Cpu overheating
Cpu overheating
Your motherboard recently failed, and you replaced it. You had a R7 5800X running well at around 65-70°C even under heavy load. After the swap, the CPU stays idle in BIOS at about 57°C. When you start anything, it instantly jumps to the 70s, and bench tests hit 90°C in seconds. It looks like the cooler isn’t working properly, but after checking it’s fine—no clear cause yet.
No, I didn't see that mentioned. You haven't specified whether the CPU cooler was re-pasted.
Sure, I got it. The auto voltage for the CPU is 1.47 volts, which seems quite high. Could you confirm if that’s accurate or if there’s a misunderstanding?
ASUS motherboard problems? Many manufacturers set default voltages too high for AM5 boards, risking CPU damage. Gamers Nexus covered the issue thoroughly. Be sure to refresh your BIOS! Note: I realized the user doesn’t own an AM5 board.
Review configurations such as Power Limits; they are usually enabled without restrictions, allowing the CPU to increase performance significantly over time.
Check the typical voltage and clock settings for this CPU. Look into methods to disable boost mode consistently.
