For Synapse 3-supported models:
In Synapse 3, the Razer Blade’s fan speed can be manually controlled in both “Balanced Mode” and “Gaming Mode”.
To adjust the fan speed:
- Open Synapse 3 and select “SYSTEM” from the top bar.
- From there, click on “PERFORMANCE”.
- Select the “MANUAL” option.
- Click and move the node to your preferred fan speed.
Here are some additional notes when adjusting the fan speed in Synapse 3.
- The speed you select will be constantly maintained and no longer be adjusted by the system.
- You can only select between 4000-5000 RPMs. (Gaming mode will only allow 4500-5000 RPMs)
- Selecting a constant fan speed may result in increased fan noise from your system.
- Selecting 5000 RPM will help keep your Razer Blade cooler during intense gaming or other activities requiring increased GPU or CPU usage.
- These settings will be stored and saved as long as Synapse 3 is running.
For Synapse 2.0-supported models:
- Open Synapse 2.0.
- Select “SYSTEM” from the top-most bar. Under SYSTEM, select “POWER”.
