    • Great Performance and Looks
Style: Gen II (ARGB) Size: 240mm
I've been using this aio for a few years now, and it’s been excellent. It keeps my CPU temperatures low during gaming and multitasking, and the rgb adds a clean touch to my build. What I like: Excellent cooling performance – handles high temps with ease Quiet operation – barely noticeable even under load Sharp ARGB lighting – looks great and syncs perfectly with Aura Sync Easy installation – clear instructions and solid mounting hardware Sleek design – premium build that fits well in most mid to full-sized cases If you're after a balance of performance, aesthetics, and ease of use, this AIO cooler is a solid pick. ... show more

    • Fantastic AIO Cooler – Easy Installation and Great Performance!
Style: Gen II Size: 360mm
I recently upgraded to the ASUS ROG Strix LC II 360 AIO Liquid CPU Cooler, and I am extremely impressed! The installation process was a breeze, thanks to the well-designed mounting system and clear instructions. It fit perfectly in my case and supports a wide range of Intel and AMD sockets, which is a big plus. In terms of performance, this cooler is outstanding! My CPU temperatures have dropped significantly, even under heavy loads. The triple 120mm PWM fans are quiet! If you're looking for a reliable, high-performing liquid cooler that's easy to install, I highly recommend the ASUS ROG Strix LC II 360. It delivers both in cooling efficiency and style! ... show more

    • Works for LG1700; fantastic performance
Style: Gen II (ARGB) Size: 240mm
There are surprisingly not a lot of CPU liquid coolers that have LGA1700 compatible mounts. Yes, it's only $8-$10 for the mount separately, but I don't care for that. I want it all included. I just want to turn off my brain, install it, and move on with my life. - Easy to install. Just follow the instructions. And god forbid you have problems - just youtube it. - All provided screws are good quality. Nothing alarming. Just don't be bad. There are a lot of subpar CPU coolers out there (don't waste your time on stock or cheap ones; the radiator, pump, something will die). - Nice LEDs - not that it really matters to me. - Excellent performance - I was able to overclock my 11700k to 4.1GHz and still get 60C peak during gaming. This cooler gives me a false sense of being able to 5.0Ghz (I might get frisky one night with dear Strix II) At base 3.6GHZ - the peak I've seen is 55C. All very good and respectable temperatures. - Excellent fans - relatively efficient and solid airflow. I have a compact case, so the quality fans help keep the GPU cool as well. $125 - $150 is the sweetspot for a high performance cooler, without breaking the bank. I wouldn't waste my time or risk something below $100. Not biased, just have to look at your PC's life with your investment. And this is a good one. Fantastic CPU cooler. It's a high performance cooler that has the bells and whistles (if you so desire; I could care less though). I wanted something that wasn't going to give me a headache and to be worry free for at least 3 years. The stock cooler with my PC was a nightmare. Thank you, Asus, as per usual. ... show more

Good AIO cooler, does a good job at keeping the cpu cool even under a heavy load, haven’t had to worry about over heating. Assembly was easy and lighting on the fans are fairly bright

    • It's SOOO Pretty!
Style: Gen III (ARGB, LCD) Size: 360mm
Review Image by Kyle Kyle
I always did CPU fans in the past, and this was my first ever build using a liquid cooler for my CPU, and it honestly was much easier than I expected. For starters, I love the fact I can make the image a custom image and still see my CPU and GPU temps. Second, it's beautifully quiet which is awesome for me because a mic picks anything up over XLR so less work on my backend if you do videos. The size is perfect and I love that it fits a full-size case perfectly. Lastly, it just looks so beautiful! I love the colors on the fans. It is so calm and you can make it look however you want. The ASUS app works easily and even better makes it easy to update drivers without always having to individually search for each one. Love this product and so glad I tried liquid cooled finally. I'm honestly never going back to the old cooling ways. ... show more
