Noctua are considered a top brand when it comes to the cooling department. Their unique colour scheme and product naming set them apart from rivalling companies and over time Noctua products have been granted some of the highest accolades out there. The NF-S12 fan was an instant success and further showcased Noctua's ability in this market. Recently this particular fan has been updated with two new versions: the NF-S12B FLX and ULN. Today, we take a look at the FLX version which features high versatility; one can only hope it is half as good as its predecessor.
