How It Works
The cooler uses two NF-A12x25 PWM fans with automatic speed control. The package includes SecuFirm2 mounting and NT-H1 thermal paste, and the mounting system is listed for Intel LGA1851, LGA1700, LGA1200, LGA115x and AMD AM5 and AM4. An offset mounting option is also mentioned for best efficiency.
Real World Use
In practical use, the 158mm height means the cooler should be checked against the available space in the case. The compatibility notes also point buyers to confirm RAM, PCIe and motherboard fit before ordering, especially where space around the socket matters.
What To Know Before You Buy
Check your case clearance, since the cooler is 158mm high. Confirm the selected mounting platform, because the included SecuFirm2 system is listed for specific Intel and AMD sockets. The RAM and PCIe clearance notes are useful if your board has tight spacing around the CPU area.
Pros: Dual PWM fans, included thermal paste and broad socket support are all clearly stated.
Cons: The 158mm height means case fit needs checking before ordering.
