Eight BM1370 chips, 12 TH/s at 200 W: the most powerful air-cooled home miner in the store
The NerdOctaxe Rev 3.1 is the strongest air-cooled miner in our range: eight BM1370 chips, 12 TH/s at 200 W. It is an open-source design from the Open Source Miners United community, built as one board with one power input, one display and one AxeOS dashboard.
Eight chips on one board
Eight BM1370 ASICs, the chip generation of the Antminer S21 Pro, hash side by side on a single board. At 200 W that works out to about 17 J/TH, so the step from four chips to eight adds hashrate without giving up efficiency.

Cooling and noise
The Rev 3.1 is air cooled and is designed to run quietly, with fan speed following chip temperature in AxeOS. Two hundred watts of heat still need a spot with airflow, not a closed cupboard. If the room has to stay silent, the NerdOctaxe Hydro moves the same heat into a water loop.
What it costs to run
About 200 W around the clock is roughly 144 kWh a month. At 30 cents per kilowatt hour that is about 43 euro a month; your own tariff decides the rest. Anyone buying a miner this size should do that sum first.
Display and dashboard
The 1.9-inch colour display switches between three views: mining performance with hashrate, power, temperature and efficiency, the Bitcoin price with system stats, and pool statistics with shares and difficulty. Everything else, from pool settings to firmware updates, lives in the AxeOS web interface on your home network.
Who it is for
For solo miners who want the most hashrate one air-cooled device can deliver and have a ventilated place for it. If twelve terahash is more than you need, the NerdQAxe++ is the four-chip board of the same family.
Setup
Built-in Wi-Fi on the ESP32-S3: power on, join the network the miner opens, enter your Wi-Fi, pool and Bitcoin address. Our NerdQAxe setup guide applies to the NerdOctaxe as well. Hashrate, power and efficiency of every miner side by side: miner comparison.
Customer reviews
18 Sep 2026La configuración fue rápida en mi caso. En NerdOctaxe Rev 3.1 valoro sobre todo el ventilador más grande frente a los pequeños miners de un chip; tener AxeOS directamente en el navegador también fue una razón para elegirlo.
14 Sep 2026NerdOctaxe Rev 3.1 has been running for a couple of months without needing much attention. In practice I appreciate the eight BM1370 chips and the big step up from the smaller NerdAxe boards. I use it more as Bitcoin infrastructure than as a profit machine.
13 Sep 2026NerdOctaxe Rev 3.1 fonctionne depuis deux semaines sans demander beaucoup d'attention. En pratique, j'apprécie le gros saut par rapport aux petites cartes NerdAxe et les huit puces BM1370.
9 Sep 2026Die Einrichtung war bei mir schnell erledigt. Bei NerdOctaxe Rev 3.1 schätze ich vor allem die acht BM1370 Chips; die rund 12 TH/s Leistung war ebenfalls ein Grund für den Kauf. Er steht bei mir in einem kleinen Regal mit dem restlichen Netzwerkzeug.
9 Sep 2026Ich nutze NerdOctaxe Rev 3.1 seit zwei Wochen auf meinem Schreibtisch. Im Alltag schätze ich besonders die acht BM1370 Chips und die rund 12 TH/s Leistung. Ich nehme lieber eine stabile Lüfterkurve als maximalen Takt.
8 Sep 2026Ich bin von einem kleineren Miner umgestiegen. Bei NerdOctaxe Rev 3.1 schätze ich vor allem den großen Leistungssprung gegenüber den kleineren NerdAxe Boards, aber auch den größeren Lüfter im Vergleich zu den kleinen Single Chip Minern.
