Batch 12 just showed up for $665!!! This will hurt resell value of our units. They should have end it at batch 11. Sad

Amazing thing is that in the UK people are still selling these on ebay at £1200 ($1600)...

Rich

well there is vat and import duty so a 665 + 55 shipping = 720 and 30%? = 940 still a very big markup

940 vs 1600

at this price of 665 .

I may get 4 more for my clients.

There is no import duty, only VAT.

Noticed Bitmain removed the reference to being able to use coupons given before Chinese New Year? Sucks. Was ready to order 15-20 more but I guess I might hold off on that.

while I would have wanted to use them and surely purchased more why do they do this?

I find it insulting. Plus disrespectful to their customers.

So if they did not do it I would have most likely have placed my order for 4 more units. Now if I do that I feel I would be cheated 0.20 btc.

Which would be easier to do if they had ever paid my compensation for my batch one.

Well I will think about what to do . Meanwhile I will mine a bit more.

well its been about an hour on my new s7.. temps are 56, 59, and 57. its running at stock 700..
i was going to underclock it and try to use the one 1300W psu, but i decided to run it full speed and use a 750W psu to power one of the boards instead.

it makes a wind tunnel noise, kind of hollow sounding... its nice that i fixed the howling fan, sucks i might have to get a new fan when i start up my s5 again.

i wonder if i stick some foam padding on the outside if it will quiet down the hollow sounding.
or maybe a foam padded box with fan holes. maybe just cut holes in the box it came in. if i cut the box in a H pattern i can fold in the tabs and use those as air ducts..

i saw the one post where the guy put it in a air duct.. but i dunno about that. those ducts are expensive.

The ducts are sometimes expensive but not always. You can try using a pwm fan from noctua and using that, but the cfm from those is a bit on the low side and s7s tend to not like those fans. They run real hot with those but if you hate heat, dont use em.Ducts are cheap and work well. Bitmain didn't work on cooling very well.. considering s7s are nearly the same size as s5s and s3s. They still have a good miner, but they might want to think about cooling for their future miners.
S7s under and overclock very well, so if you wanted to do that to make it quieter, it works.

the s7 fan is 4500 RPM, the s5 fan is 4100 RPM and i have 2 AFB1212SHE fans that are 3800 RPM and i also have a TFC1212DE fan that spins at 5800 RPM.. altho that thing is loud enough to hear outside through the walls. and a few s3 fans not sure what the max speed those are.. they never got above 2000 RPM in the s3.

tomorrow i am going to play around and see if i can find a good combo.

with the enclosed case, and the high static 4400 rpm fans i think its causing a lot of pressure, causing the air to make the noise.
it kind of looks like they didnt do any kind of research at all trying to see what would work best.. if you can get the air to flow better it might even cool them off better.

might even run to frys to get a cheap 4.99 120mm fan to break the insides out and use as a spacer to see if that helps.

i did already notice that fan 3 slows down at a steeper curve then fan 1, so maybe if i can split the fans with a Y cable and run them at the same speed instead of one slower then other it might help

first set fans manually to 50%

70% is top speed.

50% should drop to about 3700 rpm

check your temps at 50% you should be lower then 65C. this is free to try .

ok so with the s7 fans, i did add a fan guard to the rear one from my s3.
i set the fans to 50% and the speed to 650..
this gives me an ok sound, with temps of 52,55,53.

ill live with this for now.

the speed of the fans are 3720.

you have a pm about that psu for the s5.

will get back to you on psu I have this one

http://www.amazon.com/EVGA-SuperNOVA-PLATINUM-Crossfire-220-PS-1000-V1/dp/B00SOXNK52/ref=sr_1_3?

need to check it for shipping as we are east to west coast

Im convinced now Bitmain doesnt give 2 shits about the customers. Between the HUGE lack of customer service and them totally killing the potential resale value these pieces of metal once held. Oh and selling used miners with burn marks.......but what would one expect from a chinese company thats unregulated.

ok so i got my s7 today, set it all up..
holy crap, it whistles.. so loud.. im guessing because the front fan is pushing more air then the rear fan can expel and air is coming out all of the holes on the top.. so annoying ;(

if i put my hand infront of the rear fan it stops.. im guessing because the air pressure makes the rear fan speed up.. i kind of dont want to put something in front of the fan.. any ideas? maybe if i take the rear fan off and put a washer or something making a small space behind the fan and the case?

Someone put a small piece of cardboard in a corner and it made it stop, might want to check that out before you try to figure out something more complex.

i put my s5 fan on it. no more howling.. maybe the fan has a bad bearing or something.. it was super hot.

unfortunately i need another psu to power my s5, so ill know when i fire up my s5 and the fan howls.

not sure if bitmain will warranty the fan.. im definitely not going to send this one to china for them to test it.

that might work, i got some tape ill try it real quick.

without the whistle its actually quieter then a s5

hmm also something isnt right with speed 600.. by default its 700.. i lowered it down to 625 and it was 4.1ths, went down to 600 and its only 1.8ths..

For some reason you have a board that doesnt like that low or something. Did you try a power cycle reboot to 600?

This is a pretty stupid response if you ask me especially since their Batch 12 pages said we can still use coupons offered before Chinese New Years which is the ones I have. Fortunately I was able to donate many of them before they expired.

Hello Support,

My S7 coupon although says expires March 2nd. The update on Batch 12 says that all coupons before Chinese New years are still valid. My coupons for .05 discount was from before Chinese New Years. How come I can't apply them to my order? Please advise as I'm ready to order 7 more units.

thanks,

Why is everybody saying PEERCOIN is up? It seems to be the same price as it was before. Its just as profitable as BTC.

People are just confused. It occasionally rises up over bitcoin, but it's generally unstable and not a good coin to mine. I'm guessing this is being fed by coinwarz.com. They're not the best source for market price but everybody seems to look at them for information. They're wrong most of the time, though.
Possibly somebody bumped market price, I dont know but i'll look into it tomorrow when I have time.

peercoin is a better buy and hold coin then a mine and hold coin.
