Having difficulty picking a PSU and CPU cooler

[warm pancake]

Hello all. I have finally accomplished my dream of building a PC and ordered the first components today. However, as you see in the title, I'm finding it difficult to decide on a PSU and CPU fan. I tried using the calculators out there, but none of it honestly helped me and I'm scared of inaccuracy. The PSU is honestly the most confusing part for me, followed closely by the CPU fan. I know about the 212 EVO, it's popular and works. But it's too loud. I'm trying to keep a quiet build for my own personal preference and also so my family doesn't hear fans whirring all day and all night. But I don't want it too quiet that it sacrifices cooling.

That case hasn't been ordered yet and may change to an S340 or P400S, so whatever PSU/CPU fan I get would need to fit those of course. You could also leave recommendations for cases that are compatible with all of this. Thank you for helping me complete my very first PC, and Happy New Year!

I'd use a stand-up cpu cooler (just make sure the height will fit whatever case you chose) so you can blow the hot air out the back of the case (or the top, however you decide). Noctua makes great coolers, Cooler Master are good, too, and a little cheaper. Just make sure that whatever you buy will clear the RAM slots, too. Put your new case fans in the front of the case (save the top for the water-cooled cpu radiator...).
I'm curious: your board choice supports NVME m.2 (on the motherboard). You're building a nice kit, but have you considered a Samsung 960 Pro m.2 NVMe SSD as your C:\ boot drive, replacing the Samsung 850 Evo SATA SSD? Much, much faster than standard SATAIII-6GB/s.

Funnily enough I was about to make a separate post about the merits of going m.2 over traditional SSD, seeing as the price is similar. What is it about m.2 that's better? I want to understand the workings of it. And are the other brands of m.2, like WD, any good? Lastly I don't know how to decide between 2D and 3D. The SSD will be for my C:/ boot, documents and certain programs. As an aside, does my RAM seem okay to you? I'm having second thoughts, like maybe I should have ordered something higher since the board supports up to 4000mhz.

The m.2 is faster than a SATA3 SSD simply by virtue of being on a faster bus. Right now, Samsung is the King of SSDs, period. They are the best performers, although you pay the price for that.

I'm not a real big believer in overclocking (although I do it for fun, just to see...). In a production machine (the one you depend on for day-to-day work), you should avoid it. If you want to go faster, get a faster CPU, match the RAM to the motherboard, and get a GPU that matches the games AND MONITOR you use. As for overclocking memory, the gains are vanishingly small, and again, in my opinion, not worth it. Playing with CPU/RAM speeds can damage the motherboard, the CPU, the RAM, the GPU, etc, for what, in the end, amount to minimal gains.
