I saw a review and it pretty much said the black d15 didn’t perform as well as the original while the other black one performed slightly better than the original. Not sure what the coating is, but I don’t need one so I’ll pass. I was hoping for an extra heatpipe but I guess they are satisfied with 6. I wonder if they have played with larger diameter pipes. Seems like only a few have used 8mm pipes. I wonder if it’s a bit tougher getting a good coldplate with larger pipes than 6mm.
The D15 does come with 1500 RPM fans vs 1200 RPM fans on the normal version, not sure why they are different but for any variance that could be part of the reason why.
There is mentioning of NH-D15S chromax, unless I'm seen it wrong I don't see no "S" version. I'm wondering if they will make their new 7 heat pipe NH-DxxS black and org. whenever that might be, apparently in second Q of 2020..long way
With all the variables involved in testing cooler performance like how well the cooler mates to IHS, air temp into cooler, differences in fan speed, etc. can easily account for a few degrees.
I'm guessing the coating is not effecting cooling any or enough to measure. Difference in temps caused by how well cooler base mates to IHS will be much greater than coating vs no coating. Keep in mind tea- kettles are usually have polished finishes to keep heat in better and heating stoves usually have matt /dull finishes to radiate heat better.
Pretty sure he was talking about the LTT review.
They concluded that the difference was due to differences in fan speeds and that the coolers itself where within margin of error of each other. So the coating most likely doesn't make a difference.
This is long past about time. Noctua has a habit of promising something, then taking their sweet time delivering. Look at how long it took for Noctua to deliver the Chromax covers after first introducing at one of the trade shows (and introducing it again...).
They sure do love taking their time. im still waiting on their active noise canceling fans they announced back in 2012!
All Noctua coolers using 140mm fans (NH-D15 and NH-D15 chromax.black, NH-U14S & NH-U14S TR4-SP3) come with 1500rpm version of NF-A15 PWM or NF-A15 PWM chromax.black fans. Both NF-A15 PWM and NF-A15 PWM chromax.black supplied on coolers are 1500rpm fans.
But retail version of NF-A15 is 1200rpm .. So if you want a 1500rpm NF-A15 fan you have to buy a cooler to get it. Noctua might sell one to consumer who owns a cooler that came with NF-A15 1500rpm fans if cooler is out of warranty, but I know they won't sell them to NH-D15S or NH-U14S owners because I know owners who have to get NF-A15 PWM 1500rpm fans and couldn't.
