Does your system have issues like slight noise coming when earphones plugged in, very occasional stutters and even less overclocking than expected? Then this thread is the right place for you.
If you examine motherboards closely especially from manufacturers like Asus, Asrock, Foxconn etc and graphics cards from Sapphire, XFX etc, you will see excess soldering flux and you will find that the PCB does not have the same texture everywhere. It will look somewhat dirty. Example? Here you go. Look inside the yellow rectangles.
Well this is an Asus Rampage IV gene 3 motherboard-High end segment.
What is flux?
Well soldering flux is a semi solid or liquid like thing which helps to reduce the melting point of the solder metal and hence prevents oxidizing of the metal while excessive heat is applied. While manufacturing it is used in plenty and some manufacturers don't care to clean it perfectly as it works "well enough" for customers(Well not me.
)
How it affects?
If you ask me, that soldering flux is a fair conductor of electricity. I have seen it in plenty of applications while trying to make a robot PCB or a speaker amplifier myself. As long as the flux was there, it was malfunctioning. Now that flux is affecting the performance of all the components and ICs installed in the motherboard. Like for example say if you receive noise from your sound card. it may have happened that the output of the card is somewhat very slightly conducted with the 12V rail of the motherboard and hence you receive the feedback.
Now to remove it.
Just remove the motherboard from the chassis because the maximum flux usually stays on the backside.
You will need- Plenty of Isopropyl alcohol, plenty of semi-lint free clothes, toothbrush and in extreme cases soap and water. Remember water never damage electronics alone. It is water + electricity that damage electronics.
Now pour Isopropyl alcohol on the backside of the board and rub the whole board with the brush and clothes. Be careful not to rip off any components if any on the back.
You will get a sticky surface and that will let you know how much excess flux was there.
If it goes away with just alcohol then its ok. Else take some water and soap and brush the back of the board with toothbrush until it goes away. Then dry off all the water and make the back perfectly clean.
You should now get a clean powered motherboard and should be able to overclock more than before.
I tried this in all the motherboards that I owned and even of my close friends. And for the proof, see my overclock of the CPU, IMC and the RAM.
Cheers.
