[b]Here is a link to the video to see the silencing and cooling experiment.[/b]

What do you guys think?

silencer Antminer s9 fan shrouding experiment soundproofing test video. I am using my Antminer s9 as the asic miner for this experiment . Antminer cooling s9 with 4 inch fan shrouds and the custom minerdigi dual exhaust shrouds, see the test video.

I am donating my antminer s9 to the name of science for this experiment. we are testing the difference of the fan shrouding that are commonly used on the antminer s9 for cooling then or attaching ducting. We are using an antminer s9 cooling fan shroud that is 4 inches, an antminer s9 cooling fan shroud that is 5 inches and an antminer s9 cooling fan shroud that is 6 inches to (2) 3 inches outputs if you don't have room for 4 -6 inch ducting to cool you basic miner. We are using the antminer s9 for our asic miner cooling setup obviously.

Comment what you think the next video should be and or some cool new designs we can try!!!!

All ventilation systems have five functional components: an inlet, an outlet, a driving force,

distribution and a path. 1) The inlet provides a location or locations for air to enter the

space. 2) The outlet provides the location for air to leave the space. 3) The driving force

provides the means to move air into, through, and out of the space. 4) Distribution defines

how air moves through the space. 5) The path must exist so that air can enter the facility, go

through the inlet, pass through the space, leave through the outlet, and finally exit the

facility. If all five functional components exist and are operating properly, the ventilation system

probably is working for the given conditions. Solutions to most

ventilation problems are found by identifying which functional component(s) is missing or

improperly operating.

COMPONENTS

Fans serve as the outlet and driving force in the mechanical ventilation systems in mining farms. The inlets are often a cooled air or some other inlet components.

Distribution is created by the placement of the inlets. Air in an mining facility follows a path from

the outside, through the inlet cool cell or other inlet components, under/below

the space and, finally, out the fans. Understanding the path air takes and how the path

interacts with the driving force helps ensure a well-designed and fully-operating mining

ventilation system.

STATIC PRESSURE

Static pressure is used to evaluate the amount of impact various ventilation system components

have on the airflow path within a given system. For mechanical ventilation systems, the fans

create positive static pressure to move air through a given system. All other components create

negative static pressure that causes resistance to air moving through a system. A mechanical

ventilation system operates with the static pressure in balance. The positive static pressure

created by the fans equals the negative static pressure created by resistance as air navigates

obstacles in the ventilation path.

CONCLUSION

• Fans of the same diameter are not all created equal. Airflow capacity at different static

pressures varies depending upon fan make and model.

• Increasing the static pressure a fan must operate against reduces the amount of airflow

delivered by fan.

• The fan blades are over 4 inches causing extreme static pressure resistance even without adding the cubic feet of area in the ducting.
