It is a practical choice for users who need low profile cooling without sacrificing too much airflow.
What stands out
- 47mm total height fits in small ITX cases
- Four 6mm heat pipes with AGHP technique
- 92mm PWM fan with 2700 RPM max speed
- Supports AM4, AM5, LGA1700, and older sockets
- Aluminum heatsink with included thermal paste
Who it fits
Good fit for
You should buy this if you are building an HTPC or an ITX system where space is limited. The 47mm height ensures it clears most low-profile cases. The broad socket support makes it versatile for both Intel and AMD platforms. If you need quiet operation, the PWM fan adjusts speed based on temperature. This cooler is ideal for users who want reliable cooling in a small package without worrying about RAM clearance.
Who should skip it
Skip this if you need extreme cooling performance for high-end overclocking. The 47mm height and single fan limit its heat dissipation capacity. You should look elsewhere if you require taller coolers for better airflow. This model is not suitable for large mid-tower or full-tower cases where height is not a constraint. If you need more than 42.58 CFM of airflow, this low-profile design will not meet your thermal demands.
Verdict: This low-profile cooler is a solid choice for compact builds where space is the primary constraint. It offers decent cooling performance for its size, provided you do not expect top-tier thermal results.
Key specs explained for this cooler
Cooler Height: 47 mm
This is the total vertical space the cooler occupies. You need this measurement to ensure the unit fits inside your case without hitting the side panel or RAM sticks. A 47mm height is very low, making it ideal for ITX builds or HTPCs where space is tight. It is significantly shorter than standard tower coolers, which often exceed 150mm.
Fan Size: 92 mm
This is the diameter of the fan attached to the heatsink. Smaller fans like this 92mm model spin faster to move air through the dense fins. They can be louder than larger fans at high speeds. You should check the noise level if you plan to keep the system quiet. This size allows the cooler to remain compact while maintaining airflow.
Fan Speed: 2700 RPM
This is the maximum rotational speed of the fan blades. Higher RPM means more air is pushed through the cooler, improving heat dissipation. However, it also increases noise. You can adjust this speed via PWM if your motherboard supports it. Compare this to larger coolers that might spin slower but move more air due to fan size.
Heat Pipes: 4
This is the number of copper tubes inside the cooler that transfer heat from the CPU to the fins. Four pipes provide a good balance for mid-range CPUs. More pipes generally mean better heat spreading. The AGHP technique mentioned in the listing helps these pipes work efficiently in vertical orientations. This count is standard for low-profile designs.
Design and Build Details
The listing describes the heatsink as an aluminum tower with a black finish. It measures 94.5 by 95 by 47 mm. This compact footprint allows it to fit into tight spaces. The low profile design ensures it clears low-profile RAM sticks. You can mount this cooler on Intel LGA1700, LGA1200, LGA1150, LGA1151, and AMD AM4 or AM5 sockets. Metal mounting fasteners are included for each platform. The package also contains thermal paste for immediate installation.
Four 6mm heat pipes use AGHP technology. This process involves secondary welding to prevent the inverse gravity effect. You get consistent cooling regardless of whether the cooler is mounted vertically or horizontally. The fins are welded to the heat pipes to improve heat transfer efficiency. The unit is paired with a TL-9015B 92mm PWM fan. This fan operates at up to 2700 RPM. It delivers 42.58 CFM of airflow and 1.33 mmH2O of static pressure.
The fan connects via a 4-pin PWM header. This allows your motherboard to adjust speed automatically. Noise levels are listed at 22.4 dB(A) at maximum speed. The combination of aluminum fins and copper heat pipes provides a balanced thermal solution. The black anodized finish helps it blend with modern ITX builds. The design prioritizes space efficiency without sacrificing basic cooling capabilities. You get a reliable low-profile solution for small form factor PCs.
Setup and Everyday Use Guide
Installation relies on the included metal mounting fasteners for your specific platform. The listing confirms support for Intel sockets LGA 1700, 1150, 1151, 1155, 1156, and 1200, as well as AMD AM4 and AM5. You must match the hardware to your motherboard socket. The manufacturer provides a manual or video to guide the physical attachment. This ensures the cooler sits flat against the CPU surface for proper heat transfer. The unit arrives with attached thermal paste to simplify the initial setup. You do not need to buy separate paste for basic operation.
Daily use centers on the 92mm TL-9015B PWM fan. This fan connects via a 4-pin header, allowing your motherboard to control speed automatically. The maximum speed reaches 2700 RPM, which delivers up to 42.58 CFM of airflow. This automatic control helps balance cooling performance with noise levels. The listing notes a maximum noise output of 22.4 dB, suggesting quiet operation during light tasks. The AGHP technique in the four 6mm heat pipes helps maintain consistent cooling regardless of whether your case is oriented vertically or horizontally. This feature prevents gravity from reducing efficiency. The aluminum radiator material conducts heat away from the processor efficiently. You can expect stable temperatures in ITX or HTPC builds without worrying about RAM clearance, given the low profile design. The system is designed to run unattended once installed.
Before You Buy This Cooler
This 47mm low-profile air cooler fits ITX and HTPC cases where space is tight. You must verify that your RAM does not interfere with the 94.5 by 95 mm heatsink base. Although the listing includes thermal paste, you might want to buy a higher-grade compound for better heat transfer. The cooler supports Intel LGA 1700, 1150, 1151, 1155, 1156, 1200, and AMD AM4 and AM5 sockets. Ensure your case provides at least 47mm of vertical clearance. The included 92mm PWM fan helps keep noise low, but you should check your case fan headers to ensure it connects properly. This unit is ideal if you prioritize size over raw cooling power. It sits alongside larger air coolers in our guide, offering a specialized solution for compact builds rather than high-TDP gaming rigs. Regularly dust the aluminum fins to maintain airflow efficiency.
Check before you buy
- Verify RAM clearance against the 95mm heatsink width.
- Confirm case supports 47mm total cooler height.
- Check socket compatibility for your specific CPU.
- Ensure motherboard has a 4-pin PWM header.
