Liquid Freezer III Pro 360 A-RGB - AIO CPU Cooler, 3 x 120 mm Water Cooling, 38 mm Radiator, PWM Pump, VRM Fan, AMD AM5/AM4, Intel LGA1851/1700 Contact Frame - Black

The Arctic Liquid Freezer III Pro 360 is keeping my Ryzen 9 9900X exceptionally cool. Under controlled 24‑thread stress testing—including sustained AVX/matrix workloads—the CPU holds around 62 °C, which is excellent for a processor of this class. In real‑world workloads like batch video encodes and large software builds, I typically see temperatures in the mid to high 60s and spikes in the high 70s, which is completely normal for the 9900X and still well within comfortable thermal limits. The pump is quiet, the radiator fans move a lot of air without excessive noise, and overall thermal stability has been outstanding. Installation was mostly smooth, but the CPU block mounting system needs refinement. Once the mounting brackets were secured, they ended up just a fraction of a millimeter too close together, which meant the two screws on the CPU block didn’t line up with their holes. I had to loosen the bracket screws, mount the block, then retighten everything. It worked, but it shouldn’t require that workaround. I also wish the block used four mounting screws instead of two for more even pressure. Despite that hiccup, the cooling performance is exceptional, and once installed, the unit has been rock‑solid. For high‑core‑count CPUs like the Ryzen 9 9900X, this AIO has more than enough thermal headroom for both synthetic stress tests and demanding real‑world workloads.

This is the second ARCTIC cooler I have purchased with the first being the Freezer II. I think it is a fantastic product. The price is great and it cools wonderfully. However, the thermal paste with both coolers was dried out. I went from idle temps being 40 even 50 C and fans annoyingly loud to 29C and fans quiet. Gaming was a big difference going from upper 80C to 60C. I am unsure why I had bad luck with the paste, but I would recommend this product regardless. Installation has even gotten easier and the RGB is pretty if that is your sort of thing. It fit my case, but it is a snug fit at the top of a Montech AIR 903 MAX. It seemed easier to mount this one than my other cooler and the screws was fairly easy to screw in unlike the last cooler I had. It is a hefty cooler and I think it will hold up nicely. The magnetic CPU fan is interest and simple to install. The RGB part does not spin so don't worry about that as the fan itself is underneath that.

Very good AIO, but it is LOUD if you do not set up your fan curve properly. I would also recommend setting the pump at a static 70 or 80 percent. With a good fan curve, this thing is whisper quiet and keeps my 9950X3D around 70c in AIDA64 stress tests. Haven't run any other extreme case benchmarks because I just don't feel the need to. Aesthetics are good, the option for one wire vs 3 wires is nice even if I would recommend using the 3 wire config, and having all the fans on one RGB header but still being able to identify each fan individually is great if you're someone who likes that. Would definitely recommend this AIO over something like a TRYX unless you absolutely have to have the screen that comes with the TRYX. Otherwise, it's hard to justify spending $250 when something like this performs just as well at a less than half the price. Just make sure you have the clearance in your case. The radiator is a beefy boy.

Update: I swapped my CPU for 9950x and still doing well (needed more cores). With PBO on, it would hit 95C, but without it would hit 80 on stress tests. It's normal for this chip to squeeze out more performance until 95C, so it really isn't the fault of the cooler. I did use a negative optimizer curve with PBO and now it stays in the 80s when fully utilized. Still a great cooler and would recommend. Original review: This thing has amazing performance. My 9800X3D CPU was originally cooled by a 240mm AIO (NZXT z53) and during Cinebench runs or any stress tests, it would hit 95C - verified install, repasted, etc. but had the same results. I installed this and it would go 82C max during my tests. Huge difference and now I can rest easy knowing my CPU won't be hitting 90s. Idle still sits around 40C but that's with a general fan/pump curve and not aggressive. Gaming will hit around 60-65C. This is for the 9800X3D chip, so it will vary if you have a different one. Install was OK compared to most, but it doesn't seem as stable when you mount it, as you have two screws to mount it into place compared to corners like some others. But it's not bad, especially if you have built PC's before. The instructions are online and very easy to follow. Just know that the radiator is much thicker than "regular" 360 AIOs, so make sure you have room in the case before purchasing. The RGB is ok, nothing fancy. Not amazing for 2025, but the price also reflects that. The fans have a slight gap at the top so the LEDs do shine through, seems nice, like an aesthetic thing. Performance is obviously not an issue as stated above. This cooler is definitely the best bang for your buck for 360mm AIOs. I got this on sale for $99, so it was well worth the price. I'll update this review if this has any issues down the road

questo dissipatore a liquido Arctic merita 5 stelle per il suo rapporto qualita' prezzo imbattibile. l'ho acquistato per raffreddare il mio ryzen 7 9800x3d e fa il suo egregio lavoro. PRO: - esteticamente molto bello e i led funzionano molto bene. - raffreddamento ottimale in ogni situazione, anche dopo ore di gaming. - facilita' di personalizzazione tramite app di terze parti. (alta compatibilita'). - rapporto qualita' prezzo imbattibile. - nella confezione ci sono tantissime viti per adattarlo al meglio in ogni case. CONTRO: -dissipatore molto grande e spesso, non tutti i case sono compatibili. soprattutto per quanto riguarda la parte relativa al radiatore che risulta essere molto spessa. dal mio punto di vista puo' essere montato solamente in case atx grandi. nel mio caso e' stato montato nel case piu' grande della msi e c'e' stato giusto giusto.

I mean - it is the goat for a reason. There is not much to say, it is massive however and the fans are too noisy. I replaced them because 3000rpms is not necessary, 2000rpms is good enough for my use (video editing and gaming). Make sure you have the clearance and know what you are doing. Some people hate this because it takes a brain to build with this. I replaced my wonder vision 360 for this and my Ryzen 9900x is idling around 41c ( this cpu is known to idle around 50c). My CPU is undervolted per CCD -25/20 (too lazy for Core tuning) and overclocked and I don’t reach 75c even in OCCT. Gaming is around 56~61c and video editing 65~70.

Good prebuilt aio cooler easy to install, has a cpu fan as well on top of the water pump revs like a v8 haha. Thermals are in the mid 50 degrees Good cooler thermal paste could have been fresher but all good Good deal

Installed the ARCTIC Liquid Freezer III Pro 360 A-RGB in a recent build and it’s been absolutely spot on. Cooling performance is excellent. The 360mm radiator and 3 x 120mm fans handle load without breaking a sweat. Temps stay impressively low even under heavier workloads, and it’s noticeably quieter than I expected for something moving this much air. Build quality feels solid — the thicker 38mm radiator definitely gives it that “serious bit of kit” feel. Mounting was straightforward, and everything lined up nicely without awkward wrestling inside the case. The A-RGB lighting looks clean and well diffused, not harsh or patchy. Most importantly, it works perfectly with ASUS Aura Sync. Synced up straight away and matches the rest of the system without any RGB software drama (which honestly deserves its own award). Pump noise is minimal, fans ramp smoothly, and overall it just feels premium. If you want strong cooling performance with good aesthetics — especially in an Aura Sync build — this is a fantastic choice. Five stars. Keeps things cool and looks the part doing it.
