Why Buyers Choose It

  • The stated 135mm height gives a clear clearance check before installation in a compact case.
  • The 6 heat pipes and double tower layout are useful specifications for buyers comparing air cooler designs.
  • The PWM fan is a practical detail for anyone wanting a cooler with temperature-based fan control.
  • The listed Intel and AMD socket support makes it easier to match the cooler to a specific platform.

How It Works

The cooler uses a mounting kit for the supported CPU sockets, and the fit should be checked against the selected platform before installation. The fan is described as PWM controlled, so its speed is intended to respond to temperature control rather than remaining fixed.

The description also mentions shock-absorbing silicone feet, anti-touch fan blade design, and S-FDB bearing. These are listed features of the fan assembly and cooler design.

Real World Use

In use, the main checks are case height and socket compatibility. The stated 135mm height means it is worth checking internal space before ordering, especially where cooler clearance is limited. The 125 x 110 x 135 mm size is also useful when comparing the cooler with nearby motherboard or case components.

What To Know Before You Buy

Confirm that your motherboard socket matches one of the listed Intel or AMD platforms before ordering. Check that your case has room for a cooler with a stated height of 135mm and overall size of 125 x 110 x 135 mm. If you are comparing coolers, the 6 heat pipes, double tower layout and 120mm PWM fan are the main verified features to review.
