Noctua NH-D15S CPU Cooler Review

When it comes to the “Big Boy’s” of air cooling cooling there are a few names that come to mind, but one that always comes up in discussions is Noctua. There are known for their massive air coolers and their distinctive brown fans. It seems every time we review a Noctua product we are impressed and each product is designed for a specific scenario. This time we have the new NH-D15S, which is much like the NH-D15 that we reviewed about a year ago. The main difference between the two is the NH-D15S has a new offset asymmetrical design that makes more room for memory and PCI-Express card compatibility. Noctua has also removed one of the two fans so you have a center-mounted 140mm cooling fan. The fact that you don’t have a fan on the front or back also helps with compatibility with memory modules. Will these changes affect performance or do we have another winner from Noctua? Read on as we take a look!

Special thanks to Noctua for providing us with the NH-D15S CPU Cooler to review.


We have the same Noctua packaging we have seen the past few years. The front of the box lets us know it is the NH-D15S and lists some of the main features.

One one side of the box you have information on the cooler in a few different languages and on the other you have a full list of specifications and an overview with dimensions.

    Are you sure you installed this the right way around? I thought the whole point of the asymmetrical design was to make it so the first pci slot isn’t blocked at all on just about any motherboard (excluding some itx boards with the slot right next to the socket). I think the intended vertical installation is with it rotated 180 degrees, so it doesn’t block the pci slot and instead extends above the cpu socket.

    You guys know you mounted that heatsink upside down right? It’s offset so you DON’T cover the top pcie slot..

    Good job on the correction with the fitment.

    Okay, this is a little dated but I’ve been waiting along time for the CPU I wanted to find a moderately reasonable price bracket before purchasing at Intel’s over-inflated gouging. So yeah, I’ve had this puppy in my store room for over a year now and the last item on my build list will be, you guessed it… RAM. I’ve made some exhaustive searches using four different engines but still cannot find any satisfactory information regarding using this cooler in conjunction with a full set (8 sticks) of Corsair DDR4 DOMINATOR RAM. Are there clearance issues? What about using it with the fans that come with the RAM? Anyone know?
