I used a dual fan setup on my U14 with a standard NF-A15 and an extra one I bought. Both come in a light brown color scheme. At first it didn't bother me at all, but over time the lack of connection with the rest of the black and white components began to bother me. Chromax accessories are quite expensive, especially the fans ($25+ for a fan with colored tabs), but it was worth it in my opinion. My computer now looks fully coordinated and very stylish. The installation process on the cover was also very easy, it only took 2 minutes. Just a plastic cover that attaches to the heatsink, a metal clip that holds the plastic in place, and a cover that slides over the cooler and is held in place by fairly powerful magnets. Definitely recommend. If I ever upgrade to one of the larger dual tower coolers like the D15 or D15s I'll make sure to leave some room in my budget for a Chromax kit to work with it :)
