ASUS ROG Strix LC II 120 ARGB all-in-one liquid CPU cooler with Aura Sync, Intel® LGA 1150/1151/1155/1156/1200/2066 and AMD AM4/TR4 support and a ROG 120 mm ARGB radiator fan

The ASUS ROG Ryujin III is hands down one of the best AIO coolers I’ve used. From the moment you unbox it, you can tell it’s built with quality in mind. The 3.5-inch LCD screen is a fantastic touch, allowing for real-time system monitoring or custom animations, which adds a unique aesthetic to any setup.In terms of performance, this cooler delivers. It keeps my CPU temps low, even under heavy loads, making it ideal for gaming and intensive workloads. The Noctua iPPC fans are an excellent choice—quiet yet incredibly effective at heat dissipation. Installation was straightforward, thanks to the clear instructions and well-designed mounting system.

Like so many PC enthusiasts I try to balance aesthetics and cooling performance to ensure that not only does my PC look appealing, but the cooling is adequate for whatever I throw at it.Personally the styling of this cooler was the first thing that caught my eye. I love a white /black colour scheme with another accent colour, in my case purple and this cooler compliments my setup so well.The installation was dead easy, the instructions were so simple to follow, and the whole unit felt very solid so it never felt like anything was going to be damaged during the installation. The finish of the paint on the radiator is superb. It has a beautiful sparkle to it and the whole thing was packaged so well that it would have to be extremely badly manhandled to be damaged in transit.The software is probably the biggest let down, but it's by no means a deal breaker. It occasionally will throw a fit and not want to do what it's told, but once you figure out its quirks it very straightforward to adjust your lighting exactly as required.I will run some stress tests and update the review with temperatures but given the case and lack of airflow, I have the fans as intakes pulling air through the radiator from the minimal airflow slots on the front of the case and it's absolutely fine handling a Ryzen 2700X at well over 4GHz without breaking a sweat.The main thing about the cooler is it allows me to keep my CPU cool without having loads of fans in the case as I like a minimalist appearance and less fans is one way to achieve that, yet it still passes air over the other components in the rig to ensure nothing overheats.I am content with the price as it's a stunning cooler visually and it does it's job without sounding like a hair dryer on full power. I never review anything straight away, but two months down the line it's been trouble free and I hope it continues that way for the duration of its life in my computer and should I upgrade my CPU down the line I know this will be more than capable of handling AMD's latest offerings.

I’ve been using the ROG Strix Ryujin III 360 AIO for a while now, and I’m genuinely impressed with the performance. One of the biggest things I noticed right away was the drop in CPU temperatures—this cooler is no joke. Under load, my temps are significantly lower compared to my previous setup, which gives me way more confidence during intense gaming sessions or heavy workloads.The built-in LCD screen is a great touch too. It’s not just for looks—it’s super useful for keeping an eye on system temps and performance in real-time. Being able to glance over and instantly see how my PC is doing without needing extra software is a huge plus.Overall, this AIO looks great, performs even better, and the added features like the screen just make it feel premium. Definitely worth it if you want high-end cooling with a bit of flair.

I purchased this cooler over some of the more cheaper ones available as the others had reviews mentioning leaks and inconsistent cooling. I am glad I went with this unit, its well made and put together to high standards.I use it to cool a Ryzen 5 which was running hot on air cooling as my case (a Lian Li TU150) has poor airflow and limited space being a MiniATX build. I experimented with the radiator placement and found that mounting it as a front intake worked best. My temps on air were high 80s under load and now they are 65 on average.The pump is virtually silent even on full power and the fan is powerful so doesn’t need to run fast to keep things cool – I have the pump set at around 60% power and the fan lower, regardless of load, and I find this is a perfect balance of cooling and noise levels.One thing I would recommend is to use your own thermal paste – the pre applied paste on the water block was dry and unusable so it has to be cleaned off and fresh paste applied.Really happy with the RGBs too, which are recognised by my motherboard and sync with the other RGB LEDs in the case.Highly recommended purchase if you need a compact cooling solution that is quieter than air coolers.

Amazing piece of kit. Simple to install and keeps my 5800X wonderfully cool. Very handy too that it comes with a Zen 5 bracket, making the next CPU a breeze by not having to buy another unit.

The media could not be loaded. The AIO is very quiet and temperatures are extremely good. CPU doesn’t go above 60 degrees in heavy gaming and in Cinebench stress test it never got above 74. Keep in mind I have a i9 10900kf OCed to 5.1ghz which is a very power hungry cpu. The Noctua fans are also of impeccable quality and run very quietly. I bought this when it was around 30% off so from £409 to £270ish but to be honest £270 should probably be the original price because no AIO is worth £409, definitely do not buy this at full price.Overall it is a nice AIO that preforms as it should but if you don’t really have a power hungry or high end cpu then I simply recommend you get a more cost effective AIO as this is really something you would buy once you are fully content with all your other pc parts.

Really like the look and quality of this AIO. Wasn't sure on the pixel aesthetic at first but it's grown on me. CPU temps have been great so far as well. Happy with my purchase so far!
