what is the diameter of the S7 fan ?
i want use a duct adaptor for 2x 200mm fan (high flow, high pressure, low noise). Cool

the square fan does not fit into a 6 inch duct.

the square fan does fit into a 7 inch duct.

read my thread on how I fit the square fan into a six inch duct. wait for link

Didn't we all go through the Sesame Street triangle peg / square hole .... round peg / square hole ..... square peg / round hole ( although one of my daughters friends just might like that ) .....

it all comes down to the size of your hammer... Shocked

The s-7 is better then the s-5 And depending on your setup there are mufflers that work.

I disagree.
To me 1 x S7 is much louder than 3 x S5's. Even with fan speed reduction to 30%.

That doesn't really make sense. Your S7 = 2x fans and S5s = 3x fans, identical fans.

Sound is not merely relative to the fan speed and rating.
You also must factor into existence the flow of the air and the noise generated from turbulence and or vibration.
So you have environmental factors to think about.

S5 - has lower restriction of airflow.
The fin design of the heatinks allows for air to pass through with less resistance and turbulence.

S7 - has compact heatsink design and completely enclosed aluminum housing. This creates a lot of turbulence and resistance.

Just like water. What generates more noise, a river without rocks/rapids or one with rocks/rapids?

Keep in mind not all S5 are the same. I have units with 4 different types of heat sinks. So it is important to know when compare which models people have.

1. The standard curved fin
2. The new ones like on the S7
3. Some CNC'd flat ones simliar to #1 but no curves
4. I forgot but I am pretty sure I received 4 different kinds from Bitmain

New S5's with S7 heatsinks, are you talking about the S5+?

And also there were batches with mini heatsinks individually on each chip. I'm considering adding some to the hotter chips since i have the materials for it but i'm not sure if it does anything at all, would be good to know. It Works for the S7, not sure if it would work with a S5.

They look like the same to me, but I do not own any S7's so I am only going off of pictures. I am pretty sure they are the same. I can take pics if you want.

dude you really serious?
i have had a couple of s5 before they came with fan control and even changed fsans for s3 to s5 and they were ten times louder than my s7 at 23% I have them running on outside air heating the house. aboout 50-60 degrees
perfect temps nice heater.

well sunny you and I agree that the s-7 is easier.

Right now it is 77f in NJ pretty hot for OCT.

my s-7 is running at 4740gh and freq 587

I use my muffler system set the fans to 33% and basically it is quiet well under 50db.

See thread link.

https://bitcointalksearch.org/topic/m.12500685

Now if it were 90f outside I would have issues wit heat but even at 77f I am far more happy with my s-7 for sound then I ever was for my s-5's

Great analogy, but not applicable here. The S7 is hands down significantly louder than S5s. Shocked anyone who has owned them both could have a different opinion. I would go as far as to say my S7 is louder at 60% than when I had multiple S5s running at 100%... That being said, the S7 stays significantly cooler and is obviously a better design.

I say everyone has a different pair of ears. The pitch of the s-7 may sound worse to you.

But the s-7 is far easier to manage sound wise then the s-5.

Just for curiosity sake, I took a decibel meter app (iphone) and tested.

3 x s5's generates decibel ratings of 72 at full hash.
1 x s7 generates decibel ratings of 83 at full hash - auto fan.
1 x s7 generates decibel ratings of 74 at full hash - fan at 30%

LOL .... You should hear the stack of jet engines I have...

fan cooled stuffz in the rack:
4 Antminer S2's fans on auto, but at 100%
2 Antminer S5's fans on auto. but typically around 75%-90%
6 Delta Electronics DPS-1200FB power supplies
2 Dell Poweredge 850 servers
1 Dell Poweredge 1950 server
1 APC 3000 UPS
1 Brocade fiber switch

when I'm in my workshop at my desk, I'm 3ft from the rack....

The Antminers create the air moving rush sound.... but the power supplies create the high pitch turbine sound. I have yet to take my Db meter and audio spectrum analyzer and measure the ruckus that rack makes. My hearing is already going ( too many damn kerbbOOmm's near me in the past ) so the noise isn't sooo bad ... for me anyways.

I am pretty sure they are standard 120mm frames so you just need to figure out how to square down your adaptor to properly push the air through the heatsink. It should help with the fan's noise, but not so much with the air turbulence noise.

Phil really made a difference with the noise with mufflers, could be something worth looking into as well.

In any case, it might be unhealthy to be close to multiple S7 (he had 7 running) without any kind of hearing protection.

Right, and since I'll only be pulling 1200 Watts vs 1800 Watts, I would assume it would be the sound of 2 S5's, or thereabouts.
