  6. FAQ

A higher maximum fan speed gives headroom for sustained loads, at the cost of noise when it's used. Every pick has fans rated at 1,800 RPM or more, ordered by maximum speed.

The order reflects max fan speed, max pump speed and fan size from maker specifications; a missing max pump speed is flagged, not filled in rather than guess, since we have not benched them.

Highest Maximum Fan Speed1 of 5

CORSAIR iCUE LINK H100i RGB

The H100i RGB lists the fastest fans here at 2400 RPM, with zero RPM mode for idle.

Best for

Buyers who put maximum fan speed first.

Skip if

Look at the others if this bothers you: lighting and display control need iCUE.
Check price on Amazon for CORSAIR iCUE LINK H100i RGB (opens in a new tab)
CORSAIR iCUE LINK H100i RGB

Why we like it

It runs through Corsair's iCUE LINK hub. On maximum fan speed it leads this guide at 2400 RPM, ahead of the HydroShift II LCD-S 360 (2200 RPM). It shares iCUE software with the Titan 360 RX; the HydroShift II LCD-S 360 goes with L-Connect software.

It also comes with a 20-LED pump cap. Check that your case offers 240mm 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. Its price falls between the Titan 360 RX and the HydroShift II LCD-S 360, based on our last check.

Lian Li HydroShift II LCD-S 360 CL White

Why we like it

On maximum fan speed it sits mid-pack at 2200 RPM: the H100i RGB offers 2400 RPM, and the Aqua Elite 360 V6 comes in at 2000 RPM. No other pick in this guide offers L-Connect software; compare the H100i RGB, which has iCUE software. You also get adjustable tube routing, a slim 24mm radiator 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. 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. Only the H100i RGB came close to it on price at the time of writing; it cost the most of the 5 picks.

Thermalright Frozen Notte 240 V2

Why we like it

Thermalright recommends a case wider than 250mm, so check the width. Its two fans reach 2,000 RPM at under 27.7dBA, and the ARGB syncs to a 5V header. It matches the Aqua Elite 360 V6 on maximum fan speed (2000 RPM).

It also comes with a pump rated for 40,000 hours and braided tubing. Check that your case offers 240mm 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. It was the cheapest of the group when we checked; the Aqua Elite 360 V6 was the next step up.

Strong Alternative5 of 5

Thermalright Aqua Elite 360 V6 ARGB

The Aqua Elite 360 V6 is the budget route to a 360mm radiator, listing a 2800 RPM pump and 2000 RPM fans.

Best for

Buyers who want round ARGB pump head.

Thermalright Aqua Elite 360 V6 ARGB

Why we like it

It suits a hot CPU when the budget is tight. Its round pump head uses Thermalright's fourth-generation pump, and the fans and block sync to a 5V ARGB header. The radiator moves up to 70.84 CFM.

The fans are pre-installed and daisy-chained, which saves motherboard headers. On maximum fan speed it ties with the Frozen Notte 240 at 2000 RPM. 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. When we checked, only the Frozen Notte 240 cost less, and the Titan 360 RX cost more. Maximum fan speed is its weakest area, and the H100i RGB covers it better at 2400 RPM.

A tower air cooler in a case with red-lit fans
The figures behind the order
We set side by side five AIO coolers on maximum fan speed, pump speed, fan size and zero RPM mode, using each maker's published specs. We did not test them in-house, and pump speed and zero RPM mode are missing for at least one pick.
What every pick has in common
All 5, from the H100i RGB to the Aqua Elite 360 V6, state maximum fan speed, fan size and sockets named.
Where the specs have gaps
The H100i RGB, the HydroShift II LCD-S 360 and the Titan 360 RX give no pump speed; the Frozen Notte 240 and the Aqua Elite 360 V6 give no zero RPM mode.
Price range
At our last check the picks ran from the Frozen Notte 240 (under $50) to the HydroShift II LCD-S 360 ($150 to $250).

What to Look for in a High-Airflow CPU Cooler
