The FAN brand can make all the difference IMO, I tried some in my quest for a dead silent PC.
An airflow friendly case can account for the most, regarding temps, but they will let the fan noise come out as well.
2x 140 Intake NF-A14 Noctua Chromax
1x 120 Exhaust NF-A12x15 Noctua Chromax
2x 120 Ryujin NF-F12 Noctua iPPC (@800rpm)
1x VRM Fan Ryujin (@400rpm as this fan can get loud easily)
3x GPU @900-1300rpm depending of the game
1x PSU Strix 750 but mostly off unless I start rendering hard
Corsair LL or ML need to be at very low speeds or they will be noisy, ML can really push some serious air and the AF too but Noctuas can go higher on rpm to compensate, but no RGB...
Cooler Master was great for the first year, then started rattling. Phanteks.. sorry but no. Be quiet is amazing too but they don't push a lot of air. NZXT, Zalman and Thermaltake on the average.
