How hot can my garage get before the S21 starts throttling?
AsicProfit Support AsicProfit · 2026年10月24日
Bitmain rates the air S21 for 0 to 45°C intake air, higher than the S19 series. In tests, stock firmware ran at full spec at 10 and 20°C and began underclocking near 40°C. Above 900 m altitude the limit drops 1°C per 300 m.

My S21 stops hashing after a few minutes and shows a board error, any ideas?
AsicProfit Support AsicProfit · 2026年10月23日
Read the kernel log first. Common causes are a hashboard knocked loose in shipping, a bad data cable or an unstable power supply. One owner fixed this by replacing a faulty supply cable. Reseat cables and test boards one at a time. If it is under Bitmain's 365 day warranty, open a repair ticket rather than opening the case.

S21 immersion, what oil temperature and flow does it need?
AsicProfit Support AsicProfit · 2026年10月22日
Bitmain lists the S21 Imm at 239 TH/s and 3,824 W in normal mode or 301 TH/s and 5,569 W in high mode, with inlet oil at 30 to 55°C and about 1 cubic metre per hour of coolant flow. It runs on three phase 380 to 415 V. High mode is less efficient.

What does the S21 Hyd need for cooling and power?
AsicProfit Support AsicProfit · 2026年10月5日
The S21 Hyd makes about 335 TH/s at 5,360 W on three phase 380 to 415 V. It needs 8 to 10 L/min of deionized or pure water per unit, pressure up to 3.5 bar, pH 8.5 to 9.5, DN10 connectors, and inlet water up to 35°C in normal mode. Replace coolant once conductivity reaches 100 microsiemens per cm.

what plug does the S21 come with, C19 or C20?
AsicProfit Support AsicProfit · 2026年9月29日
Bitmain lists a P33 to P13 or C20 to P13 cord included with the air cooled S21. The P13 end goes into the miner's power supply; the C20 end plugs into a C19 socket on a PDU. Hyd and immersion versions use different power supplies, and the Hyd cord is not included.

Will an S21 run on a 16A circuit?
AsicProfit Support AsicProfit · 2026年9月17日
It is too tight. Bitmain lists about 3,500 W at the wall for the 200 TH/s air S21, on 220 to 277 V with up to 20 A on one input wire. At 230 V that is over 15 A continuously, which leaves no margin on a 16 A breaker. Give it a dedicated 20 A or larger circuit sized by an electrician.
