anyone else have this problem, i just installed a thermaltake smart case fan 2, it worked fine when i powered up the machine, then i decided to put the sensor onto it... i thought everything was going fine, when i opened up the case the fan wasnt moving and the sensor fell out. i dont know if this is a problem, but i powered off the pc, put it back in the cpu, when i turned on the machine, no go. i took the sensor off and just let it go full speed, turn the machine on, no go. do i just have a defective fan or did it burn out or something...
