What Worked: Most everything. Define S was great to build in, the Phantek fans are whisper quiet, no major issues other than the few below
What Didn't Work: The Kraken. Banged my head against a wall for three days before figuring it out. It's default setting of adjusting pump RPM and fan speed was based on the liquid temperature of the cooler, NOT the temp of the CPU. Ended up with what looked like a richter scale of CPU spikes from the low 20's to the high 70's every few seconds. After finding the setting buried 3 deep in menus, I was able to turn it to the appropriate monitoring variable. Smooth sailing since.
The 950 pro. That thing takes some serious schmoozing to get to work right at full speed without CMS.
