Nerdaxe Gaia Copper Pro | 3 TH/s

The Nerdaxe Gaia Copper Pro is the Nerdaxe Gaia with Thermalright’s AXP60 cooler fitted. Instead of the small stock heatsink with its 40 mm fan, the BM1373 carries 210 g of copper, two heat pipes and a 60 mm fan. With that headroom the chip comes factory-set to around 3 TH/s on roughly 33 W, about 11 J/TH. There is nothing for you to overclock. The Gaia Copper Pro is available to pre-order and ships from 7 November 2026.

Everything else you know from the Gaia: ESP32-S3, 2.4 GHz Wi-Fi, USB-C, the 1.9-inch TFT showing the live values and NerdOS in your browser. Pool, worker and Bitcoin address are yours; you need no account and no cloud.

On the BM1373 the hash rate follows the clock directly. A higher clock needs more voltage, and together they produce more heat on a very small die. The stock cooler of the Gaia is designed for operation around 2.6 TH/s. Beyond that its 40 mm fan would have to spin ever faster to keep the chip in a safe range.

The AXP60 solves this with mass: the copper takes up the heat quickly, the two heat pipes spread it into the fin stack, and the 60 mm fan carries it away. That keeps a margin to the temperature limit, even when the chip works at a higher clock around the clock.

• Hash rate: around 3 instead of 2.6 TH/s, about 15 percent more from the same chip.
• Power: roughly 33 instead of 25 W. The extra performance costs some efficiency, about 11 instead of 10 J/TH.
• Cooling: 210 g of copper with two heat pipes and a 60 mm fan instead of the stock cooler with a 40 mm fan.
• Unchanged: board, BM1373, ESP32-S3, display, power supply and the browser interface.

If frugal mining is your priority, the Gaia is the right choice. The Gaia Copper Pro is for everyone who wants more out of the BM1373 without swapping the cooler themselves.

Running around the clock, the Gaia Copper Pro uses about 24 kWh a month, a good 6 kWh more than the Gaia. What that costs at your tariff and how hash rate and power compare is worked out by the mining calculator with your own figures.

The 33 W end up as heat in the room and need air. Stand the Gaia Copper Pro in the open, do not let the exhaust blow straight against a wall, and keep an eye on the chip temperature for the first few days. The copper cooler adds weight, so the Gaia Copper Pro belongs on a firm, level surface with its stand.

Every hash is a ticket in the same draw the large farms take part in. If your Gaia Copper Pro finds the matching block, the full reward of currently 3.125 BTC plus transaction fees goes to your own address, undivided and with no provider in between. The roughly 15 percent extra hash rate raises your chance by the same proportion; it does not change its order of magnitude. How small it is, is shown in the article on the odds of finding a block.

The Gaia Copper Pro is sold as a pre-order. Shipping starts on 7 November 2026, and orders go out in the order they were placed. You secure a unit from the first delivery, but you will have to wait until November for it.

Setup works like on any Nerdaxe: power, 2.4 GHz Wi-Fi and a browser are enough. The steps in detail are in the Nerdaxe setup guide.

For everyone who wants a compact single-chip device and more out of the BM1373 than the stock cooling allows. If you mine around the clock, you benefit from the margin to the temperature limit that the copper cooler creates.

It is less of a fit when every watt counts: then the Nerdaxe Gaia at around 10 J/TH is the more efficient choice. And if you want clearly more hash rate, you end up at the NerdQaxe++ with around 4.8 TH/s at roughly 80 W.

Around 3 TH/s, roughly 33 W, one BM1373 and 210 g of copper: the Gaia Copper Pro is the Gaia for everyone who wants more out of the chip without reaching for a screwdriver.
