Customer Ratings & Reviews

It's fine. I had lost the AMD hardware to my thermalright cooler and needed something for my platform change. Wouldn't spend this much on a 240 again.

Cooling-wise, this AIO is fantastic — temps stay low, it runs quietly, and installation was straightforward. But the RGB side of things? A headache. This cooler doesn’t support iCUE, and getting it to sync with motherboard software is hit-or-miss. If you just want solid cooling with a rainbow effect, it’s fine. But if you care about customizing your lighting or syncing it with the rest of your setup, be prepared for a frustrating experience. Great cooler, frustrating control.

The installation is smooth, the included extension cables for fans and ARGB make life easier. The performance is also great, it keeps my CPU 1-2 degrees cooler than the NZXT X53 I retired. I was so happy to see a Corsair product that didn't force you to use iCue software...but there's a catch. The ARGB is only Gen 1. This seems like Corsair's way of punishing you for choosing the ARGB version of their cooler. Gen 2 has been around for years, and allows each device on a header to have it's own lighting controlled. By contrast, Gen 1 devices on the same header will all be lit the same. This AIO's pump and fans will all be the same color/pattern. If this was Gen 2 (any product in 2024 should be) then the pump and each fan would be a separate device and could be configured however you would like. The product images all show different lighting per device, which seems deceptive. If you want simple lighting, then this cooler works well and looks good. If you prefer more fluid/complex lighting setups, look elsewhere.

super easy to install, and very quiet. runs my cpu much cooler than my previous AIO did.

I had a generic AOI cooler from newegg prebuilt and pc kept shutting down, just bought this and had zero issues for 6 months now. This 240mm AIO cooler delivers top-tier cooling performance, keeping my CPU impressively cool even under heavy gaming or rendering loads. It handles overclocking with ease, ensuring consistent, high performance. What really stands out is how whisper-quiet it is. You get powerful cooling without any annoying fan noise, which is fantastic for focus and immersion. And the ARGB lighting? Absolutely stunning. Controlled by iCUE software, the vibrant, smooth illumination from the RS120 fans and pump head adds a premium, personalized glow to any build. In short, the CORSAIR NAUTILUS 240 ARGB is an outstanding cooler. It perfectly blends superior cooling, quiet operation, and captivating aesthetics, making it an excellent investment for any high-performance PC. Issues: Not suffiecient documentation on how to wire some of fans and cooler

Easy to install and good quality! I returned the Thermaltake TH120 ARGB, which it was very bad, and i got this! I’m so happy of my purchase, my Computer works much better! I strongly reccomand this product!

I installed the CORSAIR NAUTILUS 240 ARGB Liquid CPU Cooler on my Ryzen 9 7900X, coming from a smaller 120 mm cooler, and the improvement was immediately noticeable. Temps are far more controlled under load, and overall system stability is much better during gaming and heavier workloads. While it doesn’t have the same thermal headroom as a 360 mm AIO (as expected), the 240 mm radiator with dual RS120 ARGB fans handles the 7900X well for daily use, gaming, and productivity tasks—without excessive noise. What stood out: Noticeable upgrade from 120 mm: Lower and more stable temps across workloads Handles Ryzen 9 7900X well: Keeps thermals in check for gaming and multitasking Quiet operation: Fans ramp smoothly without getting loud Clean ARGB look: Subtle, customizable lighting that doesn’t overpower the build Straightforward install: Solid mounting hardware and clear instructions What to consider: For extreme stress testing or sustained heavy rendering, a 360 mm AIO will still run cooler Make sure your case supports a 240 mm radiator (top or front) Added value with Totaltech: Having Best Buy Totaltech added extra value to this purchase. The 2-year protection makes upgrading core components like a CPU cooler feel much more comfortable. Bottom line If you’re running a Ryzen 9 7900X and upgrading from a 120 mm cooler, the CORSAIR NAUTILUS 240 ARGB is a solid and noticeable step up. It delivers reliable cooling, quiet performance, and a clean aesthetic—making it a great choice for high-performance builds that don’t have room for a 360 mm radiator. Highly recommended for balanced performance and everyday reliability.

great product, easy install . PC is happy we installed it. kids on it all day and it keeps iit cool

So much quieter than my old AIO. I’ve had no issues with CPU temp since installation, and installation was pretty easy.

Works great and is very quiet, very nice quality and look very sleek

I purchased this because it was low cost and didn't need frills. Never expected i'd love this so much. it's extremely quiet when cpu is idle, gets louder under load like it should but not very loud and keeps my cpu (9950x) very cool. The heat coming out of the cooler is crazy when the cpu is at 80% and the cpu stays cool max 85c from what I remember. My case stays cool so my 4070 super stays cool. highly recommend

Easy install help my cpu from stop over heating went from 90°c to 45° , WOW!

I bought a prebuilt and it came with a fan cooler and I decided to switch to a pump. The pump keeps my PC at a nice temp while gaming and just working, its also very quite compared to my previous fan cooler.

Really? Easy to install also comes with thermal paste already installed onto the cpu cooler, and the fans work amazing with the motherboard's rgb

Easy installation and great price, keeps my CPU 10 degrees C cooler than the stock CPU fan.

Amazing product used it before but i had to return it because i didnt realize that it was too small for what i was looking for. But regardless i absolutly recommend this.

Keeps the cpu cool really well for the cost. Plus its very simple and high quality.

Excellent cooler, easy to install. Looks really good in the case.

Good AIO, cools cpu quiet well. My old pump broke so ran to my local best buy and got this one and am not disappointed. It runs pretty quiet as well. Very happy with my purchase.

No complaints about it's performance. However, the fan's cables are laughably short. They barely extend 2 inches out? Just be prepared to order, or have, some extenders. Also, this fits AM5 perfectly.
