I own a Gigabyte 7N400Pro mainboard, which I currently use for gaming.

The Northbridge fan does not work when my videocard is connected, appearantly, it draws too much power even though it is FED by the Power Supply Unit. I have allready been sent another fan by Gigabyte and replaced it a very long time ago, but I recently noticed that the fan has NEVER worked with the videocard in place. (I am not looking to make it work, as I have another idea)

The northbridge fan becomes very hot without the fan.

Here is the idea I have:

First, a picture of the mainboard I use. The Northbridge fan is located underneath the AGP 8X logo which is a fan with a small heatsink hold onto the mainboard by two white plastic pins.



1. What is underneath the Northbridge heatsink?
2. How do I remove the northbridge heatsink?

If I were to take an older AMD COOLER, as shown below,

(An image of a cooler similair to the standard cooler has been included for the sake of reference)



and use a type of thermal glue to fasten it to the northbridge, connect the fan to the PSU and remove the metal clamp, would this have any effect at all?

1. I know that in the past, there was thermal glue that would not let go. Is this still being fabricated?

2. Would the Northbridge be able to tolerate the heatsinks weight?

3. Is this far fetched?

4. If this is IMPOSSIBLE to realise, could I remove the videocard heatsink (9800Pro/standard cooler) and glue the cooler onto the videocard?These you may wish to consider also>

I fitted an AMD retail heatsink to my Northbridge - had to trim it a little first (using a hacksaw). Drilled two holes and bolted it to mobo, with plastic washers underneath because PCB tracks ran very CLOSE to the holes. I noticed the top of my Northbridge (KT333) was slightly concave (I think this is normal) so thermal paste wouldn't have given good contact. I left the AMD heat pad on the heatsink and used that instead.
