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.

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!

Design: it has the signature ROG Logo which I personally love, it also supports aura sync with is great to have paired with my other ROG products Cooling Capacity: the cooling power for this AIO is tremendously great, not once have I ran into any overheating even while gaming with high processing power. Fan Speed: the cooling fans are able to to be customized in the armoury crate to to suit your specifications whether you prefer a nice quiet fan or turbo for faster and better cooling. Price: overall the price is worth the quality of the product, it's very user friendly to install. This was my first time building a PC and I was so worried about installing it correctly but with this product it was such a breeze that anyone could do it! If I were to have any complaints it would just be that the metal cooling panel behind the fans get bent relatively easy but still works great overall.

Outstanding CPU AIO, very easy installation and set up, super quiet, and looks great. CPU temps stay down, even when playing more demanding games. I would definitely say this is the best cooler for its price point.

I opted to make a new build for XMas and used this AIO. I've always gone air-cooled in the past and since I was going small form factor this time around I figured that I'd go AIO - mostly for space considerations but a bit for quiet as well. Cools an AMD 78003D like a champ. Nice and quiet - can hardly even hear the pump (my hearing aids are in for repair, so I admit that I'll need to reassess this in a couple weeks.) Installed without too much trouble - enough length of tubing to accommodate any positioning I could think of for this case, but would work well with other case sizes, too. If I wasn't building SFF I'd probably go with the 360mm version, all considered. Pre-applied paste seems to have been up to the task - it was a thin silkscreen layer that looked dry on-sight and to a light touch, but was sufficient (and not dry at all - just a bit stiff). Had to re-position the pump and block and noticed good smooshy coverage of the CPU. Box had everything a boy could need in there - a variety of different standoffs for AMD4-5/INTEL setup, a mess of screws and a pretty good installation guide. Anyhow, the real bugbear was the fans - one of the fans, to be precise. It had bad bearings and sounded like a rattletrap the moment I did my check for post. It was soooo obvious and even a finger-spin would set it off. I swapped out both fans for a pair of 3-wire scrap coolermasters I had laying around from an old machine. Problem solved, done-and-dusted. Not sure how important the 4-wire (they're in a ribbon) stock fans are, but 3-wire seemed to throttle up and back as needed. Whatever magic conversation the pump is having with the CPU over the USB header, the fans seem to be getting the right message. Conclusion: Don't trust the stock fans on these things. Buy nice fans... you don't have to go Noctua, but get something decent and quiet. ASUS makes a lot of really good stuff, but whoever they get fans from is wicked bad at running the most basic tests. I sorta wish that I'd looked around for a version that didn't have fans so that I'd just have to buy a pair of my choice and it would not have been an issue. Also, when screwing the radiator snug up to the case, I noticed that the threaded ends of some of the mounting screws did dent the radiator vanes a bit - no punctures (thank goodness) but if you're sensitive to that kind of thing just get some thin rubber grommets to achieve enough space to avoid interference. Good coooler, happy with the result.
