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

I recently replaced my previous AIO (MSI Mag CoreLiquid I360) with this AIO from Arctic. The MSI was slowly getting degraded from only 8 months of use. This is my first Arctic AIO and the first thing I noticed was the outstanding build quality. Installation was easy, my kit included the new MX-7 paste. My temps dropped 6c while gaming and the fans are noticeably quieter than the MSI AIO. The ARGB looks great as well!

Absolutely rocks. It helps me keep my Ryzen 9 5950X running nice and cool. I used to run pegged at 90c when playing games, but now I am running a cool 60c at 356 FPS with my RX7900 XTX. This AIO is sweet. Have this on a MSI MAG B550 Tomahawk Max teamed with Ryzen 9 5950X and RX7900XTX inside of a Corsair Frame D4000. Super air movement and running smooth and cool.

Definitely worth the purchase, if you're looking for a liquid cooler this is the one, keeps my CPU cool all the time and is durable, installation is direct and easy my first time building, during building my setup I had no need to worry about it being fragile, be careful though don't be too forceful it has it's limit but overall great quality

*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

Great value, looks super cool, only real complaint is no included physical manual, but, that allows for an animated online one, which is cool. Dropped my CPU temps several degrees C from the air cooler I was using. Pretty great all around.

Lives up to the hype, and I'm glad I got the updated version. Wasn't even aware this dropped until I went hunting the previous LF3. Installation wasn't difficult. Tubing is a tad long, but that's just due to my case having the mobo mounted a little higher. It fits fine and after a little adjusting there's plenty of room. Be warned: if you use the all-in-one cable you will not be able to monitor the pump or vrm speed.. that's normal. The pump will just run at the same % as the fans, so after some curve adjustments it's nice and quiet (and cool). Being it's got updated fans, and other small improvements over the previous LF3 I'd say it's a great value. If you get the black version then even better (at the time of this review the blk version is $88..). My case is a Lian Li 507, so it's a rather compact mid-sized case, and (while snug) it fits fine. Like a glove, even. A little over a cm clearance on the front and back, but oh so clean. After getting my fan curves dialed in properly (coming from a Peerless Assassin, which is still great) it runs cool and quiet-ish, as I stated above. This will have more to do with your case and other factors. I'm sure it's louder than other AIO, but I'm happy with it. Performance is solid. Installation was easy and rather fast. The online guide is great and interactive, depending on your chosen mounting method. And aesthetically it looks great. I do love that the face plate is removable, while the magnets are strong. Not sure why the "blades" you see are static (it's more of a grille), but the VRM fan appears to be substantial and u can feel a good bit of pressure coming from it...so that seems to be very functional. I hope they release a screen that's is compatible with this at some point. Edit: swapped to the split cable and adjusted my fan settings. WAY more consistent temps now. I had an issue with spikes where it would ramp up then settle once it was cool then ramp up. I'm sure this was more to do with my curve settings, but since I did this and set the VRM and pump speeds to a static 60% it's quiet and more cool than before. I also undervolted my CPU and I cruise at a solid 41C under load.

I’m running the Arctic Liquid Freezer III 360mm in a Corsair 4000D, and it’s been hands-down the smoothest AIO install I’ve ever done. Everything lined up perfectly in the case, the mounting hardware was straightforward, and the whole process took way less time than I expected. Once installed, it looks super clean—no bulky pump housing, tidy tubing, and the fans blend right into the build. Performance is where it really surprised me. I’m using it on a 9800X3D, and temps are excellent even under heavy gaming and stress loads. It’s quiet, efficient, and just does its job without any drama.

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
