High temperatures with the NZXT Z73 AIO and 5800X3D? The radiator keeps it cool, right?
High temperatures with the NZXT Z73 AIO and 5800X3D? The radiator keeps it cool, right?
Hello! I hope you don’t mind, but I’m looking for some advice here. I’m concerned my Z73 AIO cooler might be having problems and wonder if I should return it for repair. I’ve been using it for a year now. Before that, I had a Ryzen 3600 and the temperatures kept rising to 70°C or higher. After switching to the 5800X3D and adding a lot of Kryo liquid, the temps have stayed above 50°C and reached around 89°C during Flight Simulator. My room is air-conditioned in a tropical area with a temperature of about 24°C, and I’m using both a 3840x1600 and a 2560x1440 display. What’s troubling me is that the temperatures don’t drop even when I set the pump and fan curves to full speed. The radiator stays cool to the touch no matter what I adjust, and the pump spins at 2300 RPM max, though I feel some vibration in the tubes. There’s also an audible electrical noise when the pump runs at 45%, and during the re-paste I found a mark on the cold plate that didn’t come off with alcohol. I’m not sure if this impacts performance, but I’m feeling pretty confused. I’d really appreciate any thoughts! I’m trying to avoid buying a temporary cooler just in case it’s just normal behavior.
This processor operates hot but stays below 89°C during gaming. It jumped to 1.3V, which is unusual since the max is capped at 1.25V and still feels high. People often use Curve Optimiser to bring temps down further. The HW Monitor might be giving inaccurate readings; you could try HWinfo instead for better reliability. Check if the Skew setting in BIOS is enabled or disabled—it can significantly change reported temperatures even if the actual value is unchanged.
If the CPU runs hot, the radiator needs to reach 50-60°C or higher. It shouldn't be at room temperature. The two tubes must feel warm, with one slightly warmer than the other—not a big difference. Good water flow should be noticeable. What motherboard and BIOS version are you using?
Did you test the same cooler on the 3600? Your 3600x hit a peak of 70°C in Cinebench on Dark Rock 4 (not pro). It seems your AIO might need an RMA. Also, the airflow in your 3600x setup wasn’t very strong.
The B550 Aorus Elite v1 with F15D BIOS should not negatively impact the CPU performance. The HWinfo screenshot is helpful, but I’m still trying to interpret it. Regarding SenseMi, I’ll need to review it later.
At the beginning of the program, choose "Sensors only" to display temperatures, voltages, and other readings.
The voltage is still rising to 1.3V, which seems unusual. It could be related to a faulty LLC circuit or the motherboard’s automatic adjustments. Curve Optimiser adjusts the voltage curve so the CPU can run at higher clock speeds using lower power, essentially combining undervolting and overclocking. Some motherboards include this feature in their latest BIOS, while others don’t—you’ll need to configure it via the BIOS settings. You set it by choosing a negative offset up to 30, which for me works across all cores, lowering temperatures by about 15°C and keeping the CPU at around 4.45GHz instead of 90°C. Have you replaced your CPU only, or did you also reset the CMOS to restore default settings? There might have been lingering issues from previous auto-settings.
