Sounds inaudible for others are annoying to me. For example my MSI 980 Ti I sold few weeks ago was whining like crazy for me, while no one from my family was able to hear it and guy who bought this card from me also said that he is not hearing any coil whine, like completely none. Not to mention what happened when I got 980 Ti Hybrid with its pump noise... This is just stupid, there is no advantage of having such sensitive hearing, it is not only useless but also annoying as fcuk.
But after long fight with stupid build of my old case, I was able to get fan controller out, it is working on 5V-OFF-12V, so problem is solved. 7V introduces a lot of rattling so I wouldn't use it anyway. I will mount it to one of those 5.25 covers from Define R5. I have two fans in front, one on the bottom near PSU and one on side panel, so it should be enough intake even at 5V. I plan to get RX480 and then get Vega, so I will just make fans of GPU not to exceed case fans noise levels and I will get my desired nearly silent gaming. And with Vega we will see how hot will it be and how cooling solutions evolve, I am really interested in Raijintek passive water cooling. Sound like dream solution, I wonder what performance it can provide.
I hear ya, it's the same here on OCN, most people are deaf and noise doesn't bother them.
But the AIO passive WC is more of a dream than a working solution, the pump/flow action provided is likely to be so small making an effective cooler out of it is not going to be any more effective than using a simply aluminum air cooler which have been around for decades and work well.
I do not know why fan makers didn't use magnetic bearings yet really, it's the most obvious choice for a bearing that makes no noise and doesn't need maintenance. I don't like ball bearings as they are the loudest, most expensive to make, easy to break if not done in quality, ... sure they are better than plastic sleeve bearings but if one uses a quality sleeve like bearings they are near silent and last forever. And when it comes to extreme loads/forces ball bearings are the last to go with as they are easy to overload and fail. Don't even think about dust and particles inside the ball bearings housing, noise and fail. So I don't get the PC market's obsession with ball bearings. I guess it's because they tend to make them in higher quality than they bother with sleeve bearings quality. Fans being electro magnetic motors, magnetic bearings to me is a no brainer especially since fans have light load/forces/torque.
