Leadtek 5900LX Overheating!!

I purhcased my Leadtek card some time ago now, and they're quite a rarity these days. Since I got it I've overclocked it using the Winfox program which came with it, and this caused my card to overheat somewhat. I decided to put the clock speeds back to default 400/700, but the card still gets real hot. I ran 3dmark2003 and felt the card itself with my hand, looked at the card's temps and it read 67 degrees. Is this normal? or do I have a point?

If anybody knows about my problem and could help me sort it please help! :)

What do you have the AGP voltage set at? I guess you dont have any voltage mods done.
What is the air flow in your case like? and has the fan got covered with dust? or is actualyl working?

Just overclocking teh card, not increasing the voltage will make very little difference to the overall temperature. Is there a new BIOS out that you can flash?

Is the fan properly connected to the card?

Just a few questions ;)
Will.

I havn't changed the voltage as I dont know how lol. Ive got an Antec SuperLanboy case, so its got 2 120mm fans front and rear, front sucking and rear blowing out. the case fans arent covered in dust, but im not sure about my gfx as it has 2 40mm fans enclosed in grills. I'm not sure how to flash cards si I'm not sure about that :)

let me know what you think, thanks alot, JamesD.
