I also have 16GB, mine are for graphics. The fan noise is okay as long as the graphics card fan doesn't need to kick in too much.
Now if only I hadn't spent all my money building the PC so I could buy the games it can run.

J/k, it was only $1.1K.
It is having issues though, it's been either randomly losing power or losing input to the monitor (some days one, some days the other, some days both--rather annoying). I'm hoping I fixed at least one of the problems last night when I reseated the memory cards and some connectors, I also found that I only had one of the ATX 4-pin connectors for the 8-pin power plugged in this whole time. The other one had a cover on it so I assumed that it wasn't supposed to be used, but the manual clearly states the motherboard uses 8-pin power, so we'll see if having both plugged in helps.
