CPU Overheat Help
CPU Overheat Help
My computer shut down abruptly to a black screen during a light game session. After turning it off, I restarted it shortly and encountered CPU fan and overheating warnings in the BIOS before the system even loaded. Repeated attempts to boot through Windows failed without crashing. Recently, I purchased thermal paste, cleaned the PC thoroughly with an electric duster, and repositioned the CPU and cooler. When I powered it back on, the monitor still wouldn’t display. A whirring, chunky noise appeared when I turned it on again, indicating the CPU cooler was disconnected from the power supply. After a few restarts, the BIOS eventually appeared but crashed immediately afterward. My suspicion is that both the CPU and cooler/fan require replacement. It seems the cooler may have been faulty without prior warnings, continuously stressing the CPU. If you have suggestions or resources for affordable replacement parts, I’d appreciate it!

It seems the AIO has likely failed or is nearing failure. The exact age isn’t clear, but it probably isn’t covered under warranty anymore. Without proper cooling, your PC might not start or shut down promptly after booting to prevent damage. There’s a chance the remaining parts are still functional, but you’ll need a replacement cooler.
You almost certainly need a replacement cooler. The warning about the fan failure is meant to alert you immediately to power down the system and inspect the part for harm. If the fans aren’t running in your AIO, it’s likely the pump overheated too, since both coolant and radiator are handling the same fluid. This often leads to bearing damage, and water flow will stop completely—something that might go unnoticed during light gaming or background tasks but can become serious eventually.
Your current AIO is probably past its warranty window. Generally, you should rely on the warranty for about two to three years of reliable use on a high-quality unit. Eventually, the coolant will be depleted enough that air circulation won’t work, rendering the pump useless. I’d recommend swapping it out for a solid tower cooler right away. If you can’t find one, consider getting a new AIO, though prices have risen significantly—many affordable options still exist.
