Does this fan for Nintendo Switch 2 actually work? | JSAUX Cooling Fans Real Test
5Recently, Nintendo's Japanese support account on social media X warned us to be careful when playing with our Nintendo Switch 2 in very hot environments, recommending using it in environments between 5 and 35 degrees, as otherwise the console could overheat and malfunction. The reason for this message is that temperatures above 35 degrees were recently recorded in Japan, so they also asked us to be careful when using it outdoors.
As if by coincidence, we just received the "Cooling Fans" accessory from the manufacturer JSAUX, a device that cools our console and thus prevents it from overheating. Will it be effective? We'll see it in this video, where we unbox the JSAUX external cooling system for Nintendo Switch 2 and review its technical features, remembering that the manufacturer states it should lower the temperature of our console between 3 and 8 degrees. Will it succeed? Don't miss our 4 different tests!
Is an external fan for Nintendo Switch 2 really worth it? In this video, we thoroughly test the JSAUX Cooling Fans, analyzing whether they can prevent overheating during the hottest summers. I show you the unboxing, assembly, real-world temperature tests (with and without the accessory), comparisons with other methods, and objective impressions as an advanced user.
