Thermaltake Hardcano 13 A2259 Multifunction Fan Controller
 

"While the Hardcano 13 is not for everyone, the PC enthusiast wanting a device to monitor multiple system temperatures and control up to four fans would have to look long and hard to find anything better. Throughout several days of testing, the device performed flawlessly and exceeded my expectations in a number of respects."
