Rank #2 in Best AIO CPU Cooler 2026: 10 Ranked, and the Spec Numbers That Disagree
ARCTIC Liquid Freezer III Pro 360 (non-RGB)
Price and rating as shown on Amazon when we collected them. Both change.
The ARCTIC Liquid Freezer III Pro 360 is the runner-up in this guide: a 360 mm liquid cooler with a 38 mm radiator, three 120 mm P12 PRO fans, a PWM pump and a small PWM fan over the voltage regulators. It is listed at £67.49, holds a 4.3 average from 2,380 ratings, and carries a six-year warranty.
Its listing is the odd one out in a quieter way. Where other 360 mm coolers here quote one noise figure in the bullets and print a different one in the spec table, ARCTIC states no dBA number anywhere — there is nothing to disagree with. The power field gives 3.96 watts at 12 volts, a real current draw rather than a TDP dropped into the wrong box, and it sits inside the 1.8 W to 16 W band the other coolers in this guide occupy. The airflow field is a single 77 CFM alongside a 3000 RPM maximum, and nothing on the page says whether that airflow is one fan or all three. Everything on this page comes from the Amazon listing for this cooler, not from testing we carried out ourselves.
How those 2,380 ratings break down
An average hides its own shape. This is the spread behind the 4.3 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Replaced my Ryujin two and Ryujin one, with two of these they are very very cheap but they only goes as far as what you pay for as the build quality and build quality is fantastic. The pipes are large.The fans are super quiet and it even has a VRM fan (this was one of the main factors of me choosing these callers as my previous callers both had a VRM fan), one of these went onto my ROG Crosshair Hero VIII ATX motherboard and the other went onto my ROG Strix Mini ITX motherboard, both with no issues (I did have to flip the pump head 180° on my Strix purely because the bottom failed on the raised M.2 heat sync, but the manual says you can mount them this way and the temperatures speak for themselves), I even quite like the way the mounting is as it offsets the copper pad so that the hotspots of the Ryzen 9 5950X's that I have mount directly in the middle of the plate leving a small piece of the CPU uncovered (this is by design and tells you this in the instructions as well), I will be honest. I was very dubious to start with but I'm running both and the temperatures a hovering around 30°C my previous coolers never got any lower than 41°C.The appearance may not be for everyone, no they don't have LEDs and no they don't have screens but they do look good. I do like the design of the pump head looks a little little like an aircraft turbine and if you want raw great quality cooling you can't go wrong and for the price it's almost as if you've stolen them!I would fully recommend these for any build, including Intel CPUs as they come with an Intel mount as well!”
Verified purchase“I didn't know cooling could be this good! This thing keeps my i9-13900k considerable cooler that my old Gallahad 360, combine it with some custom fan curves and my computer runs cool and quiet during light work and a bit loud but low temps under full sustained load. Really nice to be able to get one with lots of flashing LEDs as well!Install is easy enough, the only tricky bit is you might want an extra hand to hold the frame on the back of the mobo whilst you latch the first screw. Instructions are clear and easy to follow. Nice that it comes with plenty of very good thermal compound.It's a thicker radiator than normal, so just double check clearance before you buy. VRM cooler has a noticeable effect which is great. It's one of the most affordable 360 AIO's and clearly one of the best.”
