THE CPU COOLER COLLECTION
Start with your exact processor and the space inside your case. Then check the motherboard, memory and mounting kit before making it yours.
Use the case maker’s CPU-cooler clearance, not its outside width. RAM height matters when a fan sits above the memory.
Browse the photos and specifications below. Add your processor and clearance to evaluate the first fit checks.

Slim single-tower option

For shorter tower clearance

Two fans in a 158mm tower

37mm low-profile AM5 option
Not suitable for processors with high heat loads. Exact CPU compatibility must be confirmed before purchase; AM5 socket fit alone is insufficient.

Large 168mm dual tower
THE LAST CHECK IS THE WHOLE BUILD
Cooler height, RAM overhang and motherboard components can change the fit. CPU performance ratings can rule out a cooler even when it mounts. Every model page links Noctua’s exact compatibility lists, with included parts and limits.
