Welcome to SPCR!
Very clean build.
Did you try it without the foam? -I find foam's acoustic dampening qualities in PC builds are mostly a placebo.
Thank you, though I'm not exactly new here, just not a regular poster;-)
I did not do any A/B testing without the foam. I have no doubt that covering metal surfaces would make a measurable difference by reducing internal reflections. Whether or not it would be audible or not a meter away from the box is another question, and I'd guess the answer is probably not much if at all, especially at idle. I do have a sound meter, but the ambient noises like the furnace and monitors in my office tend to be what I hear. If I put a game on, the GPU fan becomes obvious, though still pretty quiet in my opinion.
Nice clean build, enjoy =)
Btw how is the Gigabyte fan control?
How fast is the TY147A spinning at idle and the Case fans?
Right now, the CPU fan is reading 610 RPM. It kicks up to nearly 1300 RPM when I run stress testing. I have selected the Quiet setting in BIOS for now. To be honest, I really haven't experimented much with the CPU fan settings and will look into them more. I know the Gigabyte windows utility allows you to calibrate multiple manual fan speed points vs. CPU temperature, so I'm guessing I could set it a bit lower at idle to take advantage of the low minimum RPM on the CPU fan.
As for the case fans, I don't have them on the motherboard controller. I have the front and rear fans hooked up to separate built-in front slider controls on the Nanoxia DS5. I keep them at the lowest setting unless I am running stress testing. I'm not sure what the minimum voltage is for those sliders or the resulting fan RPM, sorry. In general, what I hear sitting at my desk are the two monitors and slight exhaust fan noise.
It's definitely not a completely silent system, but is quieter than my last system which was reasonably quiet as well.
