This build started when my good friend offered me a spare Ivy Bridge-E chip, so this build is dedicated to him.
THANKS DAVE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That's all of the water cooling specifics, so on to the build.
I'll start of with a quick overview of the H620, since I don't think I've seen another build log with this case. In short, it's a decent case with lots of mounting options, but the 200mm options cause issues for water cooling. Basically, the holes around the radiator combined with the poor ventilation of a silenced case mean that in stock form a 120mm radiator will recycle some of the case air rather than pulling it all from outside.
So to help with this, I decided to make some radiator shrouds out of transparent plastic sheet from the hardware store. One 18"x 24" sheet was enough for me, and I chose to use the thinner 0.093" thickness. It's a little hard to see, but you get the idea.
The last image shows an extra bit of plexi I used to mount the pump and HDD since all of the cages were removed for the front 280mm.
On to the fun stuff, like an upside down mobo and general system install. I won't narrate too much here. I have an 8-way fan controller/temp monitor, I used four of those to monitor input and output temps from both rads. I'll go ahead and spoil the outcome, all four outputs read nearly identically (within 0.2 degrees Fahrenheit). I also used small bits of window/door insulation to seal gaps, but I doubt this really has much effect.
Next we have the completed loop. My logic works something like this: I wanted the gfx cards in parallel since they're very restrictive and aren't effected by flow as much as the radiators or cpu block. I added a second pump with the EK top for redundancy and added pressure. With the two gfx blocks in parallel they should be less restrictive than a single gfx block, but with all of the 90 degree elbows I wasn't sure of this. Since I was adding another radiator and a number of bends to my new setup, I wanted to up the pressure to get the best possible results.
As you can see in the above images, I've set the fans to intake from the top and rear and exhaust from the front. This is in an attempt to give the case positive pressure, with the top and rear intakes filtered the inside should stay fairly clean. The end result is below.
My final thoughts on the H620, it's a nice case but not worth water cooling in. If I take the top and front panels off to allow better airflow I get roughly a 5c drop in temps across the board. On the other hand, both panels cut down noise significantly. So I do have the option of removing them if I'm folding or otherwise putting a heavy load on the CPU. Gaming, the system temps stay reasonable, ~40-45c on the GPUs and no higher than mid 60s on the cpu (average cpu is much lower, in the 40's). Overall, I'm happy with it, but if I were to do it again I'd go with the Corsair Obsidion 750D. They're very similar cases, but the 750D would have been much simpler. When I started this build (i've been meaning to make this write-up for a while, sorry Dave), the 750D hadn't been released yet.
