## Before you buy

- The listing gives two fan sizes and separate operating figures, but also shows a single 1850 RPM and 29.5 dB specification without tying those figures to a fan. Treat the individual fan figures as listing claims, not verified measurements. Confirm socket support, case clearance and memory fit for your build. AMD installation is stated to require the original motherboard backplane.

## In the box

- CPU cooler (Included)

## A good fit for

- Desktop builders who want a dual-tower air cooler and have space for the listed 140 x 160 x 158 mm dimensions.
- Buyers using a listed AM4, AM5 or Intel LGA socket who can confirm fit with their motherboard and case.

## Less suited to

- Builds where the case cannot accommodate the listed cooler dimensions or clearance is uncertain.

## Customer feedback

Only aggregate rating information is available, based on a single rating, so it offers very limited evidence about how buyers experience the cooler. It cannot establish consistent cooling, noise or installation results. Use the listed dimensions, socket support and fan specifications to assess fit and suitability instead.

## Frequently asked questions

### Which processor sockets are listed as compatible?
The listing names AMD AM4 and AM5, plus Intel LGA 1851, 1700, 1150, 1151, 1155, 1156 and 1200. Confirm your exact motherboard and installation requirements before purchase.
### How large is the cooler?
The stated size with fans is 140 x 160 x 158 mm. Check your case and nearby component clearances against those dimensions.
### What fans does it use?
The listing specifies one 120 mm fan and one 140 mm fan with 4-pin PWM connections. It gives separate speed, airflow and noise figures for each.
