Mine looks like that too -- it was working for a day or two.  It was too loud in my office for me to even speak on the phone, so last night I removed the pull-fan fro one of my S3's and replaced the S5's push fan with it -- had to splice to extend the wires because they didn't reach.

Now it is nice & quiet, and still running at acceptable temps < 65

BUT chain #2 is dead -- all dashes :-(

How do I go about troubleshooting?  I reseated all of the power connectors (twice), and the two grey data connectors on top.  But I'm not sure what to try next.  My warranty is clearly null and void :-)

thanks,

Were there dashes before you changed the fan?  If not, then you can try power cycling the PS (off for thirty seconds or so) and if still a problem, lower the clock!

No dashes before -- all o's on both blades.  And it was hashing fine out of the box at stock freq for a few hours, then I cranked it up to 400 and it was doing about 1.3 TH nicely.  But so frickin loud.  That's when I decided not to leave well enough alone, and to replace the fan with an S3 push. 

Today its hashing on the one blade at 350 freq again.  And I can see the S3 fan is not going to be enough.  Its barely keeping the one blade at stock clock under 60 degrees...

I did reseat all the power and data cables I can see and reach from the top.  I guess a full tear-down is in order.  What was the good thermal paste again?

Good thermal paste. I never used it, but heard it was very good.
