So I have a dead hashboard. I did the logical thing. I dismantled the E9+ and switched boards, switched power connectors and data cables to the board.

Still the same, the conclusion is a dead board.

I took out the dead one, and moved the remaining 2 boards into this position - board 1 -->empty space --> board 2.

And I remove the intake fan and just run the miner with the output fan. To my pleasure, its is now running at 6plus TH/s and alot quieter. Temp of the two working boards is constantly at about 65 degrees C.

Now I'm thinking to get 2 lower RPM fans for both push and pull, and replace the current miner's fan. Probably like 1000-3000 RPM, maybe?

Any recommendation pls? Need the model number preferably.

I would not recommend it,
but if you really want to try to go that road,
I would recommend getting two of these: Enermax D.F. Storm (max. 3500rpm - 155CFM)

Hi Matti, wow you are fast.

Yes I'm sure I am going down that road.  Cheesy

Thanks for the recommendation. Great idea, I was thinking along the same line too (about getting server fans).

One last question - what is the most ideal specs for these fans to be quiet like less than 30Db? For eg. DC12V and 1.6A? about 3000+ RPM?

So your fan specs should be about in this level area:   enermax d.f. storm <--------       --------> delta electronics qfr1212ghe

Yep.

As a common notice I just say that those Enermax fans are not providing enough cooling in most situations.

Yes, I undertake the risk and am prepared that the miner will be bricked due to over-heating.

It is a piece of door-stopper / paper-weight, as most of us affectionately refer to, anyway.

If I can savage it and put it to use, I might even make a video and post it here for a giggle.

I received a good question via PM about a replacement cooling fan,
and I thought I share that information also in this thread.

Quote
Where do you find the Deltas with the little connector for the E9+s?  
Had one come with a dead fan and Ebit has been a shit show for warranty work.

Thanks!

You can order a Delta QFR1212GHE cooling fan for the Ebit E9+ miner as well.

The connector is indeed little tricky, since it is a four pin JST XH 2.5mm connector.

I have not found any fans in the market equipped with that particular connector.

I think the most easy way would be cutting the old broken fan cable and the new fan cable,
and then connect them together in a reliable way (soldering or wire crimp connectors).
Be sure to know what you are doing or ask a friend with skill to do it!

So you need to modify the fan cable yourself to have a JST XH connector installed in the new replacement fan.

Here is also a list of replacement cooling fans compatible with the Ebit E9+ miner:
  • Cooler Master A12038-60BB-4RP-F1   <--- this is the original stock cooling fan
  • Delta Electronics QFR1212GHE
  • Delta Electronics QFR1212GHEXUM
  • Nidec V12E12BS1B5-07
  • Sanyo Denki 9GV1212P1J01
  • Shengjiu SG121238BS
  • Sunon PSD1212PMBXA-F-PWM

Ebit products absolutely SUCK.  Damn thing died first week.. had to spend $200 to send the controller board back and have them send it back to me without any result.  Never connected to the internet.  Support sucks, product sucks, communication sucks.. and they have no common sense to hire someone to translate their own documentation for install into languages of countries they sell the product.  Complete waste of over a grand.

Hi,

I'm rather new to this.

Earlier I had my miner at a "company" who did everything for me, but after a bad year they decided to return the miner to me.

Here at my place the miner seems to get too hot, and it shuts down after a few minutes. The PLL is set to 750 - is it possible to reduce this to get a lower temperature?

I never tried this, so unfortunately I don't know for sure.
The graphic user interface doesn't support it.

Have you tried asking Ebang about this via skype ?

Okay, my bad then..

Why don't you simply set it to a lower PLL setting?

The reason I asked my first question was because I was afraid I would destroy my miner by changing the PLL.

I redused the PLL and the miner got a lot cooler, and I was able to do some more digging before it shutted down.

In the interface I noticed one of the fans had a really low RPM, and after dissasembling it, I noticed the fan did not work at all.
The fan on the PSU doesnt work either  Undecided

The provider of this miner told me it had been running for 2 months, but I have a feeling it has been used for a long time. Is there any way I can check for how many hours the miner has been running in total?

@McMCrypto
I have no idea.
The Ebit firmware always was a 'clumsy' one.

Unfortunately I don't have a E9+ anymore to test things..
