Having the NH-D15 in Meshify C would result to a misplaced second fan if the RAM is too high, which is too often the case if you buy "good" RAM. In the end, the difference of the cooling performance is so little, that using NH-D15S is perfect. Just use the middle fan. The NH-D15 has an incredible reputation, its performance is optimal (equivalent air coolers, even if cheaper, are only ever "as good" within margins of statistical significance), it has a reputable and massive warranty (and Noctua's RMA procedures, while weird result in very little downtime for the user if their shit breaks), and Noctua's Step 3: Install the Noctua NH-D15: To install the Noctua NH-D15, begin cleaning your CPU’s surface and putting thermal paste on it.

Though igorsLab says the 14th gens are flat. Keep in mind that everything is manufactured with a certain margin of precision. Applies to the Noctua and CPU headspreader. RAM clearance between D15 and D15S is only 1 MM, 64 vs 65. Mounting the fan on the rear can cause turbulance, as there needs to be 5MM of space in between the fan intake side and the heatsink. And the D15 doesn't come with 4 extra thicc anti-vibration pads to solve that, unlike the U14S.
