Something is wrong with my molex

post #1 of 19
Thread Starter 
confusing read right here

some run at 12 volts others dont?

my fan controller lights look as bright as ever but my fans even at full speed look like they are running at 8ish volts

when i connect my rad fans to any molex they run full speed, when i connect my pump they run at full speed

when i connect my fans to fan header 2 it runs at full speed but my first fan header runs like at half speed

is it because my rad fans and pump are taking up all the current?
but if i add any fans to the rad fan series they run fine

im not sure why my fans are all running at different speeds

have you looked at the fan settings in the bios? maybe fan2 is set a lower speed? are you trying to run all of that on one molex line from the psu? you need to try to distribute the power as evenly as possible (try to use every molex connection and cable that came with your psu to spread the current). how many fans are we talking here?

im using an external power supply sill i can figure out why its like this. i mean i have my power led on the same series as my fan controller and it looks the same brightness weather im using my molex from comp or a separate power source
