Unfortunately, you cannot compare the results from the review with your own for a simple reason - your results were taken on different equipment and in different conditions, with another laptop copy, whose coolers may indeed be louder than others - after all, Lenovo does not officially indicate the series noise level limit, right? No formalization of test conditions - no reliable results. The results of rare copies of laptop this model provide no indication of what the next buyer will have in their hands...
Just like with HDD noise, you never know how noisy the next instance will be, because... HDD manufacturers indicate only _typical_ noise, not maximum. Do you understand the difference?
And laptop manufacturers have never even indicated typical noise under 100% load on the CPU/GPU, and even more so when only the CPU is loaded or 10-30-50-75% load of cores. They don't think it's important.
Where buyers pay very much attention to this (for example, in projector's market), the noise level is indicated. But even there, projector manufacturers lay out legal straws for themselves - they do not indicate either typical or maximum noise. Just noise. And what is it? Spherical horse in a vacuum...
