No UPS option this time either, which never gave me problems.
Fedex would give me problems.
Plus asking for SSN and such on the order page, never asked me about that before.

Ok. But how bitmain can verify if given SSN is good?
This is an useful request


this is FEDEX req, not bitmain's, on orders $2500 and above. basically, if you order 2 or more.
Only order one at a time or customs will ding you.

The front was a Delta QFR1212GHE 12v 2.70A and the rear only had the markings "JSL" but no model number or even direction of flow.

A piece of additional info. Even though ive swapped them out for different ones the rear fan is still 120rpm faster than the front. Front 1800rpm - Rear 1920rpm set at 25% speed

S9 now on sale on Bitmain store front...

...this time no notification on twitter!!!
strange behaviour.
why they do not spread the news this time?

mmmmmmmmmmmmmm....

They probably have a limited quantity.  Notice that they also have a single miner for sale...

I am with you on the mmmmmm.

interestingly, there are no specs so far.
i think that these are 14th (b23) that did not quite make it to 14Th.

I have a question: i have one S9 that has much higher speed fan on the back than in front.
Bitmain says that fan in front is up to 6000rpm, and back one up to 4000rpm, but i have it backwards and that miner is actually running a bit hotter.
Does anybody think that it is worth reversing the fans? Miner is in hosting, so i cannot visually inspect the fans.
Can someone confirm that front and back fans are actually different (model, appearance, etc)?
Or is it possible that bitmain simply connected fans to the wrong connectors, unlikely as it is.
thanks.

My second hand 11.85th S9 had these fans on before I swapped them both out. Back one would run faster (and whine) than the front. In the picture the left fan is front and right fan was rear:-

Hope this helps some

great, this helps so much, big thanks!
It seems that you also had higher speed on the back fan, which should not be happening according to specs.
I will try to ascertain if they simply misplaced the fans (put them backwards: back in front, etc).
When you swapped them, where did you get replacements: from Bitmain or elsewhere?

What a deal at 1445+shipping for 13.5 TH, even with free power thats over 5.5 months but with Diff looking like its on the up swing, more like 7-8 months for ROI with FREE POWER. Good luck with that, I have 20 S7's that I have started selling off and down to 8 left. Time to cash in and just buy BTC and hold. Maybe I'll keep one for heat this winter, actually doing better with GPU's and HW is always worth something when done with it.

You were right, just takes much longer than I expected to boot up fully.
Though on the new autoset firmware, even 20 minutes still didn't connect.
Rolled back for now.

Still at 5.6th?

Up to around 7-8TH
Looks like I lost one of the three boards?

I think that they stopped showing batches even before.
One thing of note: UPS is absent from delivery options and there is a big red sign showing during ordering saying that they should have your EN/SSN number on file if cost is above $2500.

EDIT: blockchain wallet asked me to reduce the fee and I listened, foolishly. It promised confirmation in 1 block and now 2-4 blocks and no confirm. Now i would have to wait for bitmain's rigamarole. Oh, well.

S9 now on sale on Bitmain store front...
And no mention of Batch number. How very weird. Even the s2's had batch numbers, wonder why the change?

I have a batch 23 S9.
What should I expect the board temperatures to read? The miner status page reads 87, 84 and 101. One board is consistently hotter. Any concerns?
The board temps seem to change if I power down and restart, where other boards become consistently hotter / colder and generally stay that way until the next time I power cycle. Seems like odd behavior to me, but I assume it has something to do with the firmware.

Also is there an ideal temperature for hashrate or for long life?
Thx
Temps look perfectly normal.
With the auto-tune firmware Bitmain has used since batch-16 there is nothing we as users can do anymore to change hashrate or temps.
