Noctua NH-U12P CPU Cooler – The Sound of Silence

Jump To:


The Noctua NH-U12P CPU cooler was designed and built in Austria by a team of engineers that have won many international awards for form and function.  Today we look at Noctua’s $75 flagship cooler which features their battle-tested SecuFirm mounting system and the NF-P12 premium fan too keep temperatures not only cool, but quiet.

Noctua NH-U12P

Noctua derived its name from the Greek mythology. The little owl, Athene Noctua, is the symbol of the Greek goddess Athene, who represents wisdom, science and strategy. She has a marked preference for the most clever among the Greek heroes, like Odysseus, who endure their adventures by the use of savvy consideration instead of mere force. It is the owl’s silent flight that Noctua keeps in mind with their fan design, more on that later, let’s look at the specs of the NH-U12P CPU Cooler.
