southbridge cooling on NF7-S

I've been reading a lot of posts about cooling the southbridge if you start
to o/c a NF7-s with a Barton 2500+. Now my question is how to you attach
it? I assume you'd use some adhesive or something........what about
throwing on some ASIII as well or will that not work? At the moment l'm
looking around for a nice 40mm HS. I assume there is no need to add a HS if
you don't up the chipset voltage.

Thanks

Some people use thermal pads to stick a HS to the Southbridge. Others use
Thermal Glue, the type that hold HS's o a Graphics Card - be aware that this
isn't going to be removed once fixed and so could invalidate your warranty.
I have built nine different systems around a n-Force 2 board and not put any
cooling at all on the Southbridge chips. Nor have I removed the Northbridge
HSF to put extra gunk on it nor have I lapped the chip. All the systems that
I have built have been fine and all are running at 200mhz +.
The two that I own, one of them an Abit the other an Asus, are both ok and
remember that the Asus doesn't even use a fan on the Northbridge they have
just a HS. The Abit has been perfectly stable at 220mhz FSB and even ran at
230mhz but at that speed the memory was not in sync.
Remember when the FSB is raised the Southbridge does not run any faster.
My position is since they were made without HSF's for all climates then
there should not be needed at all. 200mhz is within spec for the chipset.
Other people do feel the need to lap the Northbridge and refit the HSF, buy
and fit HS's for the Mosfets and Southbridge chip, and I'm sure that that is
right for them.When I ran at 230mhz increasing the Chipset voltage did
nothing for stability and made no difference. Increasing the VDD voltage did
allow me to use tighter memory timings at higher speeds.

You could always use a 120mm Fan blowing in from the side onto the area over
the SB if you want or just do what I do and not bother

The southbridge on my NF7-S runs to a good high temperature...I'm tempted to
put some kind of heatsink on it but haven't yet.

As regards the northbridge, I think there are good reasons to do some work
here (I certainly wouldn't lap the chip, though). When I removed the stock
Abit HSF the factory application of goop covered less than a third of the
chip. You can clean this off an reinstall the stock active cooler, or use
one of the Zalman passive heatsinks which is what I did. Works great - the
stock heatsink used to get hot enough to cause discomfort after a second or
two...the Zalman stays pretty cool and does away with the fan (and therefore
at least a little system noise).

Just my thoughts. YMYV

I added a small (40 mm) heatsink with fan to the southbridge using thermal
tape that came with the heatsink/fan. It works fine. You don't need
excessive cooling abilty; just enough to cool it down a bit, so thermal tape
is fine.
