Illustrative image

A 280mm AIO uses two 140mm fans, which move air at lower speeds than 120mm fans. It is a good middle ground between 240mm and 360mm for cases with 140mm mounts.

We compared five 280mm AIOs on pumps, fans, cabling, displays and socket support. This is a research-based comparison built from maker specifications; we did not test these parts ourselves. We limited the list to five because too few other 280mm listings state enough detail to compare.

Our Picks

Best Value 280mm1 of 5

ID-COOLING FX280 PRO SE

The FX280 PRO SE keeps its details simple: a 2900 RPM pump rated at 25dB(A), two 140mm fans at 300 to 1800 RPM and 400mm tubes.

Best for

Budget builds that fit a 280mm radiator.

Skip if

Worth skipping when maximum fan speed of 1800 RPM, behind the H115i RGB (2000 RPM) is a problem.
ID-COOLING FX280 PRO SE

Why we like it

It is the value route to a 280mm radiator. It is rated for 350W, with a 2,900 RPM pump and 400mm sleeved tubes. You also get a 27mm aluminium radiator.

Check that your case offers 280mm 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 Pure Loop 3 280 and every other pick on price at the time of writing. The main gap: maximum fan speed of 1800 RPM, behind the H115i RGB (2000 RPM). If that matters, the H115i RGB offers 2000 RPM.

Best with an LCD2 of 5

NZXT Kraken Plus 280

The Kraken Plus 280 pairs 140mm fans with NZXT's 1.54-inch LCD pump head and zero RPM mode.

Best for

Showcase builds with NZXT CAM.

Skip if

Worth skipping when lighting and display control need NZXT CAM is a problem.
NZXT Kraken Plus 280

Why we like it

It suits builders who want a display without a separate controller. No other pick in this guide offers NZXT CAM software; compare the H115i RGB, which has iCUE software. It also comes with a single breakout cable from the pump cap.

Check that your case offers 280mm 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. It was priced above the H115i RGB and below the Galahad II LCD 280 at the time of writing.

  • NZXT's Turbine pump

Cons

Solid Alternative3 of 5

CORSAIR iCUE LINK H115i RGB

The H115i RGB runs pump and fans through Corsair's iCUE LINK hub, with fans up to 2000 RPM and zero RPM mode.

Best for

Buyers who want zero rpm mode stops the fans at light load.

Skip if

Look at the others if this bothers you: lighting and display control need iCUE.
CORSAIR iCUE LINK H115i RGB

Why we like it

It belongs in Corsair-based builds. No other pick in this guide offers iCUE software; compare the Kraken Plus 280, which has NZXT CAM software. Check that your case offers 280mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks.

The maker doesn't spell out LGA1851 mounting, so confirm it on the maker's site for a Core Ultra build. Plan to install iCUE for lighting control; fan and pump speed can also run from the motherboard's headers. It was priced above the Pure Loop 3 280 and below the Kraken Plus 280 at the time of writing. There is no published pump speed figure, whereas the Galahad II LCD 280 offers 3600 RPM.

Largest Display4 of 5

LIAN LI Galahad II LCD 280

The Galahad II LCD 280 has the largest screen here, a 2.88-inch IPS panel, on an Asetek pump rated up to 3600 RPM.

Best for

Builds centred on the pump-head screen.

Skip if

Skip it if this is a deal-breaker for you: lighting and display control need L-Connect.
LIAN LI Galahad II LCD 280

Why we like it

Its fans use wireless lighting and speed control. It is the only pick here with L-Connect software; the Kraken Plus 280 has NZXT CAM software instead. Check that your case offers 280mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks.

The maker doesn't spell out LGA1851 mounting, so confirm it on the maker's site for a Core Ultra build. Plan to install L-Connect for lighting and display control; fan and pump speed can also run from the motherboard's headers. At our last price check it topped the group, with the Kraken Plus 280 the nearest cheaper option.

Quiet-Focused Pick5 of 5

be quiet! Pure Loop 3 280mm

The Pure Loop 3 280 is be quiet!'s low-noise take, with Pure Wings 3 fans that daisy-chain and a PWM pump.

Best for

Quiet builds without RGB software.

Skip if

Price-first buyers should look at the FX280 PRO SE, which cost less when we checked.
be quiet! Pure Loop 3 280mm

Why we like it

It suits quiet builds that skip RGB software. Its PWM pump has a six-pole motor for low vibration, and flexible sleeved tubes make mounting simple. Check that your case offers 280mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks.

The maker doesn't spell out LGA1851 mounting, so confirm it on the maker's site for a Core Ultra build. Before buying, weigh one limit: costs more than the FX280 PRO SE at the time of writing. Its price falls between the FX280 PRO SE and the H115i RGB, based on our last check.

How We Chose These 280mm AIO Coolers

What to Look for in a 280mm AIO Cooler

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

  1. Maximum fan speed

    The H115i RGB tops maximum fan speed at 2000 RPM and the FX280 PRO SE sits lowest at 1800 RPM. The H115i RGB is the pick for maximum fan speed. The Kraken Plus 280, the Galahad II LCD 280 and the Pure Loop 3 280 give no maximum fan speed figure, so 2 of 5 picks are compared here.

  2. How much pump speed you need

    Across these 2 picks pump speed spans 2900 RPM (the FX280 PRO SE) to 3600 RPM (the Galahad II LCD 280). If pump speed is your first filter, the Galahad II LCD 280 sets the ceiling at 3600 RPM. The Kraken Plus 280, the H115i RGB and the Pure Loop 3 280 give no pump speed figure, so 2 of 5 picks are compared here.

  3. Zero RPM mode

    The Kraken Plus 280 and the H115i RGB have it. Sort out zero RPM mode before price: it splits 2 stated picks into groups of 2.

  4. Software

    The Kraken Plus 280 lists NZXT CAM; the H115i RGB lists iCUE; the Galahad II LCD 280 lists L-Connect. Settling software first narrows 3 picks to 1 or 1 or 1.
