I have two nuc8i7beh.
These two have different types of coolers.
Test results show performance differences.
I have tested it more than 10 times.
CINEBENCH_R15 has about 10 ~ 15% performance difference.
- left cooler
- right cooler
There is also a difference in the geek bench scores.
At first I thought it was a yield problem.
Cooler Crossing Result I firmly confirmed that the cooler is the problem.
No, the "coolers" (vapor chambers and heat pipes) are identical. What is different (or at least potentially different) are:
- The manufacturer of the blower used with this cooler and differences in their translation of Duty Cycle into blower speed.
- The BIOS configuration for blower speed control (response to temperatures).
- The BIOS and Windows configurations for processor performance.
- The effectiveness of the TIM applied between the processor's heat spreader and the heat pipes.
