Hi Syke,

Thank you for the review posting!! Cheesy

I understand you're imitating our marketing techniques, but why did you copy the miner loudness ? Grin

So SP, does that mean since everybody is copying, you are going to lower your price and actually report your SP20 as a 1.1-1.3T miner?

The airguides on the fans aren't a sign of a crap fan. They are designed to help shape the airflow and make it more laminar. It gives some of the benefits of a counter-rotating fan (like the Delta GFBs) without the added cost.

If you have time, use a smoke machine and look at the flow pattern of a standard fan vs one like this or the Delta FFC1212DE. It's pretty interesting.

Does anyone else here have a 50A+ adjustable power supply? I'd be interested to see some efficiency numbers in the range of 9V-14V.

Syke thanks for review. does your stock fan look like mine?

case is 38 mm but blades are 25mm?

Yeah, it's the same weird fan. Works great but sounds awful.

12 hrs in and it is rock solid at 350mhz doing 1155 GH/s with 120 V and a hot room. There is no difficulty running this thing at spec as advertised. Temps running a very cool 63c.

My SP20 peaks at about 1500 GH/s under the same conditions.

server psus and cables..... Similar to SP20 draw per cable? I wonder if anybody has taken any readings yet.

Both miners have 4 power connectors. The SP20 can draw significantly more power per cable.

4 cables at the kwatt meter = 552 watts so 552 x .92 = 508 watts / 4 = 127 watts at the cable.

it must use 4 pcie cables 2 are not safe.

I am at freq 231. I will test faster in 7 hours or so . time to crash. I am tired.

Would I buy these yes , but I know I am changing out fans.

If I do buy some.

@ bick

is the sp20 not as loud. if you down clock to better power numbers like 1000 to 1300gh it is better for sound. I can spend $0 extra money on a sp20. but I can't see that with the s-5.

Now all of mine are in a home that I share with the wife. We will be able to sleep tonight with no noise issues since I swapped out the fans on the s-5. I am running 7 underclocked sp20's no extra money for sound mods need . Just down clocking.

For most of us that buy it the game with the s-5 will be what is the cheapest fan replacement that allows a good clock and decent sound. I spent 27 for the two fans. 10 on ebay for the delta and 16 on amazon for the silverstone.

Thanks judypug... simple retro fit for S5s not a bad way or SP20s. I used to own 2 SP30's brilliant machines and sold them after they worked flawlessly for a month. Need to discuss this with my guy in Norway. Seeing as he will deal with this issue not me as the datacenter is on his turf.

WOW! Loud.

Interesting.

Thanks for the information. Does that mean by comparison the SP20 is quieter?

To an untrained ear I would say they are comparable. The S5 has a higher pitch.

yeah but the pitch is brutal on my ears.

now when I underclocked to 250 the fan went to 3600rpm vs 3800 rpm.

maybe antminer can allow for lower fan speed if you clock to freq 250

I have some more tests to do. full speed of freq 350

plus an over clock to freq 375?

1 more fan due on the 31st

I have a 300 watt psu that allows for volts to be adjusted to 10 volts.

I could do a board at freq 250 first at 12 volts then at 10 volts

compare to a board with a solid 12 volt atx eff of 90- 92

with careful testing and scaling the numbers I should be able to see how undervolting works.

still getting 1128 gh with freq 231

Edit from other thread:

Quote from: philipma1957 on December 29, 2014, 10:58:42 PM

Okay just got back home from a party. I need to find a few other fans.

at freq 250 I do 824 gh and 404 watts that comes to .49 watts per gh.

I bounce to 416 watts which is .504 watts per gh this is good.

It will run too hot with my current fan setup if I go above freq 250. temps are 60c and 57 c

It is too loud stock! it runs hot at stock speed with stock fan. stock fan ramps to 3800 rpm and temps were over 60c for each board.

if you want db's 75 plus it is a nasty pitch.

my complaint is really simple here 2 silverstone 140's would allow it to run max speed and quiet. A no brainer 1 minute mod. instead I will need to fuck around with it.

If noise does not matter run it stock. It is louder then the s1 or the s3 it is as loud as the asic miner tube. So far at 225 ,250, 275, 300 and stock 350 it scales close to .51 or .52 watts

per gh. I am looking at the stock fan and it is a bizarre fan. It is 38 mm yet has 1 inch deep blades I have never seen a fan like this. I have to go back and correct part of the review.

3 shots of the my wife will kill me sounding stock fan. it has 38mm depth with 25mm blades then 13mm focus grill. it was pushing 3800 rpm at freq 350 worse sound of any fan I ever use for a miner.

When you say it is loud, is it louder than an S3 or quieter? Thanks for your quick review.

it is far louder then the s-3.

I am philipma1957. I went to my other pc this only allows my backup account.

the s-3 is nothing compared to this.

if you want this in your house it will need fan mods.

In a shed or a barn no big deal

67 or so DB? Like a truck driving by or your boss telling you to get off Bitcointalk again.

no 75db at one meter
my 2 fan swap dropped it to 60db with better pitch.

I boosted to freq 231 good solid numbers

552 watts for 1120 gh that is better then .5 watt per gh

I don't know what these fans will allow safely but 1120 is good for now.
