Noctua NH-U12S Review
Â
IntroductionÂ
They say that bigger isn’t always better. For the most part I’d have to disagree.  As men we know size matters and that bigger is very often better. Whether it be screen size, memory size, SSD capacity, Overclock, or for that matter even the size of our….Ahem. Yes well, what we’re trying to say here is that we’re pretty much hard wired into a perpetual game of top trumps with all the numbers in our life. Where size does matter though, and where the above rule starts to gain credence, is when size causes a problem, when it causes a conflict, where it gets in the way of other things, or where it’s too large to fit. Imagine that, having one so big that it’s too big to fit…Get your minds out of the gutter, I am of course talking about heatsinks here, and some being too large to fit in your case, fouling your manly large RAM, obscuring your first PCI slot,  or stopping the door from shutting on your super slim case.
Enter then the Noctua NH-U12S at just 158mm tall and a mere 45mm deep without fans there’s no way it’s going to get in the way of your RAM, and unless you’re into uber thin Mid towers you’re going to be hard pushed to find a case that’s too narrow for it.
The sample we have for review comes packaged with a pair of focussed airflow NF-F12 fans, which should make for some interesting temps. Time and testing will tell.
