That looks like a combination of improperly mounting the heatsink and noctuna being wrong in their recommendation to offset it. I’d imagine for gaming cooling one side more makes sense but my completely uneducated guess is that GMP is working a different part of the CPU than gaming does.

They had failures with standard mounting and offset mounting.

Also, take a look at a delidded 9950; the two cpu chiplets are to one side, the i/o chiplet is in the middle, and the other side is a handful of passives. Offsetting the heatsink moves the center of the heatsink 7mm towards the chiplets (the socket is 40mm x 40mm), but there's still plenty of heatsink over the top of the i/o chiplet.

This is what Zen5 looks like under the IHS: https://i.imgur.com/j85YUzX.jpeg

Everything is offset towards one side and the two CPU core clusters are way towards the edge, offset cooling makes sense regardless of usage.

I'd assume both GMP and any CPU intensive game just prefer the performance cores.

AMDs desktop chips don't have distinct P and E cores, they're all P cores. AMD do have an E core design but it's currently only used in mobile and server parts.

Gotcha. Apparently Intel's marketing's gotten to me. I haven't really been keeping up with this stuff, so whenever I read about P & E cores in the past, I think I just assumed that was a thing both Intel & AMD were doing, without considering the source material too closely.

AMD has definitely been moving in that direction, and arguably doing a better job of it than Intel. But for now, AMD's desktop parts are still built with the same CPU core chiplets as their server parts, and none of the server parts are using heterogenous cores yet (from AMD or Intel). At some point AMD could theoretically build a desktop processor from one Zen chiplet and one Zen-c chiplet, but there hasn't been a good reason to do that yet.
