@famfo @lanodan i'm honestly half surprised it worked (the temps were nice too, and the noise was much lower despite no real fan control... and of course so was the power consumption since you no longer need like 250W worth of fans)
at least on power9 the socket kinda relies on the high pressure heatsink clamping mechanism to work correctly, and this arrangement was using normal thermal paste and everything, so the force/pressure was nowhere near as big
