How It Works
The cooler uses an NF-A12x25r 120mm fan with PWM for automatic speed control. Under load it is described as delivering full cooling performance, while at idle it is described as whisper quiet.
The included SecuFirm2 mounting system and offset mounting option are part of the installation setup, with support listed for Intel LGA1851, LGA1700, LGA1200, LGA115x and AMD AM5 & AM4.
Real World Use
This cooler is positioned as a low-height option for systems where case compatibility matters, especially when fitting into most 4U rackmount server cases. The listed RAM compatibility also makes it easier to plan around memory clearance on the supported sockets.
What To Know Before You Buy
Check your case clearance against the stated 145mm height before ordering. Confirm that your motherboard uses one of the listed Intel or AMD sockets, and review the RAM layout if you want to make use of the stated compatibility.
The cooler is brown and supplied with NT-H1 thermal paste, the SecuFirm2 mounting system and Low-Noise Adaptors, so it is worth checking that these included items match your installation needs.
