New manufacturers of Bitcoin ASIC miners are coming out and usually CCN has already heard of them and written something or another. BitCrane surprised me by coming out with the BitCrane T-110 Bitcoin ASIC miner. Not only did they burst on the scene like that, causing people to email and message me asking if BitCrane was a scam or legit, but they also surprised us all with a new innovative cooling system. I contacted BitCrane, and they quickly got back to me. The T-110 is a well engineered piece of machinery with top of the line components. The water cooling system is a surprise addition to the unit as many that go for liquid cooling are usually for large farm immersion cooling systems. This all in one system is complete and setup very well to handle the shipping rattles and the constant use it will get mining.

As you can see, the specs are very nice and the cooling system is a solid addition. The T-110 was shipped in a securely packed box. The shipping gods did not disappoint and after giving it a careful check, due to it being liquid cooled, I plugged it in and turned it on for a leak test. No leaks and all was good after 1/2 hour. From there I plugged it into the network and logged into the interface. The ip to log into the user interface is on the front of the case, 192.168.1.140. First thing you will notice is a simple interface that is very easily navigated. The layout is quite excellent with a BitCrane skin that adds a slick look that is lacking on many other interfaces. As we all know though, interfaces are not about looks. The status portion of the page gives a detailed look at your temperatures as well as your accepted and rejected share counts. Just below your status page is your pool selection page. You can add three pools as it is good to have backups. One main pool and two failover pools. The last section is your network settings panel. Here you can change the default ip and other settings to better interact with your own network as needed. All in all, it is a simple yet effective interface. It allows those new to Bitcoin mining to take the miner out of the box and start mining.
For this review, I used BTC Guild and NastyPool as my pool choices. Poolside, the T-110 averaged 1.1 to 1.2 th/s and showed within 50 gh/s of said measurements on the control panel display. The BitCrane is a very stable ASIC miner: I did not have many fluctuations at all. Temps ranged between 82c to 100c at ambient temps of 32c to 45c on my mining bench. The T-110 pulled an average of 960 watts at the wall. The T-110 is a bit louder than some miners but not one of the banshees; it registers 66 dB at 4 feet. Despite the liquid cooling system, the fans run at the same speed 100% of the time. The unit has two boards that house the chips and each one is fully liquid cooled. The fans pull the air in and blast it out each side. One of BitCrane’s selling points is they are easily stack-able and that certainly holds true here. The case is very sturdy and with the custom self-contained PSU you can stack up to 4 of these safely and not have to worry about any wires other than the ethernet and power cables both on the back of the unit. This setup allows for simple setup and administration.
BitCrane has put together an excellent miner. Overall its ease of use and relative power make it an excellent ASIC Bitcoin miner. The T-110’s ability to be stacked four units high allows for easy growth as well while taking up less space than many miners in its speed class. The water cooling system, which on one hand makes me have to worry about leaks, was perfectly functional. The hoses were top quality, and closed loop system normally has fewer points of failure and was used well in this application. No reservoirs and extra tubing.
The BitCrane T-110 can work well in large installations but having the hot air exit from both sides can be problematic in farms that use a hot and cold isle. They are a good fit for climate controlled data centers or for home users who will not be running several hundred of them.
BitCrane has aimed for making fast, simple to use miners that can be used in many environments. They have done just that with the T-110. I look forward to their next gen units as well. I was able to interview the CEO of BitCrane James Tsuei and I will publish that soon. BitCrane is not stopping with the T-110, they are set to roll out more miners that are both faster and more versatile. With their solid belief that mining should still be decentralized they are getting miners out that will allow more and more people to mine. To those that are worried, BitCrane is not a scam they are the real deal and have a well setup company and team. :-)
Disclosure: BitCrane provided the T-110 at a discount for review
