You read the title right. Thermaltake introduced their Black Element Cyclone Edition gaming mouse, which comes with a small fan that is dedicated to cooling your fingers.
I don't know about you, but I frequently find myself having to use high performance cooling on my fingers when I sit down to game for hours...
The fan is a 30mm design that operates at up to 6,000 RPM. The reported noise level is a whisper-quiet 21.7 dB. That's about the same as leaves brushing along the ground. Highly impressive given the small diameter of the fan. It should hold up pretty well also, as Thermaltake reports it has a lifespan of 50,000 hours, or about 6 years.
The mouse itself is also very good. It has a customizable laser DPI engine of 100-6500 DPI. It has nine macro keys with five different macro profiles, for up to 45 individual macros. It isn't wireless however, as the fan would likely shorten battery life too much. The fan itself plugs into a USB port in the front of the mouse and is removable.
The mouse also has a range of configurable colors that can be set fairly easily. The fan however doesn't light up. One of the coolest features of the mouse though is it's customizable weight. That's right, you can change how heavy it is, up to 22.5 grams, depending on your needs.
Pricing has yet to be announced, but expect it to be in the region of US $100-$130.
