Power issues on new Fedora 40 system

LDLC contacted me and suggested updating BIOS as there was some updates regarding the series of my CPU and to disable Windows fast startup, which I did.

We’ll see from here.

Use can use sensors to monitor fan and pump speeds.

Did you run ‘sudo sensors-detect’ first to setup?

$ sudo sensors-detect

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): 
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      Yes

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): 
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): 
Using driver `i2c-piix4' for device 0000:00:14.0: AMD KERNCZ SMBus
Module i2c-dev loaded successfully.

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
https://hwmon.wiki.kernel.org/device_support_status for driver status.

Accepted all default answers. sensors gives the same result.

If those screws were not initially tightened evenly the thermal paste on the processor would not be evenly distributed. It may not even be fully in contact across the processor and certainly would not be of even thickness.

Tightening the last screw would have evened out the contact and eliminated the uneven heat transfer.

Those screws must be evenly tightened and the cooler in full contact with the processor across the entire surface or there will be uneven heat transfer and hot spots.

Unfortunately I still had the problem today.

First picture is when I had the problem and the other is after reboot.


Here is the BIOS too

I got back my computer, they said the cause was a loose cable of the liquid cooler, I didn’t see anything personnally.

We’ll see if it works fine now.
