ARCTIC Liquid Freezer III 240 - Water Cooling PC, All-in-One CPU AIO Water Cooler, Intel & AMD compatible, efficient PWM-controlled pump, fan: 200-1800 rpm, LGA1851 and LGA1700 Contact Frame - Black

Just got my hands on one of these and, after a long time away from building my own custom built liquid cooled machines, this is a game changer.If you not into all that LED RGB Rubbish, and want a quiet, efficient and economical AIO Cooler for your CPU, this is the one to get. The version I got was Rev4 (The Latest), which has a few updates from the original ones.Couple of tips here to take note of:1. If you are installing this into a case you have already got, the radiator on this one is thick (38mm), plus add on 25mm for the fan. So this will stick out a lot, but if you bought the iONZ Kuro W07 Pro Gamer Full ATX Gaming Case also from Amazon, for a mere £50, it will fit in there like a dream and no issues with RAM clearance at all.2. Also, if you installing into a case you already have, install the radiator first before the block. The instructions say to do the block first, but that's a real PITA. Personally I would install the radiator first even on a new build (after MB has gone in).3. Read the instructions thoroughly and take note of the pictures. There are some steps missing, but the pictures fill in the gaps. Do EXACTLY what the instructions tell you. And take your time to get it right. Took me a total of 30 minutes to do it all.4. I did not use the thermal paste that it came with as I already had some Kryonaut thermal grizzly to hand (which is my go to thermal paste for anything really).5. The supplied washers for screwing in the radiator to the top of my case made the screw heads stick out too much that prevented me putting the dust shield back on. The slots on the case were narrow enough to forgo the washers. Now sits all nice and flush.The VRM cooler fan on this is such a great idea. There is no noise from this at all, and definitely keeps them cooled. Overall it is VERY quiet, and having the added PWM functionality throttles the fans and pump when needed.Have gone from a wraith type cooler with copper pipes and big fins to this. I went from and idle temp on a Ryzen 5600X of about 40-45C to about 25-28C. And at full load I don't think I have seen it go much above 55-60C

Using this with my stock Ryzen 7 5700x3D and I don't go above 65/70c under heavy load, so good cooling. Really quiet. Looks sleek and visually pleasing in my case (NZXT H9 Flow). Slightly awkward installation (for AM4 anyway) when mounting the washers/backplate. Nothing crazy difficult, just be patient and you'll get it. They have installation videos on their Youtube page. Handy fan splitters for all-in-one or individual control over pump/fans etc. Overall really good cooling and quality for the cost. Will be using Arctic again in the future!

Arctic is a household name in the computing industry. They've been around forever, and unlike many of their competitors, they rely upon their solid reputation for most of their marketing. They don't often do flashy, RGB ridden products. You get solid performance at a great value and, often, it's even better than the competition at higher prices.This 240mm AIO is exactly that. You get cooling performance that is as good as, or better than the moderately more expensive competition (*cough* Kraken), it's whisper quiet and a breeze to install (even in the CM NR200P which isn't ideal for this type of pump block). For my Ryzen 3900X this AIO keeps my CPU much cooler than both the NH-U12A and the Dark Rock Pro 4 in a Meshify C case (though this is likely due to being able to get fresh air directly for the CPU by side-mounting the radiator. More importantly, fluctuations are far less apparent with an AIO over air cooling, something that did bug me a bit with my previous setup because of the fans ramping up and down at regular intervals. Even at full load this thing is really quiet, though I'm using aftermarket Noctua NF-A12x25 fans on the radiator. However, I am using Arctic's P12 Slim fans on the bottom for intake and they're also whisper quiet.In summary, arctic has delivered everything you need in an AIO - form, function and value. The extra fan on the pump for VRM cooling is an added bonus in my build (using the Gigabyte B550I AORUS PRO AX so VRM temps aren't much of an issue anyway).If you're looking to upgrade from air cooling, this is a no-brainer. It's cheaper than some of the bulkier options and delivers superior performance if you can deliver fresh air to the radiator. Even at 240mm! I'm sure the same holds for the 280mm and larger.
