Sorry to bother you again with this non-so-relevant issue, I just found that I bought the non-PWM version of these fans, while the ones in your link have PWM.
Do you think that it will affect the noise? As far as you know, is there any kind of PWM support in the board, or they will just work the same? Or the support is not even needed?

Then your hardware is broken i guess. It does not have to be the blades, could also be the Raspberry Pi (mini computer) or the controller board that is broken. Heck, it could even be a broken PSU. I have also seen broken connectors that needed to be resoldered. I guess it would be best if you open up a new thread where we can discuss your hardware issues.

The instructions are in the first two posts of this thread. If you are by any means not sure what you do, please try the original firmware images for Dragon Miner 1T, 1.5T and 2T (currently uploading) linked at the top of the thread.

I am sure we can help you with more specific questions when they pop up, maybe for the windows stuff anybody else can jump in. I heard good things abut  winscp https://winscp.net/eng/download.php

no hardware should be broken, as it worked when i got it, i just fucked up the sd card and lost the original image.. since then i havnt been able to find a image that worked...

next thing is, im no pro at putty/cgminer thing. so i got no clue on how to deactivate volt settings unless you can link a guide? i know how to enter putty and follow a guide. but thats it  Undecided

Can you please deactivate the voltage settings? It should definitely work as long as the Hardware is not broken.

Thank you, can't wait!

Can I ask you why the Pi needs overclocking?
It's not what i would call overclocking. Modest mode is really safe, but can also be disabled if you want. It's giving cgminer more CPU power. More relevant ist the memory that i adjusted for server runtime. It is
split.gpu_mem=16

Ok, I don't think I fully understand what you mean, I'll do some researches when I get home!
And will, of course, install the firmware!

The stock fans are horrible! I replaced the fans with 4 spare arctic fans i had spare.

Hope that helps! Got it down to 35dB.

Ps.: A new 8GB Image is ready, but i am on the road and will upload tonight.
Thanks, I just bought four. How noisy is yours? Compared to a desktop computer?

I'll be back home in two days, can't wait to try the new firmware!

Fixed IP and DHCP-enabled images are currently uploading.
Should be done in about 2 hours. All instructions are now current, also.
If you are unsure - AMA!  Cool

I have 2THs version, so I used 8 pcs Sunon HAC0251S4-000U-A99 which are good quality, very quiet and very cheap (about USD4/pc), noise is less than 30dB and my temperatures are less than 50C. It is very similar noise to desktop computer.

Cheap and easy way is to use USD1/pc DC-DC buck converter from ebay which can lower voltage of original fans, but they are still a bit noisy even at lowest speed.

yeah the file unpacked is way too big, using win32dskmgr, but obviously it would not fit onto the poor little 8gb card.

i hope there's aversion that can be easily flashed.

thx.

Hello,
I received mine some days ago, the problem is that it's really noisy!
My idea was to keep it in my apartment, because I thought it would make the same noise as an old desktop computer, but it's way louder!
Do you have any hint about making it less noisy? Some replacement fants or something else?
Thanks
