Who it fits
Good fit for
You should consider this cooler if you build in an ITX case with limited CPU clearance. The 45mm height ensures it fits where taller towers cannot. It suits users with CPUs up to 150W TDP who need reliable cooling in a small footprint. The wide socket support makes it a good choice for both AMD AM5/AM4 and Intel LGA1700/1200 builds. If you prioritize case compatibility and decent thermal performance in a compact package, this option fits your needs.
Who should skip it
You should skip this cooler if you plan to use a high-end CPU exceeding 150W TDP. The low-profile design limits airflow compared to larger towers. Users who need maximum cooling headroom for overclocking will likely find this insufficient. If your case allows for standard-height coolers, you may get better performance from a larger unit. Additionally, if you require RGB lighting or advanced software control, this basic fan-driven unit does not offer those features.
Verdict: This cooler offers a practical balance of size and cooling power for small builds. It is a solid choice for ITX systems with moderate thermal demands.
Key specs explained
Cooler Height: 45mm
This measurement defines the maximum vertical space the cooler occupies above the CPU. You need this clearance to fit the unit inside your case. It is ideal for ITX builds where standard towers are too tall. Check your case specifications before buying to ensure there is enough room for RAM and the cooler itself.
Fan Size: 120mm
The fan measures 120 millimeters across, which is larger than typical slim fans. Larger fans move more air at lower speeds. This results in quieter operation compared to smaller fans spinning faster. You benefit from reduced noise while maintaining adequate airflow for heat dissipation in compact enclosures.
Heat Pipes: 6
Six copper pipes transfer heat from the base to the fins. More pipes generally mean better heat spreading and faster cooling. This configuration helps manage thermal loads efficiently. You get improved performance compared to coolers with fewer pipes, making it suitable for moderate to high-end processors.
TDP Rating: 150W
The cooler is rated to handle processors with a Thermal Design Power up to 150 watts. This indicates its maximum heat removal capacity. You can use it with powerful CPUs, provided your case has good airflow. Compare this rating with your CPU specifications to ensure adequate cooling for your specific chip.
Design and build details
According to the listing, this unit uses six copper heat pipes. These pipes transfer heat from the base to the aluminum fins. This layout helps move thermal energy away from the processor quickly. The cooler is rated for up to 150W TDP. This means it handles moderate to high power draws. You should match this to your CPU's needs. Overpowering a low-TDP chip is unnecessary. Undersizing a high-TDP chip causes throttling.
The tower design is low profile. The total height is 45mm. This compact size fits into ITX cases. Standard towers often block RAM or exceed case limits. This height avoids those conflicts. You can install this in tight spaces. Check your case clearance before buying.
It includes a 120x120x15mm PWM fan. The fan size allows good airflow. The slim 15mm thickness keeps the profile low. PWM support lets you control speed. This helps balance noise and cooling. The listing notes low-noise operation. This makes it suitable for quiet builds. The cooler supports AM5, AM4, LGA1700, 1200, 1150, and 2011 sockets. This wide compatibility covers most modern platforms. You do not need to check specific bracket availability for these common mounts.
Installation and daily operation
Setting up this cooler involves ensuring your case has at least 45mm of vertical clearance. The compact design allows it to fit into most ITX chassis without blocking adjacent RAM slots or PCIe slots. You will need to verify that your motherboard socket matches one of the supported options. The listing confirms compatibility with AMD AM5 and AM4 platforms. It also supports Intel LGA1700, 1200, 1150, and 2011 sockets. This wide range means you can use it across various recent and older generations of processors. The installation process follows standard mounting procedures for low-profile units. You attach the base to the CPU and secure the fan to the heatsink. The 120mm PWM fan connects to the motherboard header. This allows the system to adjust fan speed based on temperature. Daily use relies on the six heat pipes to transfer heat from the processor to the fins. The 150W TDP rating suggests the cooler can handle moderate to high power loads. However, actual performance depends on your specific CPU and case airflow. The 120x120x15mm fan size helps distribute air evenly across the fin stack. This design aims to keep noise levels low during light tasks. Under heavy loads, the fan will spin faster to maintain temperatures. You should monitor your CPU temperatures to ensure the 150W rating is sufficient for your workload. If you run intensive applications, verify that your case provides adequate intake and exhaust airflow. The low-profile form factor does not change how you manage thermal paste or cable routing. You simply need to ensure the fan does not obstruct other components in your tight build space.
Before you buy this cooler
This LDPCSJ unit targets small form factor builds. You must verify your case supports a 45mm height limit. Standard ATX towers will not fit. The cooler lists compatibility with AM5, AM4, LGA1700, 1200, 1150, and 2011 sockets. Confirm your specific motherboard mounting holes match the included brackets. The listing mentions a 120mm PWM fan. Ensure your case has space for a 120x120x15mm fan at the rear or top. You should also check if the six heat pipes interfere with tall RAM modules. This option suits users who prioritize compactness over raw cooling power. It fits alongside larger air coolers as a specialized choice for ITX cases. Keep the fan clean to maintain performance. Dust accumulation on the fins can reduce efficiency over time. Regular maintenance ensures the six heat pipes continue transferring heat effectively. This cooler is a practical solution for tight spaces, not high-end overclocking.
Check before you buy
- Verify your case supports 45mm cooler height.
- Confirm socket compatibility for your CPU.
- Check clearance for the 120mm fan.
- Ensure RAM does not block heat pipes.

What is the maximum height clearance required?
You need a case that allows at least 45mm of vertical space above the CPU socket. This height restriction is the defining feature of this low-profile design. If your case has less than 45mm of clearance, this unit will not fit physically inside the chassis.
How many heat pipes does it use?
The cooler features six heat pipes. These pipes transfer heat from the base to the aluminum fins to dissipate thermal energy. This configuration helps move heat away from the processor efficiently within the constraints of a small form factor design.
Is it suitable for high-end AMD processors?
It is best for moderate thermal loads on AMD AM5 and AM4 processors. While it supports these sockets, it is designed for compact ITX builds rather than extreme overclocking. High-end chips generating significant heat may exceed its cooling capacity.
Does it include a fan?
Yes, the product attributes list a fan as a included feature. This fan works with the heat pipes and fins to push air through the cooler. You must ensure your motherboard has a header to connect this fan for proper operation.
Will it block nearby RAM slots?
Its compact 45mm profile is designed to avoid blocking adjacent components. This allows it to fit into most ITX chassis without interfering with RAM slots or PCIe slots. Always verify your specific motherboard layout to ensure adequate space for memory modules.
