Northbridge/Southbridge mod

 

Time -- 15 minutes

I am not responsible for the damage that could happen during modifications.

 

The northbridge and Southbridge chipsets on motherboards play an important roll for you computer. The north takes care of front side buss communications between RAM, AGP and your processor. The southbridge takes care of onboard components such as : network interface, sound, serial and parallel ports. They can become just about as hot as your CPU. The cooler we can keep these chips, the longer your motherboard is going to last. Also with better cooling you could overclock your front side buss (FSB) at higher clock rates than normal.

Let's do it:

 

All parts we will need:

-Motherboard
-Arctic Silver V
(Optional) (or your choice of thermal compound)
-Rubbing Alcohol, fingernail polish or Windex

-Needle nose pliers or hemostats
-Rag or cloth

 

Take a look at your motherboard. You will notice the northbridge and maybe a southbridge. My K7S5A does not have a southbridge visible. You may have just a heatsink like this one, or it may just be the chip without any thing on it what-so-ever.

If you do have a heatsink on the northbridge it could be the type like this that just "sticks" to the NB. Or you may have the type that uses spring loaded pins to keep it in place.

If it's just like mine and just "sticks" to the chip, your going to have to run your system through benchmarks, or play heavy games for a while to make it nice and hot in order to remove it. Once it's good and hot, just start to twist it back and forth. This may require some force, or require a chip puller. It will eventually "pop" off. Now, if you have the spring loaded type, you will have to remove your motherboard from the case to get access to the back and squeeze the pins so they can go through:

Once the heatsink is off, you will find the generic "thermal pad" or thermal grease. Get some Windex or rubbing alcohol (nail polish remover), spray it on the sink and let it soak:

While this is soaking, spray some "cleaner" on a cloth and start removing the "garbage" off the chipset itself.

This stuff is hard to remove sometimes. Keep at it until both heatsink and chipset are good and clean.

Once clean, use some Arctic Silver V on the chipset.

 

Use very little and spread it to thin layer. If your heatsink/motherboard does not use the spring-loaded pins, then do not cover the outer four corners:

Use very tiny drops of super glue on the outer four corners.

If you DO use the spring-loaded clips, cover all of it with Arctic Silver:

 

Once this is done, you can put it all back together. However, if you want even better cooling it's time to add a fan. If you have an extra 40mm fan and some screws laying around, use these. There is usually some way to "jimmy" the fan so it stays on the sink:

The right size of screws will fit inside the heatsink's fins.

 

If you do not have extra fans laying around, I would recommend the Vantec Iceburg cooler. Instead of using your stock heatsink.

 

Obviously if your system already has a nice heatsink/fan combo for your chipset, you only need to clean them and use Arctic Silver paste instead.

Be sure to look for the southbridge on your motherboard as well, and give it the same treatment.

 

To gain better cooling you could always lap your sink before putting back on your chipset's.

Now get out there and MOD!
