I have an i5-14400F, a 9060 XT, and a PRO B760M-P motherboard. The system is built in an older case with no additional case fans, and I'm using only the stock Intel CPU cooler and the fans on the GPU. The stock cooler has always been fairly loud, and the CPU sits around 60°C even in the BIOS, which seems unusually warm.
While playing demanding games such as The Witcher 3 Remastered and Indiana Jones, the CPU fan becomes extremely loud. I believe the CPU is reaching roughly 80°C, although I need to verify the exact temperature with monitoring software. The case also gets noticeably warm. I've tried changing Windows power settings, enabling or disabling processor performance boost, applying a -40 mV VCore offset, and adjusting the fan curve, but none of this has made a satisfying difference.
Would installing a better CPU cooler be enough, or should I also add case fans or replace the case? Are there any safe BIOS settings I should change to reduce temperatures and noise?

The lack of case airflow is probably contributing to the problem. Adding a couple of intake fans and one rear exhaust fan would help remove the heat instead of letting it build up inside the case. A reasonably priced airflow-focused case with fans included can be a good upgrade, especially if the current case has no mounting points or ventilation.
First check the actual CPU temperature with something like HWiNFO while gaming. If it is only reaching around 80°C, the processor still has plenty of safe thermal headroom, so you could lower the fan speed or make the fan curve less aggressive. That said, if the case is getting hot and you want quieter operation, a better cooler is still the more sensible fix than simply slowing the fan down.
A tower cooler would be a worthwhile upgrade by itself, and it does not need to be expensive. Even a budget cooler such as a Snowman-style tower or a Peerless Assassin 120 SE should be more effective and quieter than the stock cooler. Installing one may require removing the motherboard depending on the case and cooler’s mounting hardware, so it would be reasonable to have your dad help with the installation.
The simplest solution is replacing the stock CPU cooler. Intel’s stock cooler is designed to keep the processor within safe limits, but it can get loud while doing so. A basic tower cooler such as a Peerless Assassin 120 SE, or another inexpensive 120 mm air cooler, should be much quieter and provide plenty of thermal headroom. Your i5-14400F is not one of the high-profile instability-affected processors, so the main issue here is cooling and noise rather than the CPU being at risk.
It seems to reach about 80°C, although I need to confirm that. I’m hesitant to lower the fan speed because the whole case gets quite warm during demanding games.
