Common questions
Which sockets does the Liquid Freezer III Pro 280 support?
Arctic's technical specifications list Intel LGA1851 and LGA1700 plus AMD AM5 and AM4. The shop page's filters also mention 115X and 1200, so confirm with Arctic before planning on an older socket.
How much clearance does it need?
Arctic says the Liquid Freezer needs at least 63 mm of clearance, because of the 38 mm radiator and the fans attached to it.
Is it quiet?
Arctic publishes no dBA figure. Tom's Hardware found the 360 mm Pro loud at full speed and advised capping pump and fan speeds.
