Liquid Freezer III Pro 240-240 mm AIO CPU Cooler, Water Cooling, 38 mm Radiator, PWM Pump, VRM Fan, AMD AM5/AM4, Intel LGA1851/1700 Contact Frame - Black

I've installed quite a few cooling systems in my years but this one did give me a little bit of trouble due to the packaging not coming with instructions. The video guide skips a few steps as well but once i figured it out, it went on like a glove. I got this for a 12th gen i7 cpu LGA 1700 and while trying to install the cooling plate onto the cpu, I was trying to turn it to optimize the hoses not hitting any other components which caused the plate to be upside down. Trying to install the plate upside down when the bracket is right side up makes it impossible to screw into (good design but wish there were some instructions that stated not to attempt it). Once i got it mounted and tightened up though, i fired up the computer and it was super quiet sitting at idle. I dont even notice the fan noise unless im stressing out the system and even then, they are quiet compared to my previous cooling system. I've overlocked my cpu to its max and tracked it using AI Suite 3. It's keeps my cpu at sub 90 F at idle and under 110 F at 100% load (video compression, gaming & streaming simultaneously) which is quite impressive for the price. I was a little skeptical about the quality of this because the box arrived heavily damaged and semi opened but its really sturdy and a great size for a mid size ATX tower.

It's quiet, sturdy, and cheap. Offers the same thermal performance as the 360mm triple fan version, so save yourself some money and buy this one! Consult ARCTIC's motherboard compatibility list before you buy, and use PC Part Picker's website to determine compatibility with all your PC parts. As for installing, I recommend using the triple header wire and NOT the all-in-one so that your performance will be more optimized. Pay attention: 1. FAN cable gets plugged into the motherboard slot that says CPU_fan 2. PUMP cable goes into the motherboard slot that says PUMP. If not available, use CPU_OPT or a SYS_FAN header. 3. VRM goes into any SYS_FAN header. As for installing the unit itself, the ARCTIC youtube channel has easy to follow video guides on how to install them. However, you should know that your CPU backplate will fall out after you remove the original bracket. To make installation a lot easier, make sure you open your case's side panel so you don't have to remove the motherboard for installation. Way quieter than stock intel fan, and better performance, too. Stays quiet even when doing high-res video editing. Buy with confidence.

I bought this for my Intel i7 11700k that was using a traditional ThermalTake cooler. It was running so hot that the computer would shut off to protect itself. Running HWMonitor it showed that the CPU cores would frequently hit 100 degrees (C). I tried cleaning the processor and re-applying thermal compound, which made it slightly better. Once the new cooler was installed the CPU runs at about 25-30 degrees when idle and has so far peaked at 63 degrees under load. Had I not seen the before and after with my own eyes I would have a hard time believing that a cooler could have such a huge impact. Dropping 35-40 degrees is significany, so say the least. It was easy to fit inside my case and the quality of the build is excellent. One thing I will say is that the cooler has two options for power, one uses a single fan header and the other uses three for individual fan controls. Make sure you have enough fan headers for the application you prefer. Very quiet operations so far, even under load.

This cooler is so much better than my stock cooler. Easily keeps my CPU 15°+ C cooler while gaming and is reasonably quiet. Great value for the price and comes with thermal paste too. I brought it in to best buy to have it installed because I didnt want to deal with rewiring everything, but installation seemed pretty straightforward otherwise. Im sure people more experienced with computer builds would have no issue installing it themselves. Only thing I noticed was the radiator seems to get much hotter than my old one, so make sure your computer case has good airflow or it may be an issue.

The good news is: a great cooler -- effective and quiet, with good VRAM/mobo airflow coverage -- for the size. So for what you buy an AIO for, if 240mm is your size target -- and it fits, see below -- then you can hardly go wrong. It is rather nice that Artic does not over-price this unit. BUT . . . if you have an AM5 mobo, be prepared for some frustration in the install. There are two major issues: firstly, Artic's cold plate mounting is "offset" a few mm from the center of the socket, and that is done for a VERY good engineering reason: the offset assures that pump's cold plate is centered on the heat-producing part of the CPU's die. BUT that offset means that, with some mobos, aluminum cooling blocks/fins for VRMs or M2 drives conflict with the edge of the pump housing. You do not want to have this problem, so check the Artic website for compatibility; mine was. It is possible to mount the pump "backwards"/upside down, but that brings some other problems in your install like conduit routing/bending. Secondly, Artic intentionally "warps" their pump's coldplate so that the center slightly bows out, and the two binding screws torque down the plate firmly across the CPU's heat spreader. This is a good thing and, for example, it pretty much assures no air bubbles in the thermal paste. BUT that means that the binding screws slightly point out and are not parallel to the path of the threaded mounting holes. So it is a pain to get the "second" screw threaded (the first one goes in). On a mobo you never want to force things, so you have to be careful and take your time. Mine took 15 minutes and a little cussing; i do not look forward to re-applying paste in a few years. But all works now, quite wonderfully. My 7900x is running quite comfortably on all practical applications (LLMs and large advanced image processing) without throttling and with PBO enabled. The only benchmark that i could get it throttle on is extended Prime95 sessions, which is a rather severe and synthetic test in my opinion. So i am happy indeed. -- gary ray

This is a highly reviewed and rated aio cooler. Most people get it because of that. But having ran air coolers for decades, this is my first AIO, and I have several thoughts below. First of all - you don't need a water cooler unless your CPU draws lots of power, or you run extended CPU intensive things for extended durations. A good air cooler is more than sufficient. Spend more on water only adds to money and potential failure points. I ran an air cooler for almost 16 years and the fan still held strong. So why did I go AIO? For the novelty mostly, and because I applied thermal paste poorly in my last build and had higher temperature than I expected. By comparison, the AIO kept my CPU 10C cooler than my air cooler - due a combination of better thermal paste application, and it being a brand new, undirtied cooler. Some tips on getting the most mileage out of this unit. First, fan speed above 50% is loud. I set my fan curve in my bios to keep 50% until I hit 70C, which is very unlikely with my 5700X3D. Second, this device is noticeably louder than my air cooling setup. The reason being that the air cooler has top panels to deaden the noise, while this exposes the whole case to sound. For an easier install on AMD, do not tighten down the side brackets first. You'll need to secure the cooler to them first, and the extra little leeway will make your life much easier. And there's a backplate to your motherboard that you will screw into -- do not unscrew everything at once. The backplate will fall out, requiring you to reattach it. Instead, remove just one side and attach a bracket from this kit. It'll save you a lot of time. Finally - this does cool very well. At 50% fan speed, the noise is pretty acceptable. Overall - only buy if you need the extra cooling. These things wear out, so 6 years is probably time to get another one, vs 16 years on my air cooler. But if you do want to try this out, it's a pretty good product.

I knew installing this is a huge PITA. I have the 360mm model that I build my bed setup with. The 360mm was fantastic other than the insane 2 screw install mounting that is hard to do.... why they couldn't use a 4 point mounting system is beyond me. Especially when its REALLY hard to do the 2 screw install. Even Gamers Nexus said so in their review video, BUT the performance from Arctic is USUALLY pretty good considering the price vs other AIO's.... So why the 1 star on this one? I review it like I receive it. After struggling once again to install, I boot my pc up and there is a HORRIBLE noise as the fans ramp up. That's right, I am knocking it down to 1 star over the sound of something not working correctly. ALSO, my temps were generally high and the place where the rad met up with my case was "remove your hand or get burned" hot. Maybe the pump wasn't turning? no idea.... it wasn't good. But windows reported the pump speed and changes when I changed power to it.... usually PWM stuff doesn't report a functional number its its not spinning. So.... Anyway, I Remove the VRM cooler and the sound is still there. Get into windows and turn the fan speed down to 25%. The sound gets quieter. Turn the fans back up to max and the sound comes back and even louder since I was forcing 100% fan speed. I mean a horrible buzzing noise. The radiator was installed top of the case so in terms of air bubbles there should be no issue. NOT TO MENTION I had installed the housing upside down so the tubes were at the top instead of bottom. Which means any air bubbles inside should have made their way out. So I know air wasn't the issue. In fact, I even set the pump speed to the lowest I could, and then ramped the fans back up, sound still there. Okay maybe its the fans, troubleshoot. Remove the arctic fans and replace them with 2 other arctic fans I had lying around (arctic p12pro). Same issue, horrible noise. Remove those fans and install some old brown noctua's that I konw were fully functioning without noise (completely ruining the aesthetic) and the noise is STILL THERE. Removed fans once more, checked the fins to make sure none of them were damage or bent. Perfect fin array.... So clearly I got a defective unit. And guess what, now they get 1 star for it. Should I pack it up and return it? Absolutely, but I'm lazy. And now I know to steer clear of Arctic Products. Also I dont save boxes so technically I dont have a way to ship it back. Its fine, the dump will enjoy having a complete POS taking up space.... I tell it like it is. I have been building computers for over 20 years and never had a defective AIO from any manufacturer. Even my 360mm from Arctic is mint and works perfectly. But this isn't a review about the 360mm its a review about the 240mm.... Oddly when I go online to forums and such places I see a lot of people complaining about Arctic 240/280 products being defective. Interesting right? Many say pump not working, pump noise, etc. Yet for some reason I can't find anyone complaining about the 360mm product. IT SEEMS TO ME, they put all their work into making the 360mm the best, and then half-@$$ed the 240/280 units. Again this is my opinion on the matter. But that's how it seems. I would steer clear. What did I replace this defective unit with? The brand new MSI A13 liquid cooler. And since I was so angry about having to take apart my PC to fix everything, I decided to just ruin the color matching and put all noctua fans inside. I now have push/pull on the MSI 240mm AIO using the legendary NF-a12x25 fans, same fan for rear exhaust, and 2 slim noctua NF-a12x15 at the bottom of my Jonsbo D32PRO. Picture is of my updated build using the MSI AIO because EFF Arctic for selling me a defective product. Do your Quality Assurance better.... this should never happen in 2025. Side note. If you are wondering from the picture how my PSU can be so freaking long and still fit? Its the Corsair RM1000X SHIFT. The cables come out the side. That's why the fan is facing inside the system. As the cables run out the rear. And yes, that motherboard is a back connect Project Zero board form MSI (b650m). So all the connectors are on the back which makes it STUPID clean. T-Force ram is matched silver/silver with the motherboard and ARE on the MSI memory support list. So its running rated DDR5 6000cl30 speeds with my 7800x3d. I also have the special thermalright retaining mount for the CPU (not using the stock level arm lock). The GPU funny enough has that zero fan speed mode for resting/low temps and because my bottom fans are full blast and seriously quiet) my fans dont even kick on unless im playing some AAA game that requires the fans to kick on. And even then they don't ramp up to any audible level. Its a sick build.

I couldn't fit a 360mm but this one works great and has kept my Ryzen 9950x3D at a cool 40℃ 99% of the time. To be fair though, I haven't put it through any CPU bottlenecked tasks yet. Nonetheless, I'm super impressed it's stayed this low without any consideration on my part. Fits the top mount of the Fractal Design North case - I wouldn't attempt a 280mm one unless you go with a special motherboard - my VRM heatsinks on the top of my MSI Pro X870E-P touch the side of my 240mm as is. One downside was how difficult it was to install – I'm not the biggest fan of their spring loaded screws. You need to turn them a bit in advance (even if they don't say it) so you have enough threads sticking out to align with the AIO mounts/brackets. Otherwise, you may make the same mistake I did and end up smushing your thermal paste too much before managing to mount it. The hoses are pretty stiff so getting the placement right first try is tricky.
