What would that unused "West bridge" be? (The exposed BGA connection between the CPU power delivery and the rear I/O) On-board wireless? Second chipset?
Any logical design benefits to rotating the CPU and memory locations like that on the board? I'm guessing they only did so as a requirement to have PCB space available for that IPMI chip, but I feel AsRock's probably been one of the best at making good design decisions on constrained board space (see their MiniITX and MicroATX options for Intel Enthusiast series boards in the past, whereas most other manufacturers make ATX or EATX boards for those platforms.)
I mean, I guess it just looks odd to me. It probably doesn't have much of a negative effect (if anything) on compatibility with coolers or overall board quality.
Yes, it's so you can cool the damn thing properly. Cold air comes in the front and blows out the back (the 'rear' ports may be on the front or back in this arrangement) . DIMM slots need to be aligned in the direction of airflow as does the long side of the CPU heatsink, which in this case would likely also cover the power circuitry.
The fact that consumer mobos orient the DIMM slots the wrong way (90 deg to airflow) is a big reason why they're useless for high density applications. That is probably intentional.
historically blast from the front cooling like server boards use wouldn't work in consumer cases because they'd have drive bays in front of the mobo not fans. Instead the dimms are oriented to maximize convection of the hot air up to the top of the case where the ATX standard put the PSU with its exhaust fan. Dimms oriented server style would serve as baffles to trap the hot air below them in a standard consumer layout. Different airflow patterns need different board layouts.
High density servers are cooled by a bank of fans on the front of the chassis/blade blowing front to back because there's not enough room above the board for the heat to rise and be pulled out by the fan above IO panel or on the top of the case.
I use Supermicro 1U Chassis and ASRock WS boards. The DIMMs are set up perfectly as triple fans shaped like barrels blow through the DIMMs and make sure a plain old thick Copper Heat Sink is fine. Or one could use the Dynatron L3 Water Cooled Server which attaches the radiator to triple barrel fans. I’m still running H97 and C236 ASRocks and full load they run cool. This board will be my next build and for the sake of lower fan noise, the Dynatron L3. These barrel fans from Supermicro can top out at 22k rpm. Louder than my wife’s Shark Vacuum.
This is a great board. I’ll be using the E-2174G quad CPU though. Lower watts, lower temps.
DisplayPort output is clearly visible above HDMI. But it isn't mentioned in specs.
On the other hand, the D-Sub, which "will be needed mostly on a server version outfitted with the AST2500 IPMI chip": how can it work WITHOUT a BMC (absent on this one)?

What makes me laugh is the suggestion that there was/is some sort of thermal design put into ATX anything.DanNeely - Monday, July 16, 2018 - link
