I finally benched seriously Hasfail platform, this time using EK-SF3D Inflection Point EVO & EK-SF3D Triple Point EVO
1. Mounting system works great, it's easy and fast (but you need to get used to it after using old brackets).
2. CPU and MEM pots don't freeze motherboard as much as much bigger pots, but still handle 4770K Hasfail very well in 2D benchmarks.
3. During OC I was using HEAT system, not sure if it helped, but I could bench my Hasfail longer with full MHz (6.5+ SPI32M) before it gets "tired" and loses stability at full MHz, normally it happens after 30-40 minutes, and I benched 2+ hours without any stability loss.
4. Isolation on board for CPU pot is a piece of cake
