I got my batch 7 online yesterday and the noise is horrible and I used to think S5 is noisy.
Fans run over 4000rpm and blades are about 50C, air is traveling too fast, screams and resonates badly.
3 x DPS-600 powers take 1400W from wall, I tested power draw upto 1600W.

Customs took 1BTC for sale tax but I have "free" electrics as garage is heated with S7 so I maybe ROI some day.

What did you really expect? One S5 with one jet blaster fan was horrible noise pollution. Then, an S7 with two of them running. The temps aren't even the "real" temps. It's just a temp sensor on the board somewhere. I would always add 10 degrees to the temp shown.

Are there any suggestions for replacement fans? Just in case one is broken or they are too loud?
Greetings,
me

I have several brand new S7 fans. $25. US. PM if interested.

if voltage controller be in new boards. i think we can not control them

because pic12f1822 job is simple; adjust voltage at boot and set working voltage to buck controller ic. this is chip protection for them.

If there is voltage control.... a way will be found to adjust it.

Rich

There's a voltage listing in /config/cgminer.conf on S7's. As someone mentioned earlier, the "factory defaults" are not the ones all miners come with though. Factory listing with 700 mhz is 0725, the one in some config files you'll see at receipt is 0706.

It looks like this:

"bitmain-voltage" : "0725"

thats very good. we know its adjustable now. thanx

Has anyone experimented with tweaking clock and voltage on various batch units? I have Batch 1 and Batch 7 and I notice just changing the clock on batch 1 pretty much does nothing so it obviously needs more voltage to support it. I may try to SSH into my batch 7 with same chip number and see the difference in voltage settings and try to test the B7 Settings on a B1 unit

OK let's not get carried away here. We know that Batches 1 to 5 and 7, the 162 chip Systems, are a straight string design and are not voltage adjustable except by varying the Supply Voltage. Any Voltage numbers in the /config/cgminer.conf are merely a leftover from previous miners that were adjustable and will do nothing if changed.

The Miners that might be adjustable are the 135 Chip Batch 6 & 8. However although we suspect there might be a Buck Controller this is not yet confirmed. If there is one then it might have a fixed voltage like S1 & S3. Or if we get very lucky it might be software voltage adjustable. Bitmain might make this directly adjustable from within the GUI like S4 or it may need the cgminer.conf to be edited.

All of these questions will be easy to answer when we can get a picture of the Batch 6/8 Hash Board and if there is a software controllable Buck Converter people can then explore play with the cgminer.conf setting.

Yup. Typical Chinese customer service... Lol

I don't think we're getting anything back. What pisses me off more is they have the $150 coupons away in a heartbeat a week or two ago to that other batch......

No problem with gripes about lack of compensation. No problem with that at all. However, "ethnicity" has nothing to do with one's "character." So, please refrain from using the word "Chinese" as though all "Chinese" have no "character." I know "Chinese" individuals personally who are good people with tons of honor and character. In fact, I know Chinese who have more honor and character than many westerners.

EDIT:
As for compensation; I'm going to be patient and give it a bit more time to see what happens. Yes, go ahead and tell me, "Don't hold your breath." That won't keep me from having patience. Let's see if Bitmain will have honor and character regarding their "word" about compensation. They did not say "when" there will be compensation. I'm just going to remain patient and see what happens.

I don't think Brown nosing will get you comps much.

Considering I've spent quite a bit of time in Asia and China in particular, I can openly repeat what I said above and give the middle finger to political correctness.

It is TYPICAL customer service over there to treat ppl like they are. Seen it tons of times and had it happen to me enough to know. I already wrote off any compensation from them but still gives us the right to grips and tell everyone we know. Lolol.

i think you are right , new boards with coils have a buck converter, because i seen ICSP like 6 pin socket on bitmains picture. this means have a microchip pic for voltage controller like s4. another side of pcb must to have 2 or 4 big mosfet + buck controller ic + microchip pic.

edited old msg:
also i am thinking what is 1385+BIN2 label on v2.0 boards. Huh 1385Gh binary v2 Huh if chips have any eeprom we fucked up folks. this means hash count is true. if 1385 not hash number or freq, meaning bm1385, so why labeled 1385 ? all S7's have not bm1385 ??

or maybe this is not bm1385, this is different new chip bm1385+ pffffffffffffffff Angry

Yes could be ICSP connections, did not realise the S4 used a Pic to control the voltage, assumed it had a programmable VRM?

On the 1385+BIN2 that could imply that they are speed / voltage selecting the BM1385 chips and these were from Bin 2?

Final observation

from a much better picture of the chip side of the board is that they have fitted an oscillator to every node on the Board. The S5 originally had a single oscillator, then on the V1.91 they fitted an oscillator for every 4 Nodes on the board (I still suspect this is one of the changes that enabled the S5 to be successfully undervolted), however the board layout actually had provision for an oscillator on every node.

It would be great if the 135 chip boards turn out to have a programmable voltage Buck Controller...

Rich

i seen bin2 from this picture :
https://ip.bitcointalk.org/?u=http%3A%2F%2Fi.imgur.com%2FkrFSsnV.jpg&t=559&c=Dovh_zqjP3lwJw

bm1384 chips voltages at own corners, bm1385 feeding left and right, my picture is 4.86 S7 (i dont know which batch is probably B3) but boards version is 1.8 pcb version is 1.6

if voltage controller be in new boards. i think we can not control them

I believe I'm doing what you are doing to inspect the rigs from now on with future batches. Especially, after reading the WARNING here in the photo you provided.

Thanks for sharing...

Interesting for sure. I like that they gave customer permission to open it and check. That is much better then the don't touch policy.

Maybe they are changing for the better on warranty... or maybe to many were falling off. Makes me wonder on number for them to send that letter with it.
