is there any info on removing the fans?

You'll need to remove the fan screws on the top, remove the screws on the botton that hold the 2 heatsinks together, then use a soldering iron with a small tip to remove the + and - wires from the circuit board.  They are easy to remove, just touch the joint with the iron and the wires will pop off.

Temps are fine, I'm still getting 0% HW errors.  Note only do this if you plan to run the units in Scrypt mode only.  If you run in SHA256, you will need the fans!

Also, Karanveer, am i shipping yet?

Yes seems like a single fan would do based on what Maxgen and Melmo have done.
Have paid the seller and will be updating tracking info soon

A couple of tips:  I noticed that the power supply has a switch on the side to select voltage.  I had been running with it set to 220V, and was only pulling 58 watts from the wall.  It was pretty stable like this at 850 MHz so I measured the voltage on one of the plugs and the power supply was only providing 10.8 volts.  After switching to 110V, I was reading 11.9 volts and power usage went up about 10 watts.

After doing the voltage mod, I'm running stable at 401 Kh/s and pulling 82 watts at the wall for my 10 units.

Melmo, you in Toronto?

I'd pay you to make the voltage mods to my units.

[MaxGen]

For the voltage mod, are you just bridging the pads with solder, or are you adding some resistance?

Also, from your last post, am I correct in assuming you are running the PS at 220 for the savings?  I don't think mine powered on at 220V

Thanks melmo

Sorry, I don't think I would trust myself to work on someone else's units because I'd be afraid of frying it.  Those solder pads are surprisingly small - I almost didn't do the mod because I was shocked at how tiny they were.

I tried bridging the pads with solder, but that wasn't happening so I used some very fine wire.  Tin the end of the wire with some solder, dip in some flux and solder to the pads, then trim.  I found some stranded wire and then used single strands - that's how tiny the pads are.

I'm running the PS at 110V now.  The 10 watt saving is nothing compared the other power-guzzlers I have

Thanks melmo,

I tried it on one unit prety much exactly how you said.  I have a lot of 30gauge wire lying around from wire wrapping projects.  My hands shake kinda bad, but was still able to do it without any damage.  The magnafier lamp was a huge asset.

I'll tackle the rest of them tonight.

Here's my single modified unit running.

[MaxGen]

Well, I did it on all 10 units.  took about an hour and a bit.  2 had cold solders but it was just a quick touchup to fix.

Looks good MaxGen!  What speed are you running at?  Does Scripta use cgminer or bfgminer? 

Maybe I should fire up my Raspberry Pi.

[MaxGen]

It uses a special version of cgminer.  https://bitcointalk.org/index.php?topic=482352.msg5305449#msg5305449

I've set the frequency at 950 by editing the miner-start.sh file.
