I recently installed a Ryzen 7 5800X3D with Curve Optimizer set to -30 all-core. The system uses an Arctic Freezer 36 with a Carbice Ice Pad instead of thermal paste, a Gigabyte B550 AORUS ELITE V2 motherboard, an RTX 4060 Ti 16GB, and an NZXT H510 case with only two stock fans. One fan is mounted at the rear as exhaust and the other is on top as intake; there are currently no front intake fans.
While gaming in Black Desert Online, with the CPU using roughly 65W, temperatures average around 80°C with the side panel removed and peak near 83°C. With the panel closed, temperatures average around 85°C and continue rising slowly. Idle temperatures are about 60°C, while the BIOS shows roughly 50°C. The CPU fan also becomes fairly loud.
The cooler appears to be mounted tightly, the Ice Pad is centered, and the protective film was removed. I have already ordered two Arctic P14 fans for front intake. Should I install those and change the current fan layout, or is the Arctic Freezer 36 insufficient for this processor? Would replacing the Ice Pad with thermal paste make a meaningful difference? I would ideally like around 40°C at idle and 70°C while gaming, but I am not sure whether those targets are realistic for this case and CPU.

The Freezer 36 can be usable, especially with a -30 curve, but it is not an especially oversized cooler for a 5800X3D. Improve the case airflow first; the H510 with a restricted front panel is known to run warm. If temperatures and fan noise are still disappointing afterward, a dual-tower cooler such as a Thermalright Phantom Spirit, Peerless Assassin, or AK620 would provide more headroom.
Do not use 40°C idle and 70°C gaming as guaranteed targets. Ryzen processors can sit around 45–60°C at idle depending on background software, fan curves, room temperature, and boost behavior. Seeing around 80–85°C while gaming at roughly 65W is not automatically dangerous, particularly in a poorly ventilated case. BIOS temperatures around 50°C are also not unusual for this chip, since the CPU is not using the same power-management behavior as it does in Windows.
I would remove the Ice Pad and use the Arctic MX-6 paste that normally comes with the cooler. Thermal pads can work, but they require the correct pressure and mounting setup, and there is little reason to use one here. After repasting, check that the cooler is making even contact with the CPU. A bad or marginal interface could explain the relatively high idle temperature.
Those gaming temperatures are within the normal operating range, so this is not an overheating emergency. However, the 60°C idle temperature is higher than ideal, and the large improvement with the side panel removed strongly suggests an airflow problem. Install the two front fans as intake, then configure the rear and top fans as exhaust. The current top-intake/rear-exhaust arrangement is not giving the CPU cooler a clean path for fresh air.
That makes sense. I will try the front intakes and switch the top fan to exhaust before replacing the cooler.
I used the pad because a friend recommended it, but I am willing to test MX-6 if the new airflow setup does not bring the temperatures down.
