2s3's or 1 c1

[rkinnin]

I am looking to expand my farm....

From a daily expense factor and/or mining result which is better?

Two s3's
Or
One c1

And why did you choose that answer!

If you have very cheap power the s3's are pretty good.

2 of them can do 1000gh and 800 watts

[mavericklm]

quiet? c1
better wattage? s3
more hash? c1
overclock-ablility? c1
faster webguy? c1 also less beeps than s3
....

also if u are handy you can use c1 to heat-up water for different usage!

It depends on the C1's personality.  If it does not need rebooted much and runs good I would go C1.  If they still have the syscooling pump I would replace it.

If it has problems then two S3's.   S3's are built like a tank.

Adding to others longevity, S3s seem to last longer than C1s.

I attribute a lot of this to original pump.  I have had no coolant issues after switching from syscooling pump.

Syscooling was a horrible company.  I'm glad I don't see a relationship continue with them and Bitmain on other models.  I still have not heard of any other water cooling company that dry tested pumps.  Batch one pumps were on last leg when we got them.

As an aside from the pumps even, the high clock speeds of the C1s leads to dropped chips / dying blades quicker. Not necessarily problematically quick, but quicker than the S3.

All nice advice so far.

Which solution gives off less heat to the surrounding environment?

It all just comes down to watts. If their power usage is the same, then their heat production is the same. Liquid cooling or air, it all just ends up as warmer air (after having passed through the radiator on the C1).

[mavericklm]

Which solution gives off less heat to the surrounding environment?

2 * s3+ should give less heat! also 900gh/s vs 1000gh/s

I would say it depends on what freq you S3+ is on.  I know I had a few that hit 500 with freq up.   I overclocked them during winter.   

The C1's I don't notice heat as much just because of a big fan pushing the heat outside currently.  But both get hot if you are running 1T with 2 S3 + or 1 C1.

stock vs stock!

don't want to think about ovk because it gets more complicated because each miner is different, even with the same model miners....

[Amph]

a proportion between the two tells to me that

1008gh/s : 806,4w = 880gh/s : 732w

so we are looking at 1.25 versus 1.20

c1 is 1/24 better, based on this i'll go with c1, i like also to have 1 powerful miner than many less powerful one, just because of density...

Aren't the C1 and the S3 based on the same BM1382 chips?  The power consumption is going to be the same from a watts per GH perspective.  As far as how much space things take, with each C1 you've got a PSU, miner and water cooling equipment.  With the S3, you can drive 3 of them from a single EVGA 1300 G2, compared to the single C1 the same PSU could drive.

Honestly, it's a tough choice.  My opinion is to go with the S3s just because you don't have the added headache of the water cooling.

Yes exact same chip's.  They take up a decent amount of space by time you set up them up.  They run at a much higher freq then the S3's. Below is a old picture of my 2 C1's.

This is within the first 2 day's of running as they still had syscooling pumps.

From a daily expense factor and/or mining result which is better?

Two s3's
Or
One c1

And why did you choose that answer!

S3's are pretty much bulletproof same as older S1's.

C1's seem to be problematic.

I'd go for S3's all day long .

[alh]

I have to agree with the recommendation regarding the S3's. They have a reputation for serious reliability, way better than the C1's cooling system. Also with two miners, you have the option of splitting your hash as you might see fit. Say across two pools, or maybe renting one on Nicehash/Westhash. If you really want to fiddle with a liquid cooling setup, then C1 is your choice. Otherwise I think it's S3 all the way.

C1's are fine after some tuing.  But I would agree S3's are tanks.  They take a lot less to setup and mine.

C1's are fun for a bit to play with watercooling.  But it's something I did for fun more then anything.  The only thing I can say for C1 that is absolutely better is the sd card being used on controller.  Makes it much harder to brick.

If you could find some way to run them in series... I don't know too much about water cooling and I never really got into the thermodynamics and fluid mechanics stuff... but if there was some way to hook up like 10 boards to a single pump/radiator then I could see the density argument.  Has anyone tried doing something like that?  Throwing 10 boards, a pump/radiator/fans/etc into a 4U enclosure?  I'm not sure if something like that is even possible...

They made a kit for 4 C1's to run on.   I don't think I ever saw a sell of it though.

I know I have seen two C1's in series, the nice thing was if one pump died it the other pump kept going.  So it's been done but not to a huge extent that i've seen.

I have had the original pump which broke down and let coolant out.  I would not put these into a nice enclosure, if something goes bad you will have a very mad data center.
