CPU overheating

[mikhsabl15ac02ea]

Hello! I have a problem with my assembled computer.
The components are:

• Motherboard: MSI MPG Z890I EDGE TI WIFI;
• Cooling system: MSI MAG CORELIQUID E240;
• OS: Windows 11 Pro;
• CPU: Intel Core Ultra 7 265.

The CPU temperature in idle mode (in BIOS) reaches 104 °C, while the ambient temperature is only 40–50 °C. What could be the cause of this issue?

The CPU temperature in idle mode (in BIOS) reaches 104 °C

You're positive that it's Celsius and not the other one
as 104f is 40c and that would be correct

while the ambient temperature is only 40–50 °C.

40 to 50 °C Ambient, are you living in the middle of the Simpson Desert or something

Can you download HwInfo64

And supply a screenshot of the temp section

Is the fan/pump even spinning? Did you remove the protective film and apply thermal paste?
