Arctic Liquid Freezer III Pro 240 A-RGB - 240 mm AIO CPU Cooler, Water Cooling, 38 mm Radiator

The ARCTIC Liquid Freezer III 240 A-RGB delivers outstanding cooling performance with very low noise. The PWM-controlled pump and fans keep temperatures under control even under heavy loads, while staying quiet during normal use. Installation is straightforward, and the included LGA1851/LGA1700 contact frame is a great bonus for improved CPU contact. The white A-RGB design looks clean and modern, making it a perfect match for themed builds. Reliable, efficient, and great value for a 240mm AIO.

Lowered my idle temps from from 38c to 36c. However, the biggest change is at load, benchmarking my CPU @ 100% load for 15 mins my previous AIO(Coolermaster ML240) I went from 72.4c down to 68.2c. I will say at max fan speed it is rather loud in my normally very quiet system. Modifying fan curves to not ramp up to 100% so quickly resolved most of this. Also, I am running a 7800x3D, which I believe this cooler is more designed(meaning AMD in general) for, and the ease of installation and performance vs Intel is proof of that. Also, CHECK YOUR CASE AND COMPONENTS FOR CLEARANCE! This radiator and fan combo is around 12mm thicker than most AIOs on the market. It fit perfectly in my Corsair 4000D case with my Asus ROG Strix B650e-e motherboard. I could probably have gone for the 360mm version of this but some reviews show that one sometimes gets worse performance than the 240mm version, so just a word of caution there. Final verdict: This is a must buy for the AM5 platform. Great build quality, performance and at an incomparable price!

Great product, runs quiet, easy install besides header clearances on MB (not the product's fault, my case needed an extra 1/2" clearance to make it a kid-friendly install). LEDs are bright. I wish the hoses had integrated cable management, but not going to detract stars since it was not a selling point. Performance is great, dropped CPU temp by 30* C over stock air cooler during stress test comparison. Stock air cooler experienced thermal throttling, this AIO never exceeded 65* C on Ryzen 9 3900 chip. I setup BIOS to have pump to run flat 100% all time, and fans on a curve based on CPU temp. Besides the stress test, fans rarely spool up, and even more rarely reach 80% speed. 100% would recommend to anyone looking to purchase a cheap AIO.

Very nice RGB, noise, fans with good performance with my AMD 5800x3D. Install was not bad until applying the cooler to the processor itself. It was a nightmare to get the plate down and took quite a bit of force compared to other AIOs.
