If you make a comparison of the fan power of this model with the WhatsMiner 20S-68T miner machine, you will find that there is a reduction in fan power. The WhatsMiner M30S-88T miner machine uses a 7.2 A fan and the WhatsMiner M20S-68T miner machine uses a 9 A fan. Thus, there will be a reduction in fan noise along with a reduction in power consumption.

You will be able to find a 6-core flat interface on the fan at the front. The fan at the rear side will have a 4-core 4P interface.

Die-cast aluminum alloy is used for the making of the chassis of the WhatsMiner M30S-88T miner machine. There is a close arrangement made in the system that allows the insertion of the hash board into the system via the groove.

Test Information of the WhatsMiner M30S-88T miner machine

 

The noise in the ambient was found to be 44 decibels during the test.

Whatsminer M30S Review 24

 

Once you power on the WhatsMiner M30S-88T miner machine, it will tune the frequency automatically. It will happen within half an hour. You can see a fluctuation in the hash rate at this point in time, and it will be showing 24T. You can expect the program to restart automatically after another half an hour. Now, you will be able to see a standard hash rate value. After that, the miner machine will be in the normal operation stage. The temperature on the hash board war around 72 degrees Celsius, and the temperature near the air inlet is around 25.6 degrees Celsius. The temperature near the air outlet is around 60.4 degrees Celsius, and the temperature on the sides of the WhatsMiner M30S-88T miner machine is around 36 degrees Celsius.

Now, we need to measure the temperature in the power supply section also. The temperature near the air outlet is around 55 degrees Celsius. The temperature at the copper connection is 31 degrees Celsius. The temperature measured on the power cable is 26 degrees Celsius.

The noise level on the machine is around 86 decibels when the WhatsMiner M30S-88T miner machine is in normal operation. The total power consumption is about 3345 Watts. The power consumption as per the specifications of the WhatsMiner M30S-88T miner machine is 3344 Watts. So, the measured power is a consistent one.

A 24-hour test was also conducted on the WhatsMiner M30S-88T miner machine to find the hash rate of the miner. The average hash rate displayed by this mine is around 88.4T.

The total hash rate which the mining pool has received is 89.11T for 24 hours. This value shows that the hash rate is stable. We got a power ratio of 37.53 Watts/ T.

So, the WhatsMiner M30S-88T miner machine is running in a stable condition. The miner was also put for a long-term test. The performance of the miner was satisfactory during the long duration runs. There was only a small variation in the computational power of the miner, temperature, and power.

The new modified power supply unit in the miner has helped to reduce the weight of the miner. Thus, it is more easy to carry around now. It is also easy for maintenance because of the new design.

The interface of the fan, both on the front as well as the rear side of the miner, is found to be inconsistent. This inconsistency has led to some spare parts trouble at a later stage. We hope the manufacturer makes some changes to improve this side during the mass production stage.

The manufacturer has also informed that there will be mode models for the M30 series. So, we can expect more models to be announced in the coming days.

So, the WhatsMiner M30S-88T miner machine is fully evaluated by our team. The hash rate of the system is found to be 88T, and the power ratio is 37,55 Watts. These values are really shocking. These values will definitely help the mining guys to generate more revenue. So, this model is going to be a huge success.
