What to know before buying

Listing details to confirm

Listing details are inconsistent: the title says dual 120 mm fans at 1850 rpm, while one feature describes 1500 rpm, and the fan speed is listed as both 1850 RPM and 1850RPM. The stated noise is 29.5 Decibels in details and ≤29.5dBA in features. Package contents list “CPU Air Cooler, CPU Fan, Close” and do not clarify whether both fans, the display board, or the claimed kit accessories are included. Confirm the selected listing and socket-specific mounting requirements before purchase. The AMD installation note says the motherboard backplate is not included and the original backplate must be retained.

Frequently asked questions

Which CPU sockets are listed as compatible?

The listing names AMD AM4 and AM5, and Intel LGA1851, 1700, 1150, 1151, 1155, 1156 and 1200. Check the exact socket and mounting requirements for your motherboard.

What is specified about the fans?

The title describes two 120 mm PWM fans and 1850 rpm. A feature also mentions 1500 rpm, so the stated operating speed is inconsistent. The listed fan dimensions are 120x120x28mm.

Does the cooler include a display board?

The title calls out a digital display board top cover and a feature gives its motherboard 9-pin interface, but the explicit contents list does not identify the board. Confirm it is included and compatible with your motherboard.

Is an AMD motherboard backplate included?

The listing says the original AMD motherboard backplate must remain installed and is not included.
