NotebookCheck noted that the laptop delivers stable gaming performance but also observed that fan noise can become quite loud under heavy load. (Notebookcheck)

The larger chassis gives the cooling system more physical space compared to smaller gaming laptops.

This improves:

• Sustained performance
• Thermal management
• Reduced throttling

A Reddit user reported CPU temperatures around 79–80°C and GPU temperatures around 70–75°C during demanding gaming sessions. (Reddit)

These are respectable thermal results for a high-powered gaming laptop.

High Refresh Rate Competitive Gaming

The 240Hz refresh rate display is one of the strongest gaming features of the Strix G18.

High refresh gaming significantly improves:

• Motion smoothness
• Input responsiveness
• Competitive reaction times

Fast-paced esports titles especially benefit from high refresh rates:

• Valorant
• CS2
• Apex Legends
• Fortnite
• Overwatch 2

Competitive players often prioritize frame rate consistency and response speed over graphical fidelity.

The Strix G18’s powerful hardware can push very high frame rates in esports games, allowing users to take full advantage of the 240Hz display.

This creates a smoother and more responsive gaming experience compared to standard 60Hz or 120Hz displays.

Mechanical-Style Gaming Keyboard

Gaming laptops require responsive keyboards for fast gameplay.

The ROG Strix G18 includes:

• RGB backlighting
• Fast key response

Battery Life and Portability

Gaming laptops traditionally struggle with battery life.

The Strix G18 performs reasonably well for its category, although gaming on battery power remains limited.

NotebookCheck described the battery life as “decent” for a high-performance gaming laptop. (Notebookcheck)

However, users should understand that maximum gaming performance still requires AC power.

Portability is also relative.

The Strix G18 is significantly larger and heavier than ultrabooks, weighing approximately 2.9 kg according to NotebookCheck. (Notebookcheck)

This device functions more like a portable desktop replacement than a lightweight travel laptop.

Potential Drawbacks

Despite its strengths, the Strix G18 does have some limitations.

Potential concerns include:

• Heavy chassis
• Loud fan noise under load
• Premium pricing
• Large power adapter
• Limited portability

NotebookCheck specifically criticized the fan noise levels, stating that the fans remain audible even during lighter workloads. (Notebookcheck)

There have also been reports involving ASUS ROG firmware-related stuttering issues on some models. ASUS acknowledged these concerns and released BIOS updates to address certain problems. (Tom’s Hardware)

While not every user experiences these issues, buyers should ensure firmware and BIOS updates remain current.
