What is the average hashrate labeled as (GH/S(avg)) at the topic of the miner status page?
https://i.ibb.co/sVdnPfC/avg.pngIf it's within the normal range of 13.5-14.5th then you don't need to worry about the readings that show at the bottom for each chain individually, and most importantly would be the accepted hashrate at the mining pool, such weird readings usually go away by flashing a firmware, but if they don't really impact the actual hashrate - just ignore them.
The hashrate above is normal and the numbers at the pool as well. It just confuses me because the device goes off and on every 10 min. Can the fans be the problem?
