Asked this earlier but didn't see an answer;
Is there a way to change the mining speed/overclocking/fan speed via a cronjob like I do with my SP20 boxes?
Short answer - no. Is there a long answer? :p

Short answer - no. Is there a long answer? :p There just no crontab at all in firmware, and no space for additional software, i don't understand why they used 256 mb flash , and left for /config only 20 mb, so we are limited to 20 mb firmware size. And you simply can't control fan speed, also there is no possibility to change voltage, you must raise/lower input voltage to overclock/downclock. I'm kinda expert in s5 ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) Maybe i can rebuild u-boot and change partition layout, but i need beaglebone black for experiments, and don't have money to buy them ![Sad](https://bitcointalk.org/Smileys/default/sad.gif)

It appears Bitmain is shipping some used hardware as part of the Batch 5 units. I just received 2 S5's and one of them has bent cooling fins on the bottom, and a considerable amount of dirt in the fan and cooling fins along with scratches on the sides of it.
I'm new to AntMiners, but my experience is not starting off as a good one with Bitmain if they ship obviously used hardware, while claiming it is new.

question about these, i dont like how the top is all open, they will get very dusty after awhile.
if i cut some cardboard to fit the opening and tape it down.. making holes in it where the plugs go.. would that void the warranty at all? would it cause any effects? the fan seems to blow enough air, so i dont think that will make them get hot?
it might even quiet it down some..

I doubt it will have any appreciable impact on the heat of the box.

I did something like this with mine. I used a thin piece of plastic and trimmed up a top and side plates and taped it all together. I also set up my scythe grand flex pwm fans as push pull. I am running 64/65 temps and it seems just as quiet as my s3's. I will be testing other fan combinations over the next few days to see if I can get it under 60 and keep it quiet without underclocking. If anyone is interested I can post pics and results with what I find out.

Please DO NOT place cardboard or any flammable item on top of the Antminer. It can be a fire hazard.

What about some thin plastic like the sides. Does it get hotter on top then the sides?

Hello all,
sorry but no time to read all the previous treads...
Do anyone actually purchased the miner, got already and started to use??
Thank you

What about some thin plastic like the sides. Does it get hotter on top then the sides? [Unofficial mod] If you choose a plastic type with a Tm of 100C+ you'll be good. Alternatively you could use electrical or duct tape.

Got a new S5 a couple of days ago. It runs VERY hot compared to my older ones. Like 20C hotter . Anyone else see the same thing?

Just the opposite for me. And hardly any errors. 3 HW errors in 27 hours of mining at 400 MHZ.

ThunderMine, Yep, this is obvious if you not first time buyer, this is from their cloud, i'm glad if i receive miner in working condition ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Did I miss something on their website for the product? It references a "final production run", not used cast offs from their own mining farm. One unit I received looks pretty good overall, the other looks like it's been running somewhere sitting on a dirt floor for several months. Neither appear to achieve a stable hash rate near the claimed spec. I'm lucky to get over 1TH out of either one although the GUI claims all the chips are fine. Only running around 48 C on temps (seen 51 a few times briefly) in an ambient temperature of around 72 degrees F (that's fairly normal room temp for the metric minded), but with the suboptimal output, not surprising I guess. Fans at 3360 RPM at 48C on the dirty one. Seems like the fans could back down a bit. Other is slightly less and runs slightly hotter. I got the impression from the reviews that they built a pretty good miner, but I'm getting a little different impression first hand with these two. I'd be willing to bet the fan on the dirty one fails pretty soon. The dirty fan is definitely louder than the other. I can hear it over my ASICMiner Prisma even, and that thing is loud. At least it achieves (exceeds most the time) its claimed spec for the noise it makes though. I'm way outside the -5% on both these units. Average hash after an hour, 998.88GH/s on the dirty one which seems to run slightly better than the other speed wise. I've tried different pools including AntPool with the same results. Has 1947 HW errors in an hour too. How do I tell whether I have the latest firmware?

I would have said my first one I took out of the box was new, but the second is definitely used. Neither run right though. My HW error rate exceeds my Accepted rate. Reset one a few minutes ago. 340 HW errors with only 302 Accepted after 10m46s running. Added: This is with one board reporting 48C and the other 49C at the default 350 frequency. Says all ASICs are fine.

How do I tell whether I have the latest firmware? definitely something weird going on.. my was new, shiny, and unused.. unless they did a really good job of cleaning mine. I went back and looked all all 4 of my new ones really closely, the ONLY wear and tear I could see is possibly during the QA burn in period, there's very light dust on the edge of the fan, like you'd expect after being run for a day or two at most. The PCBs are all 100% clean, no hidden dust in any of the nooks and crannies, no dust inside any of the heatsinks. I don't believe any of my 4 were used. I have two more arriving monday, I'll check them closely as well.
