Nope, it's a clone. It replicated BTC in every core angle. None BTC is called ALTCOINS.

And don't be naive thinking BCH was created to increase block size. It's about making money. Are you forgetting all agreed and lock in for Segwit? Then few days before 1st August, ViaBTC and Bitmain decides to fork?

Aren't Segwit 2x fix those problems?

Demands is not more than crazy frantic buying by S. Korean, not elsewhere.

Let see how this war pans out between real Bitcoin vs clone.

i asked around only youngsters know other coins besides bitcoins.
oldfags who never bought them only know bitcoin

u cant replace BTC's position so easily.

with proper ducting, sound insulation foam around the machine can reduce noise significantly

agree..
i haven't got my miner yet but just roughly come up with the design of the box and the materials to be used.
actually can DIY using those MDF 3 tier box with doors.  have to drill 2 holes, stick some foam and sound dampener material...  towel in between  biggrin.gif

I got sell miner fans.
the other day I change to other models with smaller motor size, my customer feedback to me that his temperature dropped 10°C.
the standard issue fan motor size is too big n covered whole middle area.

then I realized there's a blind spot due to the fan motor size.
see when I'm free will change the mining cooling system to duct 15cm fan blow into 12cm hole to give 100% coverage.

just need to cover the fan frame and miner aluminium frame with foam can d

By that.  I believe 4 small fans work better than just 1 big fan.

fr3ker

these are the size comparison and temperature performance after changing the default fan.
the default fan motor size is too big and caused a blindspot which is prone to overheat

How many DB less noise?  laugh.gif

i dont have dB meter to measure, but it's much better on the ear because nidec motor is more towards humming low pitch than delta high pitch EEEEEEEEEEEE that kind of noise.....

Nidec is 60dB while default delta is 66dB

Just a random thought, maybe try to create a certain distance between the intake fan and chasis? I'm just sharing random thought.

bigger fan pass through a adapter blow air in, then exhaust fan another same size shroud bug distanced a few cm away.

or a big snail shape blower will do (but dunno blower will last 24/7 usage or not

That just gave me a thought, using white PVC pipe to create 140mm to 120mm adapter for intake, length maybe 6"-12", then use a good 140mm fan, it should squeeze into 120mm and and reduce the hotspot.

cant be so far away, lose pressure

I see. thanks.

basically for small volume trading, as long as price increase/decrease for more than 1% I can turn a profit la kan?
what about large volume?
*
there is also price slippage.
when u hit sell, others might be selling same time.
so u ended up selling lower than what u aim to if the buyer is too small

It's few pages back, do search
It's called Nidec.
Newer batches of L3 & D3 is using this fan, single sided only, on most cases is the exhaust part, not intake.

U need to R&D, which fan on which miners.
*
I got a customer he open the other side.
dunno what brand YS fan and some blue colour label unknown china fan.
rpm dropped after 1 month usage.

one side put good, the other side put shitty fan.
