Best 360mm AIO Liquid Cooler

The most capable 360mm AIO we’ve tested, the GA II Performance features a low noise mode which doesn’t result in performance reduction when paired with most CPUs. It’s also reasonably priced for its class, at $169.99.

2. Cooler Master Master Liquid 360 Atmos

Best 360mm AIO Liquid Cooler (Alternative)

The 360 Atmos is the best AIO that Cooler Master has made to date. It offers premium aesthetics, strong cooling performance, and quiet noise levels for under $150.

3. Iceberg Thermal IceFLOE Oasis 360mm

Best Budget 360mm

Iceberg Thermal’s IceFLOE Oasis 360 AIO delivers a stellar combination of performance, noise levels, and a lengthy 7-year manufacturer warranty. It also comes with RGB fans, which is particularly impressive given its $89 U.S. price.

4. Silverstone IceMyst 360

Best Multipurpose AIO Liquid Cooler

Unlike any other competitor, Silverston’s IceMyst AIOs have optional stackable VRM and RAM fans that provide additional cooling for other on-board components. CPU cooling results were also very good in our testing, with the best results we’ve seen from any cooler with the fans set to a quiet 38.2 dBA.

5. Corsair iCUE H170i Elite LCD XT

Best 420mm AIO Liquid Cooler

A large 420 mm radiator helps deliver the best cooling we’ve seen yet, and the IPS display is attractive and useful. Just be ready to pay up (and maybe buy a bigger case) if you crave this level of powerful and attractive cooling.

Reasons to avoid

Full Performance mode runs loud

Lian Li’s Galahad II Trinity Performance raises the bar for AIO Cooling. Every component has been upgraded, resulting in absolute cooling domination. The cooler installation is simple and easy, and it’s reasonably priced at only $169 USD. With results like this, I find it hard to recommend any other liquid cooler, making this the first CPU cooler I have ever awarded a 5-star rating. This is the best liquid cooler on the market right now, without question.

While cooling performance is absolutely amazing, thermals are only one part of the picture. How loudly the cooler runs is very important as well. In its default configuration, Lian Li’s GA II Trinity Performance runs loudly at 55.2 dBA. I’ve only tested a handful of coolers that reach this level of noise.

Normally I would consider this a mark against the product, but Lian Li wisely included a built-in low-noise/high-performance toggle switch, allowing you to reduce maximum fan speeds and noise levels with the flip of a switch. Most coolers that support low-noise modes have reduced thermal performance when engaged. But I didn’t observe any difference in thermals between the two modes when tested on my i7-13700K. When set to the low noise mode, total noise output is reduced to 49.2 dBA, which is on par withMSI ’s and DeepCool’s competing 360mm AIOs.

The attention to detail is apparent in its design, and the rated 160,000 hour-plus lifespans for the fans and 210,000 hours for the pump, combined with a 5-year warranty, show that Cooler Master truly backs the quality of its cooler.

Iceberg Thermal might not be the best-known brand in PC cooling. But its IceFLOE Oasis 360mm AIO is a great balance of performance, low noise, and price. If even two of those three criteria top your list of priorities, this cooler should be on your shortlist. Its temperatures and cooling abilities aren’t quite the best, but they’re not far off. And at 45.3 dBA at max noise levels, this cooler also isn’t the quietest out of the box (though again, it’s not far off the leaders here).

But when dialed into our noise-normalized 38.2 dBA (quiet, but still slightly audible to most people), the IceFLOE Oasis 360mm truly shines, delivering effectively the same watts cooled as the best performers in this benchmark: much pricier options from Lian Li and Silverstone. The IceFLOE is well worth considering for anyone after a quiet or budget-friendly 360mm AIO. If you’re after both, it’s arguably the best there is.

Fans run louder than they need to by default

Silverstone’s IceMyst AIOs show that there’s still plenty of room for innovation in the CPU cooling market. Apart from doing a good general job at CPU cooling, this cooler lets you add multiple fans ($16 extra per fan) around the base of the CPU block and direct them over your VRMs, RAM, SSD, etc. This is a feature unmatched by any existing product on the market. And the IceMyst coolers also cost less than many high-end AIO cooler alternatives.

In our CPU cooling tests, the IceMyst AIOs (we tested both the 360 and 240mm models) performed very well, usually landing close to the best-performing coolers in terms of chip-chilling abilities. And when all coolers’ fans are set to the same low noise level of 38.2 dBA, Silverston’s IceMyst 360 performed the best of any cooler we’ve tested, handling 237 watts. The 240mm model also did well, handling 228W.

My only complaint is that by default, the IceMyst’s included radiator fans run much louder than needed – but that’s easily fixed by implementing a custom fan curve. If fan noise bothers you, don’t worry too much because when set to run silently the 360mm IcyMyst provides the best noise normalized results I’ve seen from any cooler on the market.

Won’t get in the way of tall RAM

Reasons to avoid

420mm radiator severely limits case support

Expensive

Corsair’s iCUE H170i Elite LCD XT AIO offers the best cooling performance we’ve tested yet with Intel’s i9-13900K, handling over 325W in our most intensive thermal tests. And unlike other coolers, the noise level of the H170i Elite is tied to the CPU coolant temp, resulting in quieter operation during most common tasks and the elimination of bursty fan behavior. The tradeoff is that we saw noisier operation under the kinds of sustained loads that we use for testing.

The Corsair iCUE H170i Elite LCD XT is one of the best coolers currently available in terms of performance and features. It’s also quite expensive at $310, but if you don’t mind going without the pretty 2.1-inch display, the company also sells aniCUE H170i Elite Capellix XT with the same radiator and pump for around $240.

That’s still no small amount of money for a cooler. But if your needs are extreme enough to warrant a 420 mm radiator, you can probably afford to spend a bit extra on keeping your powerful CPU as cool as it can be under load.

Reasons to avoid

Display makes for an expensive AIO

Lian Li’s Galahad II LCD 280 shows that with the right design, you don’t need a 360mm AIO or a loud cooler to keep modern high-end CPUs from throttling. Its performance is amongst the best we’ve seen from any AIO, and its limited 280mm size means that it will fit in many cases where a 360mm model won’t. The included LCD screen is vibrant and adds eye-catching functionality to the cooler’s aesthetics.

At $229, the Galahad II LCD 280 is on the expensive end of the AIO spectrum. But if the LCD display isn’t your thing or you’re on a budget, the non-LCD versions of the Galahad II are available for $159.99 for the 360mm version and $119.99 for the 240mm model.

If you’re looking for a strong 240mm AIO, you can’t go wrong with Lian Li’s Galahad II Trinity 240mm. Our testing shows it’s the best-cooling AIO of its size on the market. It’s also quiet in most workloads, and it has a very reasonable price of only $119.99.

I never imagined that a 240mm AIO would have this level of cooling domination. Lian Li’s Galahad Trinity II Performance 240mm managed to sidle up to or outperform 360mm AIOs that were previously considered among the best available.

After installing and testing it, I found Cooler Master’s new MasterLiquid 240 Atmos especially impressive. It’s clear the company has improved its flagship AIO in several key areas. Noise levels are low in most common workloads, and despite its smaller 240mm profile, the 240 Atmos is one of only a handful of AIOs I’ve tested that’s capable of keeping Intel’s i7-13700K under its peak temperature, even in the hottest of workloads.

The attention to detail is also apparent in the packaging (which incorporates installation instructions) and RGB lighting. And Cooler Master backs the quality of this product with rated lifespans of over 160,000 hours for the fans and 210,000 hours for the pump, combined with a 5-year warranty.

Lian Li’s Galahad II Trinity Performance 240 cools just slightly better and sells for a little less. But Cooler Master’s Atmos includes an ARGB controller box for syncing your lighting with other components. If you can make use of this controller, which would cost about $20 on its own, the two coolers are effectively evenly priced.
