Up Close

For some strange reason the near flagship Noctua Cooler comes with all it's fittings and accessories packed into one box.  They're all immaculately presented of course, we just think it's odd that coolers further down the model range have theirs in individual boxes.  Talking of boxes, the NH-D15S is another one where it takes a degree in cardboardology (real word, look it up), to get it out of the packaging.

The cooler itself is a bit of a beast, weighing in at 1150g and measuring 160x150x135mm (HxWxD).  It also appears that someone at Noctua has cocked up (sort of).  Read on to find out what we're on about.

Although symmetrical from front to back, the NH-D15S is slightly off-set from left to right.  This off-set helps to improve motherboard compatibility with regards to infringement on the first PCI slot.  Noctua have also recessed the lower fins to help improve RAM clearance

So what's the cock up?  Well take a look at the top of the heat pipes and you'll see that one doesn't protrude as far as the other.  The reason for this isn't that it's shorter than the others, or that it's been fitted wrong, it's actually the same length as the others, but owing to the offset this pipe has further to go.  It's a little thing we know, and although we're calling it a cock-up, invariably it was actually a design decision, to us it looks wrong, and deviates from the sort of attention to detail we expect from Noctua.

The NH-D15S sure does take up a lot of real estate in the case.  Interestingly, even you happen to fit it the wrong way round as we have, it still doesn't obstruct the first PCI slot.  It gets close, real close, but doesn't actually touch it.  As you'd expect, the D15S comes in quite high up the charts, been bettered only by the D14 and the R1 Ultimate.

Had a quick look..
dont see any AIO's in there as a comparison.. I think it would have been nice to see atleast 1-2 of the most popular ones in there, it would just round out the comparisons a bit better imo if you also factor noise efficiency and redundancy.Quote

Great article, good to see my D15 is still a beast in the air cooled department.

One small thing, while reading the D15 page I couldn't help but notice something wrong.

With the front fan installed you are though limited to standard height RAM.
This is actually not the case, the fan can be positioned forward due to the design of the mounting which allows for big RAM if you have the case clearance for the fan to protrude off the cooler.Quote

That explains all the hype around the Cryorig lot, good prices and performance there. Great to see so many all together in one place for comparison.Quote

The BeQuiet coolers are meant to be tightened from the back of the motherboard, not above and between the fins. No wonder you found it hard to do.. If you are saying that poor fitting is the reason they don't perform well, then the test results are not representative of the coolers performance.Quote

I bought the Be Quiet Dark Rock TF for the looks for the Lian Li Q10 build - was supriced that it placed so low.

Have the Raijintek Pallas on my living room rig cooling a G3258 and I thought it was great.Quote
