Problem with high processor temperature.
Problem with high processor temperature.
Hello, I recently assembled my new PC and have encountered difficulties with it shutting down unexpectedly. Based on your description, it seems the CPU is overheating, as indicated by the BIOS reaching 90°C instantly followed by a spike to 99°C. It starts up normally but fails to boot, sometimes turning on briefly before powering off quickly. After a short wait, it usually restarts itself. During Windows installation, it would power down entirely without restarting, suggesting a possible issue beyond just the BIOS. The CPU cooler you're using is a Corsair AIO model, and you've noted pressure on the CPU from the thermal paste. Despite your efforts to ensure proper contact, the system isn't cooling effectively. This appears to be a recurring problem with the CPU temperature management. Full PC specifications are available here: https://pcpartpicker.com/list/HqmMcx
Some AIO pumps include a plastic label on the base, have you verified its removal? At such elevated temperatures, do the hoses appear warm when you inspect them? If not, it suggests the water isn’t flowing properly and the pump may be inactive or malfunctioning. The AIO radiator should be positioned above the pump, not below, to ensure small air pockets remain in the radiator rather than inside the pump itself.
If you mean the plastic layer over the thermal paste, then yes I took it off. After powering up the PC and letting it start, the radiator tubes aren't warm to the touch. The AIO is installed properly with the radiator on top, the pump at the bottom, and it's connected to the CPU fan slot and fan controller. There isn't a separate AIO_pump fan port on the motherboard.
If the CPU temperature is between 90-96°C and the hoses feel cold, the fan isn't running and the coolant isn't flowing. When the temperature is high with active circulation, the hoses should feel warm, particularly the one moving fluid from the pump to the radiator. At this stage, consider checking other fan connectors.
You're implying the images are old or the device is flipped. That's not true—they're clearly correct. Your reaction seems frustrated but unfounded.
You have your radiator upside down for a specific reason, though the exact cause isn't clear. It might be for maintenance, storage, or to access it more easily. Let me know if you need further details!
Do you have an alternative cooler? You can test different options by swapping it out and checking the temperatures. If the new setup improves things, it might be time to return your AIO. This method is actually a better way to install the radiator than the "downside up" approach.
I attempted to use a slot next to the CPU_Fan named CPU_Opt, which seems to perform the same function. I verified that the pipes connected to the fans are indeed spinning, suggesting the pump is working. The CPU temperature is rising to around 100°C, while the nearby tubes are hot but not excessively so. This leads me to think the device might still be improperly installed.
I’m thinking about getting a Noctua air cooler and was hoping to repair it if needed. Maybe I can install it while keeping the radiator in the case for testing.
