With Ryzen 5 5600x
Stock cooler: 55 idle 90+ in stress test (exporting large video files with davinci resolve etc)
Arctic liquid ii 240: 32 idle and I couldn't exceed 64 degrees no matter how many things I ran. Exporting, 10 chrome tabs, Fortnite, league, genshin, and cpuz stress tester all running simultaneously and it didn't go over 64, I couldn't believe my eyes. With the stock cooler, I reached 82-83 only with Fortnite.

On the downside, which I will overlook because despite all the curses I threw while trying to install it, it blew away my expectations.
No instructions at all. Just a qr code that personally led me to a dead link. I had to search on reddit for the instructions for am4 placement. Not that they helped of course. Because the instructions for some reason are different from the video of arctic itself that shows you how to install it. Huge pain for 3 whole hours for no reason. At first, following the instructions faithfully, the cooler wouldn't fit on the motherboard so I had to start over from scratch. After watching YouTube, I managed, but the standoffs were a nightmare to screw in with the cooler on top so as not to mess up with the thermal paste, which is included. Huge frustration with the standoffs and screws, and the fact that they came out with the slightest touch unless you screw them in well. Also, the packaging has let's say 3 bags of screws that look the same. Be careful not to open them all together because then you won't be able to tell them apart and you'll have to start over 4 times like me. Of course, it was my first time installing something like this and I improvised a lot, but apart from the installation and the fact that it literally drained my soul, it's worth the money. Someone who knows what they're doing will likely have a better experience than me.

Also, on the site it lists the compatible motherboards, but mine for example, ASRock b550 pro 4, is not listed. It doesn't list any b550 precisely, and my soul was crushed when I read that. I want to hope that it fits in every am4 Mobo, but I would recommend researching it thoroughly first to avoid any problems. That's all
