Noctua has released its NH-D15S to stand alongside its NH-D15. The NH-D15 is a huge heatsink, a full 15cm wide. The NH-D15S looks like the D15’s twin, also 15cm wide. Where do the two differ? The NH-D15S is moved over to make more room for the first PCIe slot, and it comes with one fan, not two – this keeps the price down.
Not all cases have room for a full tower heatsink. So, Noctua provides a blow-down variety with six heat pipes and a 140 mm fan. That was the NH-C14, and it is quite a cooler. So, what’s new? The NH-C14S (note the change in the model number), with the finstack moved over to make room for cards in the top PCIE slot. How well does this heatsink cool? Let’s find out.
