## At a glance

- Four 6 mm heat pipes use the listing's AGHP design, which is described as intended to reduce orientation effects.
- The included TL-C12C fan has PWM control and a four-pin connector.
- The listing names AMD AM4 and AM5 plus a range of Intel sockets, including LGA 1851 and 1700.
- The stated 148 mm height makes case CPU-cooler clearance an important fit check.

## Pros

- Broad listed socket compatibility can make the cooler suitable for upgrades across supported AMD and Intel platforms.
- A 120 mm PWM fan and four heat pipes provide an air-cooling setup without a liquid-cooling loop.

## Before you buy

- The product description lists 125\(L\)x71\(W\)x148\(H\)mm and 0.645kg, while the details list dimensions of 4.72"L x 2.8"W x 5.83"H and weight of 644 g. Fan speed, airflow and noise are also given with maximum or tolerance notation in the feature text but without it in details. Confirm the exact revision and listing specifications before purchase. The explicit contents list names only a CPU cooler, while other listing text mentions thermal paste and mounting parts, so confirm what is included. Check case clearance and the exact socket mounting hardware for your build.

## In the box

- CPU cooler (Included)
- Thermal paste (Check selected pack): Mentioned in product description but absent from the explicit contents list. Check the selected listing.
- Mounting hardware (Check selected pack): Mounting parts are described, but the explicit contents list names only a CPU cooler. Confirm the selected package.

## A good fit for

- Desktop builders needing an air cooler for one of the listed AMD AM4/AM5 or Intel sockets.
- Buyers replacing a stock cooler in a case with at least the stated 148 mm cooler clearance.
- Users prioritizing an air-cooling configuration with a PWM fan and four heat pipes.

## Less suited to

- Builders whose case has less than 148 mm of CPU-cooler clearance.
- Anyone needing confirmed compatibility with a socket or an explicit package bundle not listed here.

## Customer feedback

Customer feedback describes lower temperatures and good performance, including with 65 W CPUs, and reports quiet operation under normal loads. Some customers find installation straightforward, while opinions about the mounting system are mixed. For a cooler whose listing specifies four heat pipes and a 120 mm PWM fan, these reports may be relevant to everyday desktop builds, but they do not establish results for every CPU, case or workload.
- Positive themes: Customers report effective cooling, quiet operation under normal loads, and straightforward installation.
- Mixed feedback: Feedback on the mounting system is mixed, with some finding it user-friendly and others describing installation as difficult.

## Frequently asked questions

### Which CPU sockets are listed as compatible?
The listing names AMD AM4 and AM5, and Intel 1150, 1151, 1155, 1156, 1200, 1700, 17XX and 1851. Confirm that the selected unit includes the correct mounting parts for your board.
### Will it fit in my PC case?
The product is listed at 148 mm high. Compare that with your case's CPU-cooler clearance before buying.
### What fan does it use?
The listing specifies a TL-C12C 120 mm PWM fan with a four-pin power connector. Listed fan figures include 1550rpm±10%, 66.17CFM\(MAX\) airflow and ≤25.6dB\(A\) noise.
### Is thermal paste included?
One product description says thermal paste is included, but the explicit contents list names only a CPU cooler. Check the selected listing's package contents before relying on the paste being included.
