Same here, mine should be here soon. Waiting on UPS to deliver.

Thanks guys, appreciate the help. Can't wait until this miner arrives!

The cable is absolutely fine, don't worry.

The miner consumes 1400w, which is 11.66A on 120v or 5.83A on 240v. The wires above are fine for the stated voltages. You can also get a 12GA wire which is rated for 20A, but they're less common.

Hey Dogie,

This takes me back to where I was confused in the first place. Bitmain says not to use a wire rated for less than 16A, but this cord would be 15A? Sorry if this was already addressed.

jr member have a lot of fan!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

The answer to that is provide both dba readings AND HQ audio recordings or video recordings so people can make the decision themselves.

Its often done when testing fans.

Thanks for those dba measurements.

Yes, the sound from S4 and SP10 are very different.  

Everything is bolted down or well connected with raches inside so more than likely, no more scary moment as DOA S2 that either didn't power on, or powers on but LCD doesn't come on.  LCD ribbon cable now even has really tight grip connection to the LCD pcb.  

Anyway, I will try to come up with more hands on data for you guys!!

Thanks to both as that does answer the question, in a back room with door closed should be ok. I work in the same room as 6 s3's and the noise isn't an issue but they are running in a cooled environment. I appreciate it.

What I mean is I can give a buyer two machines with identical dba readings. I can make one unbearable SP10 style, and one perfectly fine, but they will have the same reading. It makes the dba reading totally unsuitable for evaluating the quality of the noise generated.

Obviously someone asked for it so give it to them, I'm just giving my take on dba readings. And this is coming from someone who spend 16 hours a day 5m away from an SP10 for 4 months.

I don't think the mesurement is misleading. That is what the mesurement is.  Each person has different tolelance level.  Definately, it is not as loud as SP10 for sure, but it is a different type of noise.  It is not a high pitch like SP10 but it is a noise from the high speed fan and the PSU cooling.

The noise is difinitely more than S3 x 1.  May be a bit more than S3 x 3-4 units.  Its not a fair to compare against 1 S3 vs 1 S4.  Power consumption between these machines are more than 4x higher.

Members here wanted to know the reading and specifically asked for it, so I powered up my S4 and provided 2 different mesurements. (I did the same with S3 when it first came out.)  Not what I think cusotmer shoudl know, but I try to provide what customers want to know.

That decimal reading is from 1 unit, we may try with stack of a few units in a quiet place & will have an amp reading as well.


Side Note, I love my SP10 but I can't take the noise it make.  DBA reading wise, it is more than S4 and it is high pitch.  S4, yes, I don't want to be working next to it for 8 hours a day while it is hashing but it can be tolerated a bit more than SP10 noise.  (This is not a bedroom space heater option but it can be the space heater in the garage, or basement or in the spare bedroom where a bit of larger fan noise is not an issue)

That dba rating is why I stopped measuring in my reviews - they're misleading. 74 is very, very loud but at the same time you're saying its not much louder than an S3? And the video suggests not much louder than an S3 or an S2. I think its a lot more about sound quality than sound pressure. Some of my units are incredibly annoying but are 10 dba quieter apparently than others.

A bit more noise than S3...

Same as always did, one coupon for one unit

Thanks, appreciate it.

More info for S4...

To Power up S4, you have to hold a little nob (switch) on the PSU for 2-3 seconds.  Then it will power up.  Other wise, you may think it is a DOA like S2 used to be  

Video from Bitmain as more infomation regarding the S4.  I think this is easier than someone try to word how noisy it is

It push & Pull massive amount of air!!!

S4 does come with 2 server ears.  (There is NO POWER CORD included)  The box is well packed!!

If it was 4-5 months until you started to make a profit, people would be all over this.

S4 Noise Level (1 Meter Away)



============================

S4 Noise Level behind the S4 (back side of S4 where the fan push the air out of S4)

Wow that's an expensive machine... the power usage isn't that bad, but it's way too expensive. That's like 4-5 months to make a profit.  Mining is truly dead these days... damn what a shame.
