I've just replaced my old graphics card with a Gainward 440MX Pro/600. There is no fan on the card just a heatsink - as a result my computer is wonderfully quiet. The thing I have noticed now is that their seems to be noises coming from the processor when it is active. This especially happens when I scroll down webpages in IE. Is this normal? Never noticed it before, but then there was a hurricane going on in the box.
