One of my favorite aspects of this cooler is how you only need to tighten two screws to secure it. And they are not type of screws where you don’t know when to stop, these screws have a stopping point and installation couldn’t be easier.This thing is BIG, the box it comes in is even bigger than this thing cleared my ram and fit my NZXT H7 Elite case just fine. Make sure you didn’t lose your motherboard back plate like I did, my last cooler didn’t require it but when installing this one, I had to rummage through my closets trying to find that small metal back plate. And again, coming from a BeQuiet Hyper or whatever it was called, to this, is a huge difference, especially in size. This thing soaks up the heat.

Ordered this item with some other items at the same time. Package came fast and works great. I use this cooler on a Ryzen 9 5900x CPU and it works very well. Because its the Springtime, where I live is already getting up past 84 degrees. It's a dry heat location and in the full swing of the Summer, temps will be up over 100 degrees. Night times are obviously cooler but not by that much and I do most of my computer work at night anyways. I do work past the sun coming up and even sometimes during mid-day but try to keep most of my work at night. I have less eye strain at night when staring at my monitor than I do during the day.This cooler works very well and I have hit 70C during heavy workloads with only one fan on it. 70C is still very acceptable and I have read ...

My idles were from around 45C to 55C. This was before the rest of my case fans came in though. I have since added a second NF-A15 fan onto the cooler. My temps now run 10C cooler on idle and i haven't hit 70C on heavy loads. And this is with indoor temps being up to 84F. The AC will be running once it gets a lot hotter outside so indoor temps will not be that high. Even up to 70 percent fan speed with my other fans running I still barely hear this cooler. And my PC is directly beside me on a little moving dolly with wheels. 100 percent fan speed is noticeable though but not overbearing.This is a very durable feeling cooler with some weight to it and it feels very balanced in my hand when I was installing it. I like this ''S'' variation because of the side-set design to it. I have a comfortable gap in-between this cooler and my GPU and I have a comfortable space over my RAM sticks. The side-set design also makes it sit more over the top part of the Motherboard instead of it being closer to the GPU like the normal variant. I can rest comfortable knowing that there is space in-between my pc parts. If you have tall RAM sticks it would most likely be best to go with a 120mm fan for the second fan and not the 140mm one like I did. The PC case is the Corsair Crystal Series 680x and I still have room to bump up the second fan another notch or two on the cooler before I won't be able to close my case door.This is a completely new build with all new parts so I haven't tightened up my wires completely yet (had to make sure everything worked first) but there is plenty of space to do so and will be my next step.

For someone considering light to midweight overclocking, I'd recommend this product unless one's going beyond the extreme, after that point, my advise is to consult with someone who knows. I just wanted more out of my i7-4790K, and with this cooler on a ASUS Z97-PRO Gamer & got it, using the ASUS Optimal setting (E-Z one click Tuning). One click & was running at near 4.6GHz in Turbo Mode, running the benchmark sponsored by Intel (HWBOT), had been suffering from thermal throttling, surpassing the 100C mark, the Noctua NH-D15S dropped temps by 30C, no more throttling. I'd venture to say that had I paced just a tiny less thermal paste on the CPU, temps may had dropped further & may do so. Still, 30C is indeed a massive drop on air & can't be overlooked. This is ...

This is probably the best cash that I've ever spent on CPU cooling. And though it's massive when removed from the package, once inside of the Fractal Design Define R5 case, didn't look as big after install. Was able to pull off a great wiring management job, so no clutter, one thing that I need to share before I forget, is to make sure that the case & CPU cooler cables are plugged in before easing the unit down, otherwise, expect some skinned knuckles. One thing that I didn't do was used the included thermal solution, relying on my trusted Arctic MX-4 that I've used for years. With a 8 year warranty against drying out & no issues after install, it's understandable why I chose to stick with what had worked. Prior to MX-4 was MX-2, almost as good & still pre-applied on some coolers. Plus once I have a build complete & setup where I want it, other than routine cleaning, is not moved.

There's no feeling like having removed the bottlenecks of OEM (retail) PC's that cuts corners on vital components to save $5 on a $1,000 PC. Wouldn't had broke the bank of Dell to include twin 4 pin CPU power connectors for a quad core i7 that's still a Top 10 Common CPU. which left it starved for power & the screen froze in place. I figured that to get it right, had to build my own, and I have no formal IT training, just a burning desire to get the most that I can out of my hardware. The Noctua NH-D15S, is a fantastic CPU cooler with the option to add another fan if desired, clips are inside of package.

Running this a 13700 I9 and cool as can be. Give 2 extra clips with the unit as it breaks on install if not super careful, I broke 1 so glad they included them. One thing is that it is HUGE, I mean BEYOND huge and never seen something so big in my life. You must have a good sized case, but I am running mine with a 4080 card in a nice Corsair case. So if you have a smaller case no way, but this fan itself is really wicked for sure!
Some quick HEAVEN 4.0 benchmarks showed the CPU 100% maxed out, and the GPU JUST getting to 100% sometimes. The CPU can’t really keep up with the new 1070ti, and benchmarks show a 50 FPS average using HEAVEN 4.0 maxed out at 2560 x1440. I use an ACER PREDATOR XB271HU 27” 2560x1440 monitor. What to do? Well, over clock the CPU. Intel i7-870 has metal heat spreader and solder interface to get heat out well, but a 95W part has a LOT of heat to get out. I did a quick test at 3.5 Gig on the CPU (160 x22) with 1.25 volt Vcore (speed boost disabled). This, of course, OC’s the memory, too. I could cut the memory ratio and keep the 1600 speed or OC the memory, too. I use GSKILL DDR3 F3-1600C9D-16GXM R. GSKILL F3-1600C9D-16GXM R memory runs at 9-9-9-24 timings @ 1.5V. On a ...

On a hunch, I looked at the specs on the next level DDR3 1866 memory, specifically the HYPER X FURY HX318C10FRK2/16. This runs at 10-11-10-30 @ 1.5 volts. I selected the memory ratio of 6 in by BIOS and manually set the timings to the typical DDR3 1866 level. Presto, it runs at 1926 MHz and passes several MDSCHED.EXE windows memory diagnostic runs. I doubt that the speed difference is worth a hoot on this Intel system truth be told. HEAVEN 4.0 tests show a score of 1572 and 62.4 FPS with the new settings and better yet, the CPU is never at 100% utilization with the GPU hitting 100%, so I get what I paid for on my current platform. It is as good as it will get, for awhile. After gaming for awhile I see 75 C CPU temps in my monitored values with the EVO 212 heat pipe cooler. The COOLER MASTER EVO-212 can JUST keep up in a 70 F room, but as the GPU puts out as much heat as a hair drier on low, and eventually the room gets to 85 F, and the CPU reaches the, to me, limit of 75 C on most cores. The HYBRID cooled GPU is at no more than 48 C and this told me that I can get cooler in an 85 F room…somehow, with the CPU. I didn’t want water cooling, as it is a NOISE and general hassle, as I’ve used it before. Worse, it is expensive ($120.00 average) and I don’t need the level of cooling the better units provide but want better than most single radiator versions. What does air cooling offer? I did the typical search for AIR coolers and the NH-D15S seems the best of the bunch…the biggest, too. The data shows a 30 C advantage to the Cooler Master EVO 212. Another viewpoint is the best value but worst cooling cooler to the worst value but best cooling hierarchy model! If you need it, I guess it is a good value as it keeps my PC going several more years. I moved the top case fan to the front of the case so I have two fans supplying cool air). I removed the radiator bracket from the top of the case then removed the weird screen on top of the case to allow better airflow. Finally I moved the GPU and USB 3.0 daughter cards to the next lower set of 16X and 1X slots to allow ample room under the cooler. I mounted the cooler so the fan faces UP towards the top of the case verses facing the radiator fan out the back. Cool air in the front with 2 x 140 mm fans and heat out the top and back with plenty of room under the GPU to feed the two fans cool air. So now I can KEEP the OC settings full time in an 85 F room and run the 1070ti to it’s fullest potential in my older set-up. This cooler is EASY to install. One hitch. The two screws to mount the cooler to the two MB braces. The first one is easy to start…just DON’T turn the threads in too much. The second screw needs more pressure to PUSH the screw into the brace socket than you might think is right. Too much thread on the first screw only makes this situation worse. I check it over several times for errors. None found. I ditched the supplied screwdriver and got a real one with a decent handle so I could GENTLY press the screw into the socket and get it threaded. Then it is a matter of a turn on one then the other evenly tightening it up till the screw stops. Slightly longer threaded screws and deeper sockets to accept the screws would mitigate this. Not a big deal, but it does make you pause. DOES IT WORK? The Cooler Master EVO 212 hit 75C on max fans in an 84-85 F room with a 3.52 Gig OC and with DDR3 1920 MHz memory OC playing Crysis 3 at 2560x1440 with max details. I average over 60 FPS. With the NH-D15S the CPU hits 55-59 C running 50% fan! With the fans mounted right, so they don't buzz, I see 50 C - 55 C with 87% min fan RPM. GPU is still 55-57 C, same as before so I didn’t hurt that situation any with my CPU cooler orientation. So yes it works. The system idles at 38-40 C with a slow fan speed with 1.25V on the CPU and never gets above 60 C in any load test, so the 50% fan speed is still safely below 75 C, my upper safe limit.
Waited till I had this for a month to determine its merits.The BAD. inner cable to fan gets easily disloged when installing. Had to unclip fan after getting a clicking sound caused by fan blade hitting cable feeding fan motor. (easily fixable but should have a better retention system.)Huge Cooler needs plent of space to have a safe and good fit.The Good. Being so large it can passivly cool at idle states. Large 140mm Fan supplied enough throughput of air for most use cases also will run slower so almost nosieless in daily use.

This is the first time I've installed an aftermarket cpu cooler... Only ever used the ones that came with the processor (which apparently they don't anymore). I've been Argonauting my other PC for 15 years and this is the first completely fresh build since then (though I did bring over the Seasonic 850 platinum rated power supply that I had installed in the old one earlier this year; I put a Corsair 550 in the old one and still use it for mobile recording). This is a workstation on which i do audio work and I'm angling toward silence. It's an i9-10850k 3.6Ghz running at constant 4.8 for stability, and the temperature stays below 50 degrees Celsius easily so far in a dry 70 degree F ambient environment. I am waiting on a set of Noctua case fans and am currently ... MoreThis is the first time I've installed an aftermarket cpu cooler...

This is a workstation on which i do audio work and I'm angling toward silence. It's an i9-10850k 3.6Ghz running at constant 4.8 for stability, and the temperature stays below 50 degrees Celsius easily so far in a dry 70 degree F ambient environment. I am waiting on a set of Noctua case fans and am currently running the new system with the stock fans in the Fractal Define 7 which do not allow motherboard speed control. It's not loud but it's not silent. I made an early attempt to overclock to 5.2 GHz and the system broke to the point of needing to reinstall windows, but otherwise it's been snappy and all programs are running better than I could have imagined before with seemingly no stress on the system. Not sure how much this heatsink has to do with that, but it's definitely not hurting. I guess I should also say that I've never manually overclocked before and thought I should try to get the most out of what I have going on, but might have done something wrong. In any case, I'm sure this cooler was not the reason the 5.2 overclock failed. I'm a little concerned about the weight of the heatsink but honestly once it was put together it seemed like it wasn't pulling on anything too hard. The screw system between the heatsink and the mounts was a little janky coming together... Only two screws, each on opposite sides of the processor. The male side is on the mounting brackets, and on the heatsink itself is a female screw with springs. I'm not sure why there are springs; they may only serve to complicate the process of achieving an optimal mate between the plate on the heatsink and the processor, obfuscating the amount of torque you're applying. Mounting the heatsink to its own brackets was the hardest part. One screw would go in, then I would twist and twist on the other but the screw wouldn't mate with the bolt. I went back and forth several times, easily getting the first screw to engage and being careful not to tighten it any more than necessary for it to simply be engaged, then moving to the other to try to get it to engage and twisting and twisting and it just wouldn't. This process did give me an opportunity to see that I had not applied enough thermal paste, then to see that I had applied too much and wipe it off the edges of things. (Microfiber cloth, 99% alcohol.) Mounting would seem more stable to me if there were four screws through a structure integrated into the heatsink itself and then into the brackets that come in from behind the motherboard, but then it would be less modular and different models would have to be made for different processors and it would probably cost 7x as much and apparently this way is fine so... let's do it. Seems nice, keeps things cool. Just be careful not to bust anything when you're screwing it all together.
I have this CPU cooler supporting my Intel i7-8700k in a Fractal Design Define R6 case (tempered glass version). I also have an EVGA GeForce GTX 1080 FTW2 iCX GPU which also cranks out heat. My case is designed to minimize noise, often at the expense of cooling. That said, I haven't been able to crack beyond 55C on my CPU with this cooler installed, and have a 38C idle temp in a 21C ambient temp setting. I still have the top on my case (so no airflow there) and am just using the three stock 140mm fans that came with my case (two front intake, one rear exhaust). Honestly, without a high-end liquid cooling setup, I don't think you can do much better than this air cooler. So why not five stars?

Honestly, without a high-end liquid cooling setup, I don't think you can do much better than this air cooler. So why not five stars? I have a ASUS ROG Maximus X Hero motherboard (with wifi, although that doesn't really change where things are on the motherboard). The Noctua website notes that this cooler is fully compatible with this mobo. Having installed the CPU, this cooler, and my RAM on the motherboard before installing the motherboard in the case, I spent upwards of an hour combined trying to plug in the CPU fan, plug in a fan hub, plug in CPU power, and install a PCIE M2 SSD. Why? Because there wasn't much space for my big hands to finesse the cables and the M2 SSD cover around the huge heat sink. It can also be tricky to get the top left and middle ATX mobo screws in with the heat sink in the way unless you have a really large case. You need a long and narrow screwdriver (the cooler does come with one, but there's no handle on it). While I was able to get my 1080 graphics card in without too much trouble, I think I'll have to uninstall the CPU cooler if I ever want to take it out...because I can't get enough leverage to push down on the tab and pull it back out (without pulling a chunk of the mobo with it) with the cooler's heat sink in the way. On the bright side, there's actually enough room to install more RAM (even those with large heat sink fins) without having to take out the cooler. Overall, this is an excellent cooler, but if I were doing it again, I would install the cooler after I installed most of the other components, especially the things near the CPU.
Went through 2 AIO’s in 2 years on a Ryzen 7 5800x, decided to switch to an air cooler for reliability and take a hit on the noise and aesthetics. Went with this and with a single fan it’s actually quieter and performs just as well as the Galahad II Trinity 360 it replaced. It fits over tall LED RAM, and takes up most of the space in the case but core temps range from 34 upto 60 on a CineBench run overclocked at 4.7Ghz. In a hot climate with relatively high ambient temps, I’m extremely happy with that.
This thing is an absolute work of art! Was considering a large AIO, and extremely happy I went with air cooling. Moved in rapid succession from an old dying 120mm Corsair AIO, to a Coolermaster Hyper 212 to this, and the difference in build quality and included kit is night and day. Currently keeping an old i7-4770K overclocked to 4.3Ghz (delidded with liquid metal, admittedly) at or below 70C without fail when running Folding@Home 24/7. Idles in the low 30s. Some quick notes specific to the "S" model- -The upward offset away from the PCIE slots puts the top of the heatsink very close to the top of the case if you choose to install it with "Noctua" upright and parallel to the graphics card. Less than 1cm of clearance below 25mm thick fans in a Meshify C case. No ... MoreThis thing is an absolute work of art! Was considering a large AIO, and extremely happy I went with air cooling.

No problem in operation, but makes access to its fan mounting brackets very tricky. -Second set of fan brackets are included; an additional 120mm fan fits on the front above the RAM easily, and lowers temps an additional 3-4C.
