For me, the motherboard looks much more interesting without the heat sinks and shield.
These are the block diagrams for the motherboard when using both 28 and 40-lane CPUs. The switching of CPU and PCH lanes is quite intense, but it allows for many different configurations.
The CPU VRM on the X99-Deluxe II is a true 8-phase controlled by a rebadged 8-phase PWM controller. I assume it's the IR/Infineon IR3580 fully digital high-performance PWM. Each of the phases uses an Infineon/IR IR3556 PowIRstage capable of 50A output, a high current inductor with heat-fins, and 10K rated black capacitors.
Each memory VRM's main DDR4 voltage rail is controlled by a rebadged ASP1250 PWM and uses two Texas Instruments CSD97374Q4M NexFETs for each set of four DIMMs. A GSTek POL is used for VPP memory VRM power.
One of the main selling points of the X99-Deluxe II is the additional ThunderBolt 3 card. This card uses Intel's Alpine Ridge DSL6540 controller, a Texas Instruments TPS65982 type-C power delivery, and controller, as well as a few voltage regulators to produce the proper power delivery required.
The fan extension card uses a nuvoTon W83L603G and an NCT7802 to produce the fan control mechanisms.
The X99-Deluxe II also has a plethora of ASMedia ASM1480 quick switches used to switch around CPU and PCH bandwidth to provide all of the features.
