What about the pc fan noise is that a consideration?

I just saw this topic, I kind of have a similar setup to what he is describing.

Fan noise isn't a problem as I have efficient cooling and large fans (larger the fans lower the resonating frequency). Also when playing back 4k surround footage my pc CPU idles at 1% when the fans haven't even turned on yet! (I did this by creating a custom fan curve, very simple process if you have the right motherboard).

I knew I was going to be using the pc as a source for an amplifier for a home theatre so I saved up a bit more and bought a motherboard with really great DAC and real Nicheon (I think that was the name - they are the gold ones) capacitors.

The PC has 4 stereo outputs so I could add another 2 speakers for 7.1 If I wanted.

When playing from all 7 channels it has a singal-noise ratio of ~120db which is really useful as a preamp.

Not generally. It is possible to build entirely silent PCs.

The Motherboards I recommended both have audiophile grade audio built in, and at a very reasonable price.

The low power Rizen/Athlon CPUs almost completely eliminate the need for big fans.

To be honest... home theatre duty is a very lazy task for a PC, these days.

Because My whole setup is in my room I use my gaming PC for it, I have a ryzen 2700x but I have a switch set up so if I flick it, it goes into what I call home theatre mode.

What, exactly, does this switch of yours do?

I have it so it activates a macro in my overclocking software to lower the fan rpms on my graphics card and CPU cooler whilst turning all boosts off and giving a slight underclock. Due to the cooler I have, I can choose to underclock it a bit more and the heat sinks just dissipate enough of the heat. 🙂
