I have been speaking to Yoshi about S4 issues but wanted to get an opinion here since I imagine he is not working on weekends.
One of my units is being shipped back because something burnt. It also had an issue with Fan#2 which is what I posted about earlier.
Looking at my second unit I noticed that Fan#2 in this unit only runs at 240 RPM and the others are about 4000. What caught my attention is other screenshots showing fan speeds and Asic chain temps that are close.
My temps are
chain 1 60
chain 2 48
chain 3 60
chain 4 51
Both of my units have been like this since they arrived. It seems odd to me that both units behave the same way. Anyone else having similar issues? Is there a Fan#2 issue?
BTW - temp in the hashing room is 22C.
I made 3 orders of S4, 1 was for 4 units and 2 for 1 unit as a test for various reasons....6 in totalOne of my units is being shipped back because something burnt. It also had an issue with Fan#2 which is what I posted about earlier.

Of the 6 units, 4 have dead intake fans (3 were front left and 1 front right) all seeming to die within a week of each other...and 1 has a dead hash board....Im calling in for warranty tomorrow and am not impressed to say the least....
Of all the miners Bitmain has come out with I think S4 is the biggest piece of junk of them all....all the machines vibrate and are not put together with care as seen by the lack of thermal grease, and the fact that 2 power posts broke off while tightening them by hand speaks for the lack of quality....
Last of all...whats this about second handed all of a sudden....don't insult your customers BITMAIN I don't see how my NON-SECOND HANDED S4s ended up with marks from the mounting brackets...please
I almost laugh but just shake my head seeing PetaHash of now worthless miners available from a company who had no stock to ship for the 2 months while the difficulty more than doubled...anyone remember august? Greed at its finest....keep mining Bitmain decentralization is that 1PH at a time ....
