Who it fits
Good fit for
You should consider this cooler if you have a mid-tower case with limited CPU cooler height. The 148mm profile ensures it fits where taller models might not. It suits users with mainstream CPUs that do not require massive cooling solutions. The single-tower design saves space on the motherboard. If you want quiet operation with a maximum noise level of 25.6 dB, this unit meets that need. It is ideal for general computing and light multitasking.
Who should skip it
Skip this option if you have a small form factor case with a height limit under 148mm. The 120mm fan size means it will not fit in cases that only support 92mm fans. Users with high-end, power-hungry CPUs might find the single-tower design insufficient for extreme loads. If you need a dual-tower cooler for maximum thermal headroom, look elsewhere. This model is not designed for overclocking heavy processors or extreme thermal environments.
Verdict: This cooler offers a practical balance of height, noise, and cooling for mainstream systems. It fits well in standard mid-tower cases without overwhelming the build.
Key specs explained
Fan Size: 120 mm
This is the standard diameter for the included fan. A 120mm fan fits most cases and radiators. It offers a balance between airflow and noise. You can easily replace it with other standard 120mm fans if needed. This size is common in budget and mid-range air coolers, ensuring broad compatibility with your computer case.
Fan Speed: 1550 RPM
This rating indicates the maximum rotational speed of the fan blades. Higher RPM generally means more air moves across the heatsink. This speed helps dissipate heat from the CPU. It is a moderate speed that avoids excessive noise. You should compare this with other coolers to see if it meets your thermal needs for your specific processor.
Heat Pipes: 4
The cooler uses four copper pipes to transfer heat from the base to the fins. More pipes usually mean better heat spreading. This configuration is standard for single-tower designs. It helps keep the CPU cool under load. When shopping, check if other coolers use more or fewer pipes to gauge their potential thermal performance for your system.
Tower Design: Single-Tower
This design features one block of fins and one fan. It is compact and fits in smaller cases. It is lighter than dual-tower models. This size is ideal for mid-range CPUs that do not generate extreme heat. You should compare this with dual-tower options if you have a high-end processor that requires more cooling surface area.
Cooler Height: 148 mm
This is the total vertical space the cooler occupies. You must check your case specifications to ensure it fits. A 148mm height is common for standard ATX cases. It may not fit in very compact mini-ITX cases. Always measure the clearance inside your case before buying to avoid installation issues with your RAM or side panels.
Build and physical design
According to the listing, this single-tower cooler measures 148mm in height, with a footprint of 120mm by 71mm. You should check your case clearance before buying. The 148mm profile fits medium-sized computer cases but may block tall RAM sticks in tight spaces. The unit weighs 0.645kg, which is light for a metal heatsink. This weight suggests a standard aluminum fin stack rather than a heavy copper block.
The heat dissipation core uses four 6mm pure copper heat pipes. These pipes apply AGHP technology to handle heat transfer regardless of orientation. This helps if you mount the cooler horizontally or vertically. The base is pure copper, which contacts the CPU directly. The rest of the tower is aluminum. This mix keeps the price down while maintaining decent thermal contact.
Controls come via a 4-pin PWM fan. You get 1550 RPM at maximum speed. The fan draws 12V and pushes 66.17 CFM of air. Noise stays at or below 25.6 dBA. You control speed through your motherboard’s fan header. The cooler includes metal fasteners for Intel and AMD sockets. This means you do not need to buy extra mounting hardware for standard platforms like LGA1700 or AM5.
Installation and daily operation
Setting up this cooler involves mounting the unit to your processor socket using the included hardware. The listing specifies metal fasteners for both Intel and AMD platforms. You will need to align the cooler with your specific socket type. Compatible sockets include Intel LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851. AMD support covers AM4 and AM5. Ensure your case has sufficient height clearance, as the tower stands 148mm tall. This dimension is critical for fitting inside medium-sized computer cases without interference. Once mounted, connect the 4-pin PWM fan header to your motherboard. This connection allows the system to control the fan speed automatically. The fan runs at up to 1550 RPM. It delivers 66.17 CFM of airflow while maintaining noise levels at or below 25.6 dB(A). This setup provides efficient cooling with minimal audible disturbance. For lighting, the unit uses ARGB technology. You must connect the ARGB cable to a compatible motherboard header to activate the light effects. The four pure copper heat pipes use AGHP technology to manage heat effectively regardless of orientation. This feature helps maintain performance even if the case is positioned differently. The fan uses S-FDB bearings, which are designed for a long service life of up to 20,000 hours. Daily use remains quiet and stable. The aluminum heat sink and copper base work together to dissipate heat. You benefit from a reliable cooling solution that fits standard form factors. The design prioritizes compatibility and straightforward installation for most users.
Before You Buy This Cooler
You need to verify case clearance before installing this unit. The 148mm height may interfere with tall RAM modules. Check your motherboard manual for socket support. This cooler fits LGA 1700, LGA 1200, AM4, and AM5. You must connect the 4-pin PWM fan header to your motherboard for speed control. The ARGB lighting requires a separate 5V 3-pin header. Ensure your case has enough space for the 120mm fan. This single-tower design suits medium-sized cases. It fits alongside other budget air coolers in our 1 reviews. You should compare its 66.17 CFM airflow against larger dual-tower options if you have a high-TDP CPU. Regularly dust the aluminum fins to maintain performance. The S-FDB bearings promise long service life, but cleaning remains necessary. This option works well for users who prioritize value and standard 120mm compatibility over maximum cooling headroom.
Check before you buy
- Check case clearance for 148mm height and RAM compatibility.
- Verify motherboard supports your CPU socket type.
- Confirm available 4-pin PWM and 5V ARGB headers.
- Ensure your CPU TDP fits single-tower limits.
