Northbridge Chipset ????

Hi,

I am about to put my new pc together. I have the K8V with a 3200 AMD. I
bought the Zalman CNPS7000A-CU CPU cooler. My question, is there anyone
that adds a cooling heatsink and fan to the Northbridge Chipset? I am not
even sure it will fit with the big Zalman.

Asus only has a heatsink on it now.

Thanks,

Carl

Your chipset block diagram is here:

http://www.via.com.tw/en/k8-series/k8t800.jsp

The Northbridge has less than the normal amount of functionality
in it. It doesn't drive the memory on your board - it interfaces
to your AGP card, and passes data from the front side bus to the
Southbridge. There is no graphics or 3D stuff inside the
Northbridge. While the VIA site doesn't list the power dissipation,
I would think that thing would run reasonably cool, compared
to the 10-12W of a 875/865 Northbridge.

Why not assemble it and run a 3D benchmark ? Test the heatsink
with your finger. If you can only hold a finger on the heatsink
for 2 seconds, before having to remove your finger, then the
surface temperature of the heatsink would be 55C or so. That would
be too much. If you can leave your finger on the heatsink all day
long, then it probably doesn't need a fan. (This all assumes
that the heatsink has enough thermal interface material between
the heatsink and the chip. You can inspect for that visually
without having to tear the heatsink off.)

Wait and see,

if ur in the UK - try
http://store.over-clock.com/Memory_Chipset__Case_Cooling.html. i`m using the
microcool Northpole. (a7n8x board). there avaible for both AMD and INTEL
northbridges, and cool very nicely. also come with mosfet + pll heatsinks.
it's about 2" tall, with a 40mm fan ontop.

alternatively, theres the iceberq vga/northbridge coolers. not had
experience with them so i cant comment on their performance - but are meant
to be relitively good.

Then put the Zalman onto the CPU and leave the northbridge alone. It's
very unlikely Asus put an inadequate heatsink there. Active cooling
would only get you more unnecessary noise.
