Mining rigs are set into operation for a continuous period. It causes a lot of heat in the environment, and things may seem like a boiler. A suitable cooling arrangement is necessary to keep the mining rigs cool if you want them to operate smoothly.
In the below discussion, we will portray a complete guide and methodology for keeping mining rigs cool and perfectly feasible during their operational period.
Position Of Cooling Fans
The position of cooling fans is of paramount importance for cooling mining rigs. Generally, cooling fans are installed behind and in front of mining rigs. This is the general practice and is followed by everyone. The fans behind the rigs are larger than the fans on the front.
You have the option to alter the speed of the fans behind the mining rigs from the three variants, which are low, medium, and high. On the other hand, the cooling fans on the front of mining rig throw air at very high pressure and speed, normally at 2 miles per hour.
You can check the intensity and speed of outcoming air using an Anemometer. The DC cooling fans at the front play a pivotal role in propelling out the heat from the GPU mining rigs. Choosing the right dc cooling fans for the GPU mining rig will impact the performance of mining rigs as they will not get overheated and will become durable.
It will also significantly decrease the electricity consumption as the cards and fans will run softer without generating immense heat in the process. Moreover, you will surely want this arrangement to work with as minimum fans as possible. One will not like to run their cards on 80 or 90 fans.
Solid Shelving for Mining Rigs
Most people prefer to go for open mining rigs. However, this is not the most desirable option if you wish to keep your mining rigs cool. The problem with open mining rigs is that they will transfer the heat from one rig to another, and the heating problem will keep on increasing. Open rigs on wire racks may seem easy to go but will have more devastating impacts in the long run.
Solid shelving is the best option for stacking mining rigs. This arrangement will separate the mining rigs, and each of them will be self-contained. In this arrangement, you will not have to worry as the heat of the bottom rig will not come up through the wire racks to impact the rigs above.
The bottom line regarding this arrangement t of solid shelving is that the heat of every rig will be confined to its stack.
Stacking The Mining Rigs
A rig with 30, 70 cards, and AMD’s will emit less heat as compared to a mining rig of 30, 80 along with server power supplies. The amount of heat generated by a mining rig is proportional to the size of the rig. Therefore, the bigger the mining rig, the more heat it will dissipate.
The placement of rigs in the solid shelving is done according to the heating and the size of the rigs. Keep the bigger rigs down, close to the floor. Similarly, place the smaller rigs on top of bigger rigs.
Bringing The Fresh Air
A continuous supply of fresh air is essential to keep the temperature of mining rigs cool at all times. We cannot circulate the same air again and again as it will create a boiler-like environment in the place. Therefore, there is normally a big louvers installed in mining containers for air inlet, the louvers normally come with protective net to prevent birds or other big bugs coming in. Installing the reusable and washable filter pad can help to filter the dust of the intake air.
The mining rigs are kept at a distance of 15 inches from the walls to allow the penetration of fresh air from behind the rigs. The distance of 15 inches will serve a few added benefits along with providing room for fresh air. The first dynamic advantage is that you can keep the wiring system in this space. The second advantage is that it will give you enough space to carry out any maintenance activities easily.
Therefore, installing louvers and keeping the mining rigs at a distance of 15 inches from the wall is a prerequisite to keeping the air supply to cool the mining rigs.
Using Exhaust Fans to Bring in Fresh Air
There is a mechanism to bring fresh air into that 15 inches of space between the mining rigs and the walls. For this purpose, commercial fans were also used, but they were not much effective as that of an industrial exhaust fan.
An industrial exhaust fan does the job more quickly than the commercial fans. It has a flexible hose at the inlet, and the industrial exhaust fan can move a high volume of air per minute. Normally, the capacity of moving fresh air is 16,000 cfm (cubic feet per minute). It is part and parcel to bring the fresh air and keep the mining rigs cool.
Whole House Fan for The Purpose
It is a well-engineered fan because, unlike other whole-house fans, it is soundless in its operation while driving in the required amount of fresh air. Therefore, it is the best option if you want your mining rigs in a cool and noise-free environment.
Furthermore, it has an ECM (Electronically Commutated Motor), which has low wattage. It is mounted on the joists and is placed above the mining rigs. There is no noise when it is operational. The best attribute about this product is that it has no complex electrical wiring system.
It comes with a cord of wire which you can plug into the power supply. You do not need to assemble any arrangement of wires to use this product. In addition to being free from wiring hassle, the system is governed by a remote-control kit.
All the options, such as setting the fan on high or low frequency along with the hours of operation, can be set using this remote kit. By far, it is the best product for cooling mining rigs.
In conclusion, there are various of ways to cool a mining farm, and a cooling fan is important for a mining rig because it helps to keep the GPU cool and prevents it from overheating. The system design depend on the size of your mining farm and the heat it generates. If you are unsure which system is right for you, consult with a professional or do some research online.
