L3 mining machine fan

1. No matter what kind of computer, noise is basically a fan problem. If you can't clean up the st on the fan, replace it

2. Use your brain to know that the fan can't mine... Graphics card has powerful parallel computing power, which is much more efficient than CPU when it is used to mine. In the past, many people used to mine with graphics card, resulting in the high price of a card. But now, bitcoin is collapsing. No one is digging. In the later stage, people didn't have to dig with graphics cards. They used specially designed circuits and quick miners. They couldn't even earn their electricity bills.

3. Bubble milk powder generally choose tap water at home to boil and cool, do not choose mineral water, which contains some substances not suitable for the baby.

4. The first way is to replace it with a new fan
the second method is: if the fan has a shaft core which can be oiled, it can be removed, the st on it can be cleaned thoroughly, and then a proper amount of engine oil can be dropped into the shaft core of the fan, so that the fan can operate normally after operation.

5. How to cool without fan

6. The chip consumes a lot of power and generates a lot of heat. Generally more than 400W

7. If the temperature of the notebook is too high, it will cause card, crash, etc., and make it aging rapidly... It's necessary to buy a radiator. Buy notebook radiator, generally depends on the notebook material, fan size, mute degree, angle support, USB port and other aspects to judge. General fan large, aluminum panel, quiet, such a calculation is better. Some of the prices will also be higher. The best brand of notebook radiator in the market should now be Kyushu Fengshen. Their radiator has many categories, novel and fashionable shapes, and their market share is very high. There are cool cool supreme, TT, it's OK, there are many other brands..

8. Using computer detector to see the actual water temperature of data stream and judge the fault

9. I don't want you to turn on the air conditioner three times. It sounds like a fan. Then you must make it clear that the air conditioner rings as soon as you turn it on. It's still full load or uphill. Or what is the word? The pressure of this air conditioner is relatively high. It belongs to a fan that operates at high speed. Actually, if you turn on the blower, it will sound. Especially between second and third gear? There's friction sound.

The noise may be that the blades of the cooling fan are unbalanced or some foreign matters may fall off.

10. What is Merkle tree

Merkle tree is a kind of tree (the tree in data structure), which is mostly called Merkle hash tree on the Internet, because all nodes of Merkle tree constructed by it are hash values. Merkle tree has the following characteristics:

1. It is a kind of tree, which can be binary tree or multi tree. No matter how many trees are, it has all the characteristics of tree structure
2. The value on the leaf node of Merkle tree is specified by you, which mainly depends on your design. For example, Merkle hash tree takes the hash value of the data as the value of the leaf node
3 the value of a non leaf node is calculated according to the values of all the leaf nodes below it, and then calculated according to a certain algorithm. For example, the calculation method of Merkle hash tree's non leaf node value is to combine all the child nodes of the node, and then hash the combination results to get the hash value.
