Noctua NH-C14S CPU Cooler Review @HiTech Legion
 

"The transformation of the NH-C14 to the NH-C14S was a very slight one. The tower simply needed to be shifted slight over, and at first glance the differences are nearly imperceptible. Thankfully the performance differences are imperceptible, as well, leaving you with simply a more compatible NH-C14. That said, the NH-C14S sits firmly atop the performance charts of top down coolers at any price. Mind you, pricing also sits atop that chart, but at $79.95 retail it is more than fair."
