hey dolph,
i had a similar problem with my northbridge fans on both my old ga-7dx and my current ak31a. the general consensus is that this fan is not really necessary if ur not going to overclock as long as u have decent air flow through ur case. as for the video card, while i can't personally relate, people have reported swapping their heat sink and fan with a blue orb. u may want to look into that.
hope this helps.
