Zyber Blanc Review: BM1373 Desktop Solo Miner Tested at Stock Settings

First impression

This thing does not look like any other desktop miner I’ve had on my desk.

Most home miners still have the exposed open-air PCB look, which I’ve honestly gotten used to at this point. The Blanc is completely different. The aluminum base, acrylic shell, and mountain-style top cover make it feel like a polished consumer device instead of a bare development board. It looks like something you could see on a shelf at Best Buy or in an Apple Store.

That has been one of the things I’ve appreciated about TinyChipHub over the last couple of years. In my experience with their products, the craftsmanship has consistently been excellent, and the Blanc is probably their most finished-looking miner yet.

Shipping and packaging

The Blanc arrived in 7 days, and the packaging was excellent.

The unit came packed in a way that felt intentional, not like a miner dropped into a box with foam around it. The inner packaging, the ribbon lift, the protected shell, and the way the miner sits inside the box all make it feel more like opening a finished consumer product than unpacking a hobby mining board.

That may not affect hashrate, but it absolutely affects the first impression. TinyChipHub did a really nice job here.

Design and build

The Blanc has a full aluminum base with a detachable top cover and acrylic shell. The top cover gives it that mountain-style look, but it is not just there for looks. The miner uses a closed air duct design with dual intake/exhaust fans, and the top cover is part of that airflow design.

The way the LEDs shine through the mountain-shaped cover is one of the nicer design touches. Instead of staring at an exposed board, the Blanc gives you a quick visual status through the top cover: red for startup or hardware detection, yellow while it is connecting to WiFi or searching for the network, and purple when it is connected to the mining pool and running normally. It makes the miner feel more like a finished desktop object than a bare electronics project sitting on a shelf.

Setup

The Blanc does not have a built-in screen or display like most other miners in this class. You can pair it with TinyChipHub’s WatchDog device, which I’ll cover separately later, but for the initial setup I honestly did not miss the display at all.

Setup was extremely easy.

I powered it on, joined the Blanc’s WiFi network, entered my WiFi and mining settings, rebooted it, and then opened the assigned IP address in my browser. That was it.

No screen was needed. No weird workaround. No hunting through logs. Once it joined my network, I was in ZyberOS from the browser.

ZyberOS

ZyberOS looks very clean. The dashboard is easy to read, and it has the standard metrics and controls I’m used to seeing: hashrate, power, efficiency, temperatures, fan speed, shares, pool settings, performance modes, logs, firmware updates, and restart options.

It feels familiar, but with more polish. Nothing about the layout got in my way, and I was able to get in, set the miner up, check the numbers, and move around the interface without needing to think about it.

Test settings

For this first run, I tested the Blanc at stock settings.

The only changes I made were to the fan profile. I set the minimum fan speed to 40% and the target temperature to 60°C because I wanted to keep it nice and quiet.

That is important context because these numbers are not from an aggressive overclock or a loud fan profile. This is basically how I would run it on a desk.

Performance results

After a little over 15 hours of uptime, the Blanc settled in right around 2.43 TH/s while pulling about 23 watts, which worked out to 9.44 J/TH on the dashboard.

That puts my unit right in the advertised 8–10 J/TH efficiency range, while running quietly and staying under the 60°C target temp I set.

During the run, power stayed in the low-23-watt range while hashrate held close to the expected 2.4 TH/s range. The share stats were also clean, with 15,067 accepted and only 3 rejected.

For a small desktop solo miner, those are very strong numbers.

Noise and thermals

The Blanc was also quieter than I expected.

With the fan minimum set to 40% and the target temp set to 60°C, it held the ASIC around 55–56°C and the VR temp around 54°C. The fan sat around 42% during the run.

For this first run, that is what I wanted to see. I was not trying to push the chip or test the limits yet. I wanted to see how it behaved at stock settings with a quiet fan profile, and it stayed stable, cool, and quiet enough for normal desktop use.

Scoreboard

ZyberOS also includes a Scoreboard page, which shows recent share difficulty results. My best difficulty during this run was about 4.9B, with other notable shares showing up in the hundreds of millions.

This is not something every miner dashboard includes, and I like having it there. For solo miners especially, best share tracking is part of the fun. No, it does not mean you are “closer” to finding a block, but it is still one of the things most of us like watching.

Final thoughts

The Zyber Blanc is not just another bare-board desktop miner.

At stock settings, mine is doing real 2.4 TH/s-class performance at around 23 watts, with efficiency under 10 J/TH. It arrived in 7 days, the packaging was excellent, setup was simple, and the build quality is unlike anything else I’ve used in this class.

The biggest compliment I can give the Blanc is that it feels like a finished product. A lot of home miners still feel like hobby boards, even when they perform well. The Blanc feels like TinyChipHub is pushing this category toward something more polished, more desk-friendly, and more consumer-ready.

This also makes me excited to see where the Zyber line goes next. If this is what they are doing with a single-chip BM1373 miner, I am very interested to see the larger multi-chip Zyber units that I would expect to come down the road.

Based on this first run, they aced the assignment.
