Two LEDs on fan header Vs molex

post #1 of 2
Thread Starter 
Why when I connect my LEDs to the molex they run fine, but when connected to the fan header the resistors begin to overheat like crazy...

Aren't both sources 5v or 12v?

A fan header is +12v only (unless your able to control fan speed through the mobo). Your led's are prolly on the +5v molex.
