The IETS GT500 V2 (Hub+RGB) has the most powerful fan on this list, with blades spinning at 5000 RPM. No other fan on the guide comes close to this speed, creating a wind tunnel rather than a concentrated stream of air.
The fan is located in the center of the cooling pad. Instead of blowing air into the bottom of the laptop, it spins air around it like a washing machine. This causes what the company describes as “360-degree undifferentiated cooling,” meaning the air cools all parts of a laptop equally.
Additionally, the fan is recessed in a foam-surrounded pit, an unusual design that promotes maximum cooling. The foam creates a vacuum seal with the bottom of your laptop that traps circulating air. Together with the 360 fan, the GT500 V2 can cool even the most powerful gaming laptop. This model also has a three-port USB-A hub and RGB lights for added brightness.
The downside to that high fan speed is that this device is very loud. The loudness of the fan is the main criticism seen in its Amazon reviews. IETS is well aware of this issue and on its product sheet it states that the noise can reach 65 dB and that “if you are sensitive to noise, buy with caution.” They make no secret of the fact that the GT500 V2 sounds like a jet engine. If noise bothers you, buy something else.
