GT500 Powerful Turbo-Fan (4200 RPM) Laptop Cooling Pad — Infinitely Variable Speed, Seal Foam

Dual-core cooling system: an industrial-grade turbofan (4200 RPM) paired with a combined sealed foam delivers strong cooling performance. The design provides 360-degree undifferentiated cooling, so the pad cools effectively regardless of where your laptop’s vents are located. Variable speed control: the fan speed is continuously adjustable from 0-4200 Rpm to match different usage — set the optimal RPM for light office work, demanding gaming, or quiet standby. Rear-exhaust friendly: a bottom air-intake layout prevents heat from flowing back into laptops with rear exhaust vents, addressing backflow concerns. Adaptable seal foam: the combined sealed foam can be positioned to suit your laptop’s size for the best airflow contact. Compatible with 13-17.3 inch laptops. Performance vs noise: GT500 is built for performance using industrial-grade turbofans — higher fan speeds produce better cooling but also more noise. Noise level can reach 55 dB at maximum speed; by comparison, normal conversation is about 50dB. If you are sensitive to noise, please buy carefully.
