Why Buyers Choose It
- The 37mm height suits very compact cases where larger coolers will not fit.
- The stated RAM and PCIe compatibility is useful when clearance is tight on AM4 systems.
- The included thermal paste and mounting system give you the parts needed for installation.
- The black finish matches builds where a darker appearance is preferred.
How It Works
The fan uses PWM automatic speed control, so its speed is managed by the system rather than adjusted manually. The included Low-Noise Adaptor is provided for quieter operation, and the cooler is mounted with the SecuFirm2 system.
The package also includes NT-H1 thermal paste, so that key installation item is already supplied.
What To Know Before You Buy
Check that your motherboard and case are suitable for an AMD AM4 low-profile cooler before ordering. The stated 37mm height is important if your build has limited clearance, and the tailored footprint is especially relevant if RAM or PCIe space is tight.
The product is described for AMD Ryzen CPUs and APUs with moderate heat load, so compare that intended use with your own processor choice. Review the selected variation carefully, as the finish is chromax.black.
