Do you have a L3+ of if I snapped some pictures of it's board could we do the same with the L3+ and get better efficiency.
I don't have an L3+ but if you can make a good closeup photo of the electronics near the 4 mosfets, I can take a look for you

That is some nice tweaking. Txs for sharing 
Impressive, well done. Undervolting would void the warranty prob like with oc.
Yes I will add this to the topic as this definitely voids the warranty on the mining boards
On the other hand, this will improve efficiency and heat problems, so on average this will improve the lifetime of the miner
The antminer D3
As an owner of the October batch of the antminer D3 I have good news. I now run my antminer D3 stable @ 15Gh/s with just 750 watts.
I decided to go for a mod, because I couldn't run the fans at full speed because of the noise. Therefore I could only run 13 Mh/s @ 850 watts before the mod, which is now not very profitable.
The mod:
To get there I tried to reverse engineer the power circuit of the antminer D3 mining boards. Unfortunately there is some chip which I still don't know the specs from (labeled ADP BDY+), but I found out it's controlling the PWM of the mosfets.
So I tried changing the resistors around it and found out that changing the resistor R80 controls the voltage. Woop Woop
So if you want to do the mod I advice to replace R80 by a 25k ohm potentiometer. The voltage can be measured over C948
Improvement:
without the mod the total voltage supplied to the asic chips is fixed @ 8.15v on the October batch. That means 1300 watts for 19Gh/s
After the mod the voltage is fully adjustable by using the potentiometer. It also allows to increase the voltage for overclocking if you want to do so.
But overclocking is not my goal, I wanted a silent miner: Therefore I now run my boards @ 7.1v @ 430 Mhz stable. That means 750 Watts for 15Gh/s
That is 50 instead of 68 watt per Gh/s

The mod is quite easy if you have some proper soldering skills, but it's tricky if you don't have the proper tools / not have a steady hand...

ps. I will make new higher res zoomed pics soon.
Other possible mods:
Fan mod: (only when undervolting)
as I don't like that noise at all I also did some fan mods. I added a voltage regulator on one of the fans to decrease the noise during startup. cgminer won't allow you to go bellow 5000rpm othwerwise the miner fails to start.
Furthermore I replaced the second fan with a 2000rpm silent fan. To make this work you have to use the yellow wire (fan rpm) from the first fan as wire for the 2nd fan. Otherwise it detects a too low fan speed on the second fan.
I can say that running both fans @ 2000 rpm is acceptable to run it in a living room now.
Power supply mod: (only when undervolting)
By default the power supply runs @ 12.2v. I used the potentiometer inside to make it run @ 12.05v. This saves a few watts of power as well. Furthermore I added a regulator on the fan, to run it at 5v as this small fans makes an annoying high frequency noise when running at full speed.
Support
I hope this information does inspire you and help you improve the efficiency on the antminer D3. I hope to improve the mod: as I want to look into a software mod to enable changing the voltage from software. This would really open up the possibilities for all the users.
To get there I still look for a copy of the November miner firmware as bitmain is not supplying this yet. If one can login using ssh and make a full copy of the all the files that would be really welcome.
Support on this mod project is more than welcome as I want to have a spare D3 for modding the software. A (damaged) donor D3 or S9 would be very welcome as well, as this baby really needs some mods too

hard mod information (depricated)
UPDATE 16/11/2017: I successfully modded the firmware which will add unlocked voltage and fan control, so I advice NOT to hardware mod and see how far you can go with the firmware mod. If you want to undervolt more I advice the hard mod.

- improved pool switching behavior
- improved startup stability of all chains
- cgminer binary optimizations
Please update versions older then 26/11 as it can damage your D3.
Changes 26/11:
- Solved an issue where loosing your network connection for a longer period could burn out your hashing boards as the fans run at a very low RPM.
Changes 25/11 v2:
- Hashrate calculation is now according bitmain stock firmware (displayed hashrate is ~3% higher now)
- + ~1% performance improvment by providing the work faster to the ASICs
- removed dev pool from miner status page to speed up webinterface and avoid confusion (exact dev mining details are visible in the kernel log)
Changes 25/11:
- fixed auto reboot on low hashrate / xxxx
- fixed issue where temperature readings could be wrong
- fixed fan error on some units
- improved stability
- allows for zero RPM fan (all custom fans should work now)

Changes 23/11:
- way faster mining startup after changing settings / reboot
- adds the reboot on low hashrate option
- ~ 1% improvement on effective average hashrate *jeeej*
- fixed flash upgrade speed to new versions
- added AUTO FAN profiles:
The AUTO default profile is the one that's in since the start, the performance is more like the stock bitmain auto fan profile and the silent profile keeps things nice and quiet. Manual mode is for setting a static fan speed.
Changes 21/11:
- Firmware now based on latest Bitmain firmware (20/11/2017)
- made default bitmain voltage a bit more clear in the list.
- Applied a more silent AUTO fan profile.
- Fixed the high fan RPM at startup when using AUTO fan speed
- several webinterface fixes

- new graphics. (You might need to clear your browser cache)
- Switching pools overhead lowered (now mines for fee every 2 hours)
Changes 18/11:
- fixes the pool priority, it will now mine on your own backup pools when your first pool goes down.
- Dev fee lowered to 1,5% (it was actually 1,66%)
Changes 17/11:
- fixes the high fan speed when switching to the dev pool and back to your main pool
- fixes the close PIC and need reboot!!! error on the original bitmain firmware
- Made the ASIC default voltage less confusing as it is now comparable to the default bitmain voltage.
- Lowered the AUTO profile fan RPM's a little bit.
know issues:
- switching pools can sometimes cause the miner to wait for work for ~5 seconds. (improved from ~10 seconds)
- loosing network connection doesn't stop the mining boards properly (this is default bitmain behavior, but I don't like it, so it will be changed in the future)
Important:
- As this firmware allows extreme overclocking / reduce fan speeds, I am not responsible for any damage to your miner. So flash at your own risk and please use the firmware wisely.
- There is a 1,5% mining fee as compensation for the effort I put into this project.

for silence and best efficiency / miner lifetime (my personal preference)
Expected hashrate: 15Mh/s to 17 Mh/s
Expected power usage: 700 - 780 watt
set the frequency at "400mhz", set the voltage to "lowest". Now slowly increase the frequency until you see HW errors. When you have a few HW errors an hour you found the sweet spot
set the fan speed manual somewhere between 20 - 30 percent. Chip temp should be somewhere between 75 - 80 degrees max.
For stock performance at lowest possible power usage
Expected hashrate: 18-5Mh/s to 19Mh/s
Expected power usage: 950 - 1100 watt
set the fan speed to automatic mode.
set the frequency at "525mhz", set the voltage to "13". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot
For Extreme performance (this is not recommended for 24/7 usage)
Expected hashrate: 21Mh/s
Expected power usage: 1300 - 1400 watt
set the fan speed to automatic mode.
set the frequency at "600mhz", set the voltage to "18". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot
Back to bitmain stock firmware:
In case you want to go back to the original firmware:
- set the voltage of all boards to 13 before flashing back (just to make sure...)
- download and flash this image: https://shop.bitmain.com/support.htm?pid=00720170915192851224mJ36J1ap066E
- reset to defaults
Firmware recovery:
This is only needed if the miner doesn't boot anymore (In case you had a bad / interrupted) flash:
- get a microsd card
- write this image to it with win32diskimager: https://shop.bitmain.com/support.htm?pid=007201604120945219855QObfk20066C
- insert the micro sd card in the d3 controller board and power it on. The miner webinterface will come up again. (maybe under another ip)
- redownload the firmware and flash again.
- remove the micro sd card
