Noctua could work, but it would definitely get you there if the CPU remains steady. EVO seems capable of managing it. The D15 might even allow it to go further.
If you're serious about overclocking and prefer a quiet system, a 140mm CPU fan paired with a large heatsink works well. My setup performs similarly to the D15 and is much quieter than a 212. However, the outcome hinges on your CPU's capabilities. It could struggle to reach 4.5GHz or might require excessive voltage. It's essentially a risk. If you're willing to invest in a premium air cooler, it's worth considering. They usually offer superior mounting solutions (such as Noctuas systems), are extremely quiet, and perform comparably to quality AIO watercoolers. I recommend sticking with what you have or the D15 if you can afford it and it fits your build (my and the D15 models have no RAM space concerns).
The 212 looks good, another solid option is the Cryorig H7. Either one should work.
