all AIO pump always have noise, it depands your standard, perhaps your level of quiet is when you attach your ear to the pump and you still can not hear anything, then thats a different story, my pump's noise isnt that noticable at all, i think you are being particular to what I said, what I meant is there is minimum noise i can hear from my case , if wanting to pick a noise that I can hear, it would be the pump, AND I have to get my head very close to the case to hear it, are you telling me theres no noise at all from your case , no noise from you fan or cooler, even when you get your head very close to the case ? and you can only hear your coil whine ? I am very keen to hear your silent computer if you can record and put it up on youtube, if you still dont understand then theres nothing i can do, I am just trying to help. to add more information, i am also running 10900k, c-states auto, asus armory installed. what audio/video player are you using that you can hear coil whine when audio/video are played? what cpu cooler are you using, how many fans do you have in your case? and what rpm , dba are they? if i put a coke can on my table of course the bubble would be the loudest thing in my room as well, much louder than my pump if you still dont know how quiet my pump is, anyway why don't you record the coil whine and put it up on youtube ?
anyway I've heard coil whine from 1 of my old old graphics card many years ago, also seem youtubers video like Linus showing coil whines, i know what kind of noise that is, and i was very uncomfortable to hear it and if i can hear anything like coil whine, i would definitely notice it since i hate it and i am very senstive to it, was what i meant.
