Well after a week in the DC, I can clearly state these tubes SUCK!! total junk!! Unreliable heat MONSTERS!!
Out of 40 boards 10 are severely under performing and I had 1 start on fire today. Now to see IF the RMA process is as botched as the sales process. Angry

sad to see that.

I added second fans right off the top my set of 2 runs great. overclocked and all

they need two fans and very good psu's. they will run very nice with this fan added

or this one

one with the silverstone and the other with the delta

here is the ~~silverstone~~ delta

~~delta~~ silverstone

these fans move a lot of air and with the stock fan pushing you are really moving air.

notice my handles do not turn in they face out. this helps to cool more.
Not to disagree with anyones instruction or build or design.

I tested quite a bit and handles turned out keep more hot air out of the chip area. the second fan really helped me with hashing I get a constant 1690-1705 for 2 units set on freq 280. I would say that the second fan is a gain of 80-100 hash for 2 units combined.
I have a few deltas if someone wants them. I can fit 3 in a medium flat rate box. LOUD

What's your inflow/outflow temps? I have a silverstone as you suggested and another fan I had sitting around going now. Removed those noisy stock fans. Outflow temps dropped 2-3C with dual fan over stock so I am hoping all is good.

EDIT: My outflow temp is about 45C; gets up to 60C on the metal casing that exposed to the outside. God only knows the chip/inside temp.
