|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.
