Is a liquid cooling system better than air-cooled?

Efficient liquid cooling is the main advantage of Comino OTTO, compared with similar systems. Specially designed, calculated and manufactured full cover copper water blocks are made for OTTO to cool all the crucial components and ensure hardware stability: GPU, Video memory, VRM modules on motherboard and video card, CPU, South bridge and m.2 SSD storage.The device stays cool, operates better and longer. OTTO performs well under intense, prolonged workloads, such as gaming, rendering and others. The device stays cool even at room temperatures of 95°F, operates better and longer.

How loud is Comino Otto?

The noise level of this product is 40 dB in the office and below 32dB at home.

Can I upgrade ОТТО in future?

Yes, you can. ОТТО is manufactured in a way that lets you configure and place standard components inside provided that they are compatible with each other.

What coolant is used in OTTO? Do I need to renew it from time to time?

OTTO coolant is a pure H2O + anti-corrosion additives. Otto is designed to operate maintenance-free for one year, however, if the liquid level decreases significantly for some reason, it is advised to fill it to the level.

Can I have OTTO with color coolant?

We ship OTTO with a colorless coolant by default. However, we can fill OTTO with any coolant color you want: clear or matte. We have recently done research in our lab and found that coolant paint clogs the edges of fittings and the water block, and reduces the cooling performance after 6 months of usage. This is why we recommend a clear liquid.

What Comino devices can be used for?

‍

How much heat does the device produce? How can I know whether this is a lot or not?

The device produces approx 1 kW/h (depending on the settings), this amount of heat is enough to heat 10-20 sq.m of living apartment.

How much electricity do your devices consume?

If we consider Comino N1, it consumes 0.715 - 1 kW (±5%)

Comino Grando DECRYPTUM PR P104/12 4U consumes 2.7 kW (±5%)

Сomino Grando Rack consumes 25 kW - 50kW

‍

Will my room turn into a sauna?

Comino N1 dissipates approximately 1 kW into the air, blowing out a stream of air at a temperature about 20°C, relative to room temperature. For example, in quiet operation mode, when the room is 25°C, Comino blows air at a temperature of 45°C, and the temperature of the GPU is about 55°C. Naturally, if there is no ventilation, then the temperature in the room will gradually increase.Moreover, our B2B product Comino Grando can dissipate up to 3.5 kW of heat at the delta temperature of 20°C received from the water blocks.

Is it possible to connect the device to the house water system?

Not yet, but we are working on this function.

Is there a Wi-Fi option?

Yep, sure.

What are the size and weight of Comino N1?

The height, length and width of the device are 63.5 cm, 45.9 cm and 17.5 cm, respectively, that allows you to easily place it in an unoccupied corner of the room and forget about it while it mines the cryptocurrency for you. Read more on ihodl.com. The weight of the device is 27 kg.

Does it work when it's humid?

Yes. Relative humidity should not exceed 80% (without condensation). Comino is a super-computer, so its operating conditions are exactly the same as those for other equipment.

At what temperatures does the device work normally?

Normal conditions typical for stationary equipment operating in enclosed spaces at a temperature of +2...+45°С, relative humidity up to 80% (without condensation) and atmospheric pressure 720...780 mm Hg.Art. To increase the life of the device, we strongly do not advise to operate it at an ambient temperature higher than +40°C and humidity more than 80%. The integrated cooling control system will not allow the devices to be operated at negative temperatures and temperatures above +45°C.

What about warranty and lifetime?

In case of timely maintenance and normal operating conditions (up to +23-25°С and humidity not exceeding 80%), the guarantee is 1 year. Lifetime is unlimited.

Is it possible to install my software inside Comino?

Yes, it is possible. It is necessary to connect a hard drive (SATA) and a monitor (to the built-in video card), install an OS (for example, Windows) and necessary software, then use Comino as a normal PC. In this mode, the display will not show temperature information, but we are working on it.

When ETH switches to POS, how can I use Comino? / What happens when ETH goes POS?

If Ethereum switches to POS, then it will be possible to continue mining a wide range of other altcoins via Comino and use it for tasks solved on GPU accelerators.

Can I change the video cards myself?

Yes, it is possible, but the cooling system is designed the way to install only boards of the particular reference (standard size or model). This additionally needs to be figured out. Installation should be carried out only if the special instructions are observed (provided on request).

Can I sell cards if they become obsolete?

This question relates to the market, which will be actual that time, we do not make forecasts.

What the hashrate is?

For Ethereum hashrate is 200(±7%) Mh/s*. For ZCash hashrate is 2740.0 sol/s (Equihash).

What is the device noise level?

The noise from Comino is about 30 dB - it's quieter than a whisper. Noise is one of the problems that we successfully solved via liquid cooling.

Do you update the machine at all after a longer time? The software?

We update the software periodically to increase the functionality of Comino.

Is that possible to dual-mine?

Not yet. We do not plan to provide this function in the nearest future, as this may adversely affect the equipment.

‍

How much dust does the device collect?

Due to the high efficiency of the liquid cooling system, the volume of air circulating through Comino is significantly less than through the classic mining farm, so it collects much less dust. Most of this dust settles on the liquid radiator, which is easy to clean during maintenance.

What is Comino's efficiency?

In general, the efficiency of computer technology is very small - less than 20%, all the rest is parasitic heat, which Comino transforms into a useful work of heating the room, therefore, conditionally, we can say that the Comino's efficiency is 100%.

How many ETH and ZCash per month on average can I get on one COMINO?

This parameter changes daily, it is more convenient to follow it on the www.whattomine.com or to wait for a calculator which'll appear soon on our web.

How quickly will Comino pay off? How can this be calculated?

To calculate it please use the calculator via the link Ethereum Mining Profitablity Calculator

What is the recommended type of power supply? Is a separate power supply needed?

Comino is a plug-n-play device, its power supply is already inside.

What is the recommended internet connection to use with the miners? Is regular DSL wifi connection ok, or is cable internet or other high-speed connection needed?

Either LAN or WiFi will work fine. For the best performance, please, ensure the bandwidth of the channel not less than 256 kbit/sec.

What differs Comino from other miners?

This is a very broad issue. The difference from the handicraft GPU miners is revealed in the paragraph about the price. Our unique selling points are:

liquid cooling system, which allows the device to work 24/7 in the increased acceleration mode, effectively removing heat from video cards. This can not be achieved through air cooling
plug and play device
very quiet
very small. We have a special arrangement of the device in which the video cards stand alone. As a result, Comino is 5 times smaller than an ordinary mining farm with the same performance

What nozzle do I need to remove the case cover?

Т20Н will be a perfect match.

Can I regulate the heat release? What shall I do in summer?

Thanks to the Power Limit function, you can regulate the heat generation in the range from 750 to 1100 V/h without loss of performance (in case of ETH mining).

What cryptocurrencies can Comino mine right now?

Comino can mine a huge amount of alt coins, such as ETH, ETC, VEO, BTM, LTC, MSR and 400+ more. To switch from one currency to another you need to change the wallet and Comino will start mining the chosen currency automatically.
