What to know before buying

Listing details to confirm

The title and compatibility feature give a broader socket list than the abbreviated technical description, while fan speed, noise and airflow are stated with different precision in different sections. Confirm exact socket support and the applicable fan specifications for the selected listing. The stated 156 mm cooler height should also be compared with case clearance, and the ARGB connection requires a compatible 5V 3-pin header for motherboard synchronisation.

Who is it for?

A good fit for

Desktop builders seeking a tower air cooler with a 120 mm PWM fan and ARGB lighting.
Buyers whose CPU socket is among the listed Intel LGA or AMD AM4/AM5 platforms.

Less suited to

Builds without room for a cooler listed at 156 mm tall.
Systems without a compatible 5V 3-pin header if motherboard-synchronised ARGB is required.

Frequently asked questions

Which CPU sockets are listed as compatible?

The feature listing names Intel LGA 1150, 1151, 1155, 1156, 1200, 1700 and 1851, plus AMD AM4 and AM5. Another technical description abbreviates the supported platforms, so check the exact socket and mounting hardware for the listing you select.

How tall is the cooler?

The stated heatsink height is 156 mm. Compare that figure with the CPU-cooler clearance specified for your case.

What connections do the fan and lighting use?

The fan uses a 4-pin PWM power connection, while the ARGB lighting is listed as 5V 3-pin. The lighting synchronisation claim depends on a compatible motherboard header.
