"The original Vantec Nexus NXP201 fan controllers took up one whole 5.25" bay and brought speed control of up to four fans with a nifty blue LED backlit dial. They were blue, they were cool, but they were just too large. Coming in either black or silver aluminum, the panels looked sleek and worked nicely at controlling the fan speed of case fans. Well, that was then and this is now - enter the 3.5" Vantec NXP205 Fan controllers. The NXP205 fan controllers maintain the four dials with blue LED black lights, but this time around the package is much smaller. Packed into a standard 3.5" FDD frame, this fan controller allows the user to adjust the speed of up to four case fans via responsive dials accessible from the front of the computer. The panels come in either black or silver, and blend in equally well with all black cases as they do with aluminum ATX."
