Intel Core i5-11400

When modern CPUs use their turbo modes, they can (depending on the configuration of the UEFI BIOS) dissipate much more heat than indicated by the manufacturer’s TDP (Thermal Design Power) specification. Just like manual overclocking, this puts higher demands on the cooling solution. Our CPU compatibility list helps you to choose (choosing) the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned.

We classify our coolers according to the following categories:

Note that the turbo/overclocking headroom is classified in relation to the specified base and turbo clock speeds of the CPU, i.e. "compatible without turbo/overclocking headroom" means that a cooler can keep the CPU at base clock and "best turbo/overclocking headroom" means that a cooler can go close to the maximum specified turbo boost speeds. Therefore, if two CPUs are identical except for one having lower clock speeds, the same cooler will score higher on the CPU with lower clock speeds.

For further information on CPUs exceeding their TDP ratings and how to configure the UEFI BIOS in order to avoid excessively high temperatures, please see this FAQ.
