S9SE/S9K Fan control

[xkelvinchiax]

is that any solution for change the fan speed ?

the fan is too loud for me, i want for LPM

[Pendrak]

-Active exaust the room (with fans) to make the fans slow down.
-Clean then if they have dust.
-Change the fans, the ones that come with the miners (Nidec UltraFlo) are too loud compare with a delta or other brand and they are 1.65 amp fans (you need 2.6 amp fans, they move more air).

how do you get lpm mod on the s9k?

as far as I know the s9k only has 1 speed.



I could teach you how to make really quiet

s9
s9i
s9j

I made lots of 2 board units designed to down clock and be very quiet

Those are great advice, however, none of them actually answers his question, regardless of using a different quieter fan, he would still want to set a fixed a static speed on them, OP a simple search would have answered your question, I wrote a complete yet simple guide on how to achieve fixed fan speed on almost all Antminer models.

how do you get lpm mod on the s9k?

as far as I know the s9k only has 1 speed.

Using the same tricks to show the fan settings, you get to see the LPM option on S9k and S9e, I have not tested it, but it does show, please follow the same guide to show the hidden features.

cool I will try it.

I don't think the new firmware allows it.

The sept firmware lets you do it.

the nov does not.

and after some trial and error both nov and sept firmware are doing lpm.

man the nov firmware is really bizarre.

it reads -4121 gh hashrate

the pool reads 908 gh

the kernel log is weird

it claims. the mining failed at 23:55

So over night I ran the modded s9k. ..... via inspect page options

and I don't know what the f is happening .  I am using team viewer so I can not measure the power drop.

yeah hash dropped from 13 to 2 but. it is easy to see really low fans and really low temps



here is one not touched higher hash rate but way higher fans and temp.

I wonder just how much I lowered power.

A lot for sure but I need to drive up to Clifton to measure the power drop. if power has dropped to 200 watts vs 1300 these are very nice solo mining gear.

[mikeywith]

man the nov firmware is really bizarre.

It is, everything about the S9k is bizarre.

it reads -4121 gh hashrate

Maybe it's mining the current block -1  

yeah hash dropped from 13 to 2 but. it is easy to see really low fans and really low temps

This is way cooler than immersion cooling, never seen a miner that run at temps this low, if you set 100% fans it will surely drop below 30c for chip temp, but I am not sure that will be good for the miner, anyway, 200w for 2th wouldn't be so great, 200/2.2= 90w/th, it would be cool if it was 150w or 70w per th, I doubt that anyways, but please post the results when you get them.

I played around and was able to get one miner to go back to default settings.

The other one I switched to solo ck pool. it does mine there.

https://solo.ckpool.org:444/users/146UJM5kgzLVUV23CXCf33KQKHckoX1gx3

Code:

{
   "workername": "146UJM5kgzLVUV23CXCf33KQKHckoX1gx3.191",
   "hashrate1m": "2.15T",
   "hashrate5m": "1.99T",
   "hashrate1hr": "1.97T",
   "hashrate1d": "396G",
   "hashrate7d": "62G",
   "lastshare": 1591462901,
   "shares": 8882258,

   "bestever": 7313769

What are the default settings? your gear on cksolo pool shows

"hashrate1m": "5.05T",
 "hashrate5m": "4.72T",
 "hashrate1hr": "4.68T",
 "hashrate1d": "3.74T",
 "hashrate7d": "1.74T",

Looks like 4-5th is the actual hashrate showing on your miner's status page, which is still strange, S9k running on E-LPM should mine at 8-9th not 4-5th, or at least this is what the other S9 models do when you use Enhanced LPM, when you activate only LPM it means enabling asicboost which doesn't affect the hashrate but gives you about 200-250w drop in power consumption, but the K version seem to have pretty different settings.

[xkelvinchiax]

is there any solution for speed up the bootup time of S9K and S9SE?
