I bought an extra-large computer case so that I could accommodate 3 x 140 mm cooling fans. This is cooler is a beast. Thus far, I have yet to see my AMD CPU show temperatures over 50 deg. C, even under 100% load. My only observation is that the fans are a little bit loud, but this seems like a small price to pay for the excellent performance. Read more

I'm writing this as of 2 days of use after installation on an I9-14900k, one of the hottest-running and most troubled processors on the market. It is installed on the front panel of a Fractal North XL case, with fans in front in an intake configuration. This seems ideal to intake cold air instead of using the already hot air within the case to cool the radiator, and to avoid the convection heat from being at the top of the case. These conditions seem minimal but should increase thermal performance. The Bad: *Amazon lied about the shipping. Under the product listing, it claimed next day shipping, and then when it was in my cart it would only offer 2-day shipping. *Installation was a little weird as there was no rear bracket and I used the one I had from another aftermarket brace, which fit. Not a big deal for me, but some people may be confused or be missing a back bracket for LGA1700 chips. *Tightening the 2 screws on the pump header was a bit nerve-wracking since they had such heavy resistance and there's no physical instruction book. *The front panel of the Fractal North XL doesn't seem to click in fully with these big fans in the front, but I'll figure that out later. *The noise at full load is significant, but not really a problem for me since my headset has good ANC. *The "pseudo-fan with small fan inside" just magnetically clips onto the pump header. I'd feel better if it clipped on or screwed on. *The fan power cords that go through the water tubes are not long enough for the config I chose. I had to pinch the power cords a bit to get them in the front of the radiator. The Good: *That said, this cooler completely solved my temperature issues. I previously had an NXZT Kraken 360mm, and it was absolute garbage. One of the fan bearings went bad and made a ton of noise after just one year. The LED screen on the pump header never worked. It was either defective or just entirely inadequate for my processor, which is INSANE for how much I paid for that AIO (320$ at the time). I have been through hell trying to get this processor in a functional state between the BIOS updates and custom BIOS settings to limit voltage, and I was regularly pegging 100c on Battlefield 6 and other demanding games. I have it thermal throttled to 100c, but was is not ideal. *With the Liquid Freezer III Pro 420, I have not seen temps over 70c peak. Battlefield 6 causes that peak but runs at around 60-65c. Cities Skylines 2 is running at 55c currently. *The price point for this beast of a cooler cannot be beaten, especially if you don't need the LED version. All the bad points honestly negated by how relieved I am that I have my temps under control with this ridiculous processor plagued by issues. Whoever wrote the default intel settings and/or bios code must have lazily used AI and didn't troubleshoot or test it at all. Read more

Top AIO! Sehr leise, extrem gute Kühlleistung und einfache Montage auf AM5. Der VRM-Lüfter ist ein super Extra. Ziemlich groß, aber wer Platz hat, bekommt hier das beste Preis-Leistungs-Verhältnis auf dem Markt! Read more

Excellent cooling. Value for money . Good quality . Looks simple no RGB lighting which would be enough anyways unless you prefer tons of lighting. In default it’s silent and when it needs to throttle there is lots of noise but it gets your cpu cooled pretty effective. Read more

Don't take my word for it, just go on YouTube and watch GanersNexus review it. Both the 360 and 420 score amazingly and if you don't like all the rainbow vomit like me, you won't be disappointed. Read more

absolute beast of a cooler, easy to install, the brackets are marked left and right and the instructions are very clear, the fans are wired into the cooler so no mess with wires and cable ties in the back of your pc, the splitter is very clever having the option or either a uniform connector or 3 individual connectors for the fans, the pump and the VRM fan, no surprise but i installed this inside my meshify 2 xl which is more than big enough to house this monster of a radiator Read more

Best aio 420mm ! mais terrible coil whine sur un des fan :( Read more

Certes, il n'y a pas de notice fournie avec l'AIO, mais celle ci se trouve très facilement sur le net. Le montage m'a pris 15 minutes. Attention le produit est vraiment très imposant, il faut prévoir un boîtier adapté. Concernant son efficacité, je l'utilise pour refroidir un AMD Ryzen 9 9950x3d, avec la pâte thermique MX6 fournie dans la boîte. Contrairement a certains avis, je suis très satisfait de ce produit, pour le prix, il est capable de maintenir mon CPU a 72 degrés en stress test sur CPUZ pendant de longues minutes. En jeu, la température ne dépasse pas les 55 degrés. Brancher avec un seul câble qui gère a la fois, les ventilateurs et la pompe il suffit de quelques réglages sur la courbe de ventilation dans le bios du PC pour avoir un produit efficace et silencieux. Pour le prix, peux pas mieux faire. Read more

I recently upgraded my entire system from a RTX 4090 to a RTX 6000 Pro and my RAM from 64GB to 96GB respectively for AI workloads. The kicker? My power behemoth of an i9 14900KS was bottle necking the entire system due to temps on a Corsair 360mm AIO, I’m talking hitting 90-100C in high-core gaming like Star Citizen causing my clocks to drop as low as 5.2GHz, running into blue screens if I had my clocks any higher than 5.5GHz pc/4.4GHz ec and ran any sort of video editing, benchmarks or AI workloads. As soon as I stuck this thing in the system I was hitting 5.9GHz across all cores while playing any games or doing any AI workloads at around 75c/85c, now obviously in a CPU benchmark it will thermally throttle but nowhere near as bad as before it can maintain 90C at around 5.6/5.7/5.8 fluctuations instead of the 5.2 on the 360mm Corsair AIO. Overall, thanks for such a good (insert word here) product Arctic - keep it up! 👍🏻 Read more

The good: -Keeps a 9800X3D system cool as can be (around 40c idle/45c typical load) with fan speeds as low as 50%, so there's plenty of thermal headroom. -Quiet as a mouse. I'm fairly certain my chassis fans are louder than this thing. -Unlike the last two CLC's I've built with, the fans are already pre-mounted (as exhaust) so there's a step saved. -With the sole exception of the mounting screws, assembly and installation was a breeze. -The non-RGB model, at least, is crazy good value for the overall performance. The not-so-good -The included MX-6 paste was extremely thick, almost to the point of being a bit lumpy, and preferred to stick to the tube's nozzle rather than the CPU IHS, making it's application much more difficult than I'm used to. Based on thermals, I was still able to get it done correctly and it's working as intended. -No printed manual is included, just some QR codes the bring up a YouTube video. While the video is certainly adequate, a small set of printed diagrams would be much easier to reference than trying to awkward seek to a specific point on a video with my phone. -The mounting screws on the pump block were a bit difficult to line up with the brackets, and it took me a few tries to finally get them both started.
