All the above ants have been cleaned and redone on with high grade thermal pads on the chipside and paste on the large coolblock
They all run nice and steady now, they keep perfect cool even though the ambient temps where pretty hot during last period
And we have 3 times S1 case with upgrade sets to S3 which are not build yet
I have no idea if they are better, since my hoster has no time to build them
They was delivered after batch 8 (S3+) was released but i expect bitmain not to send us the S3+ controller chipset
One of the boards of the S1 upgrade sets is going to be send for RMA to bitmaintech
I think its best done by someone who knows how todo this and has technical knowledge
For now i got one offer for 4 x S3 being 2.2 btc
These never been overclocked, the power supplies could not handle more load anyway.
