Adding fans won't do too much unless you're maxing out the stock fan... all it will do is make the stock fan slow down due to pwm. If you add fans, it cools the boards and the temps drop and the stock fan will slow down until the temps rise to 40^o again.

If your fan speed has increased since adding the second fan then it sounds like it's causing more blockage than increased air flow.

If the chips reach 50^o and the stock fan is running at over 3000rpm then it would be time to add fans to keep it down to 40⁰ again.

I've added fans to my overclocked unit, but that's only to keep it quiet and I've added them on the outside blowing straight on the last 3/4 of the chips, it seems to produce better results  

EDIT: P.S. if you want to drop the temps, then just remove the blue wire from the fan connection as mentioned further above and watch the temps drop to 30^o as the fans spins up to crazy speeds 

How cool? I have also install 2nd fan. I have found one same as orginial...

After installing, hot air is pulled by 2nd fan, but from management page, show same temperature >:(and the rpm of the 1st fan become higher..., form 1900 to 2200?

I'll go out on a limb here and say: It runs cooler.

My immediate impression is that your 12V DC power is far too low. Equipment will not handle well outside of a 11.7-12.4V range and it is almost certainly your PSU being a bit too weak for the job, or running long 18AWG cables that are losing voltage across the distance (partially as the cables getting warm).

I *imagine* that the all 3 capacitors should act the same way when tested - its possible that one might be poor quality and shorting/draining when tested with the meter.

2ND THOUGHT: I am not sure how the power is given from the 12V in to the 4 'segments', but if it is a chain across the the 3 capacitors in a rightward direction the capacitor could be broken and the multimeter is causing the connection to complete, but designed not to carry the required amperage through its probes -> hence voltage drops without a valid circuit. I am not an electrical engineer though, so a 2nd opinion would be a good idea before you take the soldering iron to it. If it is the capacitor, it would be a very easy fix if your friend has the tools for fire-point soldering and some experience with phones. (I personally have only a larger iron so I would not attempt a smaller component like that without buying a new tool or two)

By the way, which section is the one showing all x's? The second one I imagine?

I made direct LAN connections first (laptop -> Ant), then Network -> WWAN -> Scan -> Connect -> set wifi password etc. -> save and apply -> and then go to interfaces -> find WWAN (name of the wifi network) and click Connect

What kind of improvements do you see from adding a 2nd fan?

This is the info from my Network page. Any ideas?

Tried it several times :/

My Antminer wont mine..

I finally got it to connect to my wifi, but it wont start mining. I have tried several pools but it wont start.
When I add my pool-info the 'Applying changes' info is stuck at '/etc/config/cgminer ' is this a problem? The pool-info seems to change fine anyway.
Also changed the NTP-server IPs as someone suggested.

plzzzzz halp

Reboot.   It might hang.  Then power off and on again. Then log in

Hiya,

My antminer was hashing along fine for some days and suddenly it started beeping once a second.
I`ve tried to switch it on and off, the beeping has stopped but it isn't hashing now.

Also, I couldn't get into the configuration menu anymore.

Anyone know how to fix this?
I really hope it's not broken or anything
