AI Verdict
A 47mm low-profile air cooler with a 92mm PWM fan, designed for compact ITX and HTPC systems up to 125W TDP.
This cooler is a strong fit for its intended purpose: extremely compact ITX and HTPC systems. Its 47mm height directly addresses the primary constraint of these builds, and its 125W TDP rating is suitable for many mainstream CPUs used in such systems.
If you need more cooling capacity for a higher TDP CPU in a compact build, look for coolers with a slightly taller profile (e.g., 53mm) or a full copper heatsink variant.

Pros
- Total height of 47mm fits extremely tight ITX and HTPC cases without memory clearance issues.
- Includes a 92mm TL-9015 PWM fan with a maximum rotational speed of 2700 RPM for automatic temperature control.
- Features 4x6mm heat pipes with AGHP technique to maintain cooling efficiency regardless of orientation.
- Compatible with a wide range of Intel (LGA1700/1150/1151/1155/1156/1200) and AMD (AM4/AM5) sockets.
- Outperforms stock Intel coolers, keeping CPUs like the i5-12400 cooler and allowing for better performance.
- Installation is straightforward with metal mounting fasteners and retention clips.
Cons
- Maximum noise level of 22.4 dB(A) at 2700 RPM can be noticeable under load.
- Rated for 125W TDP, which may limit performance with higher-wattage CPUs, potentially leading to clock speed reductions.
- AM5 mounting might require minor modification to the motherboard backplate for nut clearance.
- Stock fan, while effective, can be louder than premium aftermarket alternatives.
Dimension Scores
The cooler manages 125W TDP within a 47mm height, outperforming stock coolers and handling some higher-TDP CPUs at stock settings.
The 92mm fan operates quietly at idle but can reach 22.4 dB(A) at 2700 RPM under load, which is audible.
It features 4x6mm copper heat pipes with AGHP technology and a robust aluminum fin stack, giving a sense of solid construction.
The 4-pin PWM fan cable is standard, and the compact size means minimal cable interference within the case.
Best For
- Small Form Factor (SFF) PC builds with strict height limitations (47mm clearance).
- HTPC (Home Theater PC) systems needing quiet operation at idle and compact cooling.
- Budget-conscious ITX builds using CPUs with up to 125W TDP.
- Upgrading from an Intel stock cooler in a compact system.
Not Recommended For
- Overclocking high-end CPUs (e.g., 170W+ TDP) in any form factor.
- Users prioritizing absolute silence under heavy CPU load.
- Systems where a larger tower cooler can fit and offer superior cooling performance.
Watch Out For
- The 92mm fan can get loud, reaching 22.4 dB(A) at its maximum 2700 RPM, which some users find distracting.
- While rated for 125W, pushing CPUs near or above this limit, such as a 5900X at stock settings, can result in CPU package temperatures around 80°C and reduced clock speeds.
- AM5 motherboard installations may require slight filing of the stock backplate to ensure proper nut fastening.
- The included thermal paste is effective, but some users might prefer to use their own high-performance paste for marginal improvements.

What Buyers Say
Many users building small form factor PCs praise this cooler for its ability to fit into extremely tight spaces, specifically its 47mm height, which is a critical factor for ITX cases. It consistently outperforms Intel's stock coolers, providing better thermal management for CPUs like the i5-12400. However, some users note that while it can cool higher-wattage CPUs, it might lead to clock speed reductions to maintain acceptable temperatures. The stock fan is effective at moving air but can become noticeably loud when running at its maximum 2700 RPM.
“Dude, this thing actually fits in my tiny ITX case, and my i5 isn't cooking anymore, but man, when I render video, that fan really spins up and you can hear it. Still, totally worth it for the size.”
Common Praise
- Fits perfectly in cases with very limited CPU cooler clearance (47mm).
- Keeps mid-range CPUs significantly cooler than Intel's stock cooler.
- Easy and quick installation process with included mounting hardware.
- Good value for the cooling performance offered in its size class.
- Effective AGHP heat pipe technology for consistent cooling in any orientation.
Common Complaints
- Fan can be noisy when the CPU is under heavy load, reaching 22.4 dB(A).
- May struggle to maintain peak clock speeds on high-TDP CPUs (e.g., 170W+) without thermal throttling.
- AM5 mounting can be fiddly, potentially requiring minor filing of the motherboard backplate.
- Some users swap the stock fan for a quieter Noctua alternative.
Ownership Tips
- The cooler's performance scales well with lower TDP CPUs, offering quiet operation for daily tasks.
- For sustained heavy workloads on higher-TDP CPUs, expect the fan to run at higher RPMs, increasing audible noise.
- The included thermal paste is adequate for most users, but enthusiasts might see a slight temperature drop with premium paste.
- Check your motherboard's AM5 backplate clearance before installation, as some users reported minor fitment issues.
Frequently Asked Questions
What is the total height of this CPU cooler?

Buying Guide
When looking at CPU coolers, especially low-profile ones like this, the most important thing is height – will it physically fit in your case? This cooler is 47mm tall, which is super short, so it's for those really tiny builds. Also, consider your CPU's heat output (TDP); this one handles up to 125W, so don't expect it to cool a monster CPU without some compromises.
47mm Height
This is the total vertical dimension of the cooler. In small form factor (SFF) cases, every millimeter counts, and 47mm is among the shortest available, crucial for fitting into slim enclosures.
125 watts (TDP)
TDP (Thermal Design Power) indicates the maximum heat a CPU can generate under load that the cooler is designed to dissipate. A 125W rating means it's suitable for most mid-range CPUs, but high-end or overclocked processors will likely exceed this.
92mm TL-9015 Slim PWM Fan
This is the size and type of the fan. A 92mm fan is smaller than standard 120mm or 140mm fans, which means it might need to spin faster (and potentially louder) to move enough air. PWM allows the motherboard to control fan speed based on CPU temperature, balancing noise and cooling.
AGHP technique
This refers to the heat pipe design. It ensures that the heat pipes work efficiently regardless of the cooler's orientation (horizontal or vertical), which is important for varying case layouts in SFF builds.
Alternatives
If this cooler doesn't provide enough cooling for your CPU, look for low-profile coolers with a higher TDP rating and a slightly increased height (e.g., 53mm or 67mm) to accommodate larger heatsinks or fans. If noise is a primary concern, seek coolers with larger fans (e.g., 120mm slim fans) or lower maximum dB(A) ratings.
