ABit NF7 North Bridge Fan?

Am I correct in assuming that the fan on the north bridge is supposed to constantly be running (the small circular fan there in the middle)?

I was measuing wires for a looming project and noticed the fan not moving so i checked connections and they were in place. I shut down and am on my old system affraid to use it. Anyone else have this problem?

Yes, i wouldnt be using that mobo too much if your north bridge fan isnt running It defently should be... its there for a reason. If you dont want to return/RMA the board, buy a new cooler for it.

I'd get this:

those NB fans die pretty fast. my Abit IS7's fan died after four months and made a whine for two of those months.

he i have the nsf 7 and my nb fan produces weird sound to, but when i try 2 take the fan off by pressing the 2 pins it doesnt come off

It is "glued" to the chip with a thermal pad.
Some of these pins can be removed by pressing on them from the top, then twist them 90 degrees. Then carefully lift one side of that fan until it comes off. (you could use a 90degree angled flat screwdriver for that. Don't scratch any wiring around the fan.
Buy the Zalman cooler as per agissi's post, clean up the chip and install new cooler as per Zalman instructions.
