power source fan keeps on after shut down

[Laurentius]

Hello.
I get this this issue on a desktop device: sometimes when I click Shutdown button (xfce's logout dialog), the system do shutdown, but some of the source power fans keep going. In that situation, the is no way to resume or restart the system without forcing the power off before (either holding start button for 5 second or plugging off the device). then you can start up and everything is normal.
This is happening since around several months.

I've tried 6.1x default kernel and liquorix kernel. Doesen't seem to be any difference.

A quick search suggests that your PSU is going sour and should be replaced.

Agreed. PSUs in many off the shelf builds are cheap junk. I've seen all kinds of bizarro stuff happen when they go wonky (sorry for the technical terminology).

[m_pav]

Speaking of hardware, It could be your PSU, but with ECS, it's just as likely to be the Motherboard. Both will have ageing capacitors, or E-Caps, which add a shock-absorber effect on the circuits to smooth the supply ripples in a circuit. Before I venture further, it may not be hardware at all as I have seen this phenomenon with devices at roughly the same age as yours when they were new.

The easiest way to tell if your PSU or MBD is on the brink is to get an eyeball on the subject. All E-Caps should have flat tops with an indent that have a point where each indent intersects or meets. The intersection points act as a valve whereby expanding gasses from inside the aluminum canister can escape and they should have NO bulge whatsoever. Even the slightest bulge means the capacitor has passed the end of its useful life, but they don't have to be bulging to be failing because by the time a 1000uF Electrolytic has started to bulge, it will be reading something like 120uF. When an E-Cap is delivering only 30% of its rated capacity, it'll be doing next to nothing anyway.

Now, let's turn to Software, and in particular, the Motherboard BIOS with the processor you're running.

A quick check on the ECS support page shows a BIOS update is available for your machine. Those processors had a few issues from having come from 1 of 3 manufacturing processes, so there were discrepancies in play from the very start. The ECS Support page for your MBD lists 2 BIOS packages, the first is the same as the one you have and a 2017 update that addresses the very thing I spoke of above.

Putting aside all the above, your machine may simply be shutting down the processor before it has time to issue the final command to bring the machine to a complete halt state. This too was an issue back then and I still see it from time to time on similarly aged hardware when a full shut-down is initiated. Windows users don't get to see it because their hybrid sleep shutdowns do not actually turn them off completely where the Linux shutdown actually means exactly what it says, shut the machine down to a complete a halt.

Having checked it's not a hardware issue, you could try a different kernel, for example, the latest AHS kernel or the same in Liquorix in MXPI to see if it makes a difference. There's more than a few folk here that have switched to Liquorix kernels and they've eliminated issues for them. Just keep in mind your power consumption will go up fractionally because the kernel clock "tick" speed goes from 250hz which is ideal for servers to 1000hz which is where AV creators and gamers are at. Liquorix (and Xanmod) kernels make a system feel snappier, but at the expense of processor throughput, so things like Disk IO will take a bit of a hit. You probably won't even notice it if I didn't tell you, but it's one of those good to know things.

Your machine will respond favorably to being upgraded to AHS too, and with with no need to reinstall. Just enable the AHS repos and upgrade everything.
