Not sure if this is correct section to post in. My specs are as follows:
AMD 3800+ X2
Asus A8N-E mobo
I recently purchased a second hand MSI 3870 OC gpu to replace my 7900GT. The card is working fine (tested in another pc).
In order for the card to fit in the mobo the Northbridge heatsink must be removed entirely. Since my pc is not overclocked I wanted to know if removing the Northbridge heatsink would cause the pc to overheat and possibly blow the board.
Socket 939 mobos are hard to come by these days and buying a new mobo and cpu is out of the question at the moment.
There is no Northbridge chip on the A8N-E. The chip you're talking about is the nForce4 Ultra chipset/MCP (Media Communications Processor).
There is a reason why there is a heatsink with a fan attached to that chipset. It's because the chip package itself cannot dissipate all the heat produced during its operation to the surrounding air due to insufficient chip-to-air surface area. Remove that heatsink and fan and you will run into stability problems very quickly.
