Page 31: Fan Adjustment And Noise Level Optimization
Fan adjustment and noise level optimization With its Antminer S9 and solid housing, the 21energy Ofen has a high mass. Shortly after switching on the Ofen, all components are still cold and warm up during operation. The fans of the Antminer S9 are set at the factory to cool the chips installed on the hashboards to 79°C. - Page 32 The fan speed depends on the ambient temperature in which the Ofen is operated and the resistance. The resistance can increase over time if there is too much dust in the dust filter on the underside of the Ofen. For this reason, it should be cleaned regularly (the interval depends on the level of dust in the environment in which the Ofen is operated).
- Page 33 For example, if the fans of the Ofen oscillate between 28 and 32%, you can also set the fans to a constant 35%. Many people will find the slightly higher but constant noise level more pleasant than the oscillation between 28 and 32%.
- Page 34 80°C. This is the maximum temperature that the Bitcoin Ofen can currently reach. Example: You set up the 21energy Ofen in your home and start up the Ofen at 19°C. The maximum expected temperature in your home is 25°C, for example. This means that it is currently 6°C colder than the maximum expected ambient temperature.

This means that you are rewarded with the use of the Braiins Pool every 300 minutes on average for operating the 21energy Bitcoin Ofen.

This balances out over time and has a negligible effect on the total reward over a longer period of time. -
