Thanks for the explanation.
I thought I had to connect the case fans to the mobo for variable fan speeds. It makes perfectly good sense to just run them hard wired.
The CPU heatsink it supposed to be so efficient that, under normal conditions, it shouldn’t even need to run its fan. I like the idea of the CPU fan being a backup to the normal heat elimination of the case.
I did do research, bought a plug and play setup, and it didn’t work. Probably because I bought used components to keep the cost low.
Still running used components, but they are all gaming pc parts now. Not a mix of Dell office machine and gaming aftermarkets that are supposed to be compatible.
I realize this is a moped forum. It is my only forum/social media (I only look a some memes on FB). And the people here communicate better than the PC forums my google searches have landed me on.
Computer forums have answers in threads that range from show-offs giving complex answers in binary; which I can’t understand. To someone writing a 3 page book about how they “thought about using this thing” or “an article in complicated pc builders magazine says...” and it never gives any actual information. Like those yoottube vids were someone talks and fingerbangs an item for 20 mins and wraps up with: “I haven’t actually run this yet, but I will post another vid when I do.” And you look to see the video was posted 5 years ago. 😒
And, my kid having a good PC is going to yeild moped results. We are also getting a 3D printer soon and parts for molding and casting will follow. I intend to teach him by employing him. Like, I will draw the basic thing I want and then let him engineer and manufacture it.
