The airflow in your Cosmos 700 seems to be directing more air toward the rear while pushing air forward, which can affect cooling performance. The high temperatures you're experiencing—especially when the CPU hits over 60°C and spikes to 90°C during intensive tasks like Apex—are concerning. This is unusual for a simple game and may indicate thermal throttling or insufficient cooling. Your room temperature of 20°C in Bogotá means the environment isn't very hot, so the issue likely lies with your case's design or airflow management. Consider checking fan placement, adding more cooling solutions, or ensuring proper ventilation.
Both hoses feel warm, the radiator seems to heat up, the thermal paste appears aged, you're possibly doing some overclocking, and the motherboard BIOS is up to date.
@191x7 offers useful ideas to review already. My initial thought based on temperature/behavior would be to examine the mount. Monitoring pipe and radiator temperatures during operation can indicate proper contact. If readings reach 80s or 90s, you should notice a warmer pipe from CPU to radiator compared to a cooler one from radiator back to CPU. Also, verify that the plastic protective cover was removed from the cold plate—this might be hard to confirm if thermal paste has spread over the surface.
Is your CPU cooler operating at maximum capacity during intense gaming sessions? Have you modified the fan settings in BIOS? Which motherboard are you running? Your Arctic II 240 reaches around 1800 RPM when the processor overheats.
