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

Paired with the Thermal Grizzly Duronaut paste, 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 photo & video upscaling, batch video encodes and large software builds, I typically see temperatures in the mid to high 60s and occasional spikes into the 70s, which is completely normal for the 9900X and still well within comfortable thermal limits. I've also observed idle temperatures as low as 35c, but they usually sit between 36-39c (41-44c since it's nearly summer and ambient temps have risen considerably). The pump is very 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 to the motherboard, they ended up just a little 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 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.

Purchased for 5800x3d and I couldn't be happier. My previous AIO pump is assumed stopped working. And during games would sit at 91c. Assuming due to the CPU throttling. So I was not getting full power. Decided to replace it eith this one based on online recommendations and reciews. I could nor my CPU could not be happier. Now my CPU never goes over 70c. It runs at full clock speeds, including boost. I did personally undervolt the CPU with curve to keep my clock speeds. But it runs flawlessly! Couldn't recommend a better AIO cooler. And it works with Intel, and both AMD sockets (AM4 and AM5). The size is huge, make sure you do research to make sure it fits in your case/motherboard. For me, I use Lian Li Dynamic 011 Razer Edition with Gigabyte z570s Aurora ELITE AX. And I have room to push pull setup. Installation was not difficult with the videos from Arctic YouTube channel. Does not come with instructions. I did upgrade the Termal paste as well as suggested. I went with Corsair xtm70 instead.

*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:

She's chunky but I'm enjoying it! It is a little on the louder side but my tower is on my desk next to me. The install is a little weird with an AMD and I don't like that there's not a physical manual to reference and instead an online one with a QR code. At least it saves paper. Not necessarily a complaint, but the part that's rainbow on the CPU cover is NOT a fan. It's a hard plastic cover that covers the CPU fan and has the RGB capabilities. I thought it was a fan that was malfunctioning on install when it wasn't spinning. That's my bad. The temps on my mobo and CPU stay pretty low. Playing Diablo 2 Resurrected on the highest graphics settings and the temps got up to I think 40C at max? She's only been installed for two weeks so I'm not sure about lifetime or its durability just yet, but I'll try to remember to update if it peeters out early in its lifetime. Otherwise though she's been nice to look at and use!

I paired this with a 9800x3d and it cools it amazingly. I have been hesitant to make the switch from air cooler to AIO because I didnt think there would be much of a benefit as I was using a Noctua D15s. I had a 7600x3d and with the Noctua it would idle at 45 to 50c and during gaming sit at 60, during shader compile/heavy cpu usage it would go all the way to 72(capped max). With the Arctic LF3 pro 360 the 9800x3d idles between 30 and 35C and during gaming sits at 50C. The highest ive seen it go during shader compile was 65C. The LF3 is a beast! Idk if the 9800x3d just runs cooler but I was blown away with how cool the LF3 keeps the cpu. Also pro tip to make install easy, leave the aio mounting brackets a little loose (the 2 you install on the mobo). Then get both sides on and tightened and then go back and tighten the brackets. I heard people in the past having a tough time with the leaf spring style screws and I had no issue. I used the 3 separate fan connectors to make sure the pump was always going and had no issues using my cpufan 1 and 2 slots on my mobo to control the fans. The single cable would definitely make the wiring alot cleaner. Overall for the price I dont think you can beat the LF3 pro, backed with a 6 year warranty, its a no brainer. I wish I didnt wait so long to switch to an AIO! Also make sure you check the measurements as this rad/fan config does seem to be a bit thicker than other brands but its worth it with its performance. My one gripe was I couldnt get the RGB to work with the arctic software, it wouldnt show up but then I installed armory crate (crappy asus mobo software) and using aura sync I was able to customize the colors. I dont know what I did wrong there but that was a caveat I wanted to throw out. Overall I think if you buy this you will be thoroughly impressed if coming from an air setup like myself. Good luck!

I have no complaints at all whatsoever. The water cooler does its job very well and helps keep my 9800X3D's temps pretty cool during heavy, long hours of gameplay at 1440p Ultra settings. The RGBs are also a plus and add to the aesthetics of my PC build. I highly recommend it. I've had no issues at all with it. It includes the thermal paste/putty and brackets needed to install on your motherboard and CPU. 10/10 (Don't mind the horrendous cable management in my photos. Haha)
