Okay i started with 3 600 evga bronze, ended up melting pcie wires on all three. Returned them and got 2 rosewill 700 capestones and a rosewill 650 hive. I have 2x 700 and 1 x 525 and 1x475 monarchs. The rosewill 700 psu were running the 700s fine until the liquid started coming out around the waterblocks the 525 the same way. The 475 monarch i really never got to run only hooked it up when the 700 quit and before it really started hashing i noticed alot of liquid on the sled. so i stopped it. I have a 700 that was working fine, cut if off wanted to inspect the two that were messed up. the screws on the back side of the board that are holding the waterblock were real loose. I think that is why they were leaking. But the psu work fine until attached to the card. Shit even running the fan only they work fine, as soon as the pcie cables are add it will not come on. When i get home from work im going to mix and match all psus to monarchs but i dont think its the psu. When they were working they ran 80c and the 525 was usually around 55-60c. Ive got them in my garage because of the heat so its probally about 75-80 f there. http://i.imgur.com/P669rKH.jpg. excuse the mess made a room on the other side of the wall and at the time i hadnt finshed. Im running them in that box. with a desk fan pointing down on them and the window fan on the top in acting as an exaust pulling the heat out of the box. Filters to catch dust, dirt on the front. Ive emailed the reciever and bfl and sent rma but i dont know if anything will come of that.

Hm. Hm hm hm hm hm. Let me think about this one: That's all sorts of good data. So not too hot around it, they didn't boil the coolant, loose screws. 80c temps on the FETs (not bad) and water as soon as you turned it on for one of them.

The reason I'm thinking about the screws is because when I picked up my Monarch that fell off the sill this morning I noticed the screws that held on the fan and the front of the plate to the standoffs were loose. Snugged them back down, no biggie, but they were all snug when I got it. Maybe a bit of vibration over time wiggled them loose, the back of the board is on the plate with self locking bolts, so those are not going anywhere.

So the little tiny screws that held the sink to the board on the back were loose? How loose, not *super tight* loose, or *easy to screw and unscrew* loose? I'll check mine later on when I get back there.

Is it possible that over time the heat may have expanded the material that the screws are set in? I recall when new homes were being built in the 80's/90's, drywall screws were popping through the mud affixing the sheets due to the green lumber drying over time. It's that that I envision the screw holes becoming larger due to heat, thus allowing the screws to slowly working their way out due to the constant, albeit slight, vibration.

Duly hope the above helps, guys. At least something to consider.
