under clock it to 550 and set fan to 90% and see the temps.
Push up the freq once you are comfortable with the temps.
My S5 is under clocked to just under 995Gh @ 56C in the same room as the S7-F1
Topic: New one fan S7 - page 2. (Read 9869 times)
or should I look at also buying the second fan option from bitmain and either wait 90 days before voiding warranty in the meantime underclock to maintain safe temps?
As Midwesterners we are moving into AC season so we should be able to correlate the season transition as far as s7 temps vs. ambient temp. I have an s5 running with a box fan blowing air at the miner and pushing most of heat out of room where there is open window exchanging ambient air in/out. with outside temps 75-80 F the s5 temps are 49 -53 C. I also have an s3+ OC running along side with temps 38 - 42 C. What I am saying is the s7 f1 should be similar to stock s5 with my setup moving into AC season I am wondering what to temps to expect from a s7 f1 with ambient temps maintained 75-80 F. With the s5 we strove to keep happy under 65, and I'm well under that so if I get an s7 f1 and achieve under 70 is that baseline to seek?
I have read in this very thread that they can run up to 80C. Not recommended for long periods.
Mined did run into the low 80s for a few hours. i quickly dropped it down from 700mhz to 650mhz. that dropped the temps to 70C.
On Average I am running them at 64-68C @ 80% fan speed.
Weekends they run @ 64C @ 90% fan speed.

Has anyone else recorded any temperature differences between the F1 and F2 batches?
Or, has anyone ran one hard, overclocked, and checked heatsink material and bonding?
Southern Mid-West summers are brutal. Even though I will be experimenting with a swamp cooler this year, I cannot handle something which I know is going to run 10 degrees hotter.

is it acceptable to run the s7 at 71 C? I am trying to sift through the main s7 thread but it is over 400 pages and is going take some time, so please excuse my possibly already asked questions. I'm not completely through the s5 threads and though different miners it seems concesus to keep under 65.
You will need 10 PCIE plugs.
3 per board and one for the controller.
Currently in SA we are moving into winter.
Temps range from 17-30C ambient.
My S7 F1 is running at 66-68C most of the time with little outdoor air intake.
Set the fan to 80% (4800rpm) and the temps run up to 71C.

I am thinking about purchasing an S7 but not sure to go with 1 fan batch 16 new or look for a used model that has 2 fans?
I am also wondering if a multiple atx psu configuration is capable of powering this miner like the S5? Older models seem to call for around 1210 and the batch 16 seems to be around 1300. I was thinking of using 3 750 gold thermaltakes, 1 for each board, does that sound doable?

A few quick observations on S7-F1 / Batch 16:
- The heatsinks have changed. Specifically, the package-side sinks (the tall, lighter colored ones) have thinner fins and have a T-top central fin like the darker sinks. I believe the new design means less of the air path is obstructed and theoretically that means lower pressure drop through the box. I think this is the primary design change enabling single-fan operation.
- The hex grill on the exhaust side has obstructed columns, presumably to influence airflow patterns further back in the box. The grill is asymmetrical and has small notches along one side to indicate alignment with the hash boards.
- The silkscreened version text on the hashboards still reads "S7_SP0WER_HashBoard_45_V1.3" as it has at least since Batch 8
- The controller boards are still labelled "S5+_CtrlBoard_V1.6"
- The fan header for the 2nd fan is still present.
- The shipping weight is down to 7lb14oz or about 3.6kg; the new boxes are 35.8x21.5x25.5cm, 4.2cm shorter end to end than the two-fan boxes.
I'll get pics and look for other labeling or component changes as time allows.

how secure is it? does the panel go back on flush?
are you able to use smaller zipties and tie it right to the inner grate pieces?
Damn that is loud! 75dB.WOW! going to cry with this one.
To install another Fan you need to un-screw all 4 screw. In this case, the warranty is void. 
Look good, after install second fan. The noise is about 75 dB, temp about 63 degree. Room condition is about 28-30 degree.

can't know for sure as I am not there but it usually sits a few degrees above ambient, it's a garage with a box fan in one window sucking air out and the miners exhausting toward the fan with another window open to let air in. Nothing fancy but it ventilates fairly well. There are two other two fan S7s in there with it.
So outside is ~71F and the miner is holding with two blades at 60c and one at 56c. Clock still 700 and fan at 5400 hardware errors at .0007
What is ambient in the room its running in? how many miners are running in that area?

Well supposed to hit 76F here today and i have one of these one fan units and two of the standard two fan S7s running in my garage so we shall see how it does. It's at 700MHz currently cause it's been rather cool but I will be watching throughout the day and adjusting if needed. Will post back with what happens.
will be interesting to see how they handle as you add more and ambient heat increases. board 3 is definitely a bit hotter then the rest, seems like the fan isnt hitting that area as much
how is it running? within spec and low hw errors?

I just received few miner of the 1 Fan batch.
After testing and setup, the fan run at full speed 6000rpm. It's REALLY noisy.
I'm missing the 2 Fan batch now.

So I know how to attach a fan with no damage to the warranty sticker
http://www.mcmelectronics.com/product/83-11829?
then use 3 of the four included screws leave the warranty one alone
put a grill on the other side of the new fan with four small thin zip ties.
this fan from amazon is good
http://www.amazon.com/Sanyo-Denki-SAN-Ace-120mm/dp/B00YOC80IO/ref=sr_1_2?
do you need to do this ? I have zero clue
but I think if you do this the machine will be easy to over clock

So I will have a couple of fans from S5's that had bad boards. I think I should be able to re-use one of them as a second fan for the Batch 16 S7?
At any rate, I will probably buy a couple, so I'm grateful for this thread.
Also have a few coupons I can't use. Asking .04 BTC. PM me if interested.
Okay back to the drawing board.
Well four zip ties to the grill and the gasket may work.

Yeah simple and cheap and I think good enough to last until doomsday (aka halving).
