I could use a 5 blade English version. Is it there instructions on how to do this correctly, and with an autostart feature (the 5 blade model I got a month ago doesn't auto restart hashing).


Anyone has this 5 blade version for the old 5blade dragon ?
The 5 blade dragon works @200hash for every blade (not 250)
If I run the miner with new dragon firmware every blade works@250 but i  get 30% hardware errors

I replaced the Nidec TA450DC B35502-35 235 cfm fan and the other mystery fan with 2 of these Sanyo Denki 109R1212H1011 fans pushing around 102 cfm each and under 43dbs the units purr like kittens and still keeping the temp under 68c, average is 55-57c. Got them off Ebay from dealer in Cali. there is a 150 cfm model but then you back at the 56db noise.

Is that good or bad to purr like a kitten?

Does anyone know how to ssh into the miner to allow read / write access (api-allow) so I can manage switching pools on the fly via cgremote? It just shows up as read only right now.

thanks!

Thanks for the info on the fans in the Dragon.  I think there is a bit of confusion because it seems to me after taking them out that one fan is heavier (and more powerful) than the other. 

Seems like the big fan in in the middle of the machine (prob 200+cfm) and the other is more a regular high speed (130+cfm).  I think this is because one fan hits more blades than the other.  I have not replaced any of them yet, but may in the future if I can find some nice high speed fans that aren't very loud, and hopefully can cool even better than the ones it came with stock. 

The price on these are very good, so I am sure they had to save money on some parts sacrificing cost for decibel level.

Can somebody please send me an image of the SD card?  Cry my SD card became corrupted and I can't find any images anywhere.
From what I can tell you just need to read a good SD card with this program: http://sourceforge.net/projects/win32diskimager/ to create a backup image to restore from, if someone could do that with a working SD card and send it to me (with MEGA or something) I'd *HUGELY* appreciate it.  

https://dl.dropboxusercontent.com/u/92967009/dragon_image.7z  
thank you for providing this img file, can you specify what is the version of this img file, four blade version or five blade version, english version or chinese version?
and also what is the initial ip address in this img file

Chinese, 4 blade, you will have to check the from panel for IP, I thing it was 192.168.1.163 but am not sure.

If anyone has an english image -- please post


I have the English for 4 blades.

If anyone interests let me know so I will make the dragon surgery.
please upload it into dropbox and paste the link, i will paste your link in my trouble shoot topic

A link https://www.dropbox.com/s/yz02suc4j24ium4/dragonboot-4BLADE-ENG.7z to the 4 blade english ISO.  When unzipped willl be a little under 8 gig.  It's ip is http://192.168.1.134/

And as a extra precision use a 2nd card just to make sure it works with your machine as well. This is the software used to make image http://sourceforge.net/projects/win32diskimager/ .  It also can write images aswell.

I have English for 4 blades.  It is a 8 gig image.  So you will need a 8 gig card.  Definitely would need zipped.  Are the people needing English 4 blades or 5?

I already have my own hardware, and the noise isn't that bad.  I was just curious if I could put in a high powered fan that isn't quite as loud and would do the same job.  I have searched everywhere even looked up the brand of the fan inside the machine but can't find the stats on how much airflow it puts out.  I grabbed a few 130cfm and that is pretty powerful... the most powerful I have seen anywhere online is 200cfm.  So I am guessing you don't know what airflow these have stock?

They are around 120-125+ stock fans.  Which is pretty decent airflow, but not the quietest.

yopix is correct.  220-230+

Delta TFC1212DE has 250+ CFM although they are kinda expensive.
