Full description and specifications

The Asus ROG Ryujin III 360 ARGB AIO Liquid CPU Cooler is engineered to redefine thermal performance and visual immersion for high-performance gaming builds and professional systems. Built with premium components and advanced cooling innovations, the Asus ROG Ryujin III Liquid Cooler delivers superior heat dissipation and unmatched personalisation.

At the heart of the cooler is the latest 8th-generation Asetek pump, driven by a 3-phase motor that delivers high flow rates with reduced impedance and minimal operational noise. This ensures reliable thermal control even under heavy CPU loads. Enhancing the cooling architecture further is an embedded fan with a new ring-shaped frame and optimised airflow channels, specifically designed to target the VRM area for enhanced motherboard longevity.

The cooler features a robust 399.5 mm aluminium radiator paired with three 120 mm ROG magnetic daisy-chainable ARGB fans. Each fan operates between 600 to 2200 RPM, delivering up to 70.07 CFM of airflow with a static pressure of 3.88 mmH₂O. These fans are equipped with Gen 2 ARGB LEDs, enabling dynamic lighting effects that can be fully customised through Armoury Crate.

A standout feature of the ASUS ROG Ryujin III 360 ARGB AIO Liquid CPU Cooler is its integrated 3.5-inch full-colour LCD screen. With double the storage of previous iterations, users can showcase system stats, custom animations, or logos directly on the CPU block. The display, fans, and pump can all be finely tuned via Armoury Crate for complete control and synchronisation.

Supporting the latest AMD AM5/AM4 and Intel LGA 1851/1700/1200/115x sockets, this cooler is future-ready and highly versatile. It also includes a free one-year AIDA64 Extreme license for advanced system monitoring.

Questions

Before you buy

Will this radiator fit my case?
It is a 360mm radiator. Your case needs a mounting position that takes that size - usually the front or the top - with enough clearance behind it for the fans and the radiator thickness. Every case we sell lists its supported radiator sizes under Specifications.
Does it fit my processor?
The brackets in the box cover AM4, AM5, LGA1200, LGA1700, LGA1851. If your socket is on that list, everything needed to mount it is included.
Is it in stock, and when will it ship?
Yes - this one is in stock. Order before 12:00 on a working day and it ships the same day; after that it goes out the next working day. We are open 09:00 to 16:30, Monday to Friday, so an order placed over a weekend or a public holiday ships on the next working day.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
