What to know before buying

Listing details to confirm

The listing gives fan speed as 2000RPM + 10% in the detailed specifications, while another field says maximum rotational speed is 2000 RPM. Its airflow is listed as 70.84CF. M 9.8 dB(A) in one feature description but 70.84 Cubic Feet Per Minute and 29.8 Decibels in separate detail fields. Treat the fan figures as inconsistent rather than settled. For AMD installation, the listing says to use the motherboard's original backplate. Check cooler height and memory clearance against your case and components.
