This board has the 3950x listed on the compatibility matrix, so I took 
the punt. I am running a beta BIOS with the 1.0.0.4 AGESA but it's 
running in a stock production environment and has been stable. I don't 
overclock or game, it's predominantly a VM host.

It is fairly impressive and a significant update over the 1800x it 
replaced. Kernel compiles are pretty quick :)

No. I'm using a stock AMD Wraith Prism cooler in a 4U rack case.

It might reach higher boost clocks with better cooling, but under an 
all-core load I still see > 4.1GHz across all cores.
