i wasn't much interested because x86/x64 thermals are a horrible match for an SBC form factor, buuuut, Explaining Computers on YT just did a video where he used the (huge) heatsink case and fan, and while it quickly throttled with the supplied thermal pad, he added a (third party) copper shim and paste, and then could run long benchmarks without throttling. interesting.
