ARCTIC 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 60–62 °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 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.

An amazing looking and performing cooler. After looking at many reviews I finally decided to give water cooler a try instead of Noctua air cooler I had originally planned. Installation was very straightforward and the Youtube tutorial was very helpful in mounting it. The thermal performance of the cooler is excellent for my OC'ed Ryzen 7 7800x3D CPU. Temps never cross 67 - 70C even at full load (depending on room temps).

*Update*: RGB works flawlessly GREAT product for AM4 CPU's. I have been looking to replace my aging Corsair H100i Pro AIO, which I bought in 2019, for some time now. After I read all the glowing reviews, I was really excited to get this cooler. I did not see many reviews from folks with AM4 processors, though, so I was a little bit wary, especially when the instructions said not to worry about some of the chip being visible after install! D: I need not have worried. This cooler dropped temps about ~14 degrees C across the board. Went from 80 degrees under load to 66! Idle went from 50 to 36. For reference, I have an AMD R9 5900x, one of the hotter-running AM4 chips. Also I do have PBO enabled! (check screenshot for temp/load details). As others have stated, the radiator on this unit is quite large/thick, so make sure to measure your case to make sure there is room to accommodate it. My mid-tower case is old, but quite roomy, so I luckily had no trouble fitting it in my case. It is also significantly louder than my old two-fan cooler, but its not even as loud as my GPU, so I am not particularly bothered. Others may be, though, so you may want to modify your fan speed curve. Installation was not particularly difficult, and did not take much time. I found instructions using the QR code on the box (click on the 'Manuals' tab), and they were more than adequate. They included some graphics, gifs, and videos. I have a few decades of exp building PC's, so take this with a grain of salt, but I think beginners will not have too much trouble with this install. The trickiest part was removing the standard AM4 mount brackets and installing the ones included with the cooler. I had to hold the backplate (on the back of mobo) with one hand, while I installed the brackets one screw at a time. Bit of a pain, but the results were worth it. The only (and biggest) con, is that the MX-6 thermal paste included with the cooler had the consistency of silly putty. It was basically a solid. Seeing as the 8G MX-6 tube I bought, to replace the minuscule amount that arrived with the cooler, had a more viscous consistency, I assume it was a bad batch. This delayed my build by a period of two days (while waiting for thermal paste to arrive), and is the only reason why I am giving this product 4 stars instead of 5. I have not tested ARGB functionality, since I do not have a header on my old X570 motherboard, but I have ordered a header for it, and will update this review once it arrives. In short: buy this cooler for sure. Great value for money, and incredible performance. But!! Make sure to order your own thermal paste, because they may include Playdough in the box instead of actual thermal paste D

Keeps a overclocked cou really cold, best sub 200$ cooler out as of 2026 Handles 250watt amd cpu easy, and doesn't choke with a 800 watt modded 5090 inside pc making alot of heat Fans are good too, no need to replace them, rgb is good on them but I don't personally use it, hard to sleep next to. fans are fast when there needed but quite when not. Very very thick, make sure your motherboard doesn't clip it, my friend had a clearance issue with it in his case, but it fits in mine

After many aios ive landed on this arctic liquid freezer. I did not want any screen and this is not a bad looking aio. Temps are great and it is overall pretty quiet espicially after dialing in fan curve. I assume the vrm fan goes off of the pump speed but I set it to always run at 65% and I dont hear a thing. Also had no issues with installing, just make sure the mounts are the right way and its easy to install but could be a tad more difficult compared to other brands mounting brackets.

very good AIO and easy RGB control

No es posible instalar en mi gabinete Balam Rush Tank Master 9600 TB ya que es muy grueso y provoca interferencia con los disipadores de la placa base ASUS TUF Gaming B650-PLUS por lo tanto no lo puedo usar, se debe de revisar el espacio disponible y gestionarlo antes de hacer la compra Pero sin duda es la mejor opción para un procesador potente

Seni üretenlerin eline koluna sağlık güzel soğutucum. 9800x3d kullanıyorum 2k oyun + yayın + kayıt + sayısız çalışan program vsvs %98 çalışırken 50 derece sabit üstünü görmedim. Kasamdan klima gibi odama soğuk hava geliyor abartmıyorum oyun oynarken elim terleyince fanların üstüne tutuyorum..

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

Montato per una cpu amd. Attenti! Anche se è un 3 ventole da 120mm (tot 360) il radiatore è lungo 398mm, ed è anche piuttosto alto. Nel mio case MSI MAG FORGE 321R AIRFLOW c'è stato giustissimo, per fortuna. Ho dovuto collegare i cavi di alimentazione della scheda madre prima di installarlo o non avrei avuto spazio per fare passare gli spinotti. Controllate bene se può starci se avete già il case e magari scheda madre tra le mani! Se dovete montarlo e non siete esperti, fatevi aiutare da qualcuno che lo tenga fermo nella fase di ancoraggio sopra al processore, che richidede di spingere un poʻ. A parte questo, svolge il suo lavoro benissimo, ed è molto bello. Se settate bene la curva della ventola da bios o dal software della scheda madre, a temperature basse è estremamente silenzioso. Ci sono 2 opzioni per il cavo di alimentazione, uno che controlla tutti gli elementi in uno (ventole e pompa), e un altro che divide i controlli in 3. Per i principianti è consigliato quello unico, ma onestamente questa è la fase di montaggio più semplice e potete tranquillamente scegliere quello diviso, così potete anche settare curve diverse per ventole e pompa dato che vengono usati in quantità differenti e fanno rumore in quantità differente. La pasta termica era molto solida e ho fatto fatica ad applicarla, ma penso sia perchè l'ho lasciata al freddo. Unica pecca: la documentazione è davvero terribile. Se volete essere sicuri dovrete cercarla a mano in vari punti: io ho usato un video su youtube per il montaggio, uno short per la spiegazione dettagliata sui 2 tipi di cavi (entrambi i video sono ufficiali), e ho navigato la pagina di supporto per trovare i settaggi per le curve consigliate. Per favore unificate tutte queste informazioni in una unica pagina di installazione!
