It's super quiet so it won’t mess up your workspace and even makes for a decent gift. The package comes with a USB cable and power supply, but you’ll still need a power cord.

Is Bitmain still applying thermal paste with a pneumatic butter knife?

They're usually very good with thermal paste, if you see S1-S4 chip pics, they spend the time to paint each chip individually. I'm not sure what happened on this one, but it was impossible to clean with all the resistors so close. Was either going to be goop or cloth fibres, and the goop was there first.

I think the only other thing to try would have been something like a long nylon cleaning brush from an electric razor dipped in alcohol. Still tricky though.

any good recommendations on images for raspberry pi controllers to run these?

Minera, Raspian

Annndddd...bookmarked. I just purchased an Antminer U3 to test the waters, this guide is comprehensive and easy to understand. I wish I could tip you.

You can, but its not required by any means!

[Slight necro, was accumulating U3 feedback from all the threads]. That's a good point, I'll find some micro brushes to buy. Can douse them in articlean and work out the paste.

Any good recommendations for a raspberry pi based controller that supports the U3?

Raspian, Minera, MinePeon, anything that will get you cgminer.

I am familiar with minera for Gridseed devices but was unable to get it to detect the U3 I was offering this as a suggestion for a future guide from you if you had time to put together a setup guide for Running the U3 off of the Pi to expand off this setup guide. I have also tinkered with Minera but the latest build has an outdated cgminer and wont detect the U3 and the bfgminer works but only hashes at 4GH. I am still tinkering but no clean off the shelf solution to run a Pi with the U3 yet without some tinkering

I still go for Raspian because its essentially just a linux environment, so you can put whatever cgminer you want on it. There are obscenely long instructions for that in the Noncetech guide if you want to go from scratch, although other users may be able to provide nearly complete SD card images for Raspbian.

after some tinkering i got minera to work with some ease. Minepeon is to outdated to work with the U3 out of the box for anyone else looking to run these on a pi go with Minera and change from default of CPU miner to CGMINER on the latest version 4.0.0 works with only those changes

So how quiet are these miners? (can not find any video with this miner) im only after quiet miners. i did see that Bitmain came out with a new design on them.

It looks to be exactly the same fan, so it then depends on what your definition of 'silent' is. To me they're as quiet as ambient, but its personal opinion.

These new ones should get a little more air because of the new design maybe run a little colder and fan speed may not need to be so high. its just a thought...

I got a brand new U3 straight from Bitmain over amazon.  Have been fiddling with it all night and can't seem to get it recognized by CGminer.  I have done all the steps and don't know what else to do?  Any ideas would be helpful. My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385) I downloaded CGMiner 4.9.0 and made a notepad file with this in it... cgminer.exe  -o us1.ghash.io:3333 -u DebitMe.U3 -p 123 and saved it as a .bat file in the cgminer folder. My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller" When I start CGMiner it says "No Devices Detected" What am I missing?  It seems to be recognized by my computer, but just not by CGMiner.
