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.
Well if it has 2 blades, and it has S7 compact heatsink, i would like to see it, yes. If it has 3 blades, then its the S5+ i know. Regardless i believe you but yeah, if there's S5's non + with a S7 compact heatsink, i would like to see it + know what PCB version it read on the top right of the PCB under the bitmain logo. The latest i saw was v1.91.
