Thanks. For now I don't need to mod it, but I might a bit later. Warranty is also running out little by little so that's not of a big concern.
The hungriest fan I have around is 3A so it's OK. Another idea I've seen floating around is to use the PWM and TACHO only and power the fan from the PSU.

Any idea what is the MAX load of the fan controller on a SP20?
3A Max, the stock fan use 1.75A and we have 6A fuse Pinout: 1 - 12V 2 - GND 3 - TACHO (Fan output towards controller board for rotation indication) 4 - PWM (controller board output towards fan to set rotation speed) If you mod the stock fan, you'll loose warranty of course. Guy Are you 100% on that? The 12V and Gnd listed are reversed from a standard fan pinout. |

Can someone tell me about how many GH/s we would get from the SP20 if it was under clocked close to .51 watts per GH/s? EDIT: I found a good answer which ended up being .55 watts per GH/s for 1,350 GH/s. That's pretty damn good!!! Is it really 60+ db?
not under clocked see my settings aboveafter much testing and firmware down to fan speed of 20 the machine is 67 db. with super underclock to 1025 gh and 477 watts. fan can be set to 10 or 15 vis ssh. It is still not a quiet miner. I spend 746 watts and I am getting 1350 gh or 0.55 watts per gh this allows the lowest fan setting 40.. give me an hour to find my db meter. right now I love this piece of gear……….. 746 watts for 1350gh out fucking standing. this is current power use I use an evga 1300g2 unit  current settings and hash rate  |

Im hoping to get an SP30 in the next few days, but am worried about the noise. I had an SP10 and had to run it at 1.1TH to achieve an 'acceptable' volume, which was still in large excess of my preferences.
I want to limit the noise of the Sp30 to about the same volume as the SP20 at 20-30%. I assume this will mean running the PSUs at <75% load, probably aiming for 3.5-4.0TH. Anyone have experience or suggestions with this? @Zvisha?
also, does the auto-fan work well with the new scheduling feature? Is it possible to set different fan speeds for the different modes? (ie: two versions of the /etc/mg_custom_mode settings that I can adjust via SSH (to put fans <20%))

It's not a standard fan connector. |

Guy Are you 100% on that? The 12V and Gnd listed are reversed from a standard fan pinout. Regarding the pinout, yes. The SP20 fan datasheet is available hereRegarding current rating - we checked again regarding the connector UL specification. In order to meet them, the maximal current allowed is 2.5A (not 3A as I wrote earlier). Also, 24AWG wire is required to meet this current rating. Guy |

speaking of that fan connector. any one been able to source it. I was thinking of a few mods to do on one of my sp20's

Just loaded up 2.6.10 to try out the scheduling, and have a few questions about how the 'regular' settings factor in:
1) If i want to range from 0.62-0.70V I assume I either need to fix the fan speed based on quietly cooling the max speed (say 20-30%) or use AUTO. I really want to run the fan at 3-6% during daytime hours though, does auto bring it down that low?
2) what about the max wattage? I imagine the max wattage has to be set high enough that it is sufficient for the higher power voltages
EXAMPLE: I want an SP20 to perform at 1100/550w from 7-11am and 5-7pm, 1300/700w from 11am-5pm, and 1500/950W from 7pm-7am. The entire time i want it to keep pretty quiet, no more than 8% fans in the daytime and <40% is acceptable for nighttime
-what is my starting voltage (if i do 0.625 will the power-mode take forever to reach 0.71V? if i set 0.7V, will the opposite happen trying to reach 0.63V?)
-what is my set voltage for each time frame (I have a rough idea, but not exact numbers - I'm guessing 0.63, 0.65, and 0.71 respectively)?
- whats my max wattage (190W to limit the unit to the desired ~950W total)
nighttime power is about 35% cheaper so i want to make use of it without having my daytime fans obnoxiously loud

Agreed; 2.6.10 is pretty cool, but please add a fan option to the schedule |

I just got in a couple more SP20s. My existing are at firmware 2.6.9 however the latest firmware the new ones fine is 2.6.1. Do I have to do something special to get the 2.6.9 or the 2.6.10 mentioned? I really like the auto fan capability of the new firmware.

Just log into the miner interface, click Firmware Upgrade, click manual. choose the 2.6.10 - Test Version and upgrade. |

now if only there was a way to code the SP20 (or whatever) to automatically adjust its hashrate (watt usage) based on current value of bitcoin and/or the current network diff.

Just bought another 3 pack as I'm really enjoying my SP20s.
Great work on the new firmware, very happy with the new features and proper xnsub implementation.
If I want to run them on a gold+ power supply at 1450+gh, what do you recommend ?
If using nicehash as primary pool, is it better to use f2pool versus btcguild as f2pool is PPS?
Is there a benefit to the 3X gen over the current 3 pack deal with SP20Es?
The way I calculated things, made more sense to buy a 3 pack.

The shipped weight of a SP30 is 16kg, dimensions of the shipping box are 750 x 600 x 160mm. External dimensions of the case
are 555 x 440 x 90mm. |
