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,
