AI Verdict
This 125mm-tall blacked-out air cooler is a lifesaver for Mini-ITX builders who need to cool a mid-tier CPU without blocking their RAM or GPU slots.
This cooler is a spatial problem solver. You buy it because your case only has 130mm of CPU clearance and your motherboard has zero room around the socket, not because it offers the best price-to-performance ratio.
If your case supports coolers up to 155mm tall, skip this and buy a 120mm dual-tower cooler for half the price.

Pros
- 125mm height fits perfectly in strict SFF cases like the NCASE M1 and NR200
- 95x95mm footprint guarantees zero interference with tall RGB RAM modules or thick GPU backplates
- Includes five soldered copper heat pipes, which is a record number for the 92mm size class
- Bundled AM5 offset mounting bars drop Ryzen 7000 series temperatures by 1-3°C by shifting the cold plate 7mm south over the CCDs
- The NF-A9 fan drops down to 16.3 dBA when using the included Low-Noise Adaptor
Cons
- At $65, it costs $30 more than dual-tower 120mm coolers that offer significantly lower load temperatures
- The matte black chromax coating absorbs skin oils instantly, leaving highly visible fingerprints during installation
- Struggles to keep high-TDP chips like the Core i9 or Ryzen 9 under 85°C without aggressive BIOS undervolting
- Adding a second 92mm fan for a push-pull setup only nets a 1-2°C temperature drop according to forum testing
Dimension Scores
Handles 65W to 105W CPUs perfectly, but the 92mm fan and single-tower design hit a thermal wall past 130W.
The NF-A9 fan maxes out at 22.8 dBA and drops to 16.3 dBA with the included Low-Noise Adaptor.
Features five soldered heat pipes, a nickel-plated copper base, and a black coating that only impacts thermals by 0.1°C.
The single 4-pin PWM cable is sleeved in black rubber and measures exactly the right length to tuck behind an ITX motherboard tray.
Best For
- Mini-ITX builds in sub-15 liter cases like the NCASE M1 where 120mm tower coolers physically cannot clear the side panel
- Motherboards with crowded CPU sockets where standard coolers block the primary PCIe x16 slot
- Cooling 65W to 105W CPUs like the Ryzen 5 7600X or Core i5-13400F in a living room HTPC
Not Recommended For
- Standard ATX mid-tower builds where a cheaper, larger 120mm cooler would provide better thermals
- Overclocking 170W+ flagship processors like the Core i9-14900K or Ryzen 9 7950X
Watch Out For
- The black coating shows every single smudge from your fingers — you must wear gloves or wipe it down with isopropyl alcohol after mounting.
- You are paying a $10 premium purely for the black paint job compared to the standard brown-and-silver NH-U9S.
- Don't bother buying a second NF-A9 fan for the back; user testing shows it barely drops temps by 2°C and just adds unnecessary noise.
- The contact plate isn't perfectly mirror-smooth; it has visible radial machine grooves that Noctua machines intentionally for thermal paste distribution.

What Buyers Say
SFF builders constantly mention this cooler as a necessary spatial compromise for tight cases like the NCASE M1. The SecuFirm2 mounting system gets frequent praise for taking under five minutes to install. The biggest shock for new owners is the fingerprint issue; the matte black finish absorbs skin oils instantly, requiring a wipe-down with alcohol. Many users report running 8-core chips like the 5800X successfully, though they rely on undervolting to keep the 92mm fan from spinning at its maximum 2000 RPM.
“Paid 70 bucks for a tiny cooler because my ITX case demanded it, left greasy fingerprints all over the black paint, but it keeps my 5600x at 65C while gaming so I can't complain.”
Common Praise
- SecuFirm2 mounting system takes under five minutes to install
- 95x95mm footprint leaves zero interference with thick GPU backplates on Mini-ITX motherboards
- Included NT-H1 thermal paste tube provides enough compound for 15 applications
- Fan clips are painted black to match the heatsink perfectly
Common Complaints
- Matte black finish looks terrible if you touch it with bare hands during installation
- Price is hard to swallow for a 92mm cooler when 120mm options cost less
- Fan gets noticeably whiny when pushed to the full 2000 RPM under heavy load
- Base plate has visible machining grooves instead of a mirror polish
Ownership Tips
- The black coating holds up perfectly to heat cycles without flaking or fading.
- Dust buildup is much more visible on the black fins compared to the bare silver version.
- You will likely need to tweak your BIOS fan curves, as the default settings often ramp the 92mm fan up too aggressively.
- The included Low-Noise Adaptor cable is rarely needed unless you are running a 65W CPU in a completely silent room.
Frequently Asked Questions
Can this cool a Ryzen 7 5800X or 7800X3D?
Yes, but expect load temperatures in the high 70s to low 80s. You will need to adjust your BIOS fan curve to hit 100% speed earlier.
Does the black coating ruin the cooling performance?
No. Noctua's testing and independent reviews show the chromax.Black coating only increases temperatures by 0.1°C compared to the bare metal version.
Should I add a second fan for push/pull?
Save your money. Multiple user tests show adding a second rear fan only reduces temperatures by 1 to 3 degrees Celsius.
Will this block my RAM slots?
Not at all. The 95x95mm footprint stays strictly within the Intel and AMD socket keep-out zones, giving you 100% clearance for any RAM height.
Does it come with thermal paste?
Yes, it includes a full-sized tube of Noctua's NT-H1 thermal compound, which provides enough paste for about 15 applications.
Is the AM5 offset mount included in the box?
Yes, current retail boxes include the offset mounting bars that shift the cooler 7mm south to sit directly over the Ryzen CPU hotspots.
Buying Guide
You are buying this cooler for one reason: physical dimensions. In the world of PC cooling, surface area dictates performance, and a 92mm cooler will always lose to a 120mm cooler in raw heat dissipation. Check your PC case's maximum CPU cooler height specification before buying. If your case allows for 155mm or taller coolers, you are wasting money here. If you are restricted to 130mm or less, this is the highest-quality air cooler you can physically cram into that space.
125mm Height
This is the physical distance from your CPU to the case side panel. Think of it like a bridge clearance; if your case only allows 130mm, a standard 155mm cooler will prevent you from putting the side panel back on.
95x95mm Footprint
This dictates how much space the cooler takes up around the CPU socket. A 95mm square means the metal fins won't hang over your RAM sticks or bump into your graphics card.
5 Heat Pipes
These are the copper tubes that pull heat away from the CPU up into the metal fins. More pipes mean faster heat transfer, and 5 is an unusually high number for a cooler this small.
Alternatives
If your case has at least 155mm of clearance, search for a '120mm dual-tower air cooler' to get vastly better temperatures for half the price. If you need something even shorter than 125mm, look for a 'low-profile downdraft CPU cooler'.
