Got all the parts and built the machine. Jeez! That heat sink is huge! Thank goodness for modular power supply cables. Otherwise I wouldn't be able to make the CPU power connection as the sockets were under the heat sink. With modular cables, though, I plugged them in before installing the mobo in the case and routed them through the pass through above the mobo and behind it. The case came with two 120 mm fans mounted: front and rear. I removed the front fan to see how the computer would perform without it. I don't think I'll reinstall it. These fans, though quiet as they are, are three pin ones. Do four pin PWM fans offer any advantages over these? I ended up removing the 3.5 inch HDD bay to make extra room for the cables coming out of the power supply. I won't be using spinning rust in this build and this case has a nifty behind-the-mobo SSD mounting bracket. Did a fresh Windows 10 install, loaded the drivers, updated BIOS and left all the OS and BIOS setting (except for changing the power plan to "Performance") at default. Ran Prime95 torture test for about 18 hours without any errors. Ryzen Master was showing CPU temperature between 65 - 75 Celsius. But what was most interesting was that even with all the cores pegged at 100% and almost all of the RAM being used the system was barely audible. And it was only slightly louder than when running at idle. In both cases it's whisper quiet and barely distinguishable from ambient noise. I can still hear it if I focus on it but otherwise It just melts into the background. I like it a lot! One thing I noticed, though, is that the RAM runs at DDR4-2400 but it's DDR4-3200. I'm not sure if the systems needs any tweaking but I'll see if I can make RAM run at DDR4-3200 and if it has any impact on speed/stability/noise. But that's something for another post.
Thank you DrCR and everybody else for your contributions in making my build a success!
