these look like they will compete with the sp20.
I have a new evga 1300 g2 waiting for my test demo
I have this fan :

I believe it will be the best possible fan for the s-5> If the s-5 is like the s-1 or s-3 this fan will make the s-5 a quiet miner.
The real key is how the s-5 is with the new pcb board. If it runs as stable as the s-3 did.
It may take over the sp20's title as the best home miner.
I am excited to do my review.
I will do it with 3 different psu's that are all quality.
the evga 1300g2
the seasonic 1200 plat
the seasonic 760 plat --------I ordered new cables from Cablez to use with the seasonic psu's.
lastly I have lower quailty psu's
To me as a miner.
My gut tells me we will have two quality machines available affordable the s-5 or the sp20.
Both have a shot to roi . it will be nice.
