I believe the blinking red light is described in the Kernel Log as "error_fan 4, normal_fan 2, fan_num 1". This error was showing up every 10 seconds in the log, but seems to have spontaneously stopped for the last hour and the red blinking light is off and now the normal green blinking light is on. I still think the miner is pulling too many watts. And I'm curious if others have the large difference in RPMs between the two fans. I described the issue to Bitmain in a support ticket. We'll see what they say.
my fans are 4200 and 3960 right now. 4h39m46s 4,837.35 4,634.77 temps about 50 will be able to put a killawatt on one tomorrow

Dammit, I want one. Has anyone run ROI through a calculator based on ~$.10kWH?
I can go do it, but if someone has it off the top of their head...
Try this one ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) I would rather use bitcoinwisdom calc https://bitcoinwisdom.com/bitcoin/calculator

BITMAIN, has always given me good service with defective rigs I've received in the past. Keep us updated please.

At $.10/Kwh, I don't think you break-even before the halving in 2016. Unless of course Bimtain delivers YOUR S7 for say $1500, or maybe they limit deployment of the S7 (i.e. sales), or maybe Spondoolies delays deployment of the SP50 until well into 2016, or maybe BTC price goes up to $300 next week and stays there (or above). Just keeping adding enough parts to an optimistic scenario, and I am sure you can make it work out! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

If you assume, that you can resell your S7 in a year for 75% of your primal purchase, you will ROI pretty fast ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Just my thoughts.... ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif)

You are absolutely right you will almost certainly have to sell it in order to break even. I would argue you will need to do that well before July 2016 (approximately), when the BTC block reward is halved.

I did use UPS so maybe that will help.
Forget about UPS ! I'ts a mess. They don't even know themselves when my package will arrive. For more than 24Hrs schedule-delivery is not available. The package should originally have arrived today (Friday) It looks like they are generating status updates randomly with no sense. May be it's lying on the ground of the Ganges. The Weekend is coming, so the next earliest possible date is Monday. (1 Week) This is very disapointing. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2F91.201.57.202%2Fphoto%2Fwebapi%2Fthumb.php%3Fapi%3DSYNO.PhotoStation.Thumb%26method%3Dget%26version%3D1%26size%3Dlarge%26id%3Dphoto_555053_5550532e4a5047%26rotate_version%3D0%26thumb_sig%3D2f766f6c756d65312f70686f746f2f5550532f5550532e4a5047%26mtime%3D1443162283&t=665&c=_vLq5A_k1PuaRA)

What im wondering sense there is none up for sell on the site now
which is unlike them or is normally unlike them even for a batch one .
did they make what they wanted at this price ?
over the S3 or S5 price ?.
Is Spondoolies-Tech's new miner coming a worry to them and they are holding posting any more for sell etc etc ....
or is the price going to drop they know they have a lot of back lush to deal with when they do they need to think it thu .
or that's it for batch one ?
or batch one was just a test run to see if that price would work ? .
and a bigger more expensive one is coming in batch 2, because of Spondoolies-Tech's new miner. seems strange when Spondoolies-Tech made that announcement they went off sell .
Thy turned from seeming to care into a big business way, not many personal inter action on the forums any more etc etc . Ive noticed unless you pay them a lot which is normal for big business, I'm not upset that's just how it is .
Just my out look , I'm not trying to start anything or be disrespect full , i fill let down at the price.
Yeah, well Bitfury has announced their 0,06 J/GH 16nm technology, so that will get interesting also. Then there comes 21 with their 0,16 J/GH chip So it will be getting interesting in here ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

Batch one was already sold out a few days before the announcement by Spondooliestech. The SP50 has nothing to do with the "sold out" announcement of batch one. Bitmain, is a straight up company and much appreciated. At least by me.

I was going two buy 2 s7 at least but the price stopped me .it's more a disappoint meant to me then anything for the s7 price.

I always FedEx my shipments from Bitmain. The thing arrives in 3 days from half way around the world with zero issues. Course I haven't had the thrill of being spot checked by customs, but that's a risk everyone takes.

[/quote] KnC and BitFury both are only going to sell to the public inferior products that they are basically bilking you on when looked at in respect to ROI. The reason is simple. Both have to satisfy investors and have massive mining facilities of their own they are operating. IE They are going to mine and sell the bitcoin themselves, cause a difficulty explosion and walk away with the cash. Their silent unknown backers will demand it. And since they are using THEIR money, they (KnC and BitFury) really probably don't have a choice in the matter either. That's assuming they 'disagree' with their investor's positions. Which I do not believe they do. These companies are going to start tech hording like building ICBMs and nuclear warheads. Then the cycle almost works like the world today. The countries that have nuclear weapons get damn near free reign over the ones that do not.

At $.10/Kwh, I don't think you break-even before the halving in 2016. Unless of course Bimtain delivers YOUR S7 for say $1500, or maybe they limit deployment of the S7 (i.e. sales), or maybe Spondoolies delays deployment of the SP50 until well into 2016, or maybe BTC price goes up to $300 next week and stays there (or above). Just keeping adding enough parts to an optimistic scenario, and I am sure you can make it work out! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Break even is for me right now 256 days out including power costs. Think that puts me right AT halving. But no one knows what the difficulty increase will be once these things saturate the market and the extra KnC and Bitfury facilities they are building come online. Ultimately through tax breaks, loss taking, and other accounting gimmicks (all legal) is the way I'm going to be lowing my ROI quite a bit. Then we got the final sale of the machine itself. I have 3 S5 units right now. I'd be happy to dump them for half my purchase price to 33% of purchase price (in 2016) as long as the other party pays shipping. Then get another S7. Time for work now ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) .

They have to much time on their hands if they are x-raying miners. Seems like opening a box or two should confirm it. I really don't like my local DHL. It's the service I avoid. But some claim they work great for them. [/quote] I have used DHL on my S3+, S4, and S5 purchases, all have arrived without any issue. I personally use FedEx for all the other shipping I do. I cannot be upset that customs wanted to check out my package. Regardless, it is now in Miami and out for delivery ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

+1! I've had good experiences with FedEx too. My first S7 order was exactly like this. Took 3 days and was delivered before 10:30 AM, just as FedEx said it would. No delays and no drama. Of course carriers are like hard drives manufacturers. Everyone has a different favorite because of personal experience.
