I finally finished my benchmarks and modded the MacBook with added thermal pads between the heatsink and the bottom aluminum. In conclusion, the MacBook runs up to 15C cooler and perform between 5-10% faster on long and demanding workloads.

Temp idle Mod:
Cinebench R15
Run1 stock:
Run1 Mod:
Look at the temperature difference when compared to stock! As a result, higher peak performance.
Run2 stock:
Chip got very hot and fan was not spinning. Score dropped significantly (to 615).
Run 2 Mod:
Temperature still below 80C and score is higher than "Run1 stock".
Run6 stock:
Fan finally kicked in (since run4) and score went slightly up. Temps still reach 98C
Run6 Mod:
On the 6th run, performance is still on par with "Run1 stock" with temps below 90C.
