AI Verdict
This is a 178 micro-cooling fin, copper alloy water block with a 3.5-inch 60 FPS LCD display and an embedded VRM fan, for builders prioritizing aesthetics and VRM cooling in a custom loop.
This water block is a situational fit because its 3.5-inch LCD display and embedded VRM fan offer unique aesthetic and motherboard cooling benefits. However, its reported high flow restriction and lack of an integrated pump mean it's only suitable for users who understand and can mitigate these specific custom loop challenges.
If you need a water block with lower flow restriction or an integrated liquid temperature sensor, look for models specifically designed for high flow or with dedicated sensor ports.

Pros
- Asetek-powered water block with 178 micro-cooling fins and a copper alloy cold plate enables rapid CPU cooling.
- 3.5-inch full-color LCD display with 60 FPS refresh rate and 24-bit color renders vivid visuals and supports custom GIFs up to 32MB and 2000 frames.
- Embedded Axial-tech VRM fan reduces motherboard VRM temperatures by up to 35°C.
- Bundled all-copper ROG fittings ensure seamless water flow and elevate the custom loop's appearance.
- Extensive compatibility with Intel LGA 1700, 1200, 115X and AMD AM5, AM4 motherboard platforms.
Cons
- Users report significant water flow restriction, with flow rates dropping from 400 L/hr to less than 100 L/hr, or 100 L/hr to 40-50 L/hr, after installation.
- The block is physically tall, potentially causing obstruction in custom cooling loops, especially with vertical GPU mounts.
- LCD display customization is limited to 2 themes for system readings, and it lacks a built-in liquid temperature sensor.
- Screws included for mounting may be too long, potentially damaging the radiator.
- The product does not include an integrated pump, requiring a separate pump in the custom loop.
Dimension Scores
The Asetek-powered block with 178 micro-cooling fins and copper cold plate provides effective CPU cooling, but reported high flow restriction can hinder overall loop efficiency.
The embedded Axial-tech VRM fan operates at up to 5100 RPM, which can generate noticeable noise, though its impact on VRM temperatures is significant.
It features an Asetek-powered block, copper cold plate, and all-copper ROG fittings, indicating a premium material selection, though some users noted the construction felt 'cheap-ish' for the price.
The block itself doesn't have extensive cable management features, and its large size can complicate tube routing in custom loops.
Best For
- Custom PC builds where visual aesthetics and a customizable CPU block display are primary considerations.
- Users with high-end CPUs and motherboards who want to actively cool VRMs with an integrated fan.
- Enthusiasts building open-loop water-cooling systems who already have a separate pump and reservoir.
Not Recommended For
- Budget-conscious builders seeking maximum cooling performance per dollar.
- Users who prioritize minimal flow restriction in their custom water-cooling loop.
- Anyone expecting an all-in-one solution with an integrated pump.
Watch Out For
- Water flow restriction can be severe; one user reported flow dropping from 250 L/hr to under 90 L/hr after installing this block.
- The block's height can create clearance issues, making tube routing difficult, especially with vertically mounted GPUs.
- The LCD display has limited functionality, offering only two themes for system readings and no direct liquid temperature sensor.
- Included mounting screws for the radiator might be too long, with one user noting they were 8mm and caused damage.
- Armoury Crate software can be buggy; some users reported ARGB connectors flickering and not appearing in the software.

What Buyers Say
The most surprising feedback is the significant water flow restriction reported by multiple users, with flow rates dropping dramatically after installing this block. Many buyers are drawn to the 3.5-inch LCD display for its aesthetic appeal and customization, but some find its functionality limited, especially with only two themes for system readings and no direct liquid temperature display. The embedded VRM fan is consistently praised for its effectiveness in reducing motherboard temperatures. However, the physical size of the block can make custom loop routing challenging, and some users encountered issues with the included mounting screws being too long.
“Man, this thing looks sick with the screen, but my flow meter went from like 250 to 90 L/hr, what gives? And those screws almost poked my rad! Still, my VRMs are chillin'.”
Common Praise
- The 3.5-inch full-color LCD display offers vibrant visuals and extensive customization with GIFs and system stats.
- The embedded Axial-tech VRM fan effectively reduces motherboard VRM temperatures by up to 35°C.
- The Asetek-powered water block with 178 micro-cooling fins provides efficient CPU cooling.
- The all-copper ROG fittings enhance the aesthetic appeal of a custom water-cooling loop.
- The wide compatibility with Intel LGA 1700/1200/115X and AMD AM5/AM4 sockets is convenient.
Common Complaints
- Significant water flow restriction, with reported flow rates as low as 40-50 L/hr after installation.
- The block's height can obstruct custom loop tubing, especially with vertical GPU mounts.
- LCD display has limited themes for system readings and lacks a built-in liquid temperature sensor.
- Mounting screws included for the radiator can be too long, causing potential damage.
- Armoury Crate software can be buggy, leading to ARGB flickering or devices not appearing.
Ownership Tips
- You'll definitely need a separate liquid temperature sensor if you want to monitor your loop's water temp on the display.
- Be prepared to source shorter mounting screws for your radiator, as the included ones might be too long.
- Plan your custom loop tubing carefully, as the block's height can make routing around a vertical GPU tricky.
- Expect to spend some time tweaking Armoury Crate for the LCD display and ARGB, as it can be finicky.
- The VRM fan is audible at higher RPMs, but it genuinely helps keep motherboard temperatures down.
Frequently Asked Questions
Does this water block include a pump?
No, the ASUS ROG RYUJIN III WB is a water block only and does not include an integrated pump. You will need a separate pump and reservoir for your custom water-cooling loop.
Can the LCD display show liquid temperature?
The water block itself does not have a built-in liquid temperature sensor to display on the LCD. You would need to integrate a separate liquid temperature sensor into your custom loop for this functionality.
What kind of customization options does the LCD display offer?
The 3.5-inch LCD can display hardware information like CPU temperatures and frequencies, fan speeds, or water flow. It also supports pre-made ROG animations and custom GIFs up to 32MB and 2000 frames.
Is the VRM fan effective?
Yes, the embedded Axial-tech fan is designed to increase airflow around the motherboard VRMs, with ASUS reporting a reduction in VRM temperatures by up to 35°C.
Is this compatible with my CPU socket?
It is compatible with a wide range of Intel sockets (LGA 1700, 1200, 115X) and AMD sockets (AM5, AM4).
Buying Guide
When you're looking at a CPU water block like this, you're essentially buying the part that sits directly on your processor to transfer heat into your liquid cooling loop. It doesn't do the cooling all by itself; it's just one piece of a larger custom system that includes a pump, reservoir, radiator, and tubing. The big deal here is the display and the VRM fan, which are extra features beyond just cooling your CPU. You need to make sure your other components can handle the flow restriction this block might introduce.
Asetek Copper Cold Plate with 178 Micro-Cooling Fins
This is the part that touches your CPU. More fins and a copper plate mean more surface area to pull heat away from your processor quickly, like a super-efficient sponge soaking up heat.
3.5-inch Full Color LCD Display (60 FPS)
This is your PC's personal billboard. It lets you show off system stats, custom images, or GIFs directly on your CPU block. Think of it as a tiny, dynamic window into your PC's soul, running as smoothly as a short video clip.
Embedded VRM Fan
VRMs (Voltage Regulator Modules) on your motherboard get hot, especially with powerful CPUs. This tiny fan blows air directly onto them, like a personal air conditioner for your motherboard's power delivery, keeping them cooler and more stable.
Alternatives
If this block's flow restriction is a concern, look for water blocks specifically marketed for low flow restriction or those with a simpler internal design. If you need integrated liquid temperature monitoring, seek blocks with a built-in sensor or dedicated sensor ports.
