Re: Antminer D3 Blissz firmware (25/11 update available!)
25/11 v2 recommended UPDATE
I really recommend to update to this version as it brings more stability / + small hashrate improvement
Download:
https://mega.nz/#!DowkVLgD!qVz5xnC2tGpUKKcjd6_kdkVjIwSG7-EBUkq1e_rX5Mg
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)
- increased upper limit frequency for overclocking. (not recommended though
)
- dev fee kicks in a bit later now after changing settings
know issues:
- switching pools can sometimes cause the miner to wait for work for 10 seconds.
happy mining!

Sent you the link of the fluid to your inbox.
From what i know, you need a big tank that fits all of the boards from your miner, a top tank that install the Cooling Coil to do two-phase operation, and of course the 1 gallon fluid that cost $300.
Off topic, but only slightly considering Blissz originally set out to make a silent machine...
That is the fancy 3M Engineered Fluids method... the hippy non-toxic way is to just use mineral-oil or some other suitable dielectic blend. About 90$ for 5gallons. Less in quantity.
Note, there are some serious hippies out there too! Not just over-clocking gamers up for a laugh.

Note one of GRCs products is a "hash-tank" comprised of S9s up to 5800Th/s squeezed into a 40' shipping container.

The tricky bits are circulation and heat exchanging... but not problems that haven't been solved a million different ways before. I'm leaning towards trying a recirculating pump and a automotive transmission oil cooler+fan outside for my baby farm (two D3s)! If I lived in a colder climate I would consider a classic household radiator and dump the heat inside seasonally. If that can't move enough heat I'll have to try to build a evaporative cooler and heat exchange with water.
