Coupons were offered to customers who bought S7 Batch 8 and the order has been paid till Nov. 30, 19:00 of Beijing time. Please kindly check your account if you've already had Batch 8 order I am sure to those that bought Batch 8 the coupon is appreciated, but there was to be some compensation for late orders on Batch1 along with the low hash rates of some of the Batch 1. Is this coming soon?

Coupons were offered to customers who bought S7 Batch 8 and the order has been paid till Nov. 30, 19:00 of Beijing time. Please kindly check your account if you've already had Batch 8 order checking...coupon is there ! 150usd coupon. Well thanks Bitmain. But i'm a bit confused. I paid 4.73btc - which was around 1500usd at the time, or 1550usd I forget - now the price is 4.45btc, but around 1650usd. Now I know we can argue btc = btc, but if I were to buy an additionnal s7, it would be with fiat so the cost for me would be 1650usd. minus coupon, 1500. and these are shipped at the same time ? Maybe i'll wait...if btc price goes back down 50$ then the coupon would be a good deal └(°ᴥ°)┘

I got an email from BITMAIN that my order is paid and preparing for shipment.
Its Batch 8 :-( but I paid 1557.55 for it (excluding DHL 44$)
This batch is the worst in terms of efficiency... 700mhz with 135 chips
My first 3 x S7s are very hashing well - except for one unit with a "woooo...wooo..." sound coming from the intake fan.

Did you try easing the screw(s) just a little-this seemed to help many. I would look at it and see first if they are so overtightened that fan plastic is a bit distorted (I have seen it), then would start with just one screw at first (quarter of a turn or even less), then do the direct opposite, then proceed with other 1-2 if needed. I had to ease just one fan screw on B1 for it to stop making a similar sound.

I recall a post that "just stuck a piece of tape" to fix it, .... but still no cigar Now, I have reduced the fan to 55% and that kind of eliminated 95% the annoying sound - that fan speed gives me about 65-67c during day and 59-61c at night.

If I hold my hand up kinda close to the back fan the sounds stops. So some kind of rig for that? Mine are in a datacenter so it can woo woo all day. I used to put a gutted 120mm fan as a spacer between my s5 front fan and the chassis with 90mm screws. Also put little spacers between the front grille and the fan giving about a quarter inch of space all around the edge of the grille. Quieted down the s5 a bit. Fan is more efficient also. The fan is really too close to the chassis on the s5 and s7. So maybe a spacer between the back fan and the chassis?

The fan is really too close to the chassis on the s5 and s7. So maybe a spacer between the back fan and the chassis?
I would agree with using your hand to investigate. What I did was use two fingers extended out over the edge over the back fan and the front fan. I would move my two fingers (index and middle finger) around the edge in a circular motion until my fingers were at a point where the noise was no longer audible. Once I found the location where the air being sucked in was no longer audible, I placed only one finger (my index finger) over the same spot and the sound was still no longer audible until I moved my index finger to another location. So, I was able to find the "sweet spot" to place the tape on the grille of the intake fan in front. Every rig does not have the radiator type heat sinks in the exact same location on every chip. Some could be off or aligned in a certain way after manufacturing that allows for a whistling sound as wind is sucked in between the fins of the heat sinks when they are positioned just right. Since every rig does not have heat sinks in the exact same location and the exact same size [varying by thousandths of an inch]... this whistling noise is audible only on a small percentage of rigs that have these heat sinks aligned just right to allow for this audible noise. This is why I feel a small piece of tape is sufficient to reduce the amount of air across particular heat sink(s) causing the noise. I noticed one miner had placed a piece of foam on the shelf in front of the fan to reduce the noise because that just happened to be the location on his particular S7 where heatsink fins were aligned just right to allow for the whistling noise. The location of where the wind rushes in across heatsinks will vary from one rig to another more than likely.

It would be cheaper for you to get your Antminer's hosted.
