Very happy overall with my build (https://uk.pcpartpicker.com/b/9nr6Mp) but I have a niggling problem with the noise coming from the Wraith Prism cooler when the machine is idle. It's just a kind of electrical "buzz" accompanied by a faint whirring of the fans. I don't know if it's genuinely "noisy" or if I've just become obsessed with focussing on it when the room is otherwise deathly quiet. My Zotac RTX 2070 only becomes noisy when the fans kick in full during intense gameplay, and even then it's just a blowing noise, not an electrical buzz noise.
Would a Dark Rock 4 or equivalent make a noticeable difference to the sound profile of my setup? As anyone replaced a stock Wraith Prism with something else that's greatly reduced the idle fan noise? Am I just imagining the "noise" in the first place?!
