Introduction

Can we call this the “entry-level” AIO cooler from ROG? Well, it is the more affordable among the two recently launched coolers… In case you missed it, we have reviewed the higher end of the Republic of Gamers’ AIO coolers, the ROG Ryujin, and it somewhat let us down with its unimpressive performance for its price. Will the ROG Ryuo 240 buck the trend and offer better performance at a more affordable price? Let’s find out.

Unboxing

Packaging wise, ASUS did an amazing job with the ROG Ryuo 240. A red and black theme, with the text finished in fancy chrome. Great looking stuff. Just like it’s bigger brother.

Lifting the cover reveals the typical overkill elements that ROG is well known for. There’s a flap that does nothing other than showcase the ROG logo. And of course, the rest of the contents.

The contents of the package are very comprehensive, and you get everything you need to install the ROG Ryuo 240 on any platform you want. You can even install it on AMD TR4!

The ROG Ryuo 240 looks a lot more like a conventional AIO cooler, with its circular pump. Of course we won’t forget that the flat surface at the top is home to the OLED display in this pump. Not so conventional is the huge mess of cables running out of it.

There is even a USB port on the side, which needs a pretty standard looking microUSB. Not exactly the best strategy to add some I/O to an AIO, when it’s already has so many cables snaking out.

Moving on from the cables, we take a look at the coldplate. There is no mirror shine here, but it is even enough, and there’s pre-applied thermal paste. Just like the ROG Ryujin.

The thickness of the radiator is also pretty standard, so most cases which fit a 240mm radiator will fit the ROG Ryuo 240.

ASUS decided to bundle the higher end ROG Ryujin with Noctua iPPC fans, while the ROG Ryuo 240 comes with ROG-designed fans. Well to be honest, they don’t look like a downgrade at all, because these fans look awesome! There are no vibration dampening material anywhere though.

Once you connect all the cables, you will be feted to the OLED display and also some addressable RGB lighting along the circumference of the cooler. The OLED panel is much closer to the surface in the ROG Ryuo 240 than the in the ROG Ryujin, so the display actually looks more vibrant here.

The same can’t be said about the RGB lighting though. Despite the fact that the LEDs themselves are pretty bright, the fact that so little is visible when you look at the cooler from the front is quite disappointing.

As with the ROG Ryujin 240, ASUS did not publish any specifications for the pump, so we do not know what’s the life expectancy nor the noise level of the pump here. Upon testing we did find that it spools up to around 2700 rpm, and runs quite quietly. But given the rather high noise levels of the fans, anything else sounds quiet by comparison.

Speaking of the fans, unlike the ROG Ryujin which came with Noctua’s fans, the ROG Ryuo 240 here comes with fans designed by ROG themselves. It runs at 2500 rpm, which is faster than most of the fans bundled with recent AIO coolers we have tested. It also offers impressive static pressure at 5.0 mmHgH2O, which is what you want to push air through the fins of a radiator.

Testing Methodology

Our Intel Core i7-5820K CPU will be clocked at 4.125 GHz, with a Vcore of 1.11V set in the BIOS. The thermal paste of choice will be the MasterGel Maker, sponsored by Cooler Master. To test the performance of CPU coolers, we run LinX 0.6.5 for 40 minutes, with a problem size of 23118. The fans (and pumps, if available) will run at maximum speed to gauge maximal performance. Ambient temperatures are fixed to 25°C, in an air-conditioned room. Noise levels are recorded approximately 50cm away from the bench rig.
