Cooling pad for 14" to 18" laptops

The Razer RC21-02300100-R3UC cooling pad fits Windows and Mac laptops from 14" to 18". It uses a single 140 mm fan inside an airtight pressure chamber with foam seals to prevent cool air leakage. Smart Cooling adjusts fan speeds automatically based on system temperature readings. The unit adds three USB-A ports for extra connectivity.

140 mm fan up to 3000 RPM with custom curves

The high-powered 140 mm fan spins up to 3000 RPM to lower CPU, GPU and surface temperatures. Preset and custom fan curves are managed through Razer Synapse, letting users balance cooling performance against ambient sound levels. Razer Hyperboost raises sustained power limits on compatible Razer Blade laptops.

Three USB-A hub and remappable controls

A built-in three-port USB-A hub lets you connect peripherals without occupying laptop ports. Multi-function buttons on the pad allow on-the-fly fan speed and Chroma RGB lighting changes, or can be remapped for volume control and app launching via Synapse. The pad measures 15.6" x 11.5" x 4.49" and supports laptops up to 18".

Questions about this item

How do I set up the 140 mm fan and 3-port USB hub on my 15.6" laptop?

Place the laptop on the pad, connect the USB cable to power the 140 mm fan and enable the 3-port USB hub, then install Razer Synapse to configure Smart Cooling and custom fan curves for your 14" to 18" device.

What maintenance will the 140 mm fan and foam seals need over time?

Periodically clean dust from the 140 mm fan intake and blades with compressed air, and inspect the foam seals that form the airtight pressure chamber; replace them if they lose elasticity or no longer seat tightly.

At what point does the 3000 RPM fan hit its thermal limit during extended loads?

The 140 mm fan spins up to 3000 RPM inside the airtight pressure chamber; sustained heavy loads will eventually reach the maximum airflow the single fan can deliver, at which point component temperatures stabilise at their highest sustainable level.
