Noctua NF-A12x25r - not really worth it for Noctua NH-D12L

My new core 19-12900K PC was experiencing occassional thermal throttling when running benchmarks and so I thought I would add a second fan (Noctua NF-A12x25r PWM) to the Noctua NH-D12-L. While It did not make any difference in the minimum temperature, it did bring down the max temperature during a benchmark from 100C to 96C. However, a few of the Performance cores still reported thermal throttling. I was hoping for a little bit better performance but turns out all the folks in reddit advocating against adding a second CPU cooler fan were right!

If you primary use pc on heavy rendering, why you choose so small case? Bigger case give you more cooling potential and you can use bigger CPU cooler like NHD15 for example. But even this cooler cannot degress lower temperature about more than 4-5 celsias. 12900 is just very hot itself, so you must lowering voltage and helping your cpu cooler little bit.

Too bad the retail version of the fan doesn't come with clips compatible with the NH-D15s. Have one of these in my rig and would love to mount one as a second fan for the cooler. Would complement the 140mm round frame fan that already comes with the NH-D15s(a second 140mm wouldn't fit due to ram clearance).

This Cooler is not designed for this CPU. - To get it to work with lower temps just limit power in Bios. I know this will give you lower results, but you will not get thermal throttling.
