Burned out video card fan?

[Guest]

I have an NVidia GeForce4 440 AGP 8x

I noticed it was having some problems, with jagged lines all over the screen
and not being able to change resolutions and such (it has never been a
problem before, it came so suddenly). So I popped open my computer, and found
that the actual fan on the video card, was not spinning, so I immediately
thought it had burned out, and that I had to replace it. But, upon further
inspection, I noticed that the fan moves very, very little, almost
unnoticable. If I give it a push with something plastic (I'm not that stupid)
then it spins about halfway and struggles, then stops. I tried to vaccum it
out (I am very careful, and do this regularly) but it didn't help. I changed
slots on the motherboard, so see if maybe it would help, but nothing.

So my question, Is there a way to like, give it more power, so that the fan
will spin properly? Or is it a lost cause. It's not completely burned out,
there is just something not running right.

Thank you

You need to replace the fan. It sounds like either the bearings or bushings
have gone.

Well, I kept playing with it, and I got it to spin! But I don't know if it is
at full speed (looks like it) and I don't know if after I restart, if it will
continue to spin.

Go spend $3.00 and get a new fan what is hard is finding the one with the
same connector!

Think they would have it at a local Office Max or Radioshack? It is two-prong
connector, and the fan is round (not a square casing) and it's just shy of 2
inches in diameter.

Just take it with you when you buy a replacement, you can't go wrong then.

The problem is that the lubricant has dried up and/or dust has gotten into
the bearings. If the fan was burnt out, it wouldn't spin at all.

In our shop, we usually fix them by carefully removing the fan, peeling off
the label on the back side, prying out the little rubber plug (if present)
and lubing with a few drops of oil. Best to use an oil with silicone or
teflon added. You can get this type of oil at Radio Shack, et al. It comes in
a pen-type container with a needle applicator.

Some of the fans used on VGA cards are practically impossible to find, so we
try this first.
