At idle, the performance of the Noctua NH-U12S is indeed impressive. Then again, it’s the load temperature that enthusiasts are more concerned about. Let’s have a look at the load temperatures obtained:
Here, the Noctua NH-U12S is far from impressive, in fact it exceeded my expectations. Despite being a conventional, single tower design with a single fan, it is a stellar performer, competing and performing better than the highly sought Noctua NH-D14. The secret behind this lies in the engineering of the fan, thereby optimizing air flow direction and volume of air passing at a relatively low RPM. Expect these figures to be further impressive with a second fan in a push-pull configuration!
