Many cryptocurrency miners, driven by the desire to maximize profits, often make the mistake of overlooking the importance of investing in adequate cooling solutions for their ASIC miners.

This fundamental mistake stems from either greed or a lack of awareness regarding the technical aspects that need to be managed and optimized in mining operations. Neglecting the cooling aspect can have dire consequences, as overheating can swiftly lead to the collapse of an entire cryptocurrency mining venture.

It is crucial to comprehend the various risks faced by owners of ASIC miners in the pursuit of mining digital coins. The multitude of dangers should prompt a reconsideration of any nonchalant approach to the cooling problem associated with ASIC devices for miners.

The necessity of heat removal from ASIC devices is underscored by a range of probable consequences:

Gradual Decrease in Hashrate: Overheating leads to a progressive decline in computing power, causing a reduction in hashrate.
Increased Computing Errors: Elevated temperatures disrupt the normal functioning of specialized chips and processors in ASIC miners, resulting in more frequent errors during computing processes.
Shortened Operational Lifespan: Overheating contributes to additional strain and accelerated wear of ASIC components used for mining digital coins, ultimately reducing the operational availability period of the equipment.
General System Failures: Excessive heat can lead to overall failures within the circuitry of the ASIC device, as well as episodes of spontaneous disconnection during the mining process.
Risk of Fire: In extreme cases, excessive heat can cause boards to ignite and flames to form. This poses an immediate danger not only to the affected equipment but also to the surrounding premises, the health, and the lives of the miners themselves.

Unfortunately, many beginners tend to underestimate these dangers and consider them to be inconsequential. It is essential for everyone to independently analyze and understand the significance of these factors.

The crucial point to grasp is that overheating mining equipment inevitably leads to a decline in business profitability. Profits will progressively decrease, and various situations requiring additional expenses will arise.

Recognizing these nuances, experienced miner go to great lengths to ensure consistent and effective cooling of their ASIC devices. Failure to address this factor can be detrimental to the mining process, resulting in critical moments for both the equipment and the overall effectiveness of the operation.

Remember this: Sustaining normal mining activity is impossible without employing effective heat removal methods for ASIC devices, ensuring a constant and powerful cooling effect.

In addition to local measures taken to control overheating, it is important not to overlook the impact of the general microclimate. During the summer, achieving proper cooling for ASIC devices is relatively straightforward as coolers and other methods facilitate adequate heat exchange.

However, significant challenges arise from October to May. Cooling ASIC devices becomes more difficult during winter due to the changing humidity levels in both the indoor and outdoor environments. Employing methods to remove heat from ASIC devices and locally decrease surface temperatures can result in condensation. It is a well-known fact that moisture can rapidly damage electronic equipment.

Therefore, it is crucial to address these challenges and adopt suitable measures to mitigate the risks associated with condensation and moisture when cooling ASIC devices in cold and freezing conditions.

In accordance with regulatory guidelines, cooling methods for mining ASIC devices should strictly adhere to the recommended indoor air temperature. It is essential to fully follow the manufacturer’s instructions.

For instance, the Antminer S9 guarantees high-quality and efficient operation within an atmosphere where the temperature range is maintained between 0 and 40 degrees Celsius (above zero).

When utilizing the AvalonMiner 821, it is also possible to operate within a negative environmental temperature. However, the lower limit for the normal functioning of the ASIC is -5 degrees Celsius.

Given these specifications, it is important to consider the specific heat exchange processes involved when implementing cooling methods for ASIC miner.

When airflow comes into contact with the surfaces of the active components used in mining cryptocurrencies, instantaneous heating occurs. If the room temperature exceeds the technical standards specified for the device, it will lead to overheating of the mining equipment. Conversely, if the temperature falls below the instructed range, condensation can occur.

Therefore, the selection of a cooling method for ASIC miners should be approached with great care. It is crucial to calculate the necessary parameters and continuously monitor the temperature conditions to ensure optimal performance and prevent any potential issues.

There are several solutions available for cooling miners, but three widely used methods for heat removal from ASIC devices stand out. The third method, which involves renting a space, can be considered a combined option.

These methods have proven to be highly effective in regulating the thermal environment and creating optimal conditions for mining cryptocurrencies.

Active ventilation

To ensure proper cooling for ASIC miners, it is essential to house them in premises that facilitate the movement of air flows. This straightforward, efficient, and cost-effective method is highly recommended for cooling mining ASIC devices.


An ideal cooling system should include the following components, in addition to the built-in coolers:

Air conditioners or a powerful central cooling unit.
Channels or pipes for the movement of air.
Ventilation holes in the walls.
Heat exhaust points.

While compact and modern cooling systems may be more convenient, they can be quite expensive, and their operation may require ongoing investments.

On the other hand, using older models of air conditioners for heat removal from ASIC devices may lead to more significant problems, such as repair and modernization issues. However, this option might be suitable for beginners seeking to earn their initial profits from cryptocurrency mining.

For most miners, equipment within the mid-price range is sufficient. These models are effective, albeit slightly bulkier in size.

Immersion cooling of ASIC

The most advanced and innovative method of cooling ASIC miners involves the use of special cooling cabinets and a specific liquid coolant.

Although these cabinets are commonly referred to as “cabinets,” they are actually compact pools or baths designed for this purpose.

The liquid coolant used for heat removal possesses several key properties, including:

Optimal thermal conductivity to efficiently transfer heat.
Relatively low boiling point to facilitate heat removal.
Minimal or no electrical conductivity.
Suppression of electromagnetic field generation.

ASIC miners are submerged in the liquid coolant. If the mining equipment experiences excessive overheating, the coolant begins to boil, effectively carrying away the heat generated by the ASICs through evaporation.

Most cabinet models are equipped with additional condenser systems. These systems create a closed cycle where the evaporated coolant is cooled, condensed back into liquid form, and returned to the tank for further use.

Currently, the immersion cooling of ASIC miners in cryptocurrency mining devices is primarily implemented using 3M Novec-engineered Fluid. However, there are other noteworthy alternatives available.

Rent of space with cooling

The method of renting spaces with cooling for ASIC miners is a somewhat controversial approach that cannot be categorically classified as a “clean” cooling method. However, its primary objective remains the same – to improve heat removal from ASICs, even if it involves using someone else’s equipment.

Renting spaces in a mining hotel is the simplest option available. Users transfer their crypto-mining devices, which are then placed in rented premises. These rooms are specifically designed to provide optimal conditions for heat removal from ASIC miners, ensuring a stable microenvironment.

A reputable mining hotel not only offers optimal cooling but also provides high-quality power supply systems that eliminate voltage fluctuations or power interruptions. The electrical wiring is reliable, backup batteries are in place, and the flow of electricity is closely monitored.

While renting space with cooling may reduce overall business efficiency, there are several advantages for the mining equipment owners, including:

Creation of better temperature conditions.
24/7 maintenance and support if the service is purchased.
Protection against moisture-related issues.
Uninterrupted power supply.
Constant security measures, which is crucial given the substantial cost of mining ASIC devices.

Additional cooling factors

To ensure the stable functioning of devices used for mining cryptocurrencies, it is crucial to implement comprehensive measures.

In addition to focusing on methods to control equipment overheating, attention should be paid to factors that generate heat and other important nuances, as noted by experts:

Prior to launching ASIC miners, it is essential to verify the thermal paste. This special thermally-conductive substance helps eliminate temperature variations between different components. Even new models of ASICs may have dried thermal paste due to prolonged storage. It is advisable to replace the thermal paste, particularly in Bitmain miners.
Another significant aspect is the possibility and parameters of ASIC boost. These parameters determine the feasibility of operating the device beyond its normal capacity, resulting in increased heat generation. Overheating of mining equipment leads to reduced efficiency in mining digital coins. It also compromises the stability of computing processes, making it more challenging to generate profits from cryptocurrency mining.

By addressing these aspects and implementing appropriate measures, miners can improve the stability and efficiency of their mining operations, enhancing their potential to earn revenue from crypto-mining endeavors.


Excessive heat poses a significant challenge in the demanding industry of cryptocurrency mining. As miners work to compute new blocks for decentralized blockchain projects, their devices emit a substantial amount of energy, resulting in increased ambient temperatures.

Fortunately, developers are actively researching methods to control the overheating of mining equipment and implement optimal solutions. The cooling methods available for ASIC miners encompass a wide range of options. However, crypto-miners often gravitate towards three primary directions to enhance profitability, quality, and safety of their operations.

These directions include:

Active ventilation: This method involves implementing effective ventilation systems to regulate temperature and airflow around ASIC miners.

Immersion cooling: Immersion cooling is another popular approach, where ASIC miners are submerged in a special cooling liquid to efficiently dissipate heat and maintain optimal operating temperatures.

Renting premises with specialized mining hotel conditions: Some miners opt to rent spaces in mining hotels that offer dedicated facilities designed for cryptocurrency mining. These spaces provide controlled environments with suitable cooling solutions and other necessary amenities.

Regardless of the scale of the mining business, it is crucial to approach cryptocurrency mining with care and ensure proper temperature control within the operating range. Additionally, considering additional cooling techniques and optimizing heat exchange between the active elements of the mining modules are vital for success in mining digital coins. Efficient heat removal from ASIC miners plays a significant role in achieving these objectives.
