The strongest coolers pair a 360mm or 420mm radiator with extras such as a VRM fan or a pump display. Every pick has one of those, ordered by radiator size.

This is a research roundup, not a lab test: fan size, pump display and VRM fan come from each maker's published specs; nothing here was tested in-house, and a missing pump display is flagged, not filled in.

Our Picks

Also Consider1 of 5

ARCTIC Liquid Freezer III Pro 420 A-RGB

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

Best for

Buyers who want P14 PRO fans.

Skip if

If budget leads, the Liquid Freezer III Pro 360 was cheaper at our last price check.
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.

You also get 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.

Worth noting: fan cables routed inside the tube sleeving. It was priced above the Liquid Freezer III Pro 360 A-RGB and below the Peerless Vision 360 at the time of writing.

Lowest Price Here2 of 5

ARCTIC Liquid Freezer III Pro 360

The Liquid Freezer III Pro 360 is built around cooling rather than lighting: offset mounting over the CPU hotspot, a contact frame for Intel and a small fan for the board's power stages.

Best for

Buyers who would rather put the savings elsewhere than into the Liquid Freezer III Pro 360 A-RGB.

Skip if

Look at the other picks if you need a feature not covered above.
ARCTIC Liquid Freezer III Pro 360

Why we like it

Its fan cables run inside the tube sleeve for a tidy build. Its integrated VRM fan cools the motherboard power stage, which a standard AIO leaves without airflow. The offset cold plate sits over the CPU hotspot rather than the centre of the heatspreader.

The fan cables run inside the tube sleeving, so only one cable reaches the motherboard. 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. It undercut the Liquid Freezer III Pro 360 A-RGB and every other pick on price at the time of writing.

Strong Alternative3 of 5

ARCTIC Liquid Freezer III Pro 360 A-RGB

The Liquid Freezer III Pro 360 A-RGB is the lit version of ARCTIC's thick-radiator 360, with the same VRM fan and offset mounting.

Best for

Buyers who want P12 PRO A-RGB fans.

Skip if

Price-first buyers should look at the Liquid Freezer III Pro 360, which cost less when we checked.
ARCTIC Liquid Freezer III Pro 360 A-RGB

Why we like it

An integrated VRM fan cools the motherboard power stage, and the offset cold plate targets the CPU hotspot. The A-RGB P12 PRO fans add lighting without losing airflow. The contact frame spreads pressure evenly on Intel LGA1851 and LGA1700 chips.

Its fan cables run inside the tube sleeve, so only one cable reaches the motherboard. The P12 PRO fans spin faster than the standard P12 when needed. The VRM fan is PWM-controlled, and the contact frame is aimed at longer CPU life on Intel LGA1851 and LGA1700.

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.

Worth a Look4 of 5

Thermalright Peerless Vision 360 ARGB

The Peerless Vision 360 has a 3.95-inch magnetic screen at a lower price than most screen AIOs.

Best for

Buyers who want magnetic screen with a 60Hz refresh rate.

Skip if

Price-first buyers should look at the Liquid Freezer III Pro 360, which cost less when we checked.
Thermalright Peerless Vision 360 ARGB

Why we like it

A 3.95-inch magnetic screen sits on the pump head, and three TL-M12Q fans splice together to reduce cables. The fans have infinity-mirror lighting. The 480x480 screen can show system stats or custom images.

It also offers a magnetic screen with a 60Hz refresh rate. 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. On price it sat fourth of 5, between the cheaper Liquid Freezer III Pro 420 and the pricier Kraken Plus 360 RGB White, at the time of writing.

Premium Pick5 of 5

NZXT Kraken Plus 360 RGB White

Best for

Buyers for whom price is not the deciding factor, since the Liquid Freezer III Pro 360 costs less.

Skip if

Worth skipping when lighting and display control need NZXT CAM is a problem.
NZXT Kraken Plus 360 RGB White

Why we like it

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.

You also get this: 1.54-inch pump-head display for temperatures or images. It makes the most sense for buyers for whom price is not the deciding factor, since the Liquid Freezer III Pro 360 costs less, since it offers a white finish with RGB fans at the highest price in the group. It was the most expensive pick when we checked, so weigh what it adds over the Peerless Vision 360.

What to Look for in a High-Performance CPU Cooler

Key buying criteria so you get the right fit the first time.

  1. VRM fan

    The Liquid Freezer III Pro 420, the Liquid Freezer III Pro 360 and the Liquid Freezer III Pro 360 A-RGB have it. Sort out VRM fan before price: it splits 3 stated picks into groups of 3.

  2. Features beyond the spec table

    The Liquid Freezer III Pro 360: native offset mounting toward the CPU hotspot. The Peerless Vision 360: splice-connected fans. The Kraken Plus 360 RGB White: NZXT's Turbine pump.

  3. Budget

    $50 to $100 buys the Liquid Freezer III Pro 360, the Liquid Freezer III Pro 360 A-RGB, the Liquid Freezer III Pro 420 and the Peerless Vision 360; $100 to $150 buys the Kraken Plus 360 RGB White at our last check.

  4. Match the pick to your priority

    Buyers who would rather put the savings elsewhere than into the Liquid Freezer III Pro 360 A-RGB: the Liquid Freezer III Pro 360. Buyers for whom price is not the deciding factor, since the Liquid Freezer III Pro 360 costs less: the Kraken Plus 360 RGB White.

  5. Mount the pump below the radiator's top

    Air collects at the highest point of the loop. Keep the radiator's top edge above the pump, or tubes-down at the front, to avoid pump noise and wear.
