AIO Liquid Coolers in Lebanon.

Choosing a radiator size

• 120 mm: for small cases with a single fan mount, and for moderate processors.
• 240 and 280 mm: a strong match for most gaming builds with six- and eight-core CPUs.
• 360 mm: the most popular size for Ryzen 9, Core i9 and Core Ultra 9, and for quiet running under load.
• 420 mm: maximum cooling for large cases, using three 140 mm fans, such as the Arctic Liquid Freezer III 420 and Thermaltake TH420.

Bigger radiators cool more but need space. Check your PC case listing for the radiator sizes it supports at the top, front and side.

Where to mount the radiator

Top-mounted radiators exhaust warm air out of the case and keep the pump below the radiator, which is the usual choice. A front-mounted radiator takes in cool air, but it reduces the room left for the graphics card, so the builder subtracts the radiator's thickness from the case's GPU clearance.

Screens, lighting and wireless fans

Pump-head displays show temperatures, images or animations: the NZXT Kraken range, Lian Li Galahad II LCD and HydroShift II LCD and OLED models, and Thermalright Frozen Warframe, Levita Vision, Trofeo Vision and Wonder Vision coolers. Lian Li's TL and SL-INF versions use daisy-chained or wireless UNI FANs to cut cables. Fanless HydroShift II versions let you fit your own fans.

Socket support and installation

Every AIO here supports AM5 and AM4, and most support LGA1851 and LGA1700 too; some also list LGA1200, LGA115x, LGA2066 or Threadripper. The pump connects to the motherboard's pump or fan header, and the builder flags when a build has more fans and pumps than headers. For a custom loop, Thermaltake Pacific water cooling kits are also listed.

Looking after an AIO

An AIO needs very little care: keep the radiator fins free of dust, make sure the pump is connected to a powered header, and keep the radiator's top above the pump so air in the loop collects away from it. If temperatures rise over time, cleaning the radiator and fans is the first step.
