CPU Overheat and Crashes
CPU Overheat and Crashes
Hello, upon booting your system you experience slow performance, frequent black screen crashes, and high idle/launch temperatures around 80°C. Even after replacing the CPU, installing new coolers, and thoroughly cleaning and reassembling everything, the issues persist. I’ve also double-checked the CPU and board connections, and verified all PSU connections are secure. For reference: https://pcpartpicker.com/list/P3Kjyg
The previous cooling solution might not be ideal, but it should function with a 3770K. If the cooler is correctly mounted, the issue could lie elsewhere—such as a faulty sensor on the motherboard or CPU leading to shutdowns or overheating problems.
I used to own a Corsair H80 before making the switch. I’ve replaced the CPU, applied thermal paste, and followed several installation guides. It seems I’m doing it correctly this time.
You verified linking the radiator fan and water pump wires to correct locations on the motherboard and set it up so the pump appears as a pump, not merely a CPU fan.
It seems like the issue likely stems from a faulty sensor or another problem within the CPU. Given its age, it’s possible it’s beyond repair.
It seems the problem with overheating or crashes was present before your upgrade to the new CPU and AIO. You replaced both components but it hasn’t improved. Possible reasons include incorrect installation of the AIO, a faulty sensor, or a failed pump header on the MoBo. If you have one, consider testing with an alternative air cooler or verifying the pump’s functionality.
Consult your motherboard manual for a diagram showing all connectors and headers, such as "pump" and "CPU fan." Verify that both the fan and pump cable are properly attached to their respective connectors. When uncertain, refer to the manuals of your motherboard and AIO, as they should provide similar details. Finally, check the BIOS settings to determine if you can switch between DC and PWM modes or control a fan versus a pump. All instructions should be clearly outlined in the documentation.
