AI Verdict
A dual-tower air cooler with 8 heatpipes and two 140mm fans, designed for high-end AMD AM5/AM4 and Intel LGA1851/LGA1700/LGA1200 CPUs.
This cooler is a strong fit for high-performance desktop systems needing top-tier air cooling for CPUs like the Intel 14900K or AMD 9950X3D. Its 8 heatpipes, 20% increased surface area, and two 140mm NF-A14x25r G2 fans deliver cooling performance that rivals some 360mm AIOs. The offset design also helps with PCIe clearance, a common issue with large air coolers.
If case compatibility is a concern, look for coolers with a height under 160mm and a single-tower design.

Pros
- Delivers outstanding cooling performance, maintaining 242.6 watts on AMD and 323.0 watts on Intel test benches, rivaling some 360mm AIOs.
- Operates exceptionally quiet, especially at mid-fan speeds, with a well-behaved airflow sound at maximum RPM.
- Includes two NF-A14x25r G2 140mm fans with PWM, Low-Noise Adaptors, and speed-offset for acoustic fine-tuning.
- Offset design provides 59mm RAM clearance in single fan mode and clears the top PCIe x16 slot on most motherboards.
- Comes with superior NT-H2 thermal paste, an AM5 thermal paste guard, and a Torx-based SecuFirm2+ mounting system with an NM-SD1 screwdriver for easy installation.
- Backed by a 6-year warranty and Noctua's reputation for long-term product support.
Cons
- Offers only 32mm RAM clearance when both 140mm fans are installed, potentially limiting RAM choice.
- Large physical dimensions (168 x 150 x 152mm with fans) can lead to tight fits or incompatibility with smaller cases.
- The $150-$299 price point is significantly higher than other air coolers that offer similar thermal performance.
- Fans can become the loudest component in a build when operating at 950-1000 RPM or higher.
Dimension Scores
It maintains 242.6 watts on AMD and 323.0 watts on Intel test benches, often outperforming or matching 360mm AIOs.
The NF-A14x25r G2 fans are exceptionally quiet at mid-speeds, producing a well-behaved airflow sound at max RPM, though audible above 950 RPM.
Features a soldered assembly, nickel-plated copper base, and a robust Torx-based SecuFirm2+ mounting system, backed by a 6-year warranty.
Includes a 4-pin PWM splitter cable for managing the two fan connections, which is standard for dual-fan coolers.
Best For
- High-performance AMD Ryzen (e.g., 9800X3D, 9950X3D) and Intel Core/Core Ultra CPUs (e.g., 14900K, 13900K) requiring robust air cooling.
- PC builds prioritizing quiet operation, especially at idle and mid-loads, with automatic fan speed control.
- Users seeking a premium, all-black aesthetic for their cooling solution.
- Builders who value long-term product support and a 6-year warranty.
Not Recommended For
- Small form factor (SFF) PC builds due to its large 168 x 150 x 152mm dimensions.
- Users with tall RAM modules (over 32mm) who intend to use both 140mm fans in their standard configuration.
- Budget-constrained builds, as its price is significantly higher than competitors offering comparable thermal performance.
Watch Out For
- The cooler's large size (168 x 150 x 152mm with fans) can make for a tight fit in cases like the Meshify 3, requiring careful planning for component clearance.
- RAM modules taller than 32mm will interfere with the front 140mm fan when both fans are installed, necessitating single-fan operation for 59mm clearance.
- While quiet at lower RPMs, the NF-A14x25r G2 fans can become the loudest component in a system when they kick in at 950-1000 RPM or higher.
- The $150-$299 price range is considerably higher than competitors like Thermalright's Phantom Spirit 120 EVO or ID-Cooling's FROZN A620 PRO SE, which offer similar thermal performance for under $50.

What Buyers Say
The most striking feedback is that this air cooler delivers thermal performance comparable to some 360mm AIO liquid coolers, particularly on high-wattage CPUs, while maintaining a quiet noise profile at most fan speeds. However, this top-tier air cooling comes at a price point that many reviewers find difficult to justify, especially when significantly cheaper air coolers offer nearly identical thermal results. The installation experience is consistently praised for its ease and included accessories.
“Dude, this thing cools my 9950X3D like a champ and it's so quiet at idle, but man, my wallet took a hit and those fans can get a bit whiny when I'm really pushing it.”
Common Praise
- Maintains high TDPs, like 242.6 watts on AMD and 323.0 watts on Intel, rivaling 360mm AIOs.
- Fans produce a well-behaved airflow rush rather than an intrusive mechanical whine, especially at mid-speeds.
- SecuFirm2+ mounting system with Torx screws and included screwdriver makes installation straightforward and secure.
- Includes a comprehensive accessory bundle, including NT-H2 thermal paste, low-noise adaptors, and an AM5 paste guard.
- The all-black chromax aesthetic is visually appealing for many builds.
- Backed by a 6-year warranty and Noctua's reputation for long-term support.
Common Complaints
- The $150-$299 price is considered prohibitively expensive when compared to air coolers under $50 that offer 98% of the performance.
- Fans can become audibly loud, described as the "loudest fans in my build," when operating at 950-1000 RPM or higher.
- The cooler's large physical size (168 x 150 x 152mm) can lead to clearance issues with RAM modules (only 32mm with both fans) and case side panels.
- Some users report a "rattling issue" though this is not a widespread complaint.
Ownership Tips
- The included low-noise adaptors are useful for fine-tuning acoustics if the fans become too loud at higher RPMs.
- Careful measurement of RAM height and case width is crucial before purchase to avoid clearance problems.
- The Torx screwdriver included in the package is genuinely helpful and makes installation less frustrating than with standard Phillips head screws.
- The all-black finish holds up well over time, resisting dust and fingerprints better than bare aluminum.
- Even with its size, the offset design does a good job of clearing the top PCIe slot, which is a common concern.

Buying Guide
When you're looking at a CPU cooler, especially for high-end processors, you're balancing how much heat it can move away from your CPU (thermal performance) with how much noise it makes doing it. Air coolers like this one are often more reliable long-term than liquid coolers because they have fewer points of failure. You also need to think about how big the cooler is and if it will actually fit in your computer case and clear your RAM sticks.
cooling_method (Air)
This means it uses metal fins and fans to dissipate heat directly into your case, unlike liquid coolers that pump heat to a radiator. Air coolers are generally simpler, more reliable, and don't have pump noise.
wattage (2.28 watts)
This refers to the power consumption of the fans, not the cooling capacity. For cooling capacity, you'd look at the CPU's Thermal Design Power (TDP) that the cooler can handle, which for this cooler is very high, handling 242.6W on AMD and 323.0W on Intel.
fan_size (140mm)
Larger fans can move more air at lower RPMs, which usually translates to quieter operation compared to smaller, faster-spinning fans, but they also require more physical space.
Alternatives
If this cooler is too large for your case or too expensive, look for dual-tower air coolers with a height under 160mm or single-tower coolers with 120mm fans, or consider more budget-friendly dual-tower options that offer similar thermal performance.
