Overclockers Online has published a review on the Ultra Fan Commander w/Thermal Sensors
You really cannot compare the Fan Commander to many fan controllers on the market as nothing can shake a stick at its ability to control seven fans. If you have a case with more fans than PCI slots like me, then the Ultra Fan Commander is a must. The ability to finally control all the fans in my case at one central location is priceless. My computer has never been so quiet when I am not working it hard and the security of the alarms built into the Ultra Fan Commander let me rest better than I have before with my computer running through the night. That is, until a fan dies and I am thrown from my bed from the amazingly loud alarm going off at three in the morning, but it will be worth the interruption as I would rather be safe than sorry.Ultra Fan Commander w/Thermal Sensors
