One of U14S’s biggest selling points is the slim design. Noctua have engineered this heatsink to cater for maximum memory compatibility on all socket types but more importantly LGA2011 – which has memory slots on either side. (More on this later in the review).
The U14S heatsink measures 165 mm in height, 150mm in width and 52mm in depth. Weighing 770g, It uses copper for the baseplate and heat-pipes, aluminium for the cooling fins with nickel plating.

Utilising a total of six copper heatpipes, the U14S may have the dimensions and single tower specification which is customary to the U-Series but it still promises to deliver high-end performance. The heatpipes are positioned in eclipse type alignment rather than in a straight line, this is more noticeable when observing the heatsink from an aerial point of view.
U14S’s baseplate uses copper and has the mounting plate already fixed for easy installation. The surface finish on the baseplate is semi-transparent, meaning there is no mirror finish.

To attach the NF-U15 to the heatsink, Noctua have given the fan an ingenious clip to provide a secure fitment. These fan clips whilst being very easy to fit offer a firm attachment.
Noctua provide fan clips for attaching another cooling fan to the U14S, the heatsink can accommodate: 140x150x25 (with 120mm mounting holes), 140x140x25 (with 120mm mounting holes), 120x120x25.
Easy to use fan clips are fast and effective
