Evaluating the thermal and acoustic performance of Razer's latest Blade 18, featuring the RTX 5090: Is this high-end gaming laptop prone to overheating or genuinely superior?
The tech world is abuzz with the latest iteration of Razer's gaming laptop, the Blade 18 (2025). This powerhouse device, manufactured by Razer, is a must-have for gaming enthusiasts seeking high-performance and sleek design.
Priced at $2,999.99 for a 5070 Ti model, the Blade 18 (2025) is available for purchase on Razer.com. It boasts an NVIDIA GeForce RTX 5090 laptop GPU, which delivers superior graphics performance.
The laptop's CPU, an "Arrow Lake" Core Ultra 9 275HX processor, ensures smooth and efficient operation. However, during intense gaming sessions, the CPU temperature can reach around 84°C, while the GPU sensor can peak at 74°C.
Benchmarking the laptop in 3DMark pushes the fans to 3300 RPM, increasing noise slightly to 54.2 dBA. Interestingly, moving to 3000 RPM sees the noise jump to 52.1 dBA. For those seeking quieter operation, manual fan control in Razer Synapse allows for setting the fans to their maximum at 4600 RPM, peaking at around 66.1 dBA.
In its idle state or while watching a muted YouTube video, the Blade 18 (2025) fans reach about 36.3 dBA while running at 1600 RPM. The laptop's idle GPU temperature is closer to a middling 52°C.
The laptop's internal components, such as the middle of the keyboard and the hinge-mounted vent, can heat up during use. The middle of the keyboard jumps to around 37.8°C, while the hinge-mounted vent exhausts recycled air measuring 44.1°C. During the benchmark in Cyberpunk 2077, the hinge throws out hot air, hitting 59.7°C.
Externally, the "wrist rest" areas of the chassis measure 39.3°C, while the center of the keyboard moves to 43.3°C. The IPS panel of the Blade 18 (2025) reaches around 590 nits at 100% brightness.
Customisation is a key feature of the Blade 18 (2025), with three of NVIDIA's latest RTX 50 Series GPUs available for selection. This allows users to tailor the laptop to their specific gaming needs.
In summary, the Razer Blade 18 (2025) offers impressive performance, customisable options, and moderate noise levels, making it an attractive choice for gaming enthusiasts.
