Our Picks

Best Cooling Under $3001 of 6

ARCTIC Liquid Freezer III Pro 420 A-RGB

The Liquid Freezer III Pro 420 uses three 140mm fans on a larger radiator.

Best for

Performance-first builds.

Skip if

Look at the other picks if you need a feature not covered above.
ARCTIC Liquid Freezer III Pro 420 A-RGB

Why we like it

Check that your case offers 420mm radiator support. Its 420mm radiator uses 140mm P14 PRO fans, and an integrated VRM fan cools the power stage. A contact frame for LGA1851 and LGA1700 is included.

It also offers native offset mounting. Check that your case offers 420mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks. It supports both AM5 and Intel LGA1851.

Another plus: fan cables routed inside the tube sleeving. It cost the least of the 6 picks at the time of writing, with the Peerless Vision 360 the next step up.

Look at the others if this bothers you: lighting and display control need NZXT CAM.
NZXT Kraken Elite 360 RGB White

Why we like it

You pay mainly for the screen. No other pick in this guide offers a 2.72-inch IPS pump display; compare the Peerless Vision 360, which has a 3.95-inch pump display. No other pick in this guide offers NZXT CAM software; compare the Titan II 360 RX White, which has iCUE software.

You also get a 640x640 LCD with a 60Hz refresh rate and a white finish. Check that your case offers 360mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks. It supports both AM5 and Intel LGA1851.

Plan to install NZXT CAM for lighting and display control; fan and pump speed can also run from the motherboard's headers. Only the Galahad II LCD 360 came close to it on price at the time of writing; it cost the most of the 6 picks.
