Well, if your normal tasks don't load the GPU heavily, then try inserting a
resistor in the GPU heatsink fan power line (or a rheostat if you want to
experiment) to limit the fan speed. It will never run a full speed, but
that shouldn't be a problem if the GPU is never heavily loaded.or you could
use a Zener diode and a suitable resistor to limit the fan to, say, 35%
under all conditions. And even use an external switch to choose a 35% limit
for start-up and DOS operation, but flipping the switch for Windows XP
operation to allow the nVidia driver to run the GPU fan at any speed,
depending on GPU temperature. I happen to use a rheostat controlled fan to
cool my hard drives (a 120 mm fan fills the front part of four half height 5
1/4" bays) with the rheostat mounted in an unused bay on a snap-in cover
panel (the case has nine 5 1/4 front accessible bays.)
I'd bet that at your location you might get away with just limiting the fan
to 35% all the time, consider your ambient temperatures have go to be a lot
better than the 95 F ( 35 C ) I must contend with in Atlanta and South
Florida during the summer.
