Do you need a CPU cooler for a PC build?

Yes, a CPU cooler is essential for a PC build, as it helps dissipate heat generated by the CPU during operation. Without proper cooling, the CPU can overheat, leading to thermal throttling or potential damage. While some CPUs come with stock coolers, aftermarket coolers can provide better performance and quieter operation, especially for overclocking or high-performance builds. Always ensure your cooling solution is compatible with your CPU and case.
