That’s it. The baseplate has some thermal pads for the FETs & inductors, alongside some fins near the DisplayPort & I/O, but is otherwise plain. The cooler is a large, aluminum block with standard 90-degree fin pitch and standard fin density, using flat-top fins to force air through the cooler block more efficiently. This exhausts out the back of the case, as expected. Conduction is handled by a copper protrusion in the copper baseplate, which covers both the GPU & HBM2 (two stacks). This is a vapor chamber cooler.

As for measurements, we took a pair of calipers to get some rough measurements. These may be off by 0.25-0.5mm. Here’s what we came up with:

• 30mm x 30mm total size of interposer + GPU (does not include substrate)
  
• 20.25mm x ~26mm GPU die size
  
• 10mm x ~12mm HBM2 size (x2)
  
• ~4mm package height (this is the one that’s least accurate, but gives a pretty good ballpark)
  
• 64mm x 64mm mounting hole spacing (square, center-to-center)
  
• PCB ~1mm
  

Our VRM & component-level analysis will come next, conducted by GN resident overclocker Buildzoid. Power, thermals, and noise will be around the same time for publication.
