If you use your miner to maximal settings in hot envoronment don't use the auto - auto is only good when you are under-clocking.[/color]

Thanks, that part works well, I have one under-clocked a few feet from my desk and Auto has taken the fan down to 19%.

Top tip Zvi, thanks .. I never knew that.

Added auto-fan option in 2.6.6.
You can select "Auto" from the fan menu in settings.
It's experimental, please give your feedback.

First 5 minutes the fan speed set to 60% and can not go down, then it starts going up and down based on temperature.
The algorithm goes up very fast (10% every 10 seconds) if some ASICs above 120c, and down very slow (1% every 10 seconds) if all ASICs under 115c.

If it misbehaves for you let me know.

would be nice to change the start point of the option. for underclockers, starting at 60% and waiting almost 10 minutes for it to creep down to 10-15% might be excessive, and a 20% or 40% start option would be good
I prefer to keep it high, since if the ASICs will hit 125 before the fan increases it will start downscaling voltage, and go into misbehaving. But then, since this feature should be used when under-clocking only, I guess I can move it to 50%

I'm glad you guys like my idea about scheduling

@zvisha: would temperature/frequency changes from scheduling have and significant negative effects on the hardware? Ive always stuck to the concept of 'if its working, dont change it' because some computer hardware does not handle significant and repeated temperature/vltage changes very well.

I don't expect it will, since the HW changes rate all the time. I will see how hard it is and we might do this one. Most complication is in the UI, to enable cron to change /etc/mg_custom_rate and restart minergate.

Also appears that it won't take the fan any higher than 80% on Auto. I have one I was running at 90% fan and set it to auto and loop 4 is yellow 120 and the fan has been at 80% for a while now.

That is true.

could it be possible to gather the firmware suggestions in a list and edit that list and extend?

~~- true fan speed control by target temp~~
- scheduling certains mining speeds(voltages)
- individual voltage limits as right now for the back chips
- Timezone "bug"? first page graphs are always UTC?
- enable API in own subnet/net by web interface
- include fan speed in API datasets
- change host name in web interface
- other pool options than failover only
- sum of PSU(unknown) input watts in addition to DC2DC watts, either on ASIC Stats page or main page, as for estimate of power at wall or PSU efficiency
- Graphs on the first webguy page, there should be a button to disable some/all of them.
~~- Poll page could be managed on the front page with up&down buttons on each pool~~
- GUI switches to turn off SSH would also be a good thing, plus for advanced users some sort of iptables in the OS for security.
~~- show ASIC Stats~~

The three sp20 batch is the best deal, if you purchase your PSU's wisely.

The SP31 is loud, but really not that bad- three sp20's would be louder

The sp31 is nice and neat, no random cables from power supplies.

Thanks, that's what I was seeing also. I've got a nice little 220v 30a circuit just sitting downstairs, but I think I'll save it for the next batch of 'home' miners. I've already got 6 of the sp20 and 2 s5 units running at the office because of the noise.

This has probably been address already, but what is the sound difference on the SP20 vs SP31 or SP35? Also, unless I miss something, for the $/gh, aren't the SP20 a better deal than the other two options?

Well I put a miner ~~with~~ where my mouth is so I can do a comparison. I do see the fan speed on the Asic status page but not the main page. At least that would be a simple fix in the code. Let it run of a day and will let you know how it goes. Thanks.

Edit: I assume 10 is the lowest speed at the auto mode will go as well.

Also, fan speed displays 0 on main page. would be nice to know what the setting it settled in on is.

thumbs up for implementing the first point of the user wish list so fast.

now I can data log the db vs. fan speed more easily....

computer's CPU and GPU work based on frequency/temp changes all the time and last quite a lot of time. i don't know how you got hte idea of computer hardware not liking it.

To clarify running at loss means no more net income. So capital expenditure is nothing to return back anymore. Less than gross roi

ouch, 0.5w/GH isnt profitable? I'm operating 1w/GH gear still - at a marginal (~$0.75/day) loss though, but am bullish we will see >$250 sooner than the time and annoyance of putting money into an exchange

1 TH/s makes $2.44 daily income
2.44 / .5 / 24 = $.20/kwh beak even point.

Anything over $.20 per kilowatt is running at a loss.

Did anybody tried to run SP30 more energy efficiently? If yes, care to share the settings and what the energy consumption/hashing speed will result?
I have my units in hosting, so cannot play with settings as easily as with SP20 at home.

A few that I tried, the green was the optimal until the recent price drop, now they are all offline, UK electric rates kill any chance of profit Sad
