Noctua NH-U12S Review

Noctua NH-U12S

Closer Look at the Cooler:

Completely preinstalled out of the box, the NH-U12S is a mere 158mm tall, thereby fitting in most compact cases without trouble.

Looking from the side, it is evident that the fan extends slightly beyond the heatsink. This ensures heat-transfer efficiency. Despite this, the total depth is just over 70mm, resulting in 100% memory compatibility.

Additionally, the fan clips that hold the fan in place are also visible. They lock into the grooves of the cooler, thus maximizing the effective airflow. The fan comes with padding material installed at corners to dampen any vibrations.

The heatsink consists of a standard tower design comprising of 50 identical aluminum fins. Each of these fins has ‘Noctua’ etched onto them alongside company’s logo.

From this angle, it can be seen that the symmetrical fins have a rather ‘curved’ profile with serrated, tooth like sections where the majority of the heatpipes go. This is done to ensure maximum airflow in areas that are likely to be the hottest whilst keeping the setup silent.

Primarily, the CPU block consists of 5 evenly spaced nickel-plated copper pipes which are tightly sandwiched between two neatly machined nickel-plated copper plates. Each of the pipes passes through the stack of fins before protruding out of the top.

The base touching the processor has arched grooves so as to maximize the effective contact with the processor when thermal-paste is applied.

Additionally, Noctua has screwed the top mounting plate onto the cooler by factory. Not only does this make installation a lot easier, it also serves to ensure pressure is applied evenly when tightened.

At a first glance, nothing unique can be seen in the fan bundled with the cooler (Noctua NF-F12). Following the traditional brown-and-beige color scheme, the fan may come off as ‘boring’. Regardless, it is engineered to deliver 55 CFM of air at just 1500RPM, in the process producing a mere 22.4 decibels of noise!

Turning the fan over, serrated struts are visible on the sub-frame assembly. Not only does this maintain proper static pressure, it also keeps the noise produced in check.
