So my second NR200 is on the way. I have noticed a lot of people on this thread went for the NR200P. Personally, for my at home gaming rig, a window is just not something I care about. My build goal is a stock 3600 (or new 5xxx series chip) and a solid 1440P GPU running smooth and quiet. My current rig has a 280mm AIO in it and short of the fact the FSP Dagger Pro 550 gets loud (more below) during gaming, my system noise does not change during gaming or idle, practically silent.
As for the PSU noise, I guess it is all subjective. My wife was in my office last night while I was gaming and I comment on how loud the PSU was and she started laughing at me. She can barely hear it. She thought it was funny because she can yell at me from the next room and I will say I cannot hear her and yet the PSU is barely above a whispered voice and I think it is loud
For this new build I am leaning air cooling. Looking at a C14S with a 120mm on the bottom of the C14S and the 140 on the case side rail. I like the fact that it is giving direct air flow to the motherboard. I am debating adding a second 140mm on the side for additional positive air flow. For this build I am gonna use a Corsair SF 600 though I am also looking at a Silverstone SX-700PT. With the second 140 intake I am considering turning the PSU around to see if that helps with noise as right now the right side of the case on the current build is facing me. (Wonder if that is why I hear the noise, if I turn it around it might help a lot.)
