I was bit surprised when after modyfing cubes per youtube video (anyone did put heatsink on all DC converters?) and applying new thermal paste I managed to get my problematic dies to work at full spead. I had 2 that would run at 125mhz max. now they running at full 300mhz (didnt tried more).
and was shocked how dried up thermal paste was on some cubes:/
btw anyone ever tried to put some water cooling?
I watercooled both a Jupiter and a Nepturd.
With the Jupiter I fit
FOUR ASIC boards,
TWO controller cards, (so I can run it as 2 Saturns if I want to)
TWO 760Watt PSU,
TWO water pumps,
THREE fans,
and the 360x120x60mm thick radiator
ALL inside a standard Hoopiter case.
You have to click the links below, I only post links.

First pic is during initial construction.
The water loop is running but only two ASICs are watercooled.
The three uninstalled waterblocks are sitting there waiting for assembly.
They are already part of the loop and have water running thru them.

I used a tall Thermaltake water resivoir.
I also left an opening in the 220VAC outlet box for small children to stick their fingers in!
The two 2000 Watt PSU that make my 4000 Watt rail can also be seen here.

http://imgur.com/9T8lRc2I used two 360x120x90mm thick radiators for one nepturd.
http://imgur.com/5TktL32I might redo the arrangement of my ASIC PCBs so the water and everything is in the center of the pentagon.
Then I can cool the DC/DC with a smaller fan and make a case with lower cost of materials.
I think I can use 1 fan for both PSU and the DC/DC converters.
I figured out how to easily watercool the DC/DC converters but never got to it.
(2 years later I doubt I will ever get to it)
For both of the designs I used two water pumps in series so I would still have flow even if one pump failed.
I also have a smoke detector that lives right on the miner rack.
A titan uses the same form factor so my mods would also work for it.
YMMV
