Fan noise when I connect to my TV via s-video

Ati Radeon x1600 pro 512mb agp

Specs: Windows Vista
The fan in my graphics card is speeding up very fast and slowing down, then speeding up, slowing down continually when I plug the s-video cable into my TV to watch MLB-TV. How do I stop this laboring whinny noise? I'm pretty sure it is the graphics card fan making the noise because the noise goes away after I disconnect the s-video cable from the TV.

Sounds like it is using more GPU cycles to convert the Digital Signal to Analog for your S-Video. What kind of TV do you have? Doe it not support DVI or HDMI connections?

My TV is an HDTV and does have HDMI (but not DVI), I chose not to buy an HDMI cable because of the expense for a 16 foot cable which I needed to reach the TV.

Well you get what you pay for. S-Video is old tech and only supports 500x500 res which is only slightly better than 480i. If you want to watch something off your computer in HiDef then you will need the HDMI cable.

As for your fan, you could get a new graphics card with a quiet fan or replace the fan on the card but that will void the warentee. You could also try taking control of the fan through an application like speedfan...

but this too will void your warintee because by slowing your fan it will cause damage to the card.

I would probably upgrade my Graphics Card and use HDMI cable because graphics card may do the same thing on HDMI.
Have fun with that. Better to pay the little extra to do it right.
