YouTuber Der8auer has proven off a couple of recent AMD AM5-based B665 workstation motherboards that includes a 90-degree socket orientation, designed to fortify airflow and fortify compatibility with server-based CPU coolers and chassis. The 2 new forums are the Asus Professional WS B665-ACE and Asrock Rack B665 D4U1L.
We do not know the rest about this new B665 socket, or a lot about those new forums on the whole. However Der8auer says those are value-oriented workstation motherboards, with a minimum quantity of options. On the very least we all know they’ll give a boost to AMD’s 65W Ryzen 7000 collection CPUs.
In response to the pictures of each motherboards, they look like cut-down variations of B650 chipset motherboards. The rear I/O has been considerably reduce to avoid wasting price, and a VGA port has been added for server functions. Each forums even have reduce PCIe connectivity from Gen 5 to Gen 4, alternatively, in step with Der8auer, this seems to be a board-specific limitation, once more to scale back price, and is not a limitation of the chipset. The Asus board is an ATX answer, whilst the ASRock board is a micro-ATX answer.
Probably the most distinctive facet of each forums is the 90-degree orientation of the AM5 socket, which is best commonplace on server platforms and workstation platforms such because the Xeon W3400 collection or Threadripper Professional.
The 90-degree orientation is ordinary for person platforms, however it is extremely opportunistic for server cooling answers and chassis, the place a majority of these forums will most probably are living. The 90-degree rotation approach elongated server-class heatsinks can be utilized, that includes fins that prolonged outwards via a couple of extra mm in comparison to usual coolers. This permits the air to stick within the heatsink fins for longer, and extract extra warmth from the fin stack, lowering temperatures via two or 3 Celsius.
Every other cooling advantage of the 90-degree rotation is the repositioning of the DDR5 DIMM slots from the facet to the highest of the board. This opens up airflow from the chassis’ consumption towards the CPU heatsink, and likewise cools the DDR5 reminiscence higher for the reason that air travels during the gaps within the modules vertically as a substitute of passing over them horizontally.
Der8auer demonstrated this capacity, with the Asus B665 board housed inside of a Hetzner AX52 server rackmount chassis. The 90-degree orientation allowed an elongated server heatsink for use, and the rear exhaust fan was once in a position to drag air immediately into the heatsink fins completely. If you’re unfamiliar with rackmount servers, the chassis lovers are designed to chill each the chassis and the heatsink itself. Negating the will for devoted chassis lovers and CPU cooling lovers.
This sort of cooling metrology might be nice for techniques that make the most of those consumer-based workstation motherboards. Motherboard producers were generating workstation motherboards for Intel and AMD’s person platforms for years as another strategy to dearer and devoted server {hardware}. That is nice for small workstations or server packages that do not essentially require all of the options or horsepower of a Xeon or AMD EPYC processor.
