Some say they can’t feel the sensation of the fan, but it seems working just fine in our testing. With that said, the speed it runs at seems sufficient to produce a gentle cooling effect which radiates off the mouse. There’s not a way to adjust it manually, only turn it off if desired. By default the fan runs constantly at a set speed.

Perhaps the number one question regarding this mouse is how the fan works, and if it’s effective. It’s not as light as some other gaming mice, but it strikes a balance between being lightweight and not so light that it feels cheap. In total, the mouse weighs just 75 grams. In keeping with the light form factor, the bottom of the mouse also features many cutouts. The cutouts in the black (or white) plastic extend a bit beyond the palm area to the left and right buttons, as well as on the left and right sides of the mouse. The first thing anyone is bound to notice is the open back design which showcases the LED fan front and center. The Zephyr Pro stands out straight away with its design. This latest version ensures this is both fun and functional mouse.

This is the Zephyr Pro Gaming Mouse which iterates upon the basic concept. Since then, the company kept working on the concept and now released an upgraded version. This was a lightweight gaming mouse with a built-in fan to keep palms cool. Back in 2020, Marsback launched a Kickstarter campaign for a most intriguing device: the Marsback Zephyr Gaming Mouse.
