Pros
- Features a magnetic top cover ARGB digital display board that shows CPU and graphics card temperature and occupancy information.
- Includes dual fans (120mm and 140mm) with S-FDB bearings and PWM intelligent temperature control for efficient heat dissipation.
- Offers wide compatibility with AMD AM4/AM5 and Intel LGA1851/1700/1150/1151/1155/1156/1200/2011/2066 sockets.
- Soft corner pads around the fans reduce vibration noise during operation, contributing to a ≤29.6/25.6DB(A) noise level.
- Installation is straightforward with SS2 fasteners and includes a Y-adapter for connecting both fans to a single motherboard interface.
Cons
- The overall height of 165mm means it might not fit in all PC cases.
- The 120mm fan may need to be adjusted or raised to clear tall RAM modules.
- AMD platform installations require the use of the motherboard's original backplate, which is not included.
- The TRCC control software for the ARGB digital display is described as very basic, with limited customization options.
Dimension Scores
The cooler features dual fans (1850/1500RPM, 82/77.8CFM airflow, 2.1/2.09mm H2O wind pressure) and six 6mm copper heatpipes, providing high cooling performance comparable to more expensive options.
With operating noise levels of ≤29.6/25.6DB(A), S-FDB bearings, and soft corner pads, users consistently report quiet operation even when under load.
Constructed with aluminum fins, copper heatpipes, and S-FDB bearings, the cooler feels sturdy and well-built, not cheap or flimsy.
The inclusion of a Y-adapter allows both fans to connect to a single motherboard header, simplifying cable routing.
Best For
- PC builds with high-TDP CPUs that need effective air cooling without breaking the bank.
- Users who want real-time CPU and GPU temperature monitoring directly on their cooler.
- Builders seeking a cooler that is compatible with a broad range of current Intel and AMD platforms.
- Systems where quiet operation is a priority, even under load.
Not Recommended For
- Small form factor (SFF) PC cases due to its 165mm height.
- Users who expect extensive software control and customization for their cooler's display.
- Builds with extremely tall RAM modules where fan adjustment might not be sufficient or desired.
Watch Out For
- The cooler's 165mm height can be a tight squeeze or outright incompatible with many mid-tower and smaller cases, so you need to check your case's CPU cooler clearance before buying.
- If you have tall RAM sticks, the front 120mm fan might sit too low and require you to raise it, potentially impacting aesthetics or overall height.
- For AMD installations, you'll need to use your motherboard's existing backplate, as the cooler doesn't come with one for AMD platforms.
- The TRCC control software for the ARGB digital display is pretty barebones; don't expect a ton of fancy features or deep customization beyond basic temperature and occupancy display.

What Buyers Say
What really stands out is how this cooler punches above its weight class; users are consistently blown away by its cooling performance, often comparing it to much pricier alternatives like the Noctua NH-D15. The ARGB digital display on top is a definite crowd-pleaser, giving you real-time CPU and GPU temperatures without needing extra software open. Installation is surprisingly easy for a dual-tower cooler, which is a huge plus. However, its substantial 165mm height means you absolutely need to double-check your case clearance, and the display's software is pretty basic.
“Dude, this thing cools my Ryzen 7 9800x3D like a champ, even playing 4K games, and it barely makes a peep! For the money, it's kinda insane how well it works, just make sure it fits your case first.”
Common Praise
- Keeps CPU temperatures low even during intense gaming sessions and under heavy loads.
- Operates quietly, with users noting it's not unnecessarily loud even when fans are set to silent profiles.
- The ARGB digital display board provides useful real-time CPU and GPU temperature and occupancy data.
- Installation is straightforward and hassle-free for both Intel and AMD platforms.
- Offers exceptional cooling performance for its price point, making it a strong value proposition.
Common Complaints
- The 165mm height can be problematic for some PC cases, requiring careful measurement before purchase.
- The 120mm fan might interfere with tall RAM modules, potentially needing to be raised.
- The software for controlling the ARGB digital display is very basic and lacks advanced customization options.
- AMD installations require the motherboard's original backplate, which isn't always explicitly clear to new builders.
Ownership Tips
- The S-FDB bearings in the fans contribute to long-term quiet operation and durability, which is something you notice after months of use.
- The digital display, while basic, is genuinely useful for a quick glance at system temps without needing to tab out of games or apps.
- Dust accumulation on the large heatsink fins is something to keep an eye on, as with any air cooler, and regular cleaning helps maintain performance.
- The sheer size of the cooler means it can dominate the aesthetic of your build, which some users love and others find imposing.
Frequently Asked Questions
What CPU sockets is this cooler compatible with?
It's compatible with AMD AM4/AM5 and Intel LGA1851/1700/1150/1151/1155/1156/1200/2011/2066 sockets, covering a wide range of modern CPUs.
How tall is the cooler, and will it fit in my PC case?
The cooler has an overall height of 165mm. You should measure your PC case's CPU cooler clearance to ensure it will fit, as this is a relatively large cooler.
Does the digital display show CPU temperature?
Yes, the ARGB magnetic digital display board can show the temperature and occupancy information for both your CPU and graphics card.
How loud are the fans?
The operating noise levels are rated at ≤29.6DB(A) for the 120mm fan and ≤25.6DB(A) for the 140mm fan. Users report it runs quietly, even under load.
Is installation difficult?
Installation is generally considered straightforward, with SS2 fasteners and clear instructions. It also includes a Y-adapter for fan connections.
Buying Guide
When you're looking at CPU coolers, you're basically trying to keep your processor from overheating, which can cause performance drops or even damage. Air coolers like this one use fans and metal fins (a heatsink) to pull heat away from the CPU. The bigger the heatsink and the more powerful the fans, generally the better the cooling, but also the larger the physical size.
Fan Speed (RPM)
This tells you how fast the fans spin. Higher RPM usually means more airflow and better cooling, but it can also mean more noise. This cooler's fans run at 1850/1500RPM, which is a good balance for cooling and noise.
Airflow (CFM)
CFM stands for Cubic Feet per Minute, and it measures the volume of air the fan moves. More CFM means more hot air is being pushed away from the heatsink, directly impacting cooling efficiency. This cooler moves 82/77.8CFM of air.
Noise Level (dB)
Measured in decibels (dB), this indicates how loud the cooler's fans will be. Lower numbers are quieter. This cooler's fans operate at ≤29.6/25.6DB(A), which is relatively quiet for its cooling power.
Overall Size (140x160x165mm)
These dimensions are crucial for physical compatibility with your PC case and RAM. A cooler that's too tall (like this one's 165mm height) won't let your side panel close, and a too-wide cooler can block RAM slots.
Alternatives
If this cooler is too large for your case, look for air coolers with a height under 160mm. If you need even higher cooling capacity for extreme overclocking or prefer a different aesthetic, consider an All-in-One (AIO) liquid cooler with a 240mm or 360mm radiator.
