Cooling fan for my Geforce 6600 Vid card?

My video card is getting REALLY HOT!! I have a Dell 5150 computer and it only has a intake fan in the front of the case that blows over the CPU heatsink first then over the vid card heatsink so it gets really hot in the case which make the card get hot. Can someone suggest a cooling fan the will fit it.|||You can normally jury rig a mount to hold the fan to cool it. ( Even if you just bend up some coathanger wire.) Get a fan that is a slow rever that way it won't be too noisy.
