View Full Version : Motherboard Fan circuit DEAD????

21-09-2002, 06:33 PM
I was installing an additional case fan off fan point on my motherboard, and when I turned my machine on for the first time, no fans ran except the power supply. The motherboard, CPU and 2 case fans all running form the points on the motherboard no longer work.

I am now running 4 fans off the points inside the power supply.

What have I fried, and What is the fix, if any.

Thanks everyone.

Karz. You need to check where the voltage breakdown is Check at the fan pins with a meter to confirm you don't have 12 v DC then check at the power supply input to the motherboard to see if you have 12v DC from supply(yellow wire I think) If ok then switch circuit on motherboard at fault normally a trany may have cooked depending on the type of motherboard at to whether that can be fixed easily.

Hey man,

all the fan points have only 0.6v running through them i have a asus A7V266-E motherboard with a VIA KT266A chipset.

I dont know how fixable it will be,
