I will say that that cooler is undersized for the CPU but I don't think you have better options here.

Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues.

I feel the need to discuss the SS02 bearing systems because in something this small, it truly is amazing. Registered office: Klarna UK Limited, 7th Floor, 33 Cavendish Square, London, W1G 0PW, United Kingdom.

The NH-L12S is a low-profile quiet cooler designed for use in Small Form Factor cases and HTPC environments. The bottom line is that Core 2 is the name of Intel’s latest line of CPUs, based on a new micro-architecture, designed for speed and efficiency. Notice the extra thickness of the aluminum block that sandwiches the heatpies and the copper base, on which resides the fixing securing plate. On the other hand, the pretty compact dimensions make the cooler fit pretty well on the motherboard and doesn’t interfere with the other components. The specifications for the NH-L9a-AM4 is available on Noctua’s product page, however we have reproduced them below for your convenience.

g. NH-D15 or NH-U14S TR4-SP3) may overhang the RAM slots and that this can cause compatibility issues if RAM modules taller than 32mm are used. While it provides first-rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 95W TDP (Thermal Design Power).

This exact frame in the benchmark has some CPU spikes but overall the temps shouldn’t go higher than +/- 5-7 degrees from what you see here. For example, if a cooler uses a 140mm fan that overhangs the RAM and 46mm tall RAM modules are used, the max.Keep in mind too that you'll rarely 100% a 5800x3D while gaming, so cinebench all core testing is really more of a validation than a metric to operate off of.
