Technobit HEX16B - Bitfury based miner in hand

[loshia]

I am jealous because this fans are not on mine

You won't be after you catch your finger on one. One slight touch and it's slice-slice!

Picture don't show it well but it put 2 slices in the end of my little finger.

It wAs not  pleasant experience for sure. You should be more careful next time
But any way I still do want them badly

Some lawyer type is gonna pop one day, if they ship enough of these out, because the Sunon fan spec sheet says it should be used with a fan guard to avoid injury, guess who they'll blame after some kid sticks a finger in it.

But any way I still do want them badly

You're crazy to want finger munching fans that sound like leaf blowers in you home!
But I'll let you know when I get them swapped out for Arctic F9s and put them up for sale.

Ok, now i feel so stupid looking for replacement Fan.
The SUNON Maglev PF92251V1-000U-S99 is PWM fan, so what i need is to build PWM fan controller.

Did you choose this fan? I noticed the PWM blue/yellow wires were chopped off to make it non-PWM  

It would probably be best to run them at 7v by plugging the ground into the 5v (+12V-+5V=7V), then it should be 2625RPM 43.75CFM, but I'm not sure how the board or other peoples PSU will handle it. Soldering in a resistor on the 12v line, or even better a variable resister with 3 settings for 12v-overclocker,7v-normal,5v-underclocked, probably the safest option.

The Arctic F9 (AFACO-09000-GBA01) non-PWM non-temp control fan is good combination of airflow/quiet/price/safety.

Actually SUNON Maglev PF92251V1-000U-S99 is the best fan for HEX16C. You can touch the heatsink on chip area without get burn.
But since i need to take it to my bedroom then the noise will make problem.
Arctic F9 is good for replacement but i can't find it in my country so i end up buying zalman F2 LED. Zalman F2 LEd had 2800 rpm & good enough cause my bedroom had air conditioner.
Now i regret buying zalman since i can make PWM controller for SUNON Maglev PF92251V1-000U-S99.
With PWM controller i can set it at 3000 rpm at night  & 4500 rpm at daylight

Got the fans replaced with 1800RPM/43CFM Arctic F9s, wow what a difference that makes!

Unlike the Sunon 4500RPM I cannot hear them in the next room, never mind the floor above!

Saved about 3W per miner too and I don't have to worry about the kids putting fingers in them!

They don't cost much either, I got the Arctic F9's for sub £3/€4/$5, with a bulk buy deal on Amazon/eBay.

The wire is a bit thin and fiddly though compared to the Sunons.

Has anyone been able to get these to co-exist with HEX16A2's?

When i added a 16B to my 2x A2+tplink+hub the 16B starts hashing and the A2's are detected but don't hash. Power is not an issue as the 16b is from a different PSU. THe tplink is running 1.3 but changing to 1.5 did not seem to help. Any idea's?

With the latest firmware they should work.

With the latest firmware they should work.

I use 2 power supplies and have problems with the 5v power leaking from one of the Hex16Bs and competing over a shared cheap USB and TP-Link.

It was the first one I got which has 2 Power blocks on the board and 2000rpm fan, so it's easy to identify, the 5 other good Hex16B only have 1 power block and 4500rpm fans.

It would cause the miners on 1 power supply to fail soon after starting mining. They would run okay as long as I kept everything separate.

So either put them on separate TP-links and hubs or this is what I did...

Swapped my cheap £2/$3 no-name Chinese hubs (which worked even if something was leaking power) for my branded Chinese Orico hub with power protection.

I knew this Orico had problems disabling the first miner I got, but the rest seemed okay, so I taped out the 5v and ground in the USB connector for the bad one and it all worked!

Now on this hub (which has power protection) the whole rig runs more stable.
Running 25 days+ no issues 1x TP-Link + Orico 10 Port Hub + 6xHex16B + 2x350W PSUs.

The moral of this story is always use a power protected USB hub!

Either put them on seperate TP-links and hubs or what seems to be working for me right now (runs 2.5days before crashing) is I cut the 5v cables on the molex and power the TP-Link from the power socket not the USB hub.

Thanks i ordered a separate TP-Link but in the meantime some fiddling around with boot orders and it seems to be stable now.

Also replaced stock fan with arctic F9's and what a difference. Heatsink runs about the same temperature as the 16A2's where before it was cold but it was like having a jet turbine in the room!

Have some questions:
1. Is this the same on there website where they are claiming 60 gh/s with OC and shipping April 8th?
2. If it is, how did you get your hands on it early? Review unit?
3. Can I run multiple of these off of a rasp pi and USB powered hub?
4. If so, what software will I need to run it? 1000w to run 10 of them? Molex connectors to board right (one per)?

Dude, read the OP slowly so you not confused & check the post date.

This review is for HEX16B with bitfury rev1 chips.
The name of the board is the same as far the board is almost the same

Hi Martin,

what is the exact power consumetion from your HEXB V2 board?
Please add the watt of your Homepage!

Oh okay, my bad.

Alright thanks xD

[GayEddie]

Hello again all

I am running hexminerc at voltage 1100 and options 16:1500 and a hexminerb at voltage 900 and options 16:540

I was thinking of stepping them up to higher settings can someone tell me what they are and if I should or is it a bad idea?

I also have bitburner set at 1300 voltage and options 115200:32:10:50:256 can you do this board as well?

Many Thanks for any advice

[marto74]

For
hex16a2(C), 1100/1500 is the max with this HW setup, If you put 4500 rpm fan you can go up to 1150/1600
For HEX16B 900/540 is optimum , if you go up you'll loose some GHs and drain more power , so it is pointless.

Thanks for reply marto
