ARCTIC Liquid Freezer III 360 - CPU AIO Water Cooler, Water Cooling PC, Intel & AMD, Efficient PWM-Controlled Pump, Fan: 200–1800 RPM, LGA1851 and LGA1700 Contact Frame - Black

I had just completed a new build but retained my older Liquid Freezer II 360 thinking it had been so solid of a cooler it should be fine. However while the build was stable I was idling around 55C, and I was getting far more pump noise than I had been accustomed to. CPU from older system was a 5600X and new one is a 7800X3D, so I figured it was probably a good idea to upgrade the cooler.Absolutely fantastic performance with the new unit. Idling at a cool 35C, MOSFETs are at 29C while I type this, and the installation was straightforward and to the point. Slight difficulty with installing the block on the motherboard trying to get the screws to thread properly with the leaf spring providing constant tension, but that was the only issue I ran into. All of the instructions and package labeling were perfectly clear. Super quiet but excellent airflow around the CPU socket with the easily-detached fan. 100% can recommend.

Great product that doesn’t need no advertisement. Great quality and quiet operations. Keeps the temps cool. Easy install! No issues whatsoever so ever! Don’t listen to those who say the installation process could be challenging. Just 2 screws to screw onto the AMD bracket - can’t be easier than that. Simple cable management which is straight forward and provides good clean look. Can’t go wrong with this unit. Be mindful of your case compatibility as the radiator is THICK and might interfere with your motherboard!

ARCTIC Liquid Freezer III 360 AIO - I installed this on my nephews new PC we were building with a Ryzen 7900X. It works great and runs very quiet compare to the Thermalright Peerless Assassin 120 SE that I recently installed in my sons PC it was also a lot more delicate and difficult to install. The instructions are a guided website that is mostly pictures which as fine for 90% but in my opinion really needed a note to explain what to do with the VRM cable. It turns out it was for a VRM cooling fan and plugged into a standard fan header. The instructions for mounting the water block look as simple as put it in place and screw it down. It took us 45 minutes and smeared the thermal paste all over the place (I highly recommend a thermal paste guard/contact frame). The issue is the screws barely protrude and the spring mechanism points the slightly outward so getting 1 of them to just catch was hard enough but getting the 2nd 1 to catch took an uncomfortable amount of force pushing down on the block and screw to angle it correctly coupled with a lot of luck. I know this is to get even force on the block once it is installed but was so much more difficult than simple spring loaded screws like the Peerless Assassin had. The radiator took time due to a fan direction and getting around the case limitations but over all installed easily enough. the problem is the radiator fins are as soft as clay and get dinged up if ANYTHING even looked at them funny. I think the dings were mostly cosmetic and invisible behind the fans the front grill of the case but I was still annoyed and the Peerless Assassin finds were not nearly as fragile. in summary, the price was great (I payed $90 - wish I had spent another $20 for RGB), the installation was frustrating, but now that it is done I am quite happy because this thing is really quiet and the CPU stays cool. I expect my nephews PC will keep him gaming for years.
