Noisy Northbridge cooling fan on a Gigabyte GA-8AENXP-D - Help please.....

I have built a PC using a Gigabyte GA-8AENXP-D motherboard and am generally happy with it, but the Northbridge cooling fan is very noisy. I want to find a quiet fan to put in its place or gather advise about the safety of using a heatsink.
Any pointers in the right direction would be gratefully received.
Thanks in advance

Chances are this isn't the source of your fan noise, but I just finished troubleshooting a sudden increase in fan noise on my old GA-SINXP1394. It turned out that my noise was coming from the 40 mm fan attached to the chipset heatsink.

Or at least that's what I thought until I removed the fan. I found that the fan wasn't making any noise. It seems what I was hearing was actually a vibration noise caused by the fan working its way loose from the heat sink. I was surprised to find that the four screws attaching the fan to the heatsink do not not fit into nuts on the heatsink. Instead, the threads of the screws chew into opposing sides of the vertical heatsink vanes!

I reattached the fan (chewing new ridges in the heatsink) and the noise is gone.

Not an example of quality manufacturing IMHO...
