Here are some tips to keep your Intel Core i7-14700K cool:

1. Use a high-quality CPU cooler:

   • Choose a reliable air cooler or an All-In-One (AIO) liquid cooler with a sufficient TDP rating to handle the i7-14700K's heat output.
   • Ensure proper installation with even thermal paste application.

2. Ensure adequate case airflow:

   • Install intake fans at the front and exhaust fans at the rear and top of the case.
   • Maintain a positive air pressure balance to minimize dust buildup.
   • Consider adding a fan controller to optimize fan speeds based on temperature.

3. Apply thermal paste correctly:

   • Clean the CPU and cooler surfaces before applying a small amount of high-quality thermal paste.
   • Spread the paste evenly using the appropriate method (e.g., pea-sized dot, cross, or spread).

4. Monitor temperatures and adjust fan curves:

   • Use software like Intel XTU, HWiNFO, or BIOS settings to monitor CPU temperatures.
   • Adjust fan curves to find the right balance between cooling performance and noise levels.

5. Undervolt the CPU (optional):

   • Carefully undervolt the CPU to reduce heat generation without sacrificing performance.
   • Use tools like Intel XTU or BIOS settings, and test for stability.

6. Maintain a clean environment:

   • Regularly clean the PC case, fans, and heatsinks to remove dust and debris.
   • Ensure the room temperature is not excessively high.

By following these tips and using appropriate cooling solutions, you can effectively manage the temperatures of your Intel Core i7-14700K and ensure optimal performance and longevity.

I'd recommend upgrading to a better air cooler like the Noctua NH-D15 or be quiet! Dark Rock Pro 4. Those will give you much better cooling performance and acoustics compared to the Intel stock cooler. Make sure your case has decent airflow too.

Make sure your case has good overall ventilation, not just focused airflow over the CPU. Having some top exhaust fans helps hot air escape.
