i dont find them very silent ... they are lower than BFL .. true... but cant sleep with them in the same room , thats for sure

Same here.  And sometimes the fans kick into higher gear which makes them even louder.
My apartment is so hot now.. I have to open the windows

That's the problem. If you want them to run quietly you need the room to be cool. The fans are temperature controlled.

I may be considering to put them outside on the patio in some kind of enclosure.

is it too hot for them to run at 61 C ?

[CroverNo01]

Hi folks

Is there a way to manually override the fan settings so they can run at a set speed rather them temp = speed.

It's just that the air temp in the room where they are stored is 3.5c max to -5c and the fan speed is 1090rpm

Would like to increase the fan speed to keep the heatsink much cooler than which it already is currently at.

As my temps are 43c on both blades yet I was getting almost same temps as in a 30c room.

Any ideas ?

Cheers

Hmm, mine run at 45 in a basement. 61 is pretty high if you ask me.

Just hook the fan straight up to the PSU instead or use a fan speed regulator in between it and the PSU.

/etc/config/cgminer state:

option target '60'
option overheat '70'

so... you are close to the fire :|

[elasticband]

61 is quite hot.

how do you have it or them set up? picture would be good

Is there a way to undervolt/underclock these devices?

If you SSH into the antminer using putty or a linux command prompt, you can edit the file asic_freq (located in /etc/config/) which controls the frequency at which the chips operate. There are several pre-populated values in the file... each option is a set of 3 entries you remove the "#" from the lines you wish to try and add "#" to the lines which will no longer be used, save the file then reboot the Antminer... I created a freq setting of 375Mhz by adding lines using the hex value "4e81" (in between 4d81(350Mhz) and 4f81(400Mhz) now my ant is running nicely at a solid 192Gh/s for a mild overclock..  There is a blurb on this in the antminer setup guide.

To answer your original question, you would underclock by selecting a chip frequency less than 350Mhz

Is there a risk of bricking the machine doing this, or will the controller still work (allowing further edits or restoring the old values) but the hasher not work?

There's always a risk of bricking a unit when you play with configuration files, but the asic_freq file does not seem critical to the unit booting. I haven't experienced an error while modifying the file, but at worst, cgminer wouldn't start based on chip errors and you'd have to go back into the file and select values which worked.

Thanks For Sushi. I did not expect gift. I am very pleased. Only have to solve the problem with the customs, which doesn't pass the cargo.
Happy New Year to all.

[gigica viteazu`]

Ocja... send them to me... no problems with customs here

congrats
