Why Buyers Choose It
- The twin-tower layout and six heat pipes give a clearly defined cooling structure for compatible desktop CPUs.
- The 158mm height is a useful planning detail when checking case clearance.
- The dual PWM fans use a 4 pin, 12V connection and include a Y-type adapter cable, which helps when motherboard fan headers are limited.
- The listed socket support covers several AMD and Intel platforms, so the compatibility check is straightforward.
How It Works
The cooler uses a twin-tower heatsink with six heat pipes and dual fans. The base transfers CPU heat into the heatsink, and the fans move air through the fins to disperse that heat.
For connection, the two fans can be linked with the included Y-type adapter cable. The AM4 fitting note states that the original motherboard backplate is needed for AM4 installation.
What To Know Before You Buy
Check your CPU socket carefully against the listed support before ordering. Confirm that your case has enough clearance for the stated 158mm height, and check that your motherboard has suitable fan header provision for the dual-fan setup.
Pros: The cooler has clearly stated socket support, a 158mm height and an included Y-type adapter cable for the dual fans.
Cons: AM4 installation requires the original backplate, so that fitting detail should be checked before purchase.
