Noctua also sent out a Noctua NA-HC4 chromax.white heatsink cover kit for the D15S. The chromax series of heatsink covers is one of those rare ideas that takes an existing flagship product and without altering it, improves upon it without compromising the products’ greatest qualities.
Finally, slide a cover over each fixture and the magnets do the rest. It’s that easy! You don’t have to detach the fan and can even do this while the heatsink is installed on the motherboard. Amazing! After seeing the chromax heatsink cover in person, I can’t imagine building with it. While most aesthetic add-ons are a waste of money, the NA-HC4 can be seen and enjoyed every day if you are one of the many with a case that has a tempered glass side panel. The sheer quality of the covers and the stark change they have on the looks of your PC is well worth the price. Performance The box for the Noctua NA-HC4 chromax.white maintains the same aesthetic as other Noctua product boxes and displays the compatible heatsink model numbers on the front.We utilized an Intel Core i7-10700K for this test and used the factory CPU settings of 3.8GHz at 100% load to put the cooler to the test. The second and third tests were performed with an OC stage of 4.7GHz and 5.0GHz, respectively. We wanted to see how well the Noctua NH-D15S performed in standard and high-end OC modes. Upon removing the D15S heatsink from its box, I was amazed at its sheer bulk. This is a serious heatsink and it oozes quality. This is a heatsink you buy once and will re-use again every time you upgrade your system. One aspect of Noctua’s heatsinks has not changed: the NH-D15S like the –D15, the –C14S, the -D14 and others, all use the SecuFirm system. If you mount one heatsink, you can swap it for another Noctua heatsink in minutes. They make a reviewer’s job much easier. NH-D15S Pros You have limited space: This cooler, although not exceptionally heavy, is quite large in size. If your PC case has limited space, it may not fit comfortably, so consider the available space in your case before purchasing. Inside, we find squishable foam – my favorite kind. The foam has some give to it and doesn’t break like Styrofoam. The foam surrounds fully recyclable boxes. But you are not going to recycle perfectly good boxes that were custom built for this heatsink and its accessories. The whole thing goes together too nicely. You will keep your box.
The NH-D15S is at least as good as its predecessor, the NH-D15. It accomplishes Noctua’s main aims of making more room for a 1 st-slot card, bringing down the cost of the cooler, and making this heatsink truly compatible with tall RAM.The stress tests were carried out with AIDA64 Extreme. We went with the Thermaltake View 71t instead of an open-bench setup. Three intake fans are located in the front of the Thermaltake View 71t, while one exhaust fan is located at the rear. Those two threaded rods were for the tensioning screws. Noctua provides an L-shaped screwdriver for tightening the tension bolts. However, you would do well to get a 200mm long-shaft #2 Phillips screwdriver. Very helpful for this and for tightening motherboard screw deep in a case. If we installed a 2 nd fan, the D15S might even surpass an AIO. So, if you are after the highest possible performance and feel you must have an AIO to attain it, think again. Compatibility: Intel LGA 2066/2011-0/1155/1156/1150/1200/1700 and AMD AM5/AM4/AM3+/AM3/AM2+/AM2/FM1/FM2/FM2+
Finally, a second box under the fan tray has the additional anti-vibration pads necessary for installation in every color. There are also four mounting screws if the fan is to be installed in a case. A low-noise adapter is also included. However, even more impressive is our 79° temperature during 100% load! Just as with our idle temperatures, the D15S stayed in range of a high-quality 240mm liquid cooling unit, no pump noise necessary!You prefer low noise levels: This cooler is equipped with a quality NF-A15 fan for improved and quieter performance, making it ideal for users who prefer a quieter PC environment. In essence, I tried to do all the things you might find logical to try. I used two different mounts to compare the cooling. I mounted the NH-D15S a third time with the fans blowing up – I had recently tested the NH-C14S heatsink and found a 5 degree difference in cooling, depending on how I mounted it. So I tried this vertical mount to see if it made a difference in how well the D15S cooled. The results are presented in different charts to keep the different mounts separate. Attach the fan to the cooler as previously, making sure it is facing the desired direction ( airflow arrows can be seen on the side of the fan). Connect the fan to the 4-pin PWM connector once it’s been installed. Upon removing the heatsink covers, you’ll notice a gray fixture on the underside of each cover. If you pull away in the corner, the fixture will come off as you break the connection of the magnets holding it in place.
