I run a cooler master seidon 120v water cooling system and i have i use dual 120mm fans. One is a molex connected and the other is the stock 4 pin that plugs into the mobo. The one plugged into the mobo just randomly shutdown. Didn't worry me because of the second one so i went to my open hardware monitor program and right clicked the fan and switched the control option to manual 40% it kicked back on then i switched it back to defaul and it shut off, so i switched it to manual and closed the program and the fan died. Any suggestions?

The one connected via molex is set to 100 percent all the time. The other one is getting controlled by something, your motherboard or some program you have installed. Since it turns back on when you manually tell it to, it sounds like your fan profile you have set is to shut the fan off below a certain temperature, and your computer is below that temperature.

what brand is the motherboard? I know with Asus in particular, the Fan Xpert software can test an individual fan for its min/max speeds (done manually with "Test" button). only downside is if you switch to a different fan, the software won't automatically adapt. I'm sure other brands have similar software with similar characteristics.

although... there may also be a setting in bios to change the fan between voltage or PWM control; if its a 4-pin fan it should definitely be PWM controlled.
