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.

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 Smiley

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.

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.

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.
