Noctua claims that due to a fine-tuned design and the NF-F12 120mm FocusedFlow fan, the NH-U12S further improves the cooling performance of the NH-U12P SE2. The NH-U14S features a large, six heatpipe design and comes equipped with the NF-A15 140 mm fan.
Both the NH-U12S' NF-F12 and the NH-U14S' NF-A15 fan support PWM for automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 1500 to 1200 rpm using the supplied Low-Noise Adaptor for even quieter operation.
The NH-U12S and NH-U14S feature a slim layout that has been conceived to provide maximum RAM compatibility: With a fin depth of only 45 mm, the NH-U12S will not overhang the RAM slots even with two fans installed. The NH-U14S features a 52 mm slim design tailor-made for LGA2011 and does not overhang the RAM slots on this platform.
The new coolers use Noctua's SecuFirm2 multi-socket mounting system, they are bundled with Noctua's NT-H1 thermal compound and are backed by a 6-year warranty.
The NH-U12S and NH-U14S will be available shortly at suggested retail prices of EUR 59.90 / USD 64.90 (NH-U12S) and EUR 69.90 / USD 74.90 (NH-U14S).
