Looking for a replacement ABIT KT7A chipset fan

I've got a PC with an ABIT KT7A motherboard, and the fan has started to
get noisy. It seems that all the fans are failing at once -- the PSU
was sounding terrible, so I replaced it, but the system still sounds
bad. I want to replace the little fan that sits over one of the main
chips on the motherboard (it's the north bridge, I think), but it's not
a common PC part AFAIK.

Oiling the bearings/bushing usually fixes the noise. Otherwise, I'd
replace the chipset cooler with a passive cooler.

If you use a bigger heatsink you need no fan.

When the fan on my KT7 (non-A) went out, I just pulled it. Watched my
system temps for awhile and they stayed within limits, so that was that.

Abit seems to have a quality control problem with their Northbridge fans. I
just replaced mine for the second time on my IC7-MAX3. Before this one
smokes, I'll be looking for a passive cooler.

I just replaced the NB fan on my NF7 motherboard with a Zalman ZM-NB47J
heatsink, and the noise that way driving my NUTS is gone! Everything works
as it should.

The best thing is, I did not mave to pull the MB, as many bulletin board
entries say is imperative.

You will need:

1. Small, sharp scissors (surgical would be best);
2. Needle-nosed pliers or something similar (I had some surgical clamps);
3. A very small, Phillips-had screwdriver.
4. Guts, or willingness to risk screwing up your MB.

After removing the two little Phillips' screws that hold down the ABIT NB
fan cover, remove the fan after pulling out the wire to the MB. That will
leave you with the base of the fan on the NB, held in place by two plastic
push pins. The base should move around easily.

If you cannot remove the push-pins simply by pulling on them (one of mine
came out easily just that way), you can cut them away if you have the right
scissors. Use care working around the MB and protect against static. You
may have to push the end of a pin into the region below the MB.

Once the pins are gone, you can remove the old fan base, clean the old
grease off the NB, and install the cooler.

This took me about 90 minutes today, start to finish. Temperature is fine,
and the machine handled graphics on Battlefield 2 (the ultimate test!) just
as it did with my sickly fan.

Chas. -

Why did you choose the ZM-NB47J over the ZM-NB32K? Greater mass (and
therefore, presumably, greater heat dissipating capacity)?

John, I wish I could say I approached it so scientifically, but the truth of
the matter is that after doing an extensive search on heatsinks, I settled
on it because others were satisfied with the fit and heat dissipation.
Suffice it to say, it works for me! I do not know if it would be less than
satisfactory with a more powerful system.

Thanks. I'l give it a try.
