southbridge is the chip tat control the onboard sound isn't it? so i think most of u all got a pci soundcard on. so off the southbridge. not much use also. OC kaukau won't effect the southbridge. correct me if i'm wrong.

thats true biggrin.gif there is really no point cooling down the southbridge.
and the mosfets.....it doesnt help to cool it down coz the surface of the mosfets aint heat conductive. it will only help when the mosfets are really damn hot.

u guys talk about msofet cooling, have you guys ever wondered and counted how many mosfets are there on your mobo? its not always the case that the mosfets surrounding your cpu are the mosfets that are causing the vcore to fluctuate.

if u seriously no idea how a mosfte look like, its like this :

every single component that looks like that = mosfet on your mobo.
and which mosfet regulate the vcore? = ask your manufacturer.

the mosfet's surface is made of non/least heat conductive material, it gets warm though but the heat is contained within. an anology of how it is:

mosfet surface = wood
internal part of the mosfet = kettle

the kettle cour get very hot, but the heat doesnt transfer much to the wood, u can place heatsink there...but the effect is almost zero.

True in theory..and the back of the mobo cooling thing...

But anyhow, why does SMP boards always have big heatsinks for their mosfets?

colling the mosfets from the bac of the mobo very damn mar fann ler....and it has to use thermal pad, and if something went wrong...sot kiu the mobo is really a nightmare jsut because of trying to cool something that is not really confirmed to have any real effect on the performance....its like doing research for peopel for free lol in your own expense of coz tongue.gif

which smp board? it might not be a mosfet....something with mosfet look biggrin.gif
or they have bare mosfets smile.gif
