I'm using a normal 80mm computer case fan (12V@0,02A) with a 7.5V AC adapter and I guarantee you that it is quite noiseless.
I'm just waiting for a power adapter for my hub and I'll put all my BE's next to the Ants in the same hub, and then, put them on a "shoe box" to properly manage the heat and create some tunneling to improve airflow and have it neatly arranged.
But let me ask you: besides the noise, have you already tried to use 0981 frequency and a fan? even for one hour.
That way you'd check if it is some heat issue or not.
And you might have some USB Hub lying around that you could use instead the extension cable?
These are just some ideas to troubleshoot your problem.

Thanks for your advice, I will have a look into the hub and fan options, I dont have either to hand though. I just liked what chromosoma had done with his set up on top of that ali heat sink, I could acheive this quite easily and cheaply so I thought that would be the best way to go. I've been looking into the different thicknesses of thermal pads but can't really find any solid information on what thickness to go for.
I've been running it for about 25 minutes on the 4F02 setting, it's getting 4.8% HW so far.
I will try relocating it using the extension cable when that arrives and see about getting hold of a fan to see if I can improve things. Thanks again
BTW
Running at 2 GHS at chip Temp. just 40 C° (room temp 21 C°)
Passive cooling FTW=)

Do you have a link to those thermal pads, and do you know their thickness, and thermal conductivity rating (w/mk)? Thanks
I second that: Get a fan and cool the Ant miner down.
Look in here: https://bitcointalk.org/index.php?topic=7216.0 for plenty of examples using BE's and other miners.
Also look earlier in this topic.
You don't need any special heatsink under the 2.2gh/s.

The only thing that might be an issue is the noise from a fan due to the location of the setup, if I can get the same level of cooling from a heat sink I think I'd rather do it silently.
I think some of the issue may be due to the fact that it's plugged into the USB port directly and is chip side up, so the heat sink is below, perhaps this is meaning it's dissipating the heat less effectively. I've ordered a 1m USB 2.0 extension cable to allow me to reposition the thing.
Here's the result after an hour of 0581 mining:

As expected hash rate but worse HW, up to 5.36% now.
Don't worry about the 5 second rate, it's the long term rate that matters most.
It is safe to experiment with the speeds so long as you have some cooling. Try from the lowest speed first, then build up and see what happens.
Give each setting plenty of time to stabilize before trying the next one. If you go above 2Gh you will probably need a powered hub to supply the extra current.

OK thanks, I've just restarted it at 0581. I'll run that for 24 hours to see if it brings the HW rate down, if it does I'll leave it at that until I've got a decent heat sink for it. I'm looking to salvage an old CPU heat sink or similar from somewhere and just get hold of some of those CPU pads as the go between
You have a quite extreme hardware error rate...!!
Thanks for your quick reply, is this most likely to be down to...
cooling?
lack of power? (I'm sure I read in this thread somewhere that normal USB ports dont provide enough power by themselves and they should be put through a powered hub? Are yours in a hub?)
or should I try running it at 0581 or even 0781 just to see if it changes the HW rate as it is? What do these things run at if you dont specify a frequency?
I've also noticed that the speed fluctuates regularly, although it's averaging at around 1.363gh/s, watching the (5s) in the top left hand corner, it drops down to 600-800 mh/s then up to over 2 gh/s, should this remain relatively static or is it normal for it to fluctuate like this?
Another thing to point out in case it's made a difference, is that there are two versions of cgminer on the link from the pdf guide:
https://github.com/AntMiner/AntGen1/tree/master/cgminer
And I'm using the newer version - cgminer-run-windows-20131224.zip rather than the 20131222
I've been running my antminer for about 24-hours using the following instruction:
cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://mint.bitminter.com:3333 -u user_worker -p 123 --bmsc-freq 0681
Does this look healthy to you? I should add, it's not plugged into a hub or anything, it's straight into the USB port on the front of the PC.
I'm considering running it at 0781 once I've got a heat sink and CPU pad to put on it, any thoughts on this appreciated, thanks

forgive me but shouldn't that be
(QUANTITY )X 0.0775 +(SHIPPING) 0.02 = Price
1 X 0.0775 + 0.02 = 0.0975 ?
mabye its just a typo. but you might wanna double check.
Ah sorry, thankfully just a typo on the forum not in making the payment. Thanks for the heads up:

Hello all, I've just entered the world of Bitcoin, these free sites are a great starting point.

As an update to the list on the first post, it looks like bitcointree and btcflow.net are down. Before they went down for good I think it came up with a message saying all their bitcoins had been stolen! How sad, where's there's money there's greed.
