Review: AMD MOUNTING NOT DIFFICULT LIKE SOME REVIEWS MENTION(READ BELOW!)Cools much better Noctua! - TL;DR: Mounts to AMD easier or as easy as a well known Noctua air cooler if you leave the mounting brackets on the motherboard loose before threading on the water block/pump to the brackets. Cooling performance is WAY above and beyond the best air coolers also while being able to lower the fan speed and run very quiet to dead silent while idling/webbrowsing (NO DISCERNIBLE CONSTANT PUMP NOISE - VERY QUIET). FIVE STAR FROM PLACING ORDER TO FINISHED BUILD! *Note: there was about a 4-5 second slight 'gurgling' sound during the initial powering on of the system after installing but appeared to be just some air bubbles in the pump that got pumped up to the radiator and that initial sound never returned after that initial 4-5 seconds of the initial power on after installing - it's been dead silent from then and thereafter multiple days of use even taking the side panel off and putting my ear up close to the side you still can't hear any discernible sound from any type of pump for those like me who like more silent builds and was worried about reading about pump noise in liquid cooling systems. Long Version: First things first, about the bad reviews/complaints about AMD mounting simply leave the two black mounting brackets that you attach to the motherboard fairly loose before attaching the water block/pump to the brackets and then it becomes easier than even installing a Noctua air cooler because on a Noctua air cooler you have to first remove the fan off of the heatsink after unboxing to tighten down the screws of the cooler to the mounting brackets and then reattach the fan back to the heatsink when done. So as long as you leave those brackets loose and tighten them down after attaching the water block, the ARCTIC Liquid Freezer III 420 becomes easier to install than even a Noctua air cooler! SO DON'T LET THE VARIOUS REVIEWS OF AMD INSTALLATION DIFFICULTY THWART YOU FROM BUYING, ITS REALLY SIMPLE AND EASY!!! Next, it cools MUCH better than a top of the line Noctua NH-D15S air cooler! And yes I even use the special AMD offset mounting brackets on the Noctua. I read a lot of people commenting in various places on the net from forums to Youtube comments that a top air cooler is comparable to a top liquid cooler, definitely not this 420mm one! On a 16 core Ryzen 9 9950x it dropped around 10 to 13c just sitting there idling and under full all core Prime95 CPU torture test even more since the Noctua would ramp up to my 85C thermal limit set in the bios (THIS IS EVEN UNDERVOLTING THE CPU!) and the ARCTIC Liquid Freezer III 420 would peak at 67c using the default out of the box fan curve in the bios of the MSI MAG X670E motherboard which was around similar sound output or lower than the Noctua but I set a custom fan curve in the bios to make the liquid cooler more dead silent and only gained 4c and peaked at 71c while under sustained prime 95 torture test. So now assuming that the CPU might of went higher than the 85c limit I had set in the bios on the Noctua air cooler, peak temp drop could of been even more than 18c! But even assuming that it didn't and 85c was what the Noctua peaked at, even with an undervolt, that's still a whopping 18c drop in temp out of the box! And the fact that you can spin the fans way down to near silent (including the case fans since you're not dropping CPU heat output back into the case) and only gain 4c from the out of the box fan curve to a more silent fan curve peaking at 71c during prime 95 torture test that's still a huge jump in performance from 85c of the Noctua while it throttled the fan to 100% noisey speed to the 14c drop running the fans of the ARCTIC Liquid Freezer III 420 at near silent! IDK about you, but I like a silent/quieter running sytem WHILE still performing dramatically better! Anyhow I was reluctant to purchase this as my first liquid cooler because desertcart gave warning that it was a frequently returned item. That had me worried that something might be inherently wrong with this model but I still wanted to experience liquid cooling for my first time and there was other glaring reviews across the net. I'm glad that I went with this one because the performance to price is phenomenal with lowering CPU temps while being quieter than and as cheap as top air cooling like Noctua and the installation on AMD was easier than even installing a well known Noctua air cooler as long as you leave the mounting brackets loose before threading on the screws of the water block/pump to the brackets. So if you were like me on the fence and reading reviews from people that the top air coolers are comparable to liquid cooling definitely not this 420 liquid cooler! It was nice to drop temps so much and get so much more quieter! Especially when you have a high core count higher end CPU like the Ryzen 9 9950X! When you read user reviews that say that the current AMD chips are a less power consuming and cooler running chip than say an Intel i9 14900k, don't assume that you're just going to get a high core count AMD Ryzen 9 9950X and it's going to be some easy to cool chip because it's a boiler in itself and I found that traditional but top notch air coolers like the Noctua had to get a little noisey to handle the high core count chips like the 9950X but the ARCTIC Liquid Freezer III 420 AIO Water Cooler makes easy work of it while being able to lower the fan speed noise on top of it. I love my silent running ARCTIC Liquid Freezer III 420 PC! Oh and, the case used was an Antec Flux Pro. Nothing from the out of the box settings of the Antec FLux Pro had to be tweaked to fit the ARCTIC Liquid Freezer III 420 to the top mount, not even having to lower the front three fans in the case. The Antec Flux Pro & ARCTIC Liquid Freezer III 420 make a perfect match and combo and work great together right out of the box! I ordered them both together from desertcart and they both came in 1 and 2 days (1 day for the cooler, and 2 days for the case)! 10 stars IMO!
Review: Keeps cpu cool? Yes, this is arctic we are talking about. - Nice AIO, really silent in general. Not for all pc case to be honest, but nothing some DIY cant handle!! Under full load, the 7900x3d x3d cores dont surpass 80c with 20c ambient. Quality of build is great, although i do feel like the seal between the fans and the radiator can be better, as it leaks a bit of air. Again, nothing some diy cant fix!!

## Features

- LGA1851 AND LGA1700 CONTACT FRAME: Improved contact pressure distribution through Intel mounting frame for efficient heat transfer, thanks to even CPU contact surface
- NATIVE AMD OFFSET MOUNTING: Optimized for the multi-die chiplet design of Ryzen processors - 5mm offset for optimal coverage of the CPU hotspot, resulting in more efficient heat transfer
- ACTIVE COOLING OF THE VOLTAGE CONVERTERS: PWM-controlled VRM fan that additionally cools components in the base area, such as voltage converters
- INTEGRATED CABLE MANAGEMENT: The PWM cables of the radiator fans are integrated into the jacket of the hoses, which means that only one visible cable is connected to the motherboard
- LIMITED COMPATIBILITY WITH A FEW MOTHERBOARDS: Oversized coolers on the M.2_1 slot can lead to compatibility problems. An overview and solution is available in the technical data, in the manual and on the manufacturer's website. Please use the compatibility check

### ⭐⭐⭐⭐⭐ Best AIO 420mm I have used. AMD users I have some advice for you
*by D***J on January 26, 2025*

As expected, Artic delivered with another great AIO. I have owned and reviewed several AIO coolers over the years. I will say, this is the best AIO I have found and it's way less than Corsair, ASUS, etc. I installed this on my Gigabyte X670E Aorus Pro X with a 9950X. AM5 installation is not difficult, but if you over tighten the left and right mounting brackets you will have problems. Install the left and right brackets, but do not fully tighten them down. Then install the pump unit. If you follow this method, installation is easy. Once the water pump unit is installed, go back and tighten everything up. I used the 3 cable option because I wanted to control the VRM fan via the BIOS. In my opinion, the 3 cable option is more desired vs the single cable. I don't want the VRM fan blasting when it is not needed. Overall, the 140mm fans are barely noticeable when I am using my PC for daily task. In gaming and work loads, this 420mm AIO easily keeps the 9950x under 70C. My case is a Corsair 7000D Airflow, so I had plenty of room to install this thick boy! I have no experience with the Arctic III's on Intel systems. So I cannot comment about that. For AMD AM5 this is the AIO to buy!
