ARCTIC Liquid Freezer III Pro 360 - 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

So for those that do not want to read the review, I'll just say it is an excellent CPU water cooler, and a must if you have a higher end CPU that likes to run hot.Now for those that want to read more, here's my review:Before I start with the details, I definitely need to stress that is imperative that you measure your case before purchasing this CPU cooler, since the manufacturer isn't lying, it requires a lot of space. That being said, if you have a case that can handle it, it works great and keeps the CPU nice and cool.Okay so on to the review. The reason I purchased the Artic Liquid Freezer 3 Pro is after building a new system with an Intel Core I9 processor, I found that the CPU cooler I purchased for it (Cooler Master 120L) wasn't really rated for such a powerful CPU, and under load the CPU temp was hitting 85c. Now 85c isn't a killer if it's just a quick spike, but when doing video encoding it was hitting and staying at that temp, which just isn't good for the CPU. So doing a little more research, I saw that Artic Liquid Freezer 3 Pro got great reviews, and was recommended for high end processors like the I9.Installing the Artic 3 Pro is extremely easy, unfortunately I built the system in a smaller full size tower case, and the new CPU cooler wouldn't fit the chassis. Luckily my secondary machine was in an even bigger chassis, and it turns out it had mounting holes and rubber grommets already there to mount the Artic 3 Pro. So after stripping the 2 systems bare and swapping all of the components, booted up the new system with the Artic 3 Pro and checked the temps, and my basic idle temp is 26-28c, a good 10 degrees lower than the idle with the old water cooler. I haven't had a chance to stress it out with some video encoding yet, but I've already noticed that the heat spikes I was seeing previously seem to be gone.So in summary, I love the new CPU water cooler! I did run across one issue that had me worried when I first booted it up, and that was that there was a constant low humming noise that seemed to be coming from the unit. I'd read a couple of other people comments saying there was a low hum, but I figured it was a one off for them. Of course I like my rigs to be as quiet as possible, and since the PC sits right under my desk I knew this was going to drive me nuts. Luckily I was able to figure out the problem, which was the tubes from the CPU to the radiator are long and stiff enough that they were touching the side panel, and the humming sound was the noise from the liquid moving and being amplified by the metal door. Fixed this issue with a few zip ties to move the tubes slightly inward so they didn't contact the door, and now the system is as quiet as can be.I hope this review has been helpful, cheers.

I recently upgraded to the Arctic Liquid Freezer III 360mm AIO, and it’s easily one of the best cooling solutions I’ve used. Right away, I noticed the build quality—everything feels sturdy and well thought out. The pump design is unique compared to other AIOs, and I like that it comes with a small VRM fan built into the pump housing. It’s a smart addition that helps keep temps balanced across the board.Performance-wise, it’s been excellent. My CPU temps dropped significantly compared to my previous cooler, even under heavy gaming and rendering loads. The 360mm radiator with Arctic’s fans moves a ton of air while staying surprisingly quiet. Even when the fans ramp up, the noise is way lower than I expected for this level of cooling.Installation was pretty straightforward too. Arctic’s mounting system is simple, the tubing feels durable but flexible enough to work with, and I never felt like I had to force anything into place.A big plus for me is how clean it looks inside the case. The all-black design is sleek and minimal, so it doesn’t overpower the rest of my build. It feels like a performance-first product that doesn’t need flashy extras to stand out.Overall, the Liquid Freezer III 360 delivers on everything I wanted—excellent cooling, quiet operation, and reliable build quality. Arctic has a reputation for efficiency and value, and this AIO definitely lives up to that.

You can’t ask for a better AIO at that price. Thick radiator has more thermal mass than thin one, the redesigned fan blades push more air and quieter than the non pro version. All three fans were preinstalled and two cable choices; an all in one that goes to the cpu fan header or three separate cables to control pump speed, radiator fans speed and VRM fan speed separately. I found that the simple all in one cable worked very well. My recent builds were Intel Core Ultra 9 285k and AMD 9950x3d and stress test with Cinebench 2024 multi core at 100% for ten minutes temperature for the systems were 83 and 76 respectively. Of course in actual gaming the CPU will not run at 100% all the time and non gaming work hardly stress the CPU. This AIO is a winner at less than $100.
