How to cool it down if the miner's temperature is too high? 

Regardless of the size of the mining farm, the problem of cooling is inseparable. People are afraid of high temperatures, and so are our miner rigs. If the chip temperature is within 80, it is normal. If it exceeds 80 or too high, the chip will be damaged (and this damage is permanent), the hash rate will also decrease, will shorten the miner's life. The result is a loss of revenue.
This should also be taken into consideration when choosing mining farms.

How to cool down?

The simplest and almost zero-cost method is, of course, to wait until it rains and enter the factory with a cool breeze, even if the temperature is high. But 365 days a year, it is impossible to rain every day. So have to think of other ways.
The miner generally has basic cooling measures, including cooling fans, heat sinks, and other designs.

But this is not enough. In the actual operation process, the miner runs 24/7 hours, which is also affected by the environment. One with two miners are easy to handle. However, thousands of miners are running in the same space simultaneously. If it is winter, it will be good. In hot summer, it will be a sauna.
For the miner, the heat is brutal to release, the release is slow, the temperature generated is higher, it is more likely to be damaged, and the life of the miner will be shortened. Therefore, it is not enough to use the cooling device with the miner.

Let's talk about a few general points first, which can be used as a reference: 

First, ventilation, but do an excellent job of dust prevention. 
It is recommended that you use a negative pressure fan; its primary function is to circulate the air to achieve a good heat dissipation effect.
Blinds and screens can be installed, as well as dust-proof nets and sand-proof nets, conducive to dust prevention. Dust prevention should be planned and carried out simultaneously as ventilation work.

Second, the water curtain device or the water cooling fan.
The water curtain is used to cool down. It is a unique paper honeycomb structure material, which uses the principle of "water evaporation absorbs heat."
Simply put: water flows from top to bottom on the corrugated fiber surface of the wet curtain, like a small waterfall. When the air passes through this layer of water curtain, the water above will absorb heat, and the hot air will become a cool breeze. Imagine a gust of wind blowing from outside when it rains in summer.
However, some computer rooms are not suitable for installing water curtains so that water-cooled fans can be used, and the reasons are similar.
Third, regular dust removal.
The overheating of the miner is not necessarily due to the high temperature but also because of too much dust. The accumulation of dust will significantly reduce the cooling effect of the miner itself.
It is best to clean the inside of the miner regularly, which can be a month. After that, you can use an air compressor to blow from the air inlet of the miner to the air outlet. However, the experience of each mining farm may be different, as long as the ash can be cleaned effectively (on the premise of not damaging the miner).

Even if there is a fan dust filter, regular cleaning is recommended.

Fourth, move to a place with a lower ambient temperature.
It is recommended to move miners to places with lower temperatures such as rivers or mountains (be careful of rainstorms near the river). If a miner mining by himself, this method may not be easy or ideal. It is recommended to find a place with low temperature and ventilation.

When you are looking for miners to host, the following points can be used as a reference for inspection:

Some mining farms will do this:
The ventilation of the mining farm generally involves these cooling devices, including fans, ceilings, side panels, rain clothes, poles, racks, etc.
The fan is generally installed on one side of the equipment room, while the other side is provided with a side panel. The side panel will use the strut to realize the function of opening and closing, and the side panel and the fan form the air inlet and outlet, which well achieves the purpose of ventilation.
There are rain clothes on the left and right sides of the side panels, and sometimes the ceiling can be retracted.

Some mining farms do this:
Use a single-row combined shelf, but the shelf will be high to the top (more miners can be placed), and then cooperate with a negative pressure fan to prevent hot air from accumulating and backflowing in the computer room. A water curtain device is added to further cool down.
Some also do this:
The multi-row combined shelves are staggered and placed. The devices used are negative pressure fans, water curtains, and water cooling fans, which cooperate with each other.
The air inlet and outlet are parallel to the miner so that an air duct is formed in the room, and there will be a suitable interval between the miners on the rack so that the wind can come and go freely, and the ventilation effect is good.
Of course, some bosses also can choose central air conditioning.
Summarize
The heat dissipation of the computer room is not achieved by a single tool or equipment. The best results can be achieved by coordinating multiple tools and good matching.
Whether a retail investor or a mining farm, the most important thing is "ventilation" in the final analysis to achieve better cooling.
If you only have one or two miners, you can "fix investment," although the income is not high. The so-called "scheduled vote" means not running for 24/7 hours, depending on the situation, or switching the miner on time. This can cool down very well.
