When these factors are taken into account, the Antminer S19 series miner performs less productively than anticipated. As a result, equipment breakdown, increased power consumption, and decreased profit are all directly caused by overheating.
Overheating is terrible. The productivity and financial viability of miners using Antminer S19 series are both impacted. So how do we stop overheating? What strategies can we use?
Summary: Cool Bitmain Antminer S19 Series Miners
Although many miners consider the cost of immersion to be extremely high, it is actually quite small when compared to the price of new-generation ASIC hardware. Immersion probably won’t make sense if you don’t have easy access to capital or you’re setting up a smaller operation and using older, less effective mining equipment. However, immersion is probably worthwhile for well-funded miners who are setting up industrial-scale operations, particularly in regions with hot summers like Texas and the rest of the southern US.
Can You Water Cool An Antminer S19 Series Miner?
By using water to cool the Antminers, miners can run at a higher hash rate for a longer period of time without overloading the system and shutting down. The long-term cost-effectiveness of water cooling using microconvective technology is also increased by the fact that it requires little maintenance.
Do Antminer S19 Series Miners Need Cooling?
Miners from the Antminer S19 series generate a lot of heat.
If left unattended, the high temperature could damage the hardware or even be a fire hazard. Therefore, miners often install dedicated cooling systems to reduce the temperature of their mining facilities.

Does Liquid Cooling Increase Hashrate?
The most economical way to get the highest hashrate out of any ASIC or GPU-based miner is with single-phase, liquid immersion cooling (SLIC).
What Liquid is Used in Immersion Cooling?
Further, for safety reasons, these fluids need to be “dielectric,” meaning they do not conduct electricity. The dielectric fluids used for immersion cooling today fall into two categories: oils (synthetic, mineral, bio) and engineered fluids, such as 3M’s Novec or Fluorinert lines.
