You should open a new thread asking about replacing the fan to see is
someone who owns that motherboard has already done that and recorded any
temperature change. I don't recall where, but I remember reading some
test lab's comment that the fan was a worthless gesture and that a
heatsink was sufficient (as long as the chip didn't also include onboard
video). Since I often wander over to
http://www.tomshardware.com, I
suspect that's where I read it. You see articles like
http://snurl.com/28fm where 12 of 24 motherboards had a fan on the
chipset (but several of those where fans were used were within a vendor
which used a chipset fan on all their models).
It would've been better to state which chipset for which you were
considering removing the fan rather than the motherboard. Not nice to
make helpers make a longer trip by having to go to Asus to find your
motherboard to see what chipset it uses to then head off to the chipset
maker's web site to look up the specs. According to
http://snurl.com/28fn, yours used the VIA KT266A chipset. Asus has a
bad link to VIA but eventually I got to
http://snurl.com/28fo. No
technical specs there. I eventually hit the same dead link that Asus
had when trying to find more detailed info on their chipset. I gave up
and went back to Tom's Hardware site and did a search on KT266A. Of the
matches, and of those that I checked, like
http://snurl.com/28fv, 6 of 8
motherboards with the KT266A had fans. The fact that any had no fan
indicates that it is not required.
However, even those with fans should already have a heatsink on the
chip. You should have just a fan. Or maybe you meant that you would
put on a *bigger* heat sink. Since the original heat sink is already
glued on, you might have problems getting the old one off. I've heard
of some folks using a hair dryer but a heat gun would more narrowly
focus the heated airflow. Be sure to run a fan across the motherboard
to prevent overheating nearby components or the board itself. I've also
heard of folks using dental floss to saw through the glue.
