Instead, the little 40mm angled fan (NF-A4x10, the smallest in Noctua’s catalog) cools off your hand through the mouse’s speed holes. PulsarThe mouse itself is fairly typical of the excessive design you often see these days. Standard shooter configuration with two thumb buttons, “carbon composite” body, aluminum alloy wheel, optical switches, 42,000 DPI, 8,000Hz polling rate, 70 grams. It lacks dedicated DPI and polling rate buttons, but the wireless receiver has buttons for those. The mouse costs $180 on Pulsar’s site, a hefty premium over most of its other designs.
