  • Our take on the Noctua NH-L12S

    The Noctua NH-L12S is a low-profile CPU cooler built for small-form-factor and slim cases. It stands 70 mm tall with a single 120 mm fan mounted under the fin stack, so it fits where tower coolers cannot. It uses Noctua's proven NF-A12x15 PWM fan and SecuFirm2 mounting, and it covers Intel LGA115x/1200/1700/2011 and AMD AM2 through AM4. Reviewers rate it highly for quiet operation and build quality, though it trails larger tower coolers on raw heat dissipation and can struggle with high-TDP chips under sustained load.

    What reviewers say

    • 4.8 / 5176 ratings

    Owners and reviewers praise the NH-L12S as one of the best low-profile coolers, citing near-silent operation and easy fit in tight cases. The main complaints are cooling limits on power-hungry CPUs and clearance around tall RAM and motherboard components.

    What people mention
    • NoisePraisedOwners describe it as near-silent at idle and unobtrusive under load.
    • CoolingMixedIt handles mid-range CPUs well but reviewers note limits on high-TDP chips.
    • ClearanceCriticisedThe low fan position can conflict with tall RAM and nearby motherboard parts.
    • BuildPraisedReviewers rate the fin stack and fan quality highly.
    • InstallationMixedMounting is secure but takes patience, especially in small cases.

    Questions and answers

    Is the NH-L12S good for a mini-ITX build?
    Yes. At 70 mm tall it fits many slim mini-ITX cases that reject tower coolers, and it cools mid-range CPUs quietly.
    Will it handle a high-end overclocked CPU?
    Not well. It is designed for low-profile builds, and sustained loads on high-TDP overclocked chips will push temperatures higher than a large tower cooler would.
    Does it fit my socket?
    It supports Intel LGA1155, 1150, 1151, 1156, 1200, 1700 and 2011-3, plus AMD AM2 through AM4. Check your socket against that list before buying.
    Does the fan clear tall RAM?
    The 120 mm fan sits low over the motherboard, so tall heat-spreader RAM can interfere. Low-profile RAM avoids the problem.
    What is in the box?
    The cooler, one NF-A12x15 PWM fan, SecuFirm2 mounting hardware for the listed sockets, and Noctua's usual thermal paste and documentation.
    Is it quieter than a stock cooler?
    Yes. Owners consistently report it runs much quieter than Intel and AMD stock coolers while cooling better.
    Where is the Noctua NH-L12S cheapest?
    At Newegg, for $77.75, as of our latest check.
    What do buyers say about the Noctua NH-L12S?
    Rated 4.8 out of 5 from 176 ratings.
