this is my solution for temp. a 12x12 fan connect to internal fan connector placed on top unit.
eliminate cpu gap space and change paste =42C (10% cpu load my normal system running with proxmox) 50C 100% cpu full load stress test
add a 12x12 fan too=31C (10% cpu load) ,40C 100% cpu full load stress test
external fan give me a 10/11 grades decrease
my unit is v2 5105
i cant place internal 40x40 fan becouse i mount a sata ssd
external fan give me -10C on internal m2 disk too, from 68C to 58C
i thing it low the temp on intel eth chips too
next step is to design a 3d printed piece for to fix external fan to unit
read temp on my proxmox system: about 10% cpu load 24h/day, ambient temp is 29C
