I guess with these high temps we can assume that the fans are as loud or even louder than the S7s

loud as the s-7  and I have one unit that squeals like a stuck pig.

I know there is a fix for that if anyone had a squealing s-7 and wants to post the fix please do so.

re-read my post https://bitcointalksearch.org/topic/m.15212835 for the edit about that... The effectiveness varies with fan speed but helped immensely here. Should apply to s7's as well.

They'll probably run even hotter at the default clockrate. I wouldn't be surprised to see miners breaking down in the summer heat. With these temps, you'd either have to underclock or replace the fans altogether- those temps will shorten the running time dramatically.

at what I paid for these  no oc until sept or oct.  I need to get back some money.

oh I am pretty sure these pull more juice then the s-7 when set to stock.

Disappointed that Bitmain shipped a miner clocked so high that it can't even manage it's default clock speed without high temps. Just more proof that their quality is going downhill fast...

Lol sorry, ninja edited 3 times. Perfectionist :c

My guess is we will mine at 600 to 625 with the s-9's until the fall  but no pressure at the moment to decide.

maybe simple box fans will cure all cooling as we only have 2 units with two on the way.

so once I realized miners were blowing hot air at the near wall I spun them around  this allows for okay temps

here they are blowing air  towards the far wall  about 70 ft


here are the avalon6's  I replaced.  you can see the grates below allow cool air to be pulled from below.

pointing the s-9 units towards the far side did get temps okay.

First time I turned them on I climbed dow nthe ladder knowing they were mining for bitmaintech.

Thanks for the effort and picts, phil.

Hmm, wonder if I could fit an English Wheel (metal panel forming tool) through the case to bow out the top-sink side? think think think...

I'll leave other to post pics. Got mine today and so far am - happy - with it but...
A. is so far averaging just over 13THs
B. A thermal design issue raises it head with these. The middle card and the one with long finned heatsinks facing the case wall run well over 4.3-.5 THs each. They report chip temps of around 90C. The one with the short fin topsinks facing the case is giving a bit over 3THs and reports the chip temp as banging around 99-100C. The air coming out of that card is also substantially warmer than the other 2. Will measure temps tomorrow sometime.

The root problem is that the short sinks are presenting a much high airflow resistance because the flow channel is restricted by them and the case wall. If somehow move the cards over a smig, hell even 1/8" might do it, then airflow should remarkably improve.

yes short term I down clocked from 650 to 625.

But UPS was late.
I had to dissemble the avalon6s from the array.
My sprained ankle from 65 days ago still hurts. ( bitch to be 59 it would have healed in under 10 days when I was 25-30)
The mining gear is in a loft with a ladder.

First time I turned them on I climbed down the ladder knowing they were mining for bitmaintech. So we went to the pc to check them and  setup kano.is

temps were very high   chips in the 90's






only 2 machines and a large loft  I was supposed to point miners in the direction in this photo
about 70 feet and an up draft fan in the center

edit: Also, mine wants to be a howler but I found a way to mitigate/highly reduce the siren effect: Put a square piece of open cell foam (air filter kind) over the grill of the intake fan. Suction will hold it fine but a touch of glue/tape whatever wouldn't hurt. Anywho -- it disrupts the airflow just enough that volia' howling gone.

Of course your mileage may vary Wink

we needed to get lower freq

but here are final setting on the 2 running

freq 625
fans at manual 70%

The one to be delivered here today looks like it was picked up late and sat for a while, so it probably won't arrive until Thursday. Tomorrow possible. Darn, and I was hoping to be the first one to post pictures.

Be patient just got back from solar array with setup.  2 units running. had to downclock just a bit.


photos to come.
