Same thing, it will just isolate components from each other so that only the parts under load will heat up, but then you'll get the performance of 1x 360 instead of 3x 360 rads. So really you should never separate your components into separate loops.

The difference is that if you run something that is only CPU intensive or only GPU intensive you get effectively half the cooling capacity than you otherwise would. So no, not really a good thing.

It depends because the human eye isn't analogue, so an image that changes slightly every frame (eg. a video on a screen) is completely different from a white square flashlight on a black background, or the flash of a bulb. https://www.researchgate.net/post/Whats_the_Human_eye_Refresh_Rate_maximum_we_can_handle_more_closer_to_the_Max_Value https://en.wikipedia.org/wiki/Flicker_fusion_threshold There's a bunch of papers on it you can find. 2-3khz seems to be the typical limit for a general human being.

Take an aux cable (3.5mm to 3.5mm) that goes from your switch to the line in (blue) port on the PC. In your windows sound control panel click "listen to this device" in the line-in jack properties.

They're optical, there is no bandwidth decrease with more length. That's why they're so expensive.

Less than $200 for a 15m optical one, in the link above.

1920x1200 at 60 Hz is not anywhere near 4k 120Hz bandwidth he wants. Maybe try looking for optical HDMI cables? https://www.amazon.com/dp/B081SHJJ3C?th=1

Usually only 9.1 setups have ceiling mounted or upwards-firing speakers. You typically want the surround sound coming from actually around you, not just above you.

Drivers are what makes the hardware interface properly with the software or OS, so yes if you want that to work you need the drivers.

No, you should reinstall all your programs. Programs can only be moved if you clone the entire OS, which is a bad thing to do because it often screws up windows.

Copy paste in file explorer?

If it's on an exhaust all it's doing is removing dust from your room, not the PC.

Reinstalling windows might fix it and is free, so why not? Or if you have money and wanted a better SSD anyways I'd suggest clean installing on a brand new SSD so you only have to do it once.

Windows can read FAT32 just fine, your USB drive is screwed up. Try windows administrative tools disk management and see if you can reformat it.

Reinstalling windows helps a lot if it hasn't been done in a few years.
